摘要

后牙脱落对颞下颌关节（TMJ）的影响一直存在争议。现有研究主要依靠临床观察，缺乏生物力学研究。本研究招募10名健康志愿者（对照组）和20名后牙脱落患者（PTL组）。重建三维颌面模型。有限元分析结果显示，PTL组的应力集中，应力幅度远高于对照组，尤其在缺牙侧。后牙脱落导致颞下颌关节不对称应力和更高的应力水平，与颞下颌紊乱的症状有关。

The impact of posterior tooth loss on the biomechanics of the temporomandibular joints.

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.
