Two reliable and valid occlusal indices have been developed to assess treatment need (Index of Treatment Need, IOTN) and the standard of treatment (The PAR Index, Peer Assessment Rating). The IOTN assesses both dental aesthetics and dental health need. The PAR index provides a single summary score for the overall alignment and occlusion. The difference between the pre- and post-treatment scores reflects the degree of improvement and the success of orthodontic intervention and active treatment. Several practical uses of the indices are described: the estimation of treatment need in an unselected and a referred population and the assessment of the standard of treatment in the Hospital and General Dental Services. It has been suggested that the use of the occlusal indices would offer several advantages: (1) uniformity in prescribing patterns, (2) safeguards for the patient, (3) patient counselling and (4) monitoring and promoting standards.
已经开发出两种可靠且有效的咬合指数，用于评估治疗需求（治疗需求指数，IOTN）和治疗标准（PAR指数，同行评估等级）。IOTN评估牙齿美观和牙齿健康需求。PAR指数为整体排齐和咬合提供一个单一的汇总分数。治疗前后分数的差异反映了改善程度以及正畸干预和积极治疗的成功率。文中描述了这些指数的几种实际用途：在未经过挑选的人群和转诊人群中估计治疗需求，以及在医院和普通牙科服务中评估治疗标准。有人提出，使用咬合指数将带来几个优点：（1）处方模式的一致性，（2）对患者的保障，（3）患者咨询，以及（4）监测和提升标准。
