Assessment of hard tissue changes after horizontal guided bone regeneration with the aid of deep learning CBCT segmentation.

To investigate the performance of a deep learning (DL) model for segmenting cone-beam computed tomography (CBCT) scans taken before and after mandibular horizontal guided bone regeneration (GBR) to evaluate hard tissue changes. The proposed SegResNet-based DL model was trained on 70 CBCT scans. It was tested on 10 pairs of pre- and post-operative CBCT scans of patients who underwent mandibular horizontal GBR. DL segmentations were compared to semi-automated (SA) segmentations of the same scans. Augmented hard tissue segmentation performance was evaluated by spatially aligning pre- and post-operative CBCT scans and subtracting preoperative segmentations obtained by DL and SA segmentations from the respective postoperative segmentations. The performance of DL compared to SA segmentation was evaluated based on the Dice similarity coefficient (DSC), intersection over the union (IoU), Hausdorff distance (HD95), and volume comparison. The mean DSC and IoU between DL and SA segmentations were 0.96 ± 0.01 and 0.92 ± 0.02 in both pre- and post-operative CBCT scans. While HD95 values between DL and SA segmentations were 0.62mm ± 0.16mm and 0.77mm ± 0.31mm for pre- and post-operative CBCTs respectively. The DSC, IoU and HD95 averaged 0.85 ± 0.08; 0.78 ± 0.07 and 0.91 ± 0.92mm for augmented hard tissue models respectively. Volumes mandible- and augmented hard tissue segmentations did not differ significantly between the DL and SA methods. The SegResNet-based DL model accurately segmented CBCT scans acquired before and after mandibular horizontal GBR. However, the training database must be further increased to increase the model's robustness. Automated DL segmentation could aid treatment planning for GBR and subsequent implant placement procedures and in evaluating hard tissue changes.

Flap vs. Flapless Implant Placement in Immediate Functional Loading: A Comparative Analysis

ABSTRACT Aim: The aim of the current study was to evaluate crestal bone loss by utilizing flapless and flap implant placement procedures. Methods: For this investigation, a total of 60 patients who met the inclusion criteria were chosen. Following selection, patients were split evenly into two study groups: flap surgery and flapless surgery for implant placement. The Kruskal-Wallis test was used for statistical analysis. The crestal bone loss was taken at baseline, 3 months, and 6 months. Result: The mean age of all study participants, who were males, was 42.53 ± 4.25 years. Statistically significant P values (P = 0.03) were attained on comparing the groups on the mesial side, while on the distal side, the results were not significant. The flapless method resulted in less bone loss. Conclusion: Compared to flap surgery, flapless implant implantation showed decreased crestal bone loss.

Anatomical Factors of the Anterior and Posterior Maxilla Affecting Immediate Implant Placement Based on Cone Beam Computed Tomography Analysis: A Narrative Review.

The aim of this narrative review was to provide insights into the influence of the morphological characteristics of the anatomical structures of the upper jaw based on cone beam computed tomography (CBCT) analysis on the immediate implant placement in this region. To conduct this research, we used many electronic databases, and the resulting papers were chosen and analyzed. From the clinical point of view, the region of the anterior maxilla is specific and can be difficult for immediate implant placement. Anatomical structures in the anterior maxilla, such as the nasopalatine canal and accessory canals, may limit and influence the implant therapy outcome. In addition to the aforementioned region, immediate implant placement in the posterior maxilla may be challenging for clinicians, especially in prosthetic-driven immediate implant placement procedures. Data presented within the recently published materials summarize the investigations performed in order to achieve more reliable indicators that may make more accurate decisions for clinicians. The possibility for immediate implant placement may be affected by the NPC shape in the anterior maxilla, while the presence of ACs may increase the incidence of immediate implant placement complications. The variations in IRS characteristics may be considered important criteria for choosing the implant properties required for successful immediate implant placement.

Current status of pre- and retropectoral breast reconstructions worldwide: a narrative review.

