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.

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.

문제 정의
This report presents three cases of impacted teeth that were treated with modified Nance appliance as well as a review of previous studies.
제안 방법
After 3 months of traction using the modified Nance appliance followed by 8 months of additional orthodontic procedures on the maxillary arch, the left maxillary incisor was positioned adequately in the dental arch(Fig. 3). A fixed retainer was bonded on the lingual side of the maxillary incisors.
After 5 months of traction using modified Nance appliance followed by 20 months of second phase orthodontic procedures, treatment was completed. The left maxillary canine was positioned adequately in the dental arch with enough width of attached gingiva(Fig.
It can be utilized in either a unilateral or bilateral loss of maxillary second primary molars or multiple molars[5]. In this study, it was used for space maintenance and anchorage reinforcement. It consists of bands cemented on molars with a connecting palatal arch made of 0.
Approximately 60 gm of force was applied. The patient was checked at monthly intervals to monitor the traction force and adjust the appliance. After 3 months, #21 emerged into the oral cavity.
This case report presents treatment procedures for impacted teeth using modified Nance appliance. It is a new type of fixed orthodontic appliance that facilitates convenient exchange of traction wires by attaching a bracket on the resin button of the Nance holding arch.
대상 데이터
A 7-year-old girl was referred from a local clinic with chief complaint of a missing maxillary anterior tooth. The patient had no significant medical history.
A 9-year-old girl was referred from a local clinic with chief complaint of an impacted permanent maxillary left canine. The patient had no significant medical history.
An 11-year-old boy was referred from a local clinic with chief complaint of an unerupted molar. The patient had no signifi-cant medical history.
In this study, it was used for space maintenance and anchorage reinforcement. It consists of bands cemented on molars with a connecting palatal arch made of 0.9 mm stainless steel wire and palatal button made of acrylic resin. Modified Nance appliance has a bracket embedded on the resin button of the Nance appliance.
성능/효과
11). Over 28 months of clinical and radiographic follow up, no abnormal findings such as root resorption were observed(Fig. 12).
