Removable dental prostheses for patients with Sjögren's syndrome

Sjögren's syndrome (SS) is a chronic autoimmune condition primarily affecting the salivary and lacrimal glands, leading to pronounced dry mouth (xerostomia) and dry eyes. These symptoms create unique challenges for SS patients requiring removable dental prostheses, as the lack of saliva significantly impacts the retention, comfort, and overall effectiveness of these devices. Without adequate saliva, prosthetic retention diminishes, and patients frequently experience issues such as mucosal irritation and increased susceptibility to infections. To address these issues, tailored material choices are critical in designing effective prosthetic solutions. Soft liners, moisture-retentive acrylics, and antimicrobial coatings are among the innovations improving both retention and comfort for SS patients. The aesthetic and functional outcomes of prosthetic solutions are also essential considerations. Enhanced retention mechanisms, such as implant-supported overdentures, not only improve masticatory performance but also aid in preserving the patient’s facial profile and lip support. Advanced materials offering translucency and color stability contribute to a more natural appearance, which is critical for patient satisfaction. The maintenance of these prostheses requires specific care routines to mitigate microbial buildup and tissue irritation. Specialized cleaning agents and salivary substitutes help maintain hygiene and reduce discomfort, while regular follow-up visits enable timely adjustments to accommodate tissue changes and extend the prosthesis lifespan. Implementing a comprehensive approach that considers material selection, functional and aesthetic outcomes, and maintenance strategies can greatly enhance the quality of life for SS patients. By understanding and addressing the specific needs associated with xerostomic conditions, dental professionals can provide prosthetic solutions that offer both reliability and comfort in this challenging context. Regular patient education and diligent care routines remain essential to ensure the long-term success and durability of removable dental prostheses for individuals with SS.

Effect of endodontically treated teeth on prosthetically guided orthodontics with clear aligners: a case series

BackgroundProsthetically guided orthodontics (PGO) can correct the malocclusion for better prosthetic rehabilitation in esthetic rehabilitation. Unlike conventional orthodontic treatment, only minor tooth movement is designed in PGO according to the requirement of subsequent restoration. For better appearance during the treatment, PGO is often performed with clear aligners, which have no metal brackets. It has been proven that the PGO with clear aligners can achieve generally satisfactory outcomes. However, its risk has not been fully known due to the paucity of relevant studies.Case presentationThree patients who needed esthetic rehabilitation with mild malocclusion were included in this study. After evaluation, a prosthetic solution alone was considered insufficient to provide optimal outcomes. Thus, they were treated using PGO with clear aligners (Invisalign Go, Align Technology, Santa Clara, California, USA) and accomplished prosthetic rehabilitation subsequently. Dental history and X-ray examination revealed that endodontically treated teeth (ETT) existed in all the cases. Intraoral photographs were collected to compare the pre-treatment and post-treatment dentition. After PGO, posterior ETT did not maintain their position as scheduled and lost occlusal contacts, while all the anterior teeth, including anterior ETT, were moved to the designed position. Corresponding prosthetic rehabilitation was used to solve it after consulting with the patients.ConclusionsOcclusal contact loss of posterior ETT is a potential risk in PGO with clear aligners, affecting the orthodontic result.

Isolated aseptic loosening in total knee arthroplasty: a comprehensive 10-year review of partial vs. total component revisions

BackgroundIn total knee arthroplasty (TKA), isolated aseptic loosening (IAL) requires the replacement of prosthetic components, with ongoing debate regarding the effectiveness of partial component revision (PCR) compared to total component revision (TCR). This study aims to compare implant survival and surgical outcomes between PCR and TCR in the context of IAL.MethodsThis retrospective study analyzed data from 285 patients who underwent revision TKA for IAL between January 2000 and December 2013. After applying exclusion criteria, 112 patients were included in the analysis—60 undergoing TCR and 52 undergoing PCR.ResultsPCR was associated with shorter operative times and hospital stays compared to TCR, alongside significant differences in the choice of revision prostheses. Although the prosthesis failure rates were comparable between the groups (13.6% for TCR and 18.33% for PCR), significant risk factors for failure were identified, including a canal filling ratio (CFR) below 0.8 and a discrepancy over 0.2 between CFR views. However, no significant differences in overall survivorship were observed between the groups.ConclusionsBoth PCR and TCR provide similar survival rates and clinical outcomes for managing IAL in TKA. PCR provides advantages in terms of surgical efficiency and patient recovery, while reducing the need for more constrained prosthetic solutions. The study identifies CFR as a critical predictor of prosthesis failure, highlighting the importance of detailed preoperative planning and implant selection. These findings contribute valuable insights for improving revision strategies in IAL, enhancing surgical outcomes in TKA.Level of evidenceIII.

