교정적 견인과 감압술에 의한 매복된 하악 제1대구치의 치험례 Orthodontic Traction and Decompression Method in Treating Impacted Permanent Mandibular First Molars : Case Reports원문보기
매복치는 유치열기보다 영구치열기에서 더 높은 빈도로 발생한다. 가장 흔하게 이환되는 치아는 상하악 제3대구치들이며, 하악 제1대구치의 매복은 비교적 드문 편이다. 매복치의 치료방법은 자발적 맹출을 위한 지속적인 검사, 외과적 노출술, 외과적 노출 후 아탈구, 교정적 견인, 그리고 외과적 재위치술 등이 있으며 이 모든 치료가 실패한다면 치아를 발거하는 것을 고려할 수 있다. 첫 번째 증례는 8세 남아로서 매복된 하악 제1대구치에 폐쇄장치를 이용한 감압술을 시행하였으며, 정기적인 검진을 통해 치아의 맹출이 관찰되었다. 두 번째 증례는 12세 남아로서 매복된 하악 제1대구치의 외과적 노출술을 시행 후 치아의 맹출이 관찰되지 않아 가철성 장치를 이용한 교정적 정출술을 시행하였으며 이 후 정상적인 치아의 맹출이 관찰되었다.

Impacted teeth occur at higher frequencies in permanent than primary dentition. The most frequently affected teeth are the maxillary and mandibular third molars, whereas it is quite uncommon for the mandibular first molar to be impacted. Treatment methods for impacted teeth include continuous examination for independent eruption, surgical exposure, subluxation after surgical exposure, orthodontic traction, and surgical repositioning. If all of these treatments fail, tooth extraction may be considered. In the first case study, an 8-year-old boy was treated with surgical exposure, after which he was fitted with an obturator. His mandibular first molar then erupted successfully. In the second case, we treated a 12 year-old boy using orthodontic traction. This study describes children with tooth eruption disorders of the mandibular first molar in mixed dentition, and reports acceptable results regarding treatment of the impacted teeth.

가설 설정
(B) Panoramic view. (C) Cone beam computed tomography view: the crown and roots of the right mandibular first molar were in a normal formation.
Decompression using a Penrose drain was considered. The Penrose drain is inexpensive and causes little discomfort.
제안 방법
The patient was informed to clasp and replace the orthodontic intermaxillary rubber band between the hook of the removable appliance and the ligature wire of the lingual button. Clinical and radiological check-ups were performed monthly. 11 months after insertion, the appliance was removed.
1-B). Next, a cone beam computed tomography (CBCT) scan was performed to more specifically observe the relative locations of the tooth and lesion (CB Mercury, Hitachi, Tokyo, Japan; Fig. 1-C).
5-B). The patient was informed to clasp and replace the orthodontic intermaxillary rubber band between the hook of the removable appliance and the ligature wire of the lingual button. Clinical and radiological check-ups were performed monthly.
Case 1. Treatment procedure (A) A surgical approach, removing the gingiva and alveolar bone above the impacted left mandibular first molar was used to induce eruption of the impacted left mandibular first molar. (B) Obturator appliance.
대상 데이터
A 12-year-old boy was referred to the Department of Pediatric Dentistry, Chosun University Dental Hospital with the chief complaint of an unerupted right mandibular tooth from the local dental hospital (L/C). Before referral, the patient was treated with surgical exposure at L/C for spontaneous eruption of the right mandibular first molar, but this treatment failed.
Case 2. A 12-year-old boy. On his first visit, the non-erupted state of the right mandibular first molar.
An 8-year-old boy was referred to the Department of Pediatric Dentistry, Chosun University Dental Hospital with the chief complaint of an unerupted left mandibular tooth. There was no family history or relevant medical history.
