Efficacy of absorbable vs. non-absorbable patient-specific, 3D-printed implants for the treatment of facial bone fractures: a systematic review and meta-analysis.

This systematic review and meta-analysis compares the efficacy and complication rate of absorbable versus non-absorbable 3D-printed, patient-customized, maxillofacial implants in facial trauma patients. A comprehensive search of four databases (PubMed, Scopus, Web of Science, and Cochrane) was conducted. A systematic review and single-proportion meta-analysis was conducted employing PRISMA guidelines. A comprehensive search of four databases (PubMed, Scopus, Web of Science, and Cochrane) yielded a total of 4087 results. After removing duplicates, 16 articles underwent full-text analysis, with 13 meeting the inclusion criteria. The inclusion focused on primary clinical data involving 3D-printed, patient-specific implants for facial bone fracture restorations. Exclusion criteria removed studies without full text, ongoing studies, animal studies, and studies not utilizing CAD/CAM for their implants. A total of 114 patients underwent insertion of 3D-printed implants. Patients receiving non-absorbable implants had a success rate of 84% (95% CI: 74-91), with complications in 12 patients. Patients receiving absorbable implants achieved a 100% success rate (95% CI: 0-100), with zero complications. The study suggests absorbable 3D-printed implants provide superior results with fewer complications compared to non-absorbable 3D-printed implants for the treatment of facial fractures.

Transscleral Pars Plana Choroid Ablation Using the Iridex Laser System Yields Improvements for Surgical Insertion of the Port Delivery Implant in a Minipig Model.

To evaluate an alternative surgical approach for Port Delivery System with ranibizumab (PDS) implant and a novel application of Iridex laser system in Gottingen minipig model. A total of seventeen male minipigs (Part 1: 9 animals in non-recovery and Part 2: 8 animals observed for 8-days post-surgery Part 2) received PDS implant insertion into each eye. The effect of Iridex 810 nm infrared diode laser with varying energy (power or duration) on transscleral pars plana ablation, surrounding ocular tissue and postsurgical vitreous hemorrhage (VH) was investigated. The most effective laser parameters for transscleral pars plana ablation in mitigating vitreous hemorrhage with no surrounding tissue damage were continuous wave mode, 1750 mW, 1000 ms, and 16 spots (8 overlapping spots/sweep applied over 2 rows) across a 4 mm segment, posterior to the limbus, delivering a total energy of 28 J. Minimal self-limiting scleral hemorrhage was observed with two of the implants and no VH were observed. µCT imaging was consistent with clinical ophthalmic. On microscopic observations, no tissue damage was observed at these laser settings. This Göttingen minipig model demonstrated a novel application of Iridex laser for transscleral pars plana ablation that streamlines the PDS implantation surgery.

When Nature Prevails Over Science amidst the COVID-19 Pandemic: Spontaneous Healing in an Infected Nonunion Femoral Shaft Following Stage 1 Masquelet Technique

Managing femoral shaft fractures with infection and bone loss is challenging. The Masquelet technique, a two-stage approach, typically requires both stages for effective healing. Here, we report a rare case of spontaneous healing after only the first stage. A 54-year-old male presented with infected nonunion of the femoral shaft, 8 months post intramedullary nailing for a closed fracture at another institution. Radiographs showed nonunion with osteolysis and screw backout. Implant removal, debridement, and insertion of a PMMA cement spacer with vancomycin were performed, revealing an 8 cm bone gap. Due to noncompliance, the LRS was replaced with a functional brace. After 14 months, radiographs showed complete bridging with callus formation. The spacer, displaced submuscularly, was surgically removed. This rare case demonstrates spontaneous healing in an infected femoral shaft nonunion, highlighting the body’s regenerative potential.

