Young adult patient with two palatally maxillary impacted canines and forced traction on rigid arches of stabilization. Case report

Objective. Young adult patient treated for impaction of two maxillary canines. Methods. C.S., 15 years, female. Diagnostic evaluation by clinical and radiographic examinations shows permanent den- tition with persistence of 5.3 and 6.3, impaction of 1.3 and 2.3, dento-skeletal Cl I malocclusion, normodivergence of bone bases. Analysis of TC dentalscan confirms the palatal impaction of 1.3 and 2.3. The treatment plan provided an ortho- dontic-surgical approach for adequate space management in dental arch, evaluation of eruption movements, choice of anchorage device, surgical exposure and application of the brackets. Results. Deciduous canines have been extracted and an edgewise appliance with rigid rectangular full thickness arch- wires has been used to align the arches and to obtain maximum anchorage during the forced traction. The surgical phase, for exposure of 1.3 and 2.3 respectively, performed an open technique by excisional uncovering and a close technique by a repositioned flap. The case has been finalized for the achievement of the right occlusal keys. Conclusion. The possibility to choose the surgical technique depending on the intraosseous position of impacted teeth in association to the edgewise therapy with full thickness arches allows to realize an effectiveness surgical-orthodontic approach for the forced traction of impacted teeth in a favourable position.
