Application of the “Wits” appraisal

The "Wits" appraisal is intended as a diagnostic aid to be used in conjunction with other analyses. Whereas the popularly used ANB angular reading is a simple method of measuring degree of jaw disharmony, there are many instances in which this reading is suspect. The "Wits" appraisal permits easy identification of these shortcomings and substitutes a reasonably reliable means of measuring extent of anteroposterior jaw disharmony.
