ABSTRACT

Transposition is a unique and extreme form of ectopic eruption where a tooth develops and erupts in a position,normally occupied by an adjacent tooth. Generally, three treatment options are available when the maxillary canine and first premolar are transposed. In the first treatment option, the transposed position of the teeth can be maintained such that the first premolaris moved to the position of the canine. Second, extraction of the maxillary first premolar can be considered. Third, the position of the transposed teeth can be corrected such that their normal positions in the arch arerestored. Factors that should be considered in treatment modality decision include function, occlusion, periodontalsupport, treatment time, patient cooperation, and esthetic demands. This report describes cases of maxillarycanine-premolar transposition treated with each of the three aforementioned treatment options. In the first case,transposed teeth were arranged in their transposed position. The second case was an extraction case. In thethird case, orthodontic treatment and surgical repositioning were conducted.
