An FEA Analysis of Nano-Silica Reinforced Chitosan Based Dental Implant Under Dynamic Loading

This study investigates the impact of different materials and dental implant-abutment interface models on bone shielding effects, micro-gap formation, and torque loss in abutment screws. Von-Misses stress analysis identifies the MTC model as exhibiting maximum stress transfer for titanium alloy and CFR-PEEK, while the IHC model dominates for C2 bio-composite dental implants. Although material type has minimal influence on stress shielding, the implant-abutment interface model proves crucial. Micro-gap analysis reveals the Optimized dental implant consistently displaying minimal micro-gaps across materials, while the NLD model consistently exhibits maximum micro-gaps. Both material type and interface model significantly influence micro-gap formation. Torque loss in abutment screws varies, with the MTC model consistently experiencing high torque loss and IHC showing minimal loss. The study underscores the importance of considering material properties and interface models in dental implant design, offering valuable insights for the development of reliable dental prosthetics.