Assessing PET composite prosthetic solutions: A step towards inclusive healthcare

The demand for affordable prostheses is particularly high in Low Middle-Income Countries (LMICs). Currently, sockets are predominantly manufactured using monolithic thermoplastic polymers, which lack durability and strength, or consumptive thermoset resin reinforcing with expensive composite fillers like carbon, glass, or Kevlar fibers. However, there exist unmet and demanding needs among amputees for procuring low-cost, high-strength, and faster socket manufacturing methods. We evaluate a socket made from a novel manufacturing technique utilizing an affordable and sustainable composite material called commingled PET (polyethylene terephthalate) yarn, along with a reusable vacuum bag, to produce custom-made sockets in a purpose-built curing oven. Our innovative fabrication methodology enables the production of complex-shaped patient sockets in under 4 h. To evaluate the efficacy and performance of the PET sockets, we conducted trials with both unilateral and bilateral amputees over a six-month period, in collaboration with Bhagwan Mahaveer Viklang Sahayata Samiti (BMVSS) in India. Utilizing a 6-min walking test, we measured various gait parameters, including ground reaction forces and flexion angle, for both unilateral and bilateral amputees.The gait analysis conducted on amputees using our PET-based sockets demonstrated their ability to engage in daily activities without interruptions, reaffirming the functional efficacy of our approach. By combining self-reinforced PET with our novel fabrication technique, we offer a unique and accessible solution that benefits clinicians and patients alike. This study represents significant progress towards achieving affordable and personalized prostheses that cater to the needs of LMICs.

Review on Amprobot an Assistive Robotic Arm for Amputee Patients

In this paper, an aim has been set to prepare a literature review based on the development and the production of robotic prosthetic arm for amputee patients. As written in 2011 census, the population with disabilities were approx. 2.68 crore, which accounts for 2.23% for the total population. In India, various companies like M/s. TTK Healthcare Limited and organizations like the Indian Institute of Technology (IIT) working on developing advanced prosthetic technologies and considerable R and D has been involved in the development and deployment of robotic arms and advanced prosthetic solutions for amputees. However, the implementation of these studies is yet to be enforced in the Indian Market to the best level. Thus, there was a huge gap between Study and its Practical usage. Research and results have been produced for many single segments explaining various factors to be considered for Robotic Arm. However, to date, very few attempts have been made to practically implement and optimize the overall design. The various different articles and their processes are studied thoroughly.

Utilizing Additive Manufacturing for Economical Prosthetic Limb Prototyping: A Guide from Regression Modelling

This study investigated the development of a low-cost prosthetic limb using additive manufacturing techniques, guided by anthropometric data and regression modeling. Anthropometric measurements were collected from 250 healthy young adults to characterize limb dimensions. Statistical analysis revealed the mean, standard deviation, and range for right and left leg and elbow lengths. A regression model was formulated to estimate limb lengths based on these measurements. A robust regression model demonstrated a significant correlation (r = 0.993, r² = 0.986) between right limb measurements and corresponding left limb measurements, indicating that right leg and elbow lengths could accurately predict left side measurements. The derived regression equation (RLL = 2.253 + 0.959 LLL + 0.054 LEL) provides a practical tool for designing customized prosthetics. Utilizing 3D printing technology, these findings can enhance the production of tailored prosthetic limbs, improving comfort and functionality for users. The study recommends further validation across diverse populations, integration into clinical practices, and continued research and development supported by policy and funding initiatives. These steps will advance the accessibility and effectiveness of personalized prosthetic solutions.

Four-mm-short implants in the rehabilitation of posterior atrophic jaws: A retrospective study on 212 patients with a mean follow-up of 8.02 years.

