Kwon, Moon, Shim, Ahn, Lee, Kim, Choi, and Kim: Histomorphometric evaluation of the implant designed by shape optimization technique

Abstract

Since the occlusal loading is transmitted to the surrounding bone, the success of an implant treatment is closely related to the distribution of the stress on the implant. The finite element analysis method is often used in order to produce a model for dispersion of stress. Assessment of the success of the implant is usually based on the degree of osseointegration which is a bone and implant surface interface.
Implant used in this research was designed through the method of shape optimization after the stress on implant was anaylzed by the finite element analysis method. This study was pertinently assessed by a clinical, histologic, histomorphometric analysis after the shape optimized implant was installed on beagle dog tibia.
The results are as follows
1. It clinically showed a good result without mobility and imflammatory reaction.
2. Implant was supported by dense bone and bone remodeling showed on the surrounding area of the implant
3. The average percentage of bone-implant contact was 58.1%.The percentage of bone density was 57.6%.
Having above results, shape optimized implant showed the pertinence through clinical and histologic aspects. However, to use the shape optimized implant, the further experiment is required for finding problems, improvement.
