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 4: Three-dimensional reconstruction of the maxilla, with transposition of the left canine and first premolar.

Mentions: Cone-beam computed tomography (CBCT) examination revealed a complete transposition of the maxillary left canine and first premolar, close contact between the roots of the left canine and first premolar, and resorption of the distal root surface of the left first premolar (Figures 3 and 4). Skeletal analysis showed a Class III malocclusion with increased vertical height. The upper incisors were proclined and the lower incisors were retroclined (Table 1). Soft tissue cephalometric analy showed a dolichofacial pattern with a harmonic profile at rest; the nasolabial angle was within the reference range and the labiomental angle appeared slightly increased.