Placement of dental implants using 3D surgical guide

Background. The procedures of dental implant application can lead to optimal clinical outcomes, being simplified by the guided implantology protocol. In the latest articles from specialized literature it is said that digital planning of implants ensures the most accurate diagnosis of the area where the implant will be positioned, with clinical benefits including reduced operative time and a lower rate of complications, all of which can ultimately lead to better acceptance and greater patient satisfaction. Case report. A 55-years-old female patient came to the clinic for a full mandibula rehabilitation. In this situation, the patient wanted a solution using only fixed restoration so the treatment plan that the patient agreed to was an all-on-X restoration. Aim. Given the constant evolution of technology, along with the development of dental technical laboratories, this paper wants to prove that the latest technology can help doctors in placing the dental implants accurately and in a more comfortable manner for both the patient and the doctor. Material and methods. For this case, the insertion of dental implants was performed using the static approach, which refers to the use of tissue-supported surgical guides; this replicates the virtual position of the implant directly from the data provided by Cone Beam Computed Tomography (CBCT). This information was converted into a surgical guide that was used during the surgical procedure. Before the surgical intervention, a CBCT scan was performed, which was used along with the patient's intraoral scanning to establish the ideal position of each dental implant. After the surgical intervention and after the complete healing, another CBCT scan was conducted. Thus, to analyze the accuracy of dental implant insertion, radiological investigations were compared to see the differences between the ideal situation planned before the surgery and the situation resulting from the surgery. Results. The results demonstrate a high degree of accuracy in the insertion of dental implants using the three-dimensional surgical guide, without significant positioning differences. Conclusions. These outcomes support the main purpose of three-dimensional surgical guides, namely the conservation of anatomical structures at the level of the dento-maxillary system.

The Influence of the Degree of Dental Implant Insertion Compression on Primary Stability Measured by Resonance Frequency and Progressive Insertion Torque: In Vitro Study.

Background: This study aimed to evaluate the primary stability, according to the insertion torque value (ITV) and resonance frequency analysis (RFA), of dental implants placed in standardized blocks of bone quality equivalent to type II-A bone, using three surgical undersized protocols of 0.2 mm, 0.5 mm, and 0.8 mm, considering different dental implant diameters and lengths. Methods: One hundred and twenty dental implants (DIs) of different diameters (3.5, 3.8, 4.5, and 5.0 mm) and lengths (8.5, 10.0, 11.5, 13.0, and 15.0 mm) placed in polyurethane blocks equivalent to type II-A bone, according to the Lekholm and Zarb classification modified by Rosas et al., were examined with three surgical protocols of under-milling of 0.2, 0.5, and 0.8 mm. The ITV and the RFA were the determinants of primary stability, and their respective values were recorded as Ncm and the implant stability quotient (ISQ) immediately after the placement of the DIs. These were evaluated according to each surgical insertion protocol, length, and diameter of the DI under a multivariate analysis model (MANOVA). Statistical significance was set at p < 0.05. Results: It was observed that the average of the ITV was significantly higher when a 0.8 mm under-milling protocol was used (63.2 ± 14.9 Ncm) (p < 0.001). However, the ITV was significantly lower when a 0.2 mm under-milling protocol was used (25.1 ± 8.3 Ncm) (p < 0.001). On the other hand, the ISQ did not present significant differences (p = 0.166) when comparing the 0.2 (67.6 ISQ ± 5.4 ISQ), 0.5 (65.8 ISQ ± 3.4 ISQ), and 0.8 (65.7 ISQ ± 4.0 ISQ) under-milling protocols in the evaluation of the primary stability of the dental implant. The multivariate effect size (ηp2 = 0.639) indicated that the variability detected in the insertion torque and the ISQ, at the same time, was explained by 63.9% (p < 0.001) due only to the compression protocol, while the implant diameter explained this variability by 27.0% (ηp2 = 0.270) (p < 0.001) and the implant length only significantly explained this variability by 12.1% (ηp2 = 0.121) (p = 0.030). Finally, any interaction between the compression protocol, implant diameter, and length did not influence insertion torque variability or the ISQ (p > 0.05). Conclusions: It can be concluded that when the surgical protocol for subpreparation is optimal according to the prepared bone bed, regardless of the diameter or length of the dental implant used, primary stability was assured according to the ITV and the RFA in 63.9%. This finding allows us to recommend carrying out a correct analysis of bone quality in order to subsequently select the most appropriate surgical protocol for the subpreparation of the bone bed to achieve better primary stability of the dental implant.

