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 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 combination of long and short titanium plates showed superior biomechanical properties for mandible reconstruction compared to a conventional single long plate. It provided higher safety, lower fixation instability, and good bone segment stability during masticatory activities. This preclinical evidence supports the feasibility of using short plates for complete mandible reconstruction and may have implications for treating other large-sized bone defects with customised implants using additive manufacturing technology.

Summary: This study utilized a 3-Dimensional finite element foot model to investigate the role of soft tissue stress in flexible flatfoot, finding that the plantar fascia plays a crucial role in maintaining the medial longitudinal arch. The equivalent stress in the arch increases with plantar fascia attenuation, indicating its importance in arch support.

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.

Summary: This study evaluated the mechanical effectiveness of tuning fork plate fixation system compared to dual iliac screw fixation through finite element analysis. The results showed that both fixation systems had similar motion reduction at spine levels, but the stress values were higher in the dual iliac screw constructs compared to the tuning fork plate fixation system. The factor of safety of the tuning fork plate device was 50% higher than the dual iliac screw fixation.

Summary: Cranial morphology in lepidosaurs varies greatly with frequent loss or reduction of bony elements, but the mechanical principles underlying these variations remain poorly understood. Through computer-based simulation, it was found that despite differences in strain gradients, the overall strain magnitude and distribution across the cranium were similar in two large, active foragers, highlighting the importance of the postorbital bar in resistance to feeding loads. The reduction of the postorbital bar did not impair biting performance or structural resistance to feeding loads in Varanus niloticus.

Summary: The study investigated the accuracy of holographic headsets in registering virtual models with real-world features based on the position and size of image markers. Results showed that certain image marker positions and smaller markers led to larger errors in perceived dimensions of virtual models, while larger markers resulted in smaller errors. Approximately 70.7% of cases had errors of <= 2 degrees, and approximately 76% had errors of <= 2 mm.

Summary: The study used computational methods to analyze the biomechanics of rabbit cranium during mastication, showing that most of the cranium, including the unique fenestrated rostrum, transmits masticatory strains. Peak strains were found to be attributed to both incisor and molar biting, indicating a skull shape adapted for a combination of infrequent incisor bites and cyclic molar bites. However, certain regions experienced low peak strain, suggesting they are not designed to resist masticatory forces.

Summary: Cranial sutures are fibrocellular joints between skull bones that are gradually replaced with bone, facilitating growth and cranial shape change. Our study used computational biomechanical methods to simulate biting in a rat skull and found that the presence of cranial sutures did not significantly alter overall strain gradients across the cranium, but did affect local variations in strain magnitudes and patterns near the sutures. This suggests that the importance of sutures differs in different regions and should be considered in models requiring accurate local strain magnitudes and patterns.
