Comparıson Of Wıts Appraısal Wıth Anb Angle
Abstract
The aim of this study was to compare Wits Appraisal with ANB measurements which are used to evaluate maxillomandibular sagittal relationships. 54 measurements have been made on 203 lateral cephalograms of untreated adults and z scores of ANB and Wits measurements have been calculated in order to make them comparable. After subtraction of z scores of the combinations; four groups were established according to the differences between them. (-∞ <Z<-1) was considered as group I; (-1<Z<0) as group II; (0<Z<1) as group III; (1<Z<∞) as group IV. After this; all measurements have been evaluated by Variance Analysis and Duncan Test. By the interpretation of these differences it has been concluded that both the ANB angle and the Wits appraisal are prone to vertical differences in craniofacial morphology.
