Biomechanical influence of biomaterials on stress and strain distribution over implant-mandibular interaction A 3-D finite element analysis with statistical test

Rehabilitation of failed teeth by implants in mandible is one of the most accepted techniques for manipulating dental health problems. This study aimed to evaluate the stress distribution in single implant-supported prostheses placed over short implants and with different biomaterials as the stress was transmitted to the bone tissue. One of the most important results of implanting metallic screws on bone is stress shielding effect (SSE); SSE can influence osteointegration and later result in implant loosening. In current study, three most common biometallic alloys is considered to synthesize if it can predict any difference on stress and strain distribution based on different mechanical properties over interaction with mandibular bone. Here, mandibular bone modeled based on CT images which then imported to SOLIDWORKES to be modified and then analyzed using ABAQUS. Results show using titanium alloy result in decreased stress and increased strain (P < 0.05) which means more osteointegration with interacted mandibular bone can be achieved.