This study aimed to assess clinical efficacy of 4-mm-short implants in patients with posterior severe vertical bone atrophy in the medium- and long-term follow-up. Patients rehabilitated with 4-mm-short implants in the posterior atrophic jaws, with a minimum follow-up of 3 years post-loading, were included in the study. Data were collected for eligible patients, and marginal bone loss (MBL) for each implant was evaluated. The research outcomes were implant failure, MBL and complications. A total of 212 patients with 496 implants were included, resulting in a mean follow-up of 8.02 ± 2.17 years. The implant survival rate was 95.36% (95% CI: 93.12%-97.04%). More implant failures were observed in the maxilla (p = .02) and fewer failures were observed in patients undergoing more number of hygienic sessions per year (p < .001). The average MBL after 1-year-loading was 0.47 mm, increasing to 0.59 mm after 10 years; after 3 years no statistically significant increase in MBL was observed. Maxillary implants showed greater bone loss than mandibular ones (p < .001). More frequent professional oral hygiene sessions per year resulted being related with reduced MBL (p < .001). Four-mm-short implants showed high survival rates with an up to 10-year follow-up. Their use can offer a fixed prosthetic solution for patients with posterior vertical bone atrophy, minimizing surgical invasiveness, rehabilitative times and costs.

Transient characterisation and analysis of shape memory alloy wire bundles for the actuation of finger joints in prosthesis design

Most current lower arm/hand prosthesis designs incorporate relatively bulky, heavy dc motors that produce substantial noise when performing actuation which rendersthem uncomfortable for the end-user. The engineering challenge is to produce more effective powered upper limb prosthetic solutions. Identification, characterisation and testing of actuation methods with better force to weight ratios are essential pre-requisites for this. The main aim of this work is to carry out a comprehensive study to establish conclusively the feasibility of employing Shape Memory Alloys (SMA’s) in the actuation of prosthetic finger designs. A comprehensive review of existing literature has been undertaken in order to establish the maximum grip forces at each phalanx of the human hand under different loading conditions. An experiment was developed in conjunction with this review to estimate the time response of the hand during a gripping/releasing action. These results, in combination with physical dimensions, will be used to drive the design of a prosthetic limb.&#x0D; A test rig has been developed which can facilitate complete transient and steady-state characterisation of a range of SMA wire diameters and bundle configurations. Anumber of different configurations were tested, each configuration having a different combination of 150 μm and 300 μm diameter nitinol wires. A data acquisition systemwas used to capture and retain data pertaining to the full characterisation of the bundles and in particular the strain and force capabilities of the various arrangements. A direct comparison is made between the actuator capabilities and the requirements of a working limb for basic gripping actions. This work will contribute to the development of an improved powered prosthetic solution.

Maxillary sinus floor augmentation with autogenous bone graft compared with composite grafts: A one-year single-blinded randomized controlled trial.

The objective was to assess the one year implant treatment outcome and patient-related outcome measures (PROMs) following maxillary sinus floor augmentation (MSFA) with autogenous bone graft (ABG) from the zygomatic buttress (control) compared with 1:1 mixture of ABG and anorganic porcine bone mineral (APBM) (Test I) or biphasic bone graft material (BBGM) (Test II). Sixty healthy patients (34 females, 26 males) were randomly allocated to either control or test groups. Outcome measures included survival of suprastructures and implants, implant stability quotient, health status of peri-implant tissue, peri-implant marginal bone loss, frequency of complications, and PROMs using Oral Health Impact Profile-14 combined with questionnaire assessing patient perception of peri-implant soft tissue, prosthetic solution, implant function, and implant treatment outcome using visual analogue scale. Mean differences were expressed with standard deviation and 95% confidence interval. Level of significance was .05. All suprastructures and implants were well-functioning after one year of functional implant loading. There was no significant difference between control and test groups in any of the applied outcome measures. The implant stability significantly increased from implant placement to abutment connection within all groups (p < .001). High patient satisfaction and significant improvement in oral health-related quality of life was also reported within all groups. This study demonstrates that MSFA with composite grafts containing minimal amounts of ABG reveals comparable implant treatment outcomes as compared with ABG alone, after one year of functional implant loading. Extensive ABG harvesting in conjunction with MSFA therefore seems not to be needed.

Nanoparticle-based optical interfaces for retinal neuromodulation: a review.

