**课程总结：II类错颌畸形的早期阻断与管理** 本课程聚焦于Orthodontic Treatment（牙套治疗）领域，重点讲解了II类错颌畸形的早期干预与管理策略。课程将深入探讨自20世纪初以来，可摘卸功能性矫治器在Orthodontic Treatment中的重要作用。 **核心内容：** * **功能性矫治器的机制：** 课程将阐述功能性矫治器如何通过牵拉肌肉和软组织，改变下颌骨的姿势，进而影响下颌的生长发育，并通过神经肌肉环境的改变促进骨重塑。 * **功能性矫治器效果的争议：** 课程会回顾大量关于功能性矫治器对下颌骨生长影响的研究，包括动物实验和人体临床试验。其中，动物实验显示功能性矫治器能增加髁突软骨细胞增殖和关节窝前缘的骨重塑，但其对人体的适用性存在争议。人体临床试验则表明，功能性矫治器能够带来轻微但显著的下颌骨生长增加。 * **功能性矫治器的适用性：** 课程将分析功能性矫治器最适合的病例类型，包括： * 11毫米以内的覆牙合（Overjet） * 深覆合（Increased Overbite） * 面部活跃生长阶段 * 患者配合度良好 * **治疗效果的多重性：** 课程将讨论功能性矫治器的多方面治疗效果，包括： * 增加下颌骨长度（通过髁突生长） * 改变门牙倾斜度 * 髁突移位 * 增加垂直向维度以纠正矢状向不调。 * **诊断与治疗技术：** 课程将教授如何诊断II类错颌畸形，并识别和管理不同类型的II类错颌畸形。内容将特别涵盖头帽（Headgear）和功能性矫治器（Functional Appliances）的应用，尤其会重点介绍Twin Block矫治器。 **学习目标：** 完成本课程后，学员将能够： * 准确诊断II类错颌畸形。 * 识别和管理不同类型的II类错颌畸形。 * 熟练运用头帽和功能性矫治器（特别是Twin Block矫治器）进行治疗。 本课程旨在为学员提供关于II类错颌畸形早期干预和功能性矫治器治疗的全面知识与实践技能。
Since the early 20th century, removable functional appliances were considered a signifi-cant part of orthodontic treatment. These appliances target the growth of the mandible and alter its posture to produce forces by stretching the muscles and soft tissues. Thisbrings out a change in the neuromuscular environment, thereby leading to bone remodeling and growth modification. However, the amount of change produced by them is still controversial. Many studies have been conducted in the past to evaluate the effects of these appliances on the growth of the mandible. Animal studies have shown that these functional appliances increase the proliferation of cells within condylar cartilage and cause bone remodeling atthe anterior border of the glenoid fossa. However, the applicability of animal studies on humans is debatable due to the differences in the duration of growth, morphology, and physiology. In the past two decades, several clinical trials done on humans claim that functional appliance therapyresults in a small but significant increase in the growth of the mandible. Literature has also shown that these appliances are most successful in cases with an overjet of up to 11 mm, increased overbite, active facial growth, and good cooperation. Some authors believe that these appliances increase the length of the mandible due to the growth of ramus, and others believe that they only cause repositioning of the teeth. In addition, to increase the length of themandible and incorporate change in the inclination of incisors, relocation of the condyle and increase in the vertical dimension to correct sagittal discrepancy should not be ignored as treatment effects. In this course, you will learn to diagnose Class II malocclusion and able to identify and manage different types of class II malocclusion with help of headgear and functional appliances specially twinblock appliance
