Abstract

The impact of posterior tooth loss on the temporomandibular joint (TMJ) is controversial. Existing studies mainly rely on clinical observation, lacking biomechanical research. This study recruited 10 healthy volunteers (Control group) and 20 patients with posterior tooth loss (PTL group). Three-dimensional maxillofacial models were reconstructed. Finite element analysis showed stress concentration in the PTL group, with stress magnitudes much higher than the Control group, especially on the tooth-missing side. Posterior tooth loss causes asymmetric TMJ stress and higher stress levels, related to symptoms of temporomandibular disorders.

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.
