Abstract: Effective biomechanical research methods can help researchers better understand the biomechanical properties of various tissues in the oral cavity，and further explore the stress distribution characteristics of various tissues under different loads，so as to help researchers evaluate the expected effects of different treatment plans and help optimize treatment regimens in order to obtain a better clinical treatment effect. At present，the commonly used research methods include electrical measurement method，photoelastic stress analysis method，finite element analysis method，etc. Different methods have their own advantages and scope of application. This paper summarizes the progress of biomechanical research methods in the field of stomatology.

Key words: biomechanics, stress distribution, oral medicine

摘要： 有效的生物力学研究方法能帮助医生更好地了解口腔内各组织的生物力学特性，并进一步探究不同载荷下各组织的应力分布特征，从而帮助医生评估不同治疗方案预期效果，帮助优化治疗方案，以期获得更好的临床治疗效果。目前常用的研究方法有电测法、光弹应力分析法、有限元分析法等，不同方法有各自的优势与适用范围。文章就生物力学研究方法在口腔医学领域中的进展做一综述。
