一、概述: 随着电子科学的发展,电子计算机技术已进入口腔各科的研究和临床工作中,而以口腔正畸科的应用较早而多。一些口腔正畸学者认为过去的30～40年中,在口腔正畸的机械水平,矫正器械及正畸力作用于组织的局部反应研究较多,因而在矫治方法及疗效方面取得了较大的进展。但相比之下,对于矫治作用的长期生物学方面的知识,以及由内在机制引起的(牙合)力变化动力学,如遗 First, an overview: With the development of electronic science, electronic computer technology has entered the oral research and clinical work in all subjects, and Orthodontics more and more applications. Some oral orthodontic scholars believe that over the past 30 to 40 years, orthodontic mechanical level, orthodontic appliances and orthodontic force on the local response to the study more, and thus in the treatment methods and efficacy has made a larger progress. In contrast, however, the long-term biological knowledge of orthodontic action and the kinetics of change in occlusal force caused by intrinsic mechanisms,