Measurement of bone deformation and insertion torque during dental implant installation.

Insertion of dental implants causes bone deformation and induces residual bone compression stress, which can lead to implant failure if the bone loss threshold is exceeded. The current literature about bone stress is restricted to computer simulations and implant primary stability measurements after installation. This work measures the torque and deformation during implant insertion testing. The aim of this work was to analyze the influence surface treatment, thread profile, body shape and the presence of microthreads in the neck on the primary stability, bone deformation and residual stress during dental implants insertion. The insertion torque and resonance frequency analysis (RFA) are the main technique used to measure the primary stability of dental implants. Five models of dental implants with different surface treatments (machined and acid etching), thread profiles (triangular and trapezoidal) and body shapes (cylindrical and conical) were inserted in synthetic bone blocks (polyurethane) with a density of 30 PCF (0.48g/cm³) compatible with the D2 bone. The insertion torque was quantified by a digital torque driver. Strain gauge extensometry technique was used to measure bone deformation during implant insertion. The bone deformation and torque increase as the number of implants turns insertion increases. Dental implant with trapezoidal thread profile needs higher insertion torque than triangular threads. Implants with a conical shape require higher insertion torque than cylindrical ones. The bone stress induced by machined implant insertion exceeded the bone's mechanical resistance, causing cracks. Conical implants showed better performance than cylindrical ones. The implants with a trapezoidal thread and those with a conical body induce greater insertion torque. Comparing the mechanical behavior, it was found that the machined implants had the worst performance in terms of stress distribution in the synthetic bone, resulting in cracks in the specimen during insertion. Implants with trapezoidal threads and those with a conical body induce insertion torque and bone compression stresses that do not harm osseointegration. Excessive deformations in the peri-implant bone led to bone necrosis and implant failure. Thus, the surgeons must analyze the influence of surface treatment, thread profile, and body shape on the osseointegration process.

Implant-supported prosthesis under progressive loading protocol stimulates alveolar bone growth in patients with severe alveolar bone atrophy. Retrospective case series

IntroductionThe jaw with severe bone atrophy is a difficult challenge when rehabilitating with dental implants. To be able to place dental implants in the most severe cases and to achieve an increase in bone volume by means of the tension transmitted by the load is a novelty. This work provides data on the alveolar bone changes in a severely atrophic mandible that has been treated with implant supported prosthesis under progressive loading protocol.Material and methodsThis study reported on 3 patients with completely edentulous mandible. In all cases, implants were inserted in the anterior region of the mandible and progressive loading was carried out with an increase in the distal cantilever. The length of the cantilever extension was adapted to growth of the residual alveolar bone at the mandible body. The increase in bone height was controlled in the area of implant placement as well as in the area distal to the implants (1 cm behind the last implant).ResultsThis case series described 3 patients where 13 implants were placed. The patients were followed for 17, 19 and 20 years after implants insertion. The mean mandibular residual height of the alveolar bone was 7.8 ± 2.7 mm at the implant site. The mean mandibular body height at 1.0 cm distal to the last implant was 7.0 ± 3.9 mm in the third quadrant and 8.1 ± 4.4 mm in the fourth quadrant. The mean height at the last follow-up was 11.0 ± 3.2 mm (±3.2) in the third quadrant and 11.20 ± 4.4 mm in the fourth quadrant.ConclusionsImplant-supported prosthesis and progressive loading have resulted in vertical bone growth in a series of patients with extreme atrophy of the mandible. The long-term follow-up indicated that bone growth is confined to the dental implants but has been extended to distant regions resulting in the thickening of the mandibular body and the creation of the absent mandibular canal.

