INFLUENCE OF CANCELLOUS BONE RIGIDITY ON STRESS DISTRIBUTION IN BONE AROUND DENTAL IMPLANT: A FINITE ELEMENT STUDY
Journal Title: Journal of International Dental and Medical Research - Year 2010, Vol 3, Issue 1
Abstract
Using the finite element method (FEM), this study sought to investigate how the Young’s modulus of cancellous jaw bones influenced stress distribution in bone surrounding a dental implant. Six models of bone with osseointegrated dental implant, with different modulus of elasticity values of cancellous bone, were used. The stress values of the six models loaded with vertical force were analyzed. The results have shown that the cancellous bone rigidity has a great effect on the stress distribution. Highly rigid cancellous bone results in even stress distribution and reduction in maximum equivalent stress. The influence of bone rigidity may extend even to cortical bone.
