New Trend in Treating Class II Division 2 Subdivision: A Case Report

Ashok Pothuri Sr et al. Cureus. .

Abstract

Class II correction in non-growing patients will always pose a challenge in treatment, especially in a subdivision condition where one quadrant will exhibit class II molar and canine, and the other side will exhibit class I. In such a scenario, a contemporary extraction protocol will face a challenge in symmetric space closure. This case report describes the management of class II subdivision malocclusion by the latest approach, i.e., extraction of a single premolar. At the end of the treatment, midlines were corrected and good functional class I canine relations on both sides were established.

Keywords: asymmetrical extraction; class i canine; class ii div 2 subdivision; dental midline; space closure.
