Abstract
Biomechanical properties of a mandibular first molar with different cavity designs [traditional access cavities (TEC-I & TEC-II), ninja access cavity (NEC), conservative access cavity (CEC), truss access cavity (Tr-EC), caries-driven access cavity (Cd-EC), caries-driven truss access cavity (Cd-TrEC)] were compared using finite element (FE) analysis. Models were subjected to three different loads. The highest stress distribution was observed on the enamel surface of the Cd-EC design and the dentin surface of the TEC-II. The stress was mainly concentrated on the lingual root surfaces and in the pericervical area. Enlarging the access cavity significantly increased stress distribution on enamel and dentin.
期刊介绍:
The primary aims of Computer Methods in Biomechanics and Biomedical Engineering are to provide a means of communicating the advances being made in the areas of biomechanics and biomedical engineering and to stimulate interest in the continually emerging computer based technologies which are being applied in these multidisciplinary subjects. Computer Methods in Biomechanics and Biomedical Engineering will also provide a focus for the importance of integrating the disciplines of engineering with medical technology and clinical expertise. Such integration will have a major impact on health care in the future.
