Summary: The study compared the effect of different onlay preparation designs for various CAD/CAM restorative materials in terms of preserving cusps. It found that the non-retentive preparation design was more advantageous for reducing stress concentration in the tooth structure and providing better load distribution, particularly for LD restorations.

Summary: The aim of this study is to examine the effect of unilaterally more posterior placement of implants according to the all-on-four concept on stress distribution on bone, implants, and other prosthetic components using finite element analysis. The findings suggest that posteriorly placed implants can prevent bone resorption caused by high stress around the crestal bone, but may increase stress on the implants and prosthetic parts.

Summary: This study evaluated the biomechanical behavior of endodontically treated maxillary premolars restored with different lithium disilicate endocrown designs. The results showed that the stress levels were below the yield strength of the tooth structure and the flexural strength of the ceramic material, regardless of the design of the endocrown. Reducing the depth of the pulpal extension to 3 mm with the addition of an axial extension resulted in a more favorable stress distribution within the tooth-restoration interface.

Summary: This study aimed to investigate the biomechanical effects of horizontal meniscal tears and different resection strategies on a rabbit knee joint using finite element analysis. The results showed that the horizontal meniscal tears had little biomechanical impact on the rabbit knee joint, and some of the partial meniscectomy strategies also had minimal effect on joint stress. It is recommended to preserve the posterior root and the remaining peripheral edge of the meniscus during surgery for a horizontal meniscal tear.

Summary: This study evaluated the effect of periodontal splints made from different materials on stress distributions in compromised periodontal tissues and cement layers. Using a computer simulation of mastication, it was found that the use of splints effectively distributed loads and reduced stress. Splinting materials with low elastic moduli reduced stress concentration at the connectors, but increased tensile stress in the cement layer.

Summary: This study aimed to evaluate the influence of new resin-based CAD-CAM implant-supported materials on posterior crown restoration stress and strain concentrations. The finite element analysis revealed differences in stress distribution among different resin materials. The Estelite P Block material showed lower tensile and shear stresses compared to other resin-based materials.

Summary: This study established a three-dimensional foot-ankle model and investigated its suitability for analyzing foot-ankle biomechanical responses. Two personalization methods were compared, using magnetic resonance imaging (MRI) and fast optical scan data, respectively, to analyze the dynamic gait responses. The results showed good correlation with subject-specific experimental results, indicating the effectiveness of the model in analyzing subject-specific foot deformation behavior during dynamic gait loading.

Summary: Finite element analysis (FEA) is a widely used tool that has contributed to a better understanding of the spine and its behavior, as well as assisting in the design and application of spinal interbody cages (ICs). FEA allows for thorough testing of new designs before manufacturing, examining biomechanical responses and spinal fusion processes that cannot easily be experimented upon in vivo. This paper reviews the recent progress of FEA in spinal ICs over the last six years and discusses its limitations and future advancements.

Summary: The mechanical behavior of zirconia abutments and monolithic all-ceramic restorations connected to titanium implants with different internal connection designs were evaluated in this study, showing that the internal conical connection of zirconia abutments had higher mechanical performance. Furthermore, the choice of materials for chairside CAD/CAM monolithic restorations had similar effects on mechanical fracture and fatigue resistance. Stress distribution was found to be influenced by the connection design within the implant/restoration complex.