Advances in breast cancer research and technology contribute to conservative ablative surgical approach with emphasis on reconstruction. The introduction of biologic membranes in breast surgery facilitates a one-stage implant reconstruction while the importance of the pectoralis major muscle involvement in the procedure becomes debatable. A subsequent increase in prepectoral implant placement procedures seems to close a cycle of innovations in implant-based breast reconstructions. This sparks a debate that calls for a critical review of existing literature considering that new challenges tend to arise along with new perspectives. The authors seek to scope the present status of prepectoral and subpectoral implant reconstruction worldwide, and answer recurring questions, including the novelty of presented innovations in the context of existing literature. The article is based on a literature search in PubMed with the keywords "prepectoral" or "subpectoral" and "breast reconstruction", in addition to the authors' experience with a large number of patients. Recent studies focus on the comparative safety of prepectoral vs. subpectoral placement debating the use of biologic vs. non-biologic sheets and implant texture. There seems to be more emphasis on early post-operative safety of the procedures, rather than any long-term prospects of their comparison, up to this point. Skin and nipple sparing mastectomy (SSM/NSM) together with biological membranes have played a key role in current practice and cannot be overlooked. After reading this paper, the reader should have a firm understanding of the key elements of implant-based breast reconstruction in historical context with emphasis on muscle planes and their pros and cons.

Cone-wedge anchored surgical templates for stackable metal guide: a novel technique

ObjectiveTo address the instability in implant surgical guides, this technique proposes an alternative anchoring mechanism in the stackable metal surgical guides utilizing cone-wedge anchors for improved stability.MethodsPostoperative implant position superimposed onto the preoperatively planned design using Mimics Medical 21.0 and Materialise Magics 24.0 to assess 3D coronal implant deviation, 3D apical implant deviation, and implant angular deviation.ResultsPostoperative cone-beam computed tomography (CBCT) revealed a high level of precision in the implant placement, with an average 0.97 mm deviation at implant coronal region, 1.56 mm at implant apexes, and 2.95° angular deviation.ConclusionThis technique introduces a novel cone-wedge anchoring mechanism to enhance the stability of stackable metal surgical guide templates, addressing inherent instability issues. The utilization of this approach significantly improves the accuracy of implant placement procedures.

Immediate Implant Placement in the Aesthetic Area using Inverted Body-shift Design: A Prospective Clinical Pilot Study.

A prospective clinical pilot study was carried out to evaluate a novel macroimplant design with a 12° angled platform. The implant is placed at the center of the socket, optimizing all the alveolar bone. In addition, the prosthetic emergence should be ideal, as it is corrected and emerges through the cingulate area. Twelve patients were enrolled in an immediate implant placement procedure with immediate aesthetic rehabilitation to replace an anterior maxillary tooth, and were treated with inverted body-shift design with 12° angled neck. Only type I sockets according to the Elian classification were considered eligible for the study. There were no implant failures after one year of loading. Regarding the horizontal and vertical hard tissue changes, there was a statistically significant median overall horizontal change of -0.99 mm at 1 mm and of -0.61 mm at 3 mm. On the other hand, stability was observed at 5 mm, since the result obtained was not statistically significant. The median pink esthetic score (PES) at one year of follow-up was 11.5. This implant may be useful in the immediate tooth replacement treatment of maxillary anterior post-extraction sockets, nevertheless, comparative studies with conventional implants should be carried out.

Effect of Advanced Platelet-Rich Fibrin and Concentrated Growth Factor on Tissues Around Implants in the Maxillary Anterior Region.

Tissue repair surrounding implants is essential for the cosmetic maxillary anterior zone to respond favorably to implant therapy. Grafting platelets from an individual's blood was developed to overcome the esthetic requirements and speed up healing. Advanced platelet-rich fibrin (APRF) and concentrated growth factor (CGF) are used for good healing. Our aim was to evaluate the impact of APRF and CGF on healing of tissues around dental implants in the anterior region of the maxilla. A total of 60 patients who underwent dental implant placement procedures were included in this study. They were divided into two categories: category 1 consisted of patients who underwent dental implant placement procedures without APRF and CGF (n = 30) and category 2 consisted of patients who underwent dental implant placement procedures with APRF and CGF (n = 30). Assessment of alveolar bone height and bone density was conducted using CBCT at baseline and second, fourth, and sixth month postoperatively. The alveolar height and alveolar bone density in APRF group and CGF group patients was greater compared to control group patients at all follow-ups. APRF and CGF have a positive effect on the tissues around dental implants, promoting faster and better tissue healing around dental implants.

