Orthodontic indices have been used for many years to assess the severity of a patient's malocclusion and hence determine the need for treatment. Two indices--the Index of Orthodontics Treatment Need (IOTN) and the Peer Assessment Rating (PAR) Index--have recently been developed. The use of indices is likely to become more widespread in the future so that more uniformity is achieved in assessing need for treatment and its success. This article describes how the two indices are applied.
正畸指数多年来一直用于评估患者错牙合畸形的严重程度，从而确定治疗需求。最近开发了两种指数——正畸治疗需求指数（IOTN）和同行评估等级（PAR）指数。指数的使用在未来可能会更加广泛，以便在评估治疗需求及其成功率方面实现更高的一致性。本文介绍了这两种指数的应用方法。
