Objective: To determine the association between the anteroposterior relationship of the dental arch and the jawbase in a random sample of orthodontic patients.
Materials and Methods: 478 pretreatment lateral cephalometric radiographs and study models were evaluated. Cephalometric analysis using Dolphin software to measure the ANB angle and Wits appraisal was performed, and Angle’s classification was evaluated.
Results: The agreement of the sagittal classification of the dental arch was higher with the anteroposterior relationship of the jaw-base using ANB angle (57.7%) than with Wits appraisal (43.7%). Agreement of molar relation and both ANB and Wits was higher in Class I cases (79.5% and 84% respectively). The correlation coefficient value between ANB and Wits was 0.727. A statistical significant regression between ANB and Wits was found.
Conclusions: It is evident that the Angle classification of occlusion will not reveal the full picture of the dentofacial deformity, and the three methods of anteroposterior classification agree in only one out of every three individuals.
