Orthodontic treatment of a transposed maxillary canine and first premolar in a young patient with Class III malocclusion.

Gracco A, Siviero L, Perri A, Favero L, Stellini E - Korean J Orthod (2015)

Bottom Line: After 25 months of active orthodontic treatment, the patient had a Class I molar and canine relationship on both sides, with ideal overbite and overjet values.The final panoramic radiograph showed that good root parallelism was achieved.Two-year follow-up intraoral photography showed stable results.

ABSTRACT
A 12-year-old girl was referred to our clinic for evaluation of an unaesthetic dental appearance. All permanent teeth were erupted, while the deciduous maxillary right canine was retained. Cone-beam computed tomography revealed a complete transposition of the maxillary left canine and first premolar involving both the crowns and the roots. Initial cephalometric analysis showed a skeletal Class III pattern, with a slight maxillary retrusion and a compensated proclination of the upper incisors. The patient's teeth were considered to be in the correct position; therefore, we decided to attempt treatment by correcting the transposition and using only orthodontic compensation of the skeletal Class III malocclusion. After 25 months of active orthodontic treatment, the patient had a Class I molar and canine relationship on both sides, with ideal overbite and overjet values. Her profile was improved, her lips were competent, and cephalometric evaluation showed acceptable maxillary and mandibular incisor inclinations. The final panoramic radiograph showed that good root parallelism was achieved. Two-year follow-up intraoral photography showed stable results.

Figure 13: Three-dimensional image of root placement in maxillary medullar bone.

Mentions: At the conclusion of the orthodontic treatment, a healthy periodontium was maintained; premolar root resorption had not progressed (Figure 12); the patient's profile was maintained; and intercuspidation was adequate, with molar and cuspid Class I relationships on both sides. The final CBCT results showed that displaced tooth roots were located in maxillary medullar bone without fenestrations or dehiscences (Figure 13). Our patient understands that the Class III skeletal pattern must be monitored until her growth is complete.