Degeneration of photoreceptors in the retina is a leading cause of blindness, but commonly leaves the retinal ganglion cells (RGCs) and/or bipolar cells extant. Consequently, these cells are an attractive target for the invasive electrical implants colloquially known as "bionic eyes." However, after more than two decades of concerted effort, interfaces based on conventional electrical stimulation approaches have delivered limited efficacy, primarily due to the current spread in retinal tissue, which precludes high-acuity vision. The ideal prosthetic solution would be less invasive, provide single-cell resolution and an ability to differentiate between different cell types. Nanoparticle-mediated approaches can address some of these requirements, with particular attention being directed at light-sensitive nanoparticles that can be accessed via the intrinsic optics of the eye. Here we survey the available known nanoparticle-based optical transduction mechanisms that can be exploited for neuromodulation. We review the rapid progress in the field, together with outstanding challenges that must be addressed to translate these techniques to clinical practice. In particular, successful translation will likely require efficient delivery of nanoparticles to stable and precisely defined locations in the retinal tissues. Therefore, we also emphasize the current literature relating to the pharmacokinetics of nanoparticles in the eye. While considerable challenges remain to be overcome, progress to date shows great potential for nanoparticle-based interfaces to revolutionize the field of visual prostheses.

Masticatory Function in Stage IV Periodontitis Patients Treated with Fixed Prosthetic Rehabilitations: A Case Series.

The present study assessed the impact of a fixed prosthetic rehabilitation on masticatory function in patients diagnosed with stage IV periodontitis. Eligible participants were adults in need of complex rehabilitation due to masticatory dysfunction. Masticatory function was evaluated using the two-colored chewing gum mixing ability test (VOH) at the diagnostic phase (T0), 1 week after delivery of the prosthetic prototype (T1), and 1 week after delivery of the final prosthetic solution (T2). Ten subjects were treated with a fixed prosthesis following periodontal and implant surgery using an individualized, fully digital workflow. Full-mouth plaque and bleeding scores, pocket depth, and clinical attachment level improved significantly. VOH was 0.472 ± 0.168 at T0, 0.358 ± 0.166 at T1, and 0.250 ± 0.123 at T2. A significant improvement in VOH was observed from T0 to T1 (difference: -0.114; 95% CI: -0.199 to -0.029; P = .014) and from T1 to T2 (difference: -0.108; 95% CI: -0.200 to -0.015; P = .027). From T0 to T2, VOH increased by 44.3%. Self-perceived assessment of masticatory function also improved from T0 to T2 (P = .002). The fixed prosthetic rehabilitation in patients with stage IV periodontitis allowed for a significant improvement in objective and subjective measurements of masticatory function.

Oral Prosthetic Rehabilitation in Patients with Epidermolysis Bullosa Hereditaria: A Systematic Review.

To review the oral prosthetic rehabilitation of patients with epidermolysis bullosa hereditaria (EBH) and study the level of evidence and quality of the presented available articles and establish clinical recommendations for the prosthetic management of these patients. An electronic search was done in July 2022 in five databases following PICOTS elements. The quality of the reports was established using the modified Pierson, Bradford Hills, and Ottawa Newcastle scale. Data extracted from 19 case reports for protocolized analysis corresponded to 64 patients and 80 dental prostheses, with almost 9 out of 10 patients being completely edentulous. The distribution of EBH types was 84% dystrophic, 10.5% junctional, and 5.5% simplex. The difficulties encountered by the authors synthesized in this review characteristically reflected those most likely encountered in dental practice. Most rehabilitations were implant-supported prostheses (85%), followed by removable dentures (10%) and dental-supported rehabilitations (5%). Fixed full-arch implant-supported prostheses represented 76.4% of implant-supported prostheses, and this prosthetic solution reflected the highest scientific quality. For an individualized approach to treatment, we recommend that in cases of total edentulism, fixed full-arch implant-supported prostheses are the most appropriate because they allow the best computer-aided planning, design, manufacture, and fitting of the prosthesis in such a complex clinical context.

Surgical extrusion, an alternative to a dental implant?

Unfortunately, accidents do happen. Dentoalveolar injury to the front teeth resulting from trauma can sometimes be so problematic that an (adhesive) restoration seems almost impossible to make, let alone saving the tooth. In this contribution the case of a 17-year-old patient whose upper incisor suffered severe dentoalveolar trauma in a traffic accident is presented. His upper incisor was fractured deeply subgingivally, at bone level, and at first glance, appeared to be lost. Surgical extrusion, however, in this patient represents a full alternative to a prosthetic solution, such as a dental implant.
