Abstract:
Objective To investigate the reliability and validity of three reference planes used in Wits appraisal measurement in evaluation of sagittal jaw relationship. Methods Lateral cephalo-radiography was performed before and after treatment in 25 patients with class Ⅱ division 1 of four premolars extraction. Wits appraisals were measured using the functional occlusal plane(FOP), bisected occlusal plane(BOP), and maxillary-mandibular bisector (MMB), respectively. The effect of different reference planes on Wits appraisals was analyzed. Results FOP and BOP showed a statistically significant change in their cant after treatment(P0.05). MMB Wits had the highest correlation with ANB angle (r=0.79, P
