The deviation and misalignment of teeth and jaw can lead to Angle’s Class I malocclusion (division 3 and 4 according to Anderson) and Angle’s Class III malocclusion. It causes anterior or posterior cross bite with a relatively high proportion. The proportion of patients with Angle’s Class I malocclusion (division 3 and 4 according to Anderson) and Angle’s Class III malocclusion due to the combination of maxillary laterally deficiency and mandibular prognathism varies in races and residential areas. |
