Abstract
© 2020 Trans Tech Publications Ltd, Switzerland.Dental implant failure started with a resorption on alveolar crest. Resorption occurred if the stress is greater than the strength threshold (ultimate strength). Alveolar bone applied with mechanical loads will adapt their strength by remodelling; which is apposition or destruction depends on internal stress level distributed on the bones. This research was conducted using Finite Element Method (FEM). A CBCT image of osseointegrated implant model was converted into computerized 3D finite element digital model. The model was given material properties, fixed support, and being simulated on occlusal loads of 87 N and friction loads of 29 N for 0.7 seconds. Maximum principal loads on alveolar bone of implant model was 41 MPa and still below the ultimate strength (69 MPa). Based on the stress level above, it may be concluded that alveolar bone on osseointegrated implant model did not undergo resorption on simulation of mastication loads.
