上下颌前牙静态及动态显露量

摘要/Abstract

摘要： 前牙显露量作为前牙区重要的美学参数之一，是口腔修复及正畸治疗的重要参考。临床研究显示:休息位上颌中切牙显露量约为2~4 mm，微笑时约为8~10 mm，且随着年龄增长，上前牙的显露量逐渐减少，而下前牙显露量则逐渐增加。此外，前牙显露量还受性别和上唇长度等影响。同时，前牙显露量的喜好度没有统一标准，故在制定治疗方案时要充分考虑患者自身特点和美观要求。

Abstract: The amount of anterior tooth display, which is one of the most important esthetic parameters in anterior zone, has become a significant reference for prosthodontic and orthodontic treatment. Clinical research shows that the maxillary incisor display at rest and during smile is about 2-4 mm and 8-10 mm respectively. With the increasing age, maxillary anterior tooth display gradually decreases while mandibular anterior tooth display increases. Also, the anterior tooth display is affected by sex and lip length. Meanwhile, there is no uniform standard for the preference of anterior tooth display. Hence, it is essential to take patients’ esthetic demands and their own oral conditions into full consideration when making treatment plans.

Key words: esthetics, anterior tooth display, rest position, smile
