Facial balance is an attainable goal of orthodontic treatment. If it is within the power of the orthodontist to favorably affect facial balance, doing so should be an overriding priority. The question, "What can be done to preserve or enhance facial balance, harmony, and proportion?" should be answered during diagnosis in any patient who presents for orthodontic treatment. The purpose of this paper is to offer some answers to this question when the patient has a medium to high Frankfort mandibular angle or, stated differently, a moderate to excessive anterior facial height. If facial balance is to be a reality for patients with these skeletal patterns, the following three objectives must be met during treatment: (1) The mandibular incisors must be upright or overly upright over their bony support. (2) Anterior facial height must be controlled. (3) Posterior vertical dimension must be controlled. If these three objectives are realized during active mechanotherapy of moderate- to high-angle patients, balance and harmony of the lower face should be an attainable goal.
面部平衡是正畸治疗可以实现的目标。如果正畸医生有能力对面部平衡产生积极影响，那么这样做应该是首要任务。对于任何前来接受正畸治疗的患者，在诊断过程中都应该回答“可以采取哪些措施来保持或增强面部平衡、和谐与比例？”这个问题。本文的目的是当患者具有中等至高的法兰克福下颌角，或者换句话说，具有中度至过度的前面部高度时，为这个问题提供一些答案。如果要让具有这些骨骼模式的患者实现面部平衡，那么在治疗过程中必须实现以下三个目标：（1）下颌切牙在其骨支持上必须直立或过度直立。（2）前面部高度必须得到控制。（3）后垂直维度必须得到控制。如果在中度至高度角患者的积极机械治疗过程中实现了这三个目标，那么下面部的平衡与和谐应该是一个可以实现的目标。
