title: Asymmetric transverse control of maxillary dentition with two midpalatal orthodontic miniscrews.
abstract: There have been several orthodontic modalities for maxillary transverse control with most addressing symmetric control. The asymmetric transverse control of maxillary dentition is challenging to orthodontists due to the lack of certain modalities and possible dental side effects. Skeletal anchorages provide biomechanics without orthodontic side effects, but reports of their utilization for transverse control of maxillary dentition are scarce. The purpose of this article is to introduce a novel method utilizing two midpalatal orthodontic miniscrews and a connecting wire system for the asymmetric transverse control of maxillary dentition. Records of two patients consecutively treated with this system are reported, and the related biomechanical considerations are presented.
