Shape Optimization of Dental Restorations

Shape Optimization of Dental Restorations

This is an interdisciplinary project involving engineers and dental scientists. Excessively high stresses at the interface between tissues and restorations are thought to be one of the main causes of restoration failure, such as deterioration at the restoration margins and bone resorption around dental implants. We propose to use engineering tools in the form of finite element simulation, shape optimization and acoustic emission to improve designs of dental restorations, and to perform clinically relevant, in-vitro mechanical tests to validate the approach. The aim is to provide the much needed experimental evidence to demonstrate that numerical simulation and structural optimization could play an important role in dental treatment planning.