(PM-06) A RARE CASE OF SCROTAL URETHROCUTANEOUS FISTULA SECONDARY TO EROSION OF PENILE PROSTHESIS CONNECTOR TUBING

Abstract Objective The scrotal urethrocutaneous fistula is an uncommon pathology which can lead to serious complications, such as infections, scrotal abscesses, or even Fournier’s gangrene. We present an unusual case of scrotal urethrocutaneous fistula secondary to erosion of a penile prosthesis tubing in a patient with a history of erectile dysfunction. Case presentation A 68-year-old patient with no previous comorbidities and a history of prostate adenocarcinoma that was treated with radical prostatectomy + lymphadenectomy, without the need for subsequent adjuvant therapy. He was diagnosed with erectile dysfunction after surgery, refractory to intracavernous therapy therefore required a 3-component penile implant placement procedure performed extra-institutionally. Two years after the surgery, he consulted with our institution for scrotal pain and urine leak from the scrotum during micturition. Physical examination shows extrusion of prosthesis tubes in the scrotal area with no signs of infection or exposure of the cylinders. The patient was hospitalized for management with antibiotics and to replace the penile implant. A retrograde urethrography with contrast medium was performed during surgery. Fluoroscopy showed a fistulous pathway between the penile urethra and the scrotum. No passage of the contrast to the corpora cavernosa was seen. The urethral lesion and fistula were identified and repaired. A malleable prosthesis was used, considering the amount of scar tissue. The patient had an adequate postoperative period. A urethral catheter and a cystotomy were used for six weeks. After catheter removal, a voiding cystogram was performed, finding no fistulas. The patient was followed for 11 months with no complications. Conclusion Although scrotal urethrocutaneous fistulas are an infrequent complication after penile prosthesis implantation, a timely diagnosis is essential for conservative treatment and to avoid life-threatening complications. Financing No conflict.

The Metal in My Body: Patients' Perception and Attitude Toward Orthopedic Implants.

Metal implants are broadly used in orthopedics and traumatology to stabilize bone fragments. This study aimed to explore patients' awareness, body image, and overall experience of living with a metal implant after a fracture. A mixed methods convergent design (QUAN+QUAL) was adopted. A self-reported 30-item questionnaire was used to investigate patients' perception and apprehension of the implantation of orthopedic materials. To enlighten the quantitative findings, semi-structured interviews followed till data saturation. Quantitative and qualitative data were compared during the analysis phase. Results showed that women's and elders' acceptance of the implants was greater than that of men and younger patients even in acute cases. The sense of superiority provided by the implant was mainly reported by the elderly (adjusted odds ratio (ORadj) for increasing age: 1.06; 95% CI: 1.02-1.1; p<0.01), and the sense of inferiority was mainly reported by young men (ORadj: 6.19; 95% CI: 2.36-16.22; p<0.01). Similarly, women and elderly mostly tended to answer that the injured limb felt stronger after the implant placement, while young men tended to answer a sense of weakness with the implant (ORadj for increasing age: 1.06; 95% CI: 1.03-1.09; ORadj for male gender: 4.67; 95% CI: 1.87-11.7; p<0.01 for both regressions). Most participants (56.6%) and mainly young participants, regardless of gender, expressed the desire to get the metal implants removed (ORadj for increasing age: 0.91; 95% CI: 0.89-0.95; p<0.01). Misinformation and misconception were also found in a high percentage of the questioned patients (48.1%). Thematic analysis of the interviews revealed that none of the participants directly attributed any change in their life, self, or body image to the implants. An altered body image was not reported. The most reported experience was the restriction of movement due to the accident or the subsequent physical weakness. Despite the acceptance of the implant being great, the level of patient knowledge was fairly low. The present study highlights the importance of providing patients with information throughout their management to avoid misunderstandings. Age and gender did influence patients' perception of the implants. Personalized assessment is further needed to address body image issues after an implant placement procedure.

AN INSIGHT INTO AUGMENTED REALITY INTEGRATED IMPLANT PLACEMENTS

Dental implant is an extensively used treatment approach to replace a missing or extracted tooth. Implant placement procedure is a delicate procedure which requires extensive skills and theoretical knowledge. Augmented reality is a computer-based simulation which creates a three-dimensional image or environment. The integration of augmented reality in planning and placing of dental implants revolutionize the patient care in a clinical scenario. The introduction of augmented and virtual reality in treatment planning, teaching and simulation software’s has opened avenues for better understanding, diagnosis and treatment which leads to better patient care and outcomes. This article provides an insight into the available virtual reality tools for dental implant placements, effectiveness, challenges and the future of these tools in oral implantology.