Comparison of Full-Arch Intraoral Scans Immediately After Implant Insertion Versus Healed Tissue: A Multicentric Clinical Study

Objectives: The purpose of this clinical study is to compare implant full-arch intraoral scans taken immediately after implant placement with those obtained after tissue healing in patients rehabilitated with implant-supported fixed prostheses. Methods: Between September 2023 and March 2024, a total of 19 patients with compromised residual dentition (6 women; 13 men) were rehabilitated using 4-to-6 immediately loaded post-extraction implants. These implants supported fixed full-arch screw-retained prostheses either in the lower jaw (9 patients) or upper jaw (10 patients). Intraoral scans were taken immediately after implant placement (termed “immediate scan”). After a healing period of four months, the provisional prosthesis was removed, and a second intraoral scan was performed using the same scan bodies and scan pattern as the initial scan (termed “delayed scan”). The two scans were overlaid, and the discrepancies between them were measured. Results: The average discrepancy between the immediate and delayed scans was 0.1905 mm. Our statistical analysis revealed larger discrepancies for implants placed in the posterior areas, with the implant in site 1.6 (Implant 1) showing a discrepancy of 0.2326 mm, and the implant in site 2.6 (Implant 4) showing a discrepancy of 0.2124 mm (p = 0.05). No statistically significant difference was observed when comparing patients treated in the upper and lower jaws. Conclusions: Within the limitations of the study and based on this result, clinicians should be aware that an immediate post-surgical intraoral digital scan for implant-supported full-arch rehabilitations may result in a higher risk of imprecision. Furthermore, according to the results of the study, the accuracy of the digital impression on implant full-arch rehabilitations seems to be influenced by the clinician’s skills. Further studies with larger sample sizes are required to confirm our results.

Simultaneous Osseo- and Odontointegration of Titanium Implants: Description of Two Cases in Human and Animal Models and Review of Their Experimental and Clinical Implications.

Two cases of calcified bone and dental tissue integration with titanium implants are presented, along with a review of the literature on their experimental and clinical implications. First, histological analyses of a titanium implant extracted from a patient with iimplant disease revealed the integration of both dental and bone tissue on the implant's surface. Secondly, a biocompatibility study in an animal model documented two implants in contact with tooth roots. Samples from both animal and human models demonstrated simultaneous osseointegration and dental tissue neoformation, with the latter attributed to the activity of cementoblasts. The literature review confirms the formation of cementum around dental implants in contact with teeth. Certain clinical reports have proposed the insertion of implants into bone sites containing impacted teeth as a conservative treatment alternative, avoiding the need for tooth extraction surgery and demonstrating the successful integration of teeth, bone, and dental implants. Furthermore, the documented natural formation of periodontal tissues around dental implants provided a foundation for tissue engineering studies aimed at realizing implant-bone relationships similar to those of natural bone-tooth structures. The primary challenges remain the long-term preservation of periodontal-like tissue formed on implants and the imparting of functional proprioceptive properties.

Hypoxia-Preconditioned Human Umbilical Cord Mesenchymal Stem Cells Transplantation Ameliorates Inflammation and Bone Regeneration in Peri-Implantitis Rat Model.

The failure of dental implant treatments is predominantly attributed to peri-implantitis, which entails chronic inflammation within the peri-implant tissue, ultimately leading to tissue degradation. Addressing this condition, human umbilical cord mesenchymal stem cell (hUCMSC) transplantation serves as a regenerative therapy; however, concerns regarding the viability and efficacy of transplanted cells in inflamed regions persist. Hypoxic preconditioning of hUCMSCs has emerged as a potential strategy for augmenting their regenerative and immunomodulatory capacities. This study aimed to evaluate the expression of inflammatory (tumor necrosis factor [TNF]-α) and bone regenerative biomarkers (nuclear factor of activated T-cell [NFATc1], osteocalcin, collagen type I alpha 1 [COL1α1]) within peri-implantitis models subsequent to the transplantation of hypoxia-preconditioned hUCMSCs. Peri-implantitis models were established through the insertion of implants into the femur bone of 42 Wistar strain Rattus norvegicus, followed by intrasocket injection of lipopolysaccharide. The experimental animals were categorized into three groups (control, normoxia, and hypoxia) and underwent observation on days 14 and 28. The expression levels of TNF-α, NFATc1, COL1α1, and osteocalcin were evaluated using immunohistochemical staining, and the resulting data were subjected to one-way analysis of variance analysis (p < 0.05). Transplantation of hypoxia-preconditioned hUCMSCs significantly ameliorated inflammation and osteoclastogenesis, as evidenced by significant reductions in TNF-α and NFATc1 expression compared with the control group. Furthermore, hypoxic preconditioning of hUCMSCs demonstrated a significant elevation in the expression of osteocalcin and COL1α1 relative to the control group. The transplantation of hypoxia-preconditioned hUCMSCs exhibited a capacity to ameliorate inflammation and enhance bone regenerative processes in peri-implantitis rat models.

