The evaluation of implant supported bridge application at fully edentulous mandible with the use of 3D FEA

Abstract

Finite Element Analysis (FEA) that has been used commonly during last decades has in order to investigate the mechanical interference between implant–mandible and implant–soft tissue. In this study, we aimed to investigate the forces, in a type-4 bone structured 10 implant supported fixed mandible restoration with the use of FEA, that effects during functional movements of jaw. However, during the functional movements of mandible 800 N force was applied to analyze elastic and plastic deformations which have observed on xy -plane of type-4 bone structured 10 implant fixed mandible restoration's lower second molar region. According to all these investigations, as with natural tooth restorations, having plastic deformations on xy -axis posterior tooth region and yz -axis anterior tooth region at implant supported restorations explain us that natural tooth show parallel mechanical behaviors with implant supported restorations. Due to these reasons, we should be careful on crown–tooth root ratio, occlusal arrangements and buccolingual teeth diameter forming at implant supported restorations.
