A new design of mini-screw anchored maxillary molar distalizing device applying CAD/CAM technology

Abstract

Class II malocclusion is the most frequent treatment problem in orthodontic practice. In these cases, the increased overjet or the anterior crowding are caused by mesial migration. Especially for adult patients, extraction of premolars has been mainly chosen in the past. To avoid extraction therapy, distalization of the maxillary molars is regarded as the preferred method to create space and to establish a Class I molar relationship [1-3].
