摘要
Abstract
Objective: To design a kind of custom-made, root-analogue implant for immediate implant placement. Propose the design requirements of the interference of the implant by finite element analysis. Methods: Design and manufacture the implant with the help of RE and 3D printing technology. Design 10 custom-made, root-analogue implants with the interference of 10, 20, 30, 40, 50, 60, 70, 80, 90, 100μm respectively. Simulate the implantation with the same extraction socket by finite element analysis. Results: Under the same condition, stress of cortical bone area is larger than cancellous bone area. With the increasing amount of interference, the greater the stress of implant-bone interface and cortical bone area reach the yield strength first. Conclusions: In the process of designing a custom-made root-analogue implant, the amount of interference of cortical and cancellous bone area should be designed differently. And the amount of interference of cortical bone area should be less than cancellous bone area's.关键词