Positional accuracy during the sequence of static computer-assisted implant surgery in three alveolar ridge morphologies: An in vitro study.

This in vitro study aimed to assess the positional accuracy during the sequence of static computer-assisted implant surgery (sCAIS) according to the anatomical characteristics of the alveolar ridge. Maxillary bone models with six single tooth gaps including clinical scenarios of healed alveolar ridge (HR), single-rooted (SRS), and three-rooted socket (TRS) morphologies were used in this study. Positional deviations during implant placement procedures were evaluated after the pilot osteotomy (PD), final osteotomy (FD), and implant placement with respect to the pre-planned implant position by using a software package. ANOVA and post hoc analyses were performed. A total of 90 implants were included in this study. Higher mean angular, crestal, and apical deviations were found after the PD and FD (3.5 ± 2.4°, 0.7 ± 0.3mm, and 1.4 ± 0.8mm versus 3.6 ±2.2°, 0.6 ± 0.3mm, and 1.2 ± 0.6mm) compared to IP (2.8 ± 1.6°, 0.7 ± 0.3mm, and 1.2 ± 0.5mm, p ≤ 0.004). Implants placed in TRS demonstrated higher mean angular, crestal, and apical deviations (4.0 ± 1.7°, 0.8 ± 0.3mm, and 1.6 ± 0.5mm) compared to implants placed in SRS (2.5 ± 1.2°, 0.7 ± 0.3mm, and 1.1 ± 0.4mm) or HR (2.0 ± 0.9°, 0.5 ± 0.3mm, and 0.8 ± 0.4mm, p < 0.001). Positional deviations during sCAIS procedures are initiated with the first implant osteotomy and persist throughout the drilling sequence. However, deviations slightly decreased after implant placement. The alveolar ridge morphology is strongly associated with positional deviations. Higher deviations were observed in three-rooted and single-rooted sockets simulating an immediate approach compared to healed sites simulating a delayed protocol.

Phase I NT-501 Ciliary Neurotrophic Factor Implant Trial for Primary Open-Angle Glaucoma: Safety, Neuroprotection, and Neuroenhancement.

To assess the safety and efficacy of a ciliary neurotrophic factor (CNTF) intraocular implant on neuroprotection and neuroenhancement in glaucoma. Open-label, prospective, phase I clinical trial. A total of 11 participants were diagnosed with primary open-angle glaucoma (POAG). One eye of each patient was assigned as the study (implant) eye. The study eye was implanted with a high-dose CNTF-secreting NT-501 implant, whereas the other eye served as a control. All patients were followed up for 18 months. Analysis was limited to descriptive statistics. Primary outcome was safety through 18 months after implantation assessed by serial eye examinations, structural and functional testing, and adverse events (AEs) recording. Parameters measured included visual acuity (VA), Humphrey visual field (HVF), pattern electroretinogram, scanning laser polarimetry with variable corneal compensation (GDx VCC), and OCT. These parameters were also used for secondary analysis of efficacy outcome. All NT-501 implants were well tolerated with no serious AEs associated with the implant. The majority of AEs were related to the implant placement procedure and were resolved by 12 weeks after surgery. Foreign-body sensation was the most commonly reported AE and was self-limited to the postoperative period. The most common implant-related AE was pupil miosis; no patients underwent explant. Visual acuity and contrast sensitivity decreased more in fellow eyes than in study eyes (VA,-5.82 vs.-0.82 letters; and contrast sensitivity,-1.82 vs.-0.37 letters, for fellow vs. study eyes, respectively). The median HVF visual field index and mean deviation measurements worsened (decreased) in fellow eyes (-13.0%,-3.9 dB) and improved (increased) in study eyes (2.7%, 1.2 dB). Implanted eyes showed an increase in retinal nerve fiber layer thickness measured by OCT and by GDx VCC (OCT, 2.66 μm vs. 10.16 μm; and GDx VCC, 1.58μmvs. 8.36μm in fellow vs. study eyes, respectively). The NT-501 CNTF implant was safe and well tolerated in eyes with POAG. Eyes with the implant demonstrated both structural and functional improvements suggesting biological activity, supporting the premise for a randomized phase II clinical trial of single and dual NT-501 CNTF implants in patients with POAG, which is now underway.