Use of Antibacterial Envelopes in Neuromodulation Surgeries With Implantable Device Insertion: A Systematic Review and Meta-Analysis.

Neuromodulation is an advanced therapeutic intervention for managing various neurological, psychiatric, and functional disorders. However, a significant challenge is the risk of infections at the device implantation site. Previous studies have shown that antibacterial envelopes used in cardiovascular surgeries significantly reduce infection risk. It is postulated that similar benefits could occur in neurosurgeries involving implant insertion, but the literature lacks studies analyzing this efficacy. This study aimed to evaluate the effectiveness of antibacterial envelopes in reducing infection rates associated with neuromodulation implants. We systematically searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials databases up to August 2024 for clinical trials comparing the use of antibacterial impregnated envelopes in patients undergoing neuromodulation-related implant insertion. This study followed Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Statistical analyses were performed using R version 4.3.2. Risk of bias was assessed using the Risk Of Bias In Nonrandomized Studies-of Interventions tool, and the quality of evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation assessment. The study was registered in Prospective Register of Systematic Reviews. Four studies, comprising 1242 patients, were included, of whom 704 (56.7%) received antibacterial envelopes. The pooled analysis showed that the odds of infection were 77% lower in patients using the antibacterial envelope compared with the control group (odds ratios = 0.23; 95% CI = 0.10-0.51; P < .001; I2 = 2%). The use of an antibacterial envelope significantly reduces the odds of infection in patients undergoing neuromodulation-related implant insertion by 77%. These findings underscore the potential of antibacterial envelopes to improve postoperative outcomes.

In vitro Evaluation of Titanium Exfoliation during Simulated Surgical Insertion of Dental Implants

ABSTRACT Background: Titanium dental implants are widely used due to their biocompatibility and mechanical properties. However, the potential for titanium particle exfoliation during surgical insertion remains a concern, as it may affect osseointegration and peri-implant health. This study aims to evaluate the extent of titanium exfoliation during simulated surgical insertion of dental implants. Materials and Methods: A total of 30 titanium dental implants were surgically inserted into synthetic bone blocks using a standardized drilling protocol. The procedure was conducted in a controlled laboratory environment to simulate clinical conditions. Titanium particle exfoliation was assessed using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) at multiple insertion depths (0 mm, 5 mm, and 10 mm). The quantity of titanium particles was measured and analyzed statistically. Results: The SEM and EDS analyses revealed significant titanium exfoliation at each insertion depth. The mean number of titanium particles detected at 0 mm, 5 mm, and 10 mm depths were 25 ± 5, 45 ± 8, and 60 ± 10 particles per mm2, respectively. There was a statistically significant increase in particle count with increasing depth of insertion (P &lt; 0.01). Conclusion: The findings indicate that titanium exfoliation occurs during the surgical insertion of dental implants and increases with the depth of insertion. This exfoliation could potentially impact peri-implant tissue health and osseointegration. Further clinical studies are necessary to assess the long-term effects of titanium particle exfoliation on implant success.

