3차원 유한요소법을 이용한 치근형 임프란트 ”Protect-447 의 응력분석

  • 2

A stress analysis of Protect-447 dental implant is carried out using three dimensional finite element analysis. Three different shape of dental implants have been compared to give an optimal stress distribution to the surrounding bone under the vertical force only and vertical with lateral forces. The maximum stress analysis of three types of dental implant showed that tapered implant Protect-447 has the best properties in terms of stress distribution and maximum stress level among the three implant types. The results of this study also showed that lateral force is one of the crucial factors that is responsible for the excessive stress in the mandible-implant system.
