Abstract

The use of dental implantation to treat the problem of tooth loss is becoming more and more popular these days. However, implant-induced bone resorption remains to be a major concern in the prosthodontic clinics and research. It is hypothesised that the long-term response of the dental bones hosting a dental implant depends on the extent of bone remodelling. In most cases, the cortical bones surrounding the neck of the dental implant can resorb at a steady rate. This can be caused by either bacterial infection or occlusal overloading. Up until recently, the methods to predict dental bone resorption due to overload are scarce. In this paper, a quadratic remodelling formula was utilised to evaluate bone resorption due to occlusal overload. A 2D finite element method with a single unit implant in the mesial-distal section is considered in this study. The computational remodelling simulation was performed under overloading condition at 402N using the quadratic remodelling algorithm. The results are compared against clinical follow-up, and the effect of occlusal loading and its induced crestal bone loss was successfully predicted.
