Abstract

Abstract

The goals of orthodontic treatment are balance, stability and aesthetics, an important physiological foundation for achieving the above goals is a good occlusal relationship, which includes static and dynamic occlusion. The evaluation of occlusal efficacy involves the static occlusal indicators such as overbite, overjet, midline and molar relationship at the intercuspal position （ICP）, as well as the dynamic occlusion during the centric and non-centric excursions. The PAR index represents the degree of deviation from the ideal occlusion, and the occlusal alternations can be quantitatively evaluated by comparing the differences in PAR index before and after orthodontic treatment. The T-scan digital occlusal system can be used to evaluate the dynamic occlusion because of its characteristics of “force and time” correlation. In this paper, the advantages of PAR index combined with T-SCAN occlusal system in evaluating the occlusal efficacy of orthodontic treatment were reviewed.
