唇部形态影响因素及其与正畸治疗相关性的研究进展

doi:10.13591/j.cnki.kqyx.2024.08.014

Abstract

Abstract:

The lip plays a crucial role in facial aesthetics, making them a focal point of interest for orthodontists and patients throughout orthodontic treatment due to their three-dimensional changes in morphology and position. The degree of improvement in lip morphology significantly impacts post-treatment satisfaction among orthodontic patients. Therefore, understanding the influencing factors of lip morphology and its correlation with orthodontic interventions enables orthodontists to predict post-treatment changes in lip morphology more accurately, facilitating the customization of orthodontic treatment plans. In this paper, we reviewed the progress of methods for evaluating lip morphology and its influencing factors in order to provide reference for clinical practice.

Key words: lip morphology, three-dimensional imaging technology, craniofacial morphology, tooth movement