Minimally invasive flapless approach in dental implant – A review

Dental implants are surgically placed into or on top of the jawbone of the patients. They are considered to be an important contribution to dentistry as they have revolutionized the way by which missing teeth are replaced with a high success rate. Before dental implants, dentures and bridges were used, but dental implants have become a very popular solution due to the high success rate and predictability of the procedure, as well as its relatively few complications. A full thickness mucoperiosteal flap is used in a typical dental implant placement procedure to expose the alveolar ridge. Dental implants are then inserted in the bone, and the flaps are adapted using sutures. Over the past three decades there have been several alterations to this flap design, now integrating esthetic considerations in the critical esthetic zones of the dentition. Flapless implant surgery is one of these alterations that is quickly rising in popularity. This review will highlight about the techniques, advantages and disadvantages of flapless implant surgery over the traditional implant surgery.

Maxillary sinus surgery with autologous or allogenic graft with platelet-rich plasma/fibrin for dental implants: a systematic review

Introduction: In the context of bone grafts and regenerative processes, the maxillary sinus acts in the equalization of barometric pressures in the nasal cavity, which is lined by a membrane called Schneider's membrane. When grafting procedures are needed, our focus is often on the type of biomaterial to be used, and the success and predictability of our results do not depend only on the biomaterial. Objective: It was to perform a systematic review of the main clinical approaches of maxillary sinus surgery with autologous and/or allogeneic graft, using platelet-rich plasma or fibrin. Methods: The systematic review rules of the PRISMA Platform were followed. The search was carried out from December 2022 to January 2023 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases, using articles from 2005 to 2022. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 125 articles were found, 55 articles were evaluated in full and 27 were included and developed in this systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 25 studies with a high risk of bias and 20 studies that did not meet GRADE. It can be concluded from the present study that there is no statistical superiority observed between platelet-rich plasma, PerioGlas, or Bio-Oss in terms of their use as a grafting material along with the immediate implant placement procedure. Furthermore, the combination of autograft/xenograft and plasma rich in growth factors in the periosteal pocket flap technique is a simpler, cheaper, and faster technique than the guide bone regeneration technique to achieve moderate lateral bone augmentation in implant treatment. Tricalcium β-phosphate is a promising biomaterial for clinical situations that require bone augmentation. However, the addition of platelet-rich plasma results in decreased bone loss around dental implants.

Complication Management in Periodontal Ligament-Mediated Implant Placement with Total Extraction of the Root: A Case Report with 4 Years Follow-up

An increasing number of studies report on periodontal ligament-mediated implant placement procedures to mitigate the biological sequel of total tooth extraction in the esthetic zone. Longitudinal results of these techniques show promising results for ridge dimensional stability achieved by partial extraction of the root followed by immediate implant placement. Nonetheless, because of the recency of these techniques, there is a dearth of clinical documentation of related complications and protocols for their management. In this case report, we present the management of a complication in an implant in the aesthetic zone utilizing the “root-membrane” technique with a four-year followup. Total extraction of the root membrane and guided bone regeneration resolved the dental-related complication

Dynamic Navigation: A Novel Tool for Dental Implant Surgery

Dynamic navigation is an advanced technology that has revolutionized dental implant surgeries. Before being used in implant dentistry, navigation technique has been practiced in neurosurgery for performing minimally invasive brain surgeries. Navigation surgery for implant placement can be broadly categorized as dynamic and static navigation. The static navigation uses a static surgical guide for the sequential drilling of the osteotomy site and the implant placement. The static navigation can either be fully guided or partial/half-guided. Dynamic navigation is a computer-assisted implant placement technique that uses real-time imaging to guide the implant placement procedure. In dynamic navigation, three-dimensional (3D) software monitors and tracks the bone drilling and implant placement in real-time during the entire procedure. This technique involves prosthetically driven virtual implant placement planning with Cone Beam Computed Tomography (CBCT) before the implant surgery. The 3D image of the patient is analyzed in a CBCT scan. This image is then used to plan the placement of the implant and create a surgical guide. A resin guided template is 3D printed or milled which is used during the surgery. The CBCT scan images are transferred into a 3D virtual image using digital software, which allows 3D viewing of the structures using Computer Aided Design (CAD). A calibrated special navigation instrument with specific software guides the bone drilling sequence and the implant placement. The drilling procedure is completely tracked and the patient’s anatomy and the surgical procedures in real time is shown in a 3D software. The use of real-time imaging and computer-aided technology ensures that the implant is placed precisely in the desired location, reducing the risks associated with conventional implant placement. Dynamic navigation is an effective and precise method that allows for more accurate placement of dental implants, which reduces the chance of damaging anatomical structures. It also gives clinicians the possibility to modify the planned surgical approach during the surgery. Additionally, because the implant is placed more accurately, there is less risk of implant failure. However, a learning curve and a training period are required before one masters this novel technology. Dynamic navigation can potentially become a preferred method for dental implant placement in the near future.