Assessment of Tissue Changes Observed with Single-Unit Dental Implants Placed in Conjunction with Platelet-Rich Fibrin: An Evaluative Study

Abstract Background: The advent of implants has been a big milestone in the practice of dentistry, which has largely changed the face of rehabilitative dental practice. The present evaluative study assessed the tissue changes observed with single-unit dental implants placed in conjunction with platelet-rich fibrin (PRF) since there is a relative dearth of studies on this aspect in the literature. Materials and Methods: The present prospective study consisted of 12 patients with single-rooted teeth indicated for extraction for various reasons, whereas after immediate insertion of single-unit dental implants, soft and hard tissue changes were assessed at baseline and on follow-up visits of patients at 3, 6, and 9 months, respectively, and the data obtained were subjected to statistical analysis. For carrying out the statistical analysis, a paired t test was used, whereas probability values of 0.05 or less were contemplated as being statistically significant. Results: The results in terms of mean modified plaque index and mean modified bleeding index revealed statistically significant variations in follow-up visits of patients (P &lt; 0.05). Similarly, noteworthy differences were observed in terms of the mean papillary index and mean distance between the implant–bone interface (DIB) on either side on follow-up visits of patients using a paired t test (P &lt; 0.05). Conclusion: The insertion of single-unit dental implants in conjunction with PRF resulted in a significantly improved height of the interdental papilla. In addition, an appreciable difference was observed in the mean DIB with no major complications after 9 months of implant insertion.

Automatic Segmentation of the Jaws Used in Guided Insertion of Orthodontic Mini Implants to Improve Their Stability and Precision.

Background and Objectives: With the goal of identifying regions with bicortical bone and avoiding root contact, the present study proposes an innovative technique for the simulation of the insertion of mini orthodontic implants using automatic jaw segmentation. The simulation of mini implants takes place in 3D rendering visualization instead of Multi-Planar Reconstruction (MPR) sections. Materials and Methods: The procedure involves utilizing software that automatically segments the jaw, teeth, and implants, ensuring their visibility in 3D rendering images. These segmented files are utilized as study models to determine the optimum location for simulating orthodontic implants, in particular locations characterized by limited distances between the implant and the roots, as well as locations where the bicortical structures are present. Results: By using this method, we were able to simulate the insertion of mini implants in the maxilla by applying two cumulative requirements: the implant tip needs to be positioned in a bicortical area, and it needs to be situated more than 0.6 mm away from the neighboring teeth's roots along all of their axes. Additionally, it is possible to replicate the positioning of the mini implant in order to distalize the molars in the mandible while avoiding the mandibular canal and the path of molar migration. Conclusions: The utilization of automated segmentation and visualization techniques in 3D rendering enhances safety measures during the simulation and insertion of orthodontic mini implants, increasing the insertion precision and providing an advantage in the identification of bicortical structures, increasing their stability.

Patient's Perspective on Miniscrews During Orthodontic Treatment-A Systematic Review With Meta-Analysis.

During orthodontic treatment, undesirable reciprocal forces are generated during tooth movement, which explains the use of anchorage strategies to minimise their harmful effects through intra and/or extraoral appliances. Miniscrews are intraoral devices used for temporary skeletal anchorage. Miniscrews are small-sized intraoral devices used for temporary skeletal anchorage and are easy to place and remove. However, some studies refer to adverse effects such as inflammation, pain, and discomfort. This systematic review aims to synthesise the available evidence on the use of miniscrews during orthodontic treatment from the patient's perspective. The literature search was conducted using various databases MedLine through PubMed, Cochrane Library, Web of Science Core Collection, and EMBASE. A search was also carried out in the grey literature. The search terms used were "Orthodontic Anchorage Procedures," "mini-implant," "Mini Dental Implant," "Miniscrew," and "microimplant." Cochrane risk of bias tools was used to assess the quality of included studies. Patients tend to overestimate the pain inherent in this procedure. The insertion of micro implants is more accepted than the tooth extraction procedure, with less postoperative pain reported. The location, surgical technique, and type of anaesthesia used in the placement of miniscrews influence levels of discomfort. Additionally, the execution of a good surgical technique and the clinician's communication skills are factors that influence patient satisfaction and positive perception. The most frequent outcome reported is pain and discomfort, which varies depending on its location (less with mini interradicular screws than with extra-alveolar screws). Most patients are satisfied or very satisfied with this application.

