초록
골격성 I급이면서 수직적으로 정상인 환자 160명(남자 80명, 여자 80명)의 측모 두부방사선 계측사진을 대상으로 하악 전치부 치조골의 협설측 두께를 치축을 기준으로 계측하여 연령에 따른 차이를 조사하여 다음과 같은 결과를 얻었다. 하악전치부 치조골의 협설측 두께와 하악 전치부 설측 치조골의 두께는 연령이 증가함에 따라 여자의 CEJ 하방 2 mm 부위를 제외하고는 남녀 모두에서 유의한 감소를 보였다. 반면에, 하악 전치부 협측 치조골의 두께와 하악 이부 최대 풍융부의 두께는 연령이 증가함에 따라 유의한 차이를 보이지 않았다. 이상의 연구를 통하여 한국인에 있어서 수평적으로 I급의 골격형태이면서 수직적으로 정상인 환자에서는 성인보다는 성장기환자에서 하악 전치의 설측 치조골의 두께가 더 두꺼워 발치치료에서와 같은 하악 전치의 설측이동이 유리할 것으로 사료된다.

Abstract
Objective: The purpose of this study was to determine the changes of mandibular anterior alveolar bone thickness with age. Methods: Cephalometric radiographs of 160 skeletal class I patients (male 80, female 80) with normal vertical growth pattern was investigated by measuring the buccolingual thickness of mandibular alveolar bone on the basis of root axis. Results: As the age increases, both male and female showed a significant decrease in buccolingual width of the mandibular anterior alveolar bone and in the width of mandibular anterior lingual alveolar bone except the CEJ area of females. However, there was no significant difference in the thickness of mandibular anterior buccal alveolar bone and in the width of maximum prominence of mandibular symphysis with age. Conclusion: From the above results, it is concluded that Korean children whose growth pattern is sagittally skeletal class I with a vertical normal growth pattern have a greater mandibular anterior lingual alveolar bone width than Korean adults; therefore, lingual movement of mandibular incisors, which is usually accompanied in extraction treatment, is considered to be more preferable in younger patients.
