Summary: Finite element analysis was used to compare the effects of different implant lengths on atrophic mandibles with full-arch fixed prostheses. The study found that while longer implants generally showed better biomechanical behavior, 4 mm implants may also be a viable alternative for severely atrophic mandibles. Further research is needed to validate these findings.

Summary: The study found that the stress and fatigue generated in short implants compared to regular implants in rehabilitation with fixed full-arch implant-supported prostheses in atrophic mandibles are similar, but implants with a length of 4mm showed more discrepant values. Implants with lengths of 6mm and 8mm exhibited more favorable mechanical behavior.

Summary: This study aimed to evaluate the implant prosthesis and patient-reported outcomes of complete dentures retained by four implant-supported attachments in the maxilla over a 5-year period. Results showed a prosthesis survival rate of 85.2% and an implant survival rate of 80.6%. Prosthodontic success rate decreased over time and patient satisfaction improved significantly after implant-supported retention.

Summary: Through analyzing 13 studies, results showed that the survival rate of fixed mandibular 3-implant retained prostheses was 95.43%, with an average prosthesis survival rate of 89.66% and a mean marginal bone loss of 1.09mm. The study suggests that the implant and prosthetic survival rates of this type of prosthesis are similar to those of full-arch mandibular prostheses retained by four or more implants. Further research is needed to explore the topic.

Summary: This study aims to investigate the influence of the number and distribution of mini dental implants (MDIs) on the resistance of MDI overdentures to para-axial dislodgment. The findings suggest that increasing the number of MDIs can improve the resistance to para-axial dislodgment, and the distribution of MDIs has an impact on the resistance in certain directions.

Summary: This study investigated the mechanical influences of the implant-abutment connection type and inter-implant distance on the inter-implant bone using three-dimensional finite element analysis. The results showed that a CC implant is advantageous for maintenance of the inter-implant bone, and regardless of the connection type, the stress of the inter-implant bone increases as the inter-implant distance decreases.

Summary: Comparing implant and prosthesis survival rates between full-arch immediate prostheses supported by four hydrophilic implants with bicortical anchorage and by five or six hydrophilic implants without bicortical anchorage, it was found that there were no significant differences in survival rates, but bicortical anchorage can improve the primary stability of implants.

Summary: There is a lack of clinical and laboratory studies on occlusion in implant-supported prostheses, and scientific evidence supporting the superiority of one occlusal scheme over another is scarce. Proper load distribution and the avoidance of occlusal interferences can enhance implant longevity.

Summary: The aim of this study was to investigate the relation between load distribution and the number of implants supporting mandibular implant-supported screw-retained complete prostheses (ISCP). A 3-D finite element study was conducted with three simulated models. The results showed that the model with 6 implants had the best bone stress distribution and the stress was evenly distributed on the 6 implants. Increasing the number of implants reduced the stress on the bone and prostheses.

Summary: This paper discusses the role of the EPS matrix in biofilm growth, virulence, and implant-related infections on dental implant surfaces. EPS-enriched biofilms promote microbial accumulation, microbiological shift, cross-kingdom interaction, antimicrobial resistance, and biofilm virulence, leading to peri-implant tissue damage. However, the importance of EPS in implant-related infections and the development of matrix-targeted therapeutic strategies have been neglected. Therefore, further analysis of polymicrobial interactions within the EPS matrix and the development of EPS-targeting technologies are needed to disrupt the complex biofilm microenvironment for better translation to implant applications in the future.

Summary: This study presents a new method for coating titanium abutments with a protective diamond-like carbon (DLC) film. The results show that the DLC film deposited using a silicon interlayer and pulsed-direct current plasma-enhanced chemical vapor deposition (DC-PECVD) method demonstrates improved mechanical, tribological, and corrosion resistance properties compared to bare titanium. The DLC film is found to be equally effective as titanium in preventing bacterial growth while exhibiting good cytocompatibility with human gingival fibroblast cells.

Summary: Recent developments in musculoskeletal modeling have focused on model customization. Personalization of the spine profile may affect estimates of spinal loading and stability. This study investigates the biomechanical consequences of changes in the spinal profile and finds that personalizing the spine profile has medium to large effects on trunk muscle forces and negligible to small effects on spinal loading and stability.

Summary: Exercise therapy fails in about 25.0% of cases for individuals with rotator cuff tears, and one reason for this failure may be the inability to strengthen and balance the muscle forces that keep the humeral head in the correct position. This study developed computational musculoskeletal models to compare the net muscle force before and after exercise therapy between successfully and unsuccessfully treated patients. The study found that unsuccessfully treated patients had less inferiorly oriented net muscle forces, which may increase the risk of impingement.

Summary: This study aimed to explore the intra-foot biomechanical differences among individuals with chronic ankle instability (CAI), copers, and healthy individuals during dynamic tasks. The study found that copers and CAI individuals had smaller dorsiflexion angles and copers presented a more eversion position compared to healthy participants. Copers also had greater dorsiflexion angles in the metatarsophalangeal joint and more inversion moments in the subtalar joint during certain tasks. These findings can help in designing interventions to restore ankle joint functions in CAI individuals.
