课程简介

**课程名称:** 错颌畸形生物力学与支抗 **课程概述:** 本课程将带您系统地学习错颌畸形(正畸)领域的关键知识,涵盖: 1. **错颌畸形牙齿移动:** 详细介绍牙周韧带的作用与结构,牙齿移动的理论基础,最佳矫正力,牙齿对矫正力的组织反应(压力区变化、张力区变化),牙齿移动的各个阶段,以及基于力的大小和衰减的力类型,并探讨药物对矫正力反应的影响。 2. **牙齿移动的生物力学:** 讲解牛顿定律、力的定义、阻抗中心、旋转中心、力矩的定义,以及多种牙齿移动类型,包括倾斜、直立、根移动、转矩、压入和伸长。此外,还将介绍偶力、静力平衡、作用与反作用,并应用于深覆合、双侧后牙开颌、前牙反颌的矫正,以及V型弯的应用和间隙的关闭。 3. **支抗:** 阐述支抗的定义、分类(口内/口外、上颌内/上颌间、A/B/C类),并深入探讨上颌内支抗(支抗准备、软组织支抗、游离支抗)、上颌间支抗和口外支抗。课程还将讲解支抗的适应症、确定支抗类型的考虑因素,以及加强上下颌后牙支抗和上下颌前牙支抗的技巧。最后,会介绍不同级别的支抗类型,包括最小支抗(挡板、后倾、弓丝末端固定、Toe-in/Toe-Out、后方结扎、颌间橡皮圈、唇托)、中度支抗(Nance附件、腭侧弓、舌弓)、最大/强力支抗(Chromosome弓、Transpalanance)和绝对支抗。 **课程亮点:** * 从零开始,全面覆盖正畸牙齿移动、生物力学和支抗的核心概念。 * 理论与实践相结合,讲解矫正力的原理并应用于临床病例。 * 系统性介绍各种牙齿移动类型及矫正策略。 * 深入解析支抗的分类、应用及加强方法。