CT Analysis of INBONE Use in Total Ankle Arthroplasty

Category: Ankle; Ankle Arthritis Introduction/Purpose: Osseointegration is an important determinant of clinical success following the insertion of a orthopaedic implants. The success of osseointegration is an important predictor of the long-term clinical success of many implants, especially total joint arthroplasties. Total ankle arthroplasty (TAA) is a common surgical treatment for patients with end-stage ankle osteoarthritis. Aseptic loosening is a common complication following TAA and may be related to poor osseointegration between the prosthesis and the host bone. Thus, the purpose of this study is to investigate the patterns of ingrowth and ongrowth bone formation that occur following implantation with in Inbone TAA, and the correlation of those with patient outcomes. Methods: We conducted a retrospective review of eleven patients that underwent primary (n=8) or revision (n=3) total ankle arthroplasty with a single fixed bearing stemmed total ankle implant for end stage ankle arthritis. All participants underwent surgery at a single academic medical center with one of two foot and ankle fellowship trained surgeons. Data was collected from medical charts and imaging software. Radiographic measurements were performed on both weightbearing preoperative and postoperative radiographs and non-weightbearing CT scans. The cohort was majority male (72.7%%), with mean age 62.42 (range 40.54-81.00) years, and mean radiographic follow-up of 1.95 (range 0.46-10.39) years. Of the eleven subjects, ten had preoperative cysts on the tibia and talus. Three of the subjects exhibited new cyst formation post-implantation, notably including the patient who had no preoperative cysts. Results: Following implantation, four patients underwent reoperation, but none required revision. Cyst size and location did not significantly affect reoperation rates or alignment measurements. At 2-years postoperatively, increased radiolucency at the 2nd or 4th quadrants of the tibial stem tip was correlated with more valgus tibiotalar angle (r=.960: p=.010), while increased radiolucency in the 1st quadrant of the tibial stem shaft was correlated with a more valgus tibiotalar angle (r=-.960; p=.010). Increased radiolucency at the 3rd quadrant of the tibial stem tip (r=.957: p=.011), and 1st (r=.926: p=.024) or 2nd (r=.915: p=.029) region of the tibial stem base were correlated with a more valgus coronal tibial angle. Increased radiolucency at the 2nd quadrant of the tibial stem shaft was associated with greater sagittal displacement (r=-.926, p=.024). Conclusion: Our results demonstrate that the TAA outcomes were not affected by preoperative cyst presence nor postoperative cyst presence, region, or size. There were, however, a number of radiographic alignment measurements affected by radiolucency around the implant at 1 and 2 years postoperatively. Given the rapidly expanding implementation of TAA and the relatively high revision rate following the procedure, extensive research should be conducted to determine if osseointegration affects desirable patient outcomes.

Efficacy of Photobiomodulation in the Management of Pain and Inflammation after Dental Implants: A Randomized Clinical Trial.

Background: Photobiomodulation (PBM) is a non-invasive procedure used to manage pain and inflammation. The aim of this study is to quantitatively measure pain and inflammation and to compare the proposed PBM treatment with a simulated treatment (PBM-SHAM) in patients with dental implants. Materials and Methods: A total of 62 patients were included and randomized into two groups. Group 1 (PBM) consisted of 31 patients subjected to the insertion of dental implants and a single intraoral PBM session with an EPIC X Biolase (0.5 W and 15 J/cm²) diode laser. Group II (PBM-SHAM) included 31 patients subjected to dental implants and a simulated PBM. Each patient was given a document with visual analog scales (VASs) to record pain and inflammation during the 7 days post-surgery. The patients were assessed at the end of the week to remove the sutures, to collect the VASs, and to re-evaluate the surveys. Results: Through the use of mixed effects models, it was found that the length of time after the surgery and the number of implants placed during the intervention were important variables that had an influence on pain and inflammation. Conclusions: PBM is a non-invasive and safe treatment. Postoperative pain and inflammation associated with implant surgery decreased in a similar manner over time, independently of the application of PBM. Therefore, more randomized studies are needed with a standardized methodology to adequately assess the efficacy of this therapy.

