Abstract
Maxillomandibular analysis relates the upper and lower jaw. The anteroposterior relationship of the maxilla and mandible through both angular and linear measurements is used to assess the sagittal jaw relationship. To evaluate skeletal maxillomandibular changes in patients with class I malocclusion after extraction and non-extraction orthodontic treatment in the Solan population. Cephalometric radiographs before and after treatment of 50 orthodontic patients were used in the study. The sample was divided into 2 groups, Group I (Class I, N=25, extraction cases) and Group II (Class I, N=25, non-extraction cases). Maxillomandibular parameters (ANB, Wits Appraisal, Harvold unit length difference, plane angle AB, convexity angle and MKG angle) were measured in both groups. When comparing the two groups, significant changes were observed in the ANB angle (p=0.05), AO-BO (p=0.00), MKG angle (p=0.03) and convexity angle (p=0, 00). Conversely, Harvold (p=0.70) and AB plane angle (p=0.75) were found to be insignificant. The result of the above study indicated that bone maxillomandibular changes in ANB angle, AO-BO, MKG angle and convexity angle can be observed in patients after extraction and non-extraction orthodontic treatment.
