A comparative study of treatment outcomes between begg and edgewise orthodontic systems in class I cases.

Background: The purpose of this study was to compare the occlusal peer assessment rating (PAR) index in Class I patients treated by means of Begg and Edgewise methods.

Materials And Methods: The pre- and post-treatment study models of Class I patients, referred to two private clinics, treated with Begg method (n = 30) and standard Edgewise method (n = 30), were reviewed retrospectively using PAR index including dental displacements, buccal occlusion (anteroposterior, vertical and transverse), overjet, overbite and midline parameters. The changes in PAR indices were analyzed using paired t-test.
