课程名称：横向和矢状面正畸治疗 课程概述： 本课程将带您从零基础掌握以下正畸主题：横向差异与矢状差异的治疗。课程内容主要涵盖以下几个方面： 一、横向差异 1. 交叉咬合的发展与分类 2. 后牙交叉咬合的病因 - 遗传因素 - 习惯（如张口呼吸、吸吮手指、婴儿吞咽、舌位异常） - 干扰和咬合因素（如创伤等） 3. 后牙交叉咬合的类型及诊断 - 功能性、牙槽性、骨骼交叉咬合 4. 后牙交叉咬合的矫正影响因素及治疗时机 5. 分离术的效果、适应症与禁忌症 6. 后牙交叉咬合的治疗方法 二、矢状差异 1. 矢状问题的发展与诊断 2. 二类错牙合 - 临床检查与功能评估 - 形态特征 - 治疗规划（包括固定与可拆卸的远端器具及非拔牙治疗） 3. 三类错牙合 - 治疗问题和前牙交叉咬合的评估与治疗方法（包括拔牙与面具治疗） - 矫形外科治疗适应症 通过本课程，您将能够深入理解和应用横向及矢状面正畸治疗的关键概念和技巧，提升您的正畸治疗能力。
