摘 要
口腔正畸治疗对颌面部形态的影响研究旨在探讨正畸治疗在改善患者牙齿排列的同时，对颌面部软硬组织形态产生的影响。随着口腔医学的发展，人们对于口腔正畸的要求不仅局限于牙齿的整齐美观，更关注其对面部整体协调性的作用。本研究以不同年龄段、性别且具有不同程度错颌畸形的患者为对象，采用三维数字化成像技术与传统头影测量方法相结合的方式，在正畸治疗前、中、后三个阶段进行数据采集，通过对比分析得出结论。结果显示，正畸治疗能够有效改善上下颌骨的位置关系，使咬合功能趋于正常，同时对唇部、颏部等软组织轮廓产生积极影响，如唇部突度减小、颏部形态更加自然等。创新之处在于将三维数字化成像技术应用于整个研究过程，提高了测量精度与结果可靠性，为临床医生制定个性化正畸方案提供更为科学准确的依据，有助于实现更好的美学效果和功能恢复，推动了口腔正畸学向着精准化、个性化的方向发展。

Abstract
The study on the impact of orthodontic treatment on facial morphology aims to investigate the effects of orthodontic treatment on the soft and hard tissue structures of the face while improving dental alignment. With the advancement of oral medicine, the demand for orthodontics extends beyond mere dental aesthetics, focusing more on overall facial harmony. This research involves patients of different age groups, genders, and varying degrees of malocclusion. By integrating three-dimensional digital imaging technology with traditional cephalometric analysis, data were collected at three stages: pre-treatment, during treatment, and post-treatment. Comparative analysis revealed that orthodontic treatment effectively improves the positional relationship between the maxilla and mandible, normalizes occlusal function, and positively influences soft tissue contours such as reducing labial protrusion and enhancing a more natural chin shape. The innovation lies in the application of three-dimensional digital imaging throughout the study, which enhances measurement accuracy and reliability, providing clinicians with more scientific and precise evidence for personalized orthodontic planning. This contributes to achieving better aesthetic outcomes and functional recovery, promoting the development of orthodontics towards greater precision and personalization.
