Abstract

Proper treatment of an impacted tooth is required as it causes functional and esthetic disharmony, as well as it can cause root absorption of adjacent teeth. Treatment options for impacted teeth include periodic observation, surgical exposure, orthodontic traction followed by surgical exposure, tooth transplantation, and extraction. Modified Nance appliance, used for orthodontic traction, is clinically useful because it does not require patient cooperation. Through orthodontic traction combined with surgical exposure of impacted maxillary incisors, canines, and molars using modified Nance appliance, adequate results can be obtained.

매복치는 기능적, 심미적 장애 뿐 아니라 인접치의 치근흡수 등의 문제를 유발할 수 있으므로 적절한 처치가 필요하다. 매복치의 치료 방법으로는 주기적 관찰, 외과적 노출술, 외과적 노출 후 매복치를 교정하는 방법, 치아이식술, 발치 등이 있다. 이 중 교정적 견인에 사용되는 modified Nance appliance는 환자의 협조를 필요로 하지 않으면서, 견인 와이어를 쉽게 교체할 수 있어서 임상적으로 유용하게 사용될 수 있다. 본 증례들에서 modified Nance appliance를 사용하여 전치, 견치, 대구치 등 상악 내 다양한 위치에 존재하는 매복치의 수술을 동반한 교정적 견인을 시행하여 양호한 결과를 얻었기에 보고하는 바이다.