Pengaruh Pemberian Aromaterapi Lavender Terhadap Tingkat Kecemasan pada Akseptor KB Implan di Puskesmas Haurpanggung Kabupaten Malang Tahun 2024

Introduction; In 2022, the Haurpanggung Community Health Center had a coverage of 405 people (6.61%) using MKJP for implant contraception. Fear of pain during Implant insertion is a major source of anxiety for many clients and is the reason for low implant coverage. One non-pharmacological way to reduce a person's anxiety level when an implant is being installed is with lavender aromatherapy. Objective; The aim of this research was to determine the effect of giving lavender aromatherapy on anxiety levels in birth control implant acceptors. Methodology: This research uses a quasi-experiment with a pretest posttest one group design. The population in the study included 30 implant acceptors. The sample in the research used total sampling. The instruments used were HRS-A observation sheets and technical instructions for administering lavender aromatherapy. Data analysis uses paired sample test. Research Results: The anxiety of prospective contraceptive implant acceptors before being given lavender aromatherapy was 14.40 and after the intervention was 9.57. Bivariate results show a p-value of 0.000. Conclusion: There is an effect of giving lavender aromatherapy on anxiety levels in contraceptive implant acceptors. Suggestion: It is hoped that this will provide information and increase knowledge for prospective contraceptive implant recipients to use non-pharmacological management to reduce anxiety using lavender aromatherapy.

The effect of an educational video on the immediate insertion of postpartum contraceptive implants: A randomized controlled trial.

To assess the impact of an educational video on immediate postpartum contraceptive implant utilization. This was a randomized controlled study conducted in a university hospital. Postpartum women aged over 18 years were recruited and divided into two groups: the intervention group, which viewed a 7-min educational video about contraceptive implants; and the control group, which did not. We evaluated the uptake of contraceptive implants immediately and during a 12-week period postpartum, in addition to the reasons for not selecting this method. A total of 202 participants were included in the study, 101 in each group. Viewing the educational video was associated with higher immediate postpartum contraceptive implant usage (22.77% vs 10.89%; relative risk [RR] 2.09, 95% confidence interval [CI] 1.08-4.06). However, no significant difference was observed at the postpartum follow-up visit (29.9% vs 25.74%; RR 1.61, 95% CI 0.74-1.82). The primary reasons for not selecting contraceptive implants were concerns about potential side effects and discomfort associated with the insertion procedure. The inclusion of an animated educational video significantly improved immediate postpartum contraceptive implant uptake, making it a potentially viable strategy in settings with high rates of loss to follow-up. However, further research into how to address patients' fears regarding the implant is required.

DENTAL IMPLANT INSERTION – HOW TO PLAN AND PREDICT SUCCESS

For decades, implant placement protocols and implant loading protocols were addressed independently from one another. With the healing of the alveolar socket post-extraction, the implant placement protocol and the surgical technique are determining factors for selection of an appropriate implant loading protocol; these should be considered as codependent variables. The objectives of the study were to highlight factors influencing the implant placement and loading protocol. Material and methods. The retrospective study included patients presented for teeth extraction and oral rehabilitation treatment plan that included implant restorations between October 2020 and October 2022. Factors influencing implant placement and loading protocol were analyzed for each case. Representative cases were presented with details. Results. 10 clinical cases were included in the study, in which implanto-prosthetic treatment was performed using different insertion protocols. Three representative cases were presented. Conclusions. Implant insertion protocols are closely related to multiple factors, so the clinician nowadays must carefully decide the time elapsed from tooth extraction to the moment of dental implant insertion. The insertion protocol should be chosen only if the factors influencing that protocol led to the success of the implant-prosthetic treatment.