Bone height and width evaluation before dental implant placement on panoramic radiographs: a scoping review

Objectives: The aim of this study is to evaluate the bone height and its width on panoramic radiography prior to dental implant placement.&#x0D; Review: This study was carried out using scoping review methods. The referenced articles were published between 2010-2021 in English or Indonesian. The search was performed using PubMed and PMC database with keywords “(((Evaluation) AND (Presurgical)) AND (Dental Implant)) AND (Radiograph)) AND (Panoramic)” and Science Direct with keywords "presurgical evaluation dental implant in panoramic radiograph". Preferred Reporting Items for Systematic Review and Meta-analysis Scoping Review (PRISMA-Scr) was utilized to perform the article finding process. It is found that the height of alveolar bone after being assessed by panoramic radiograph is between 7.95-23.42 mm while the alveolar bone width is between 7.04-10.41 mm.&#x0D; Conclusion: Panoramic radiograph can be performed to evaluate bone height and width before the dental implant placement procedure.

A Comparative Clinical Evaluation of Effectiveness of Platelet-Rich Plasma, Synthetic Allograft, and Bioresorbable Xenograft During Immediate Implant Placement.

The use of an appropriate graft material helps in an adequate amount of osseointegration. The objective of this study was to compare the efficacy of platelet-rich plasma (PRP), a synthetic allograft (PerioGlas), and Bio-Oss, a bioresorbable xenograft in immediate implant procedures. In this randomized, prospective study, 90 patients were categorized into three groups with 30 samples in each asGroup A:patients who received PRP with an immediate implant; Group B: immediate implants with synthetic allograft (PerioGlas); and Group C: patients with immediate implants placed using bioresorbable xenograft (Bio-Oss). Postoperative follow-up was done based on plaque and gingival index, measurement of probing depths, and resorption of bone. Obtained data were statistically analyzed using the "one-way analysis of variance (ANOVA)" test. Inter-group statistical comparisons between gingival and plaque indices at three, six, and 12 months of follow-up in the study groups demonstrated no statistical significance (p > 0.05). The mean probing depths and resorption of bone at three, six, and 12 months of follow-up were statistically nonsignificant (p > 0.05) on the inter-group comparison. It could be concluded from the present study that there is no statistical superiority observed among PRP, PerioGlas, or Bio-Oss in terms of their usage as a graft material along with immediate implant placement procedure.

Dynamic Navigation for Dental Implant Placement.

In modern implantology, the application of surgical navigation systems is becoming increasingly important. In addition to static surgical navigation methods, a guide-independent dynamic navigation implant placement procedure is becoming more widespread. The procedure is based on computer-guided dental implant placement utilizing optical control. This work aims to demonstrate the technical steps of a new dynamic computer-aided implant surgery (DCAIS)system (design, calibration, surgery) and check the accuracy of the results. Based on cone-beam computed tomography (CBCT) scans, the exact positions of implants are determined with dedicated software. The first step of the operation is the calibration of the navigation system, which can be performed in two ways: 1) based on CBCT images taken with a marker or 2) based on CBCT images without markers. Implants are inserted with the aid of real-time navigation according to the preoperative plans. The accuracy of the interventions can be evaluated based on postoperative CBCT images. The preoperative images containing the planned positions of the implants and postoperative CBCT images were compared based on the angulation (degree), platform, and apical deviation (mm) of the implants. To evaluate the data, we calculated the standard deviation (SD), mean, and standard error of the mean (SEM) of deviations within planned and performed implant positions. Differences between the two calibration methods were compared based on this data. Based on the interventions performed so far, the use of DCAIS allows for high-precision implant placement. A calibration system that does not require labeled CBCT recording allows for surgical intervention with similar accuracy as a system that uses labeling. The accuracy of the intervention can be improved by training.
