Stellungskorrektur eines bukkal verlagerten oberen Eckzahns im späten Wechselgebiss mithilfe eines modifizierten Utility-Bogens: ein Fallbericht

maxillary canines and first molars are the most common ectopic teeth in young peple. Ectopic buccal eruption of maxillary canines is strongly associated with lack of space or crowding in the dental arch. This report demonstrates the management of a buccally erupted maxillary canine in an 22 an years,8-month-old boy without sufficient space. the patient chiefly had dental class II occlusion and was iun the late mixed dentition;the root development of his canines was consistent with dental age.To correct the distal occlusion and gain space in the maxillary arch for the eruption of both canines,the patient received cervical headgear.To guide the maxillary left canine into occlusion , it was surgically exposed and a modified utility arch was inserted The result of this approach proves that a custom-desogned utility arch allows the distal movement of a BUCCALLY DISPLACED CANINE, WHILE AT THE SAME TIME INCREASES THE MAXILLARY ARCH LENGTH
