Abstract

A total of 580 patients, who visited and received an orthodontic diagnosis in the Department of Pediatric Dentistry, Seoul National University Dental Hospital from 2017 to 2019, were investigated in this study. The aim of this study was to evaluate skeletal patterns of pediatric orthodontic patients determined with lateral cephalometric analysis and to analyze the relationship between skeletal pattern and probable associated clinical features. Also, the modality of orthodontic treatment for each skeletal classification was investigated to aid in therapeutic decisions. Patients aged 7 year accounted for the largest age group; 54.2% of patients showed a skeletal class I pattern, 22.2% showed a skeletal class II pattern, and 23.6% showed a skeletal class III pattern. Bi-maxillary retrusion for skeletal class I, retruded mandible with normal positioning of the maxilla for skeletal class II, and retrusion of the maxilla with protrusion of the mandible for skeletal class III were the largest subgroups by skeletal pattern. Brachyfacial type accounted for 55.0% of patients, followed by 31.9% of mesofacial type and 13.1% of dolichofacial type. The prevalence of anterior crossbite in the study was 43.3%, higher than that in previous studies.

이번 연구는 2017 - 2019년에 서울대학교치과병원 소아치과에 내원하여 교정 진단을 받은 580명의 환자를 대상으로 조사를 시행하였다. 이 연구는 소아치과에 내원하는 교정환자의 골격 형태를 측모두부방사선 분석으로 파악하고 골격 형태와 관련된 임상적 특징과의 상관관계를 분석하고자 하였다. 또한, 골격 형태에 따라 행해진 치료방법에 대해 조사하여 임상의가 교정치료 계획 수립시 도움이 되고자 시행되었다. 연령분포는 7세 연령군이 교정진단을 받은 환자 중 가장 많은 분포를 차지하였다. 골격분포는 골격성 1급 부정교합이 54.2%로 가장 많았고 2급은 22.2%, 3급은 23.6%를 차지하였다. 골격성 1급의 경우 상하악 모두 후퇴인 환자가 34.4%, 골격성 2급의 경우 상악은 정상범주이나 하악이 후퇴인 경우가 39.5%, 골격성 3급의 경우 상악 후퇴 및 하악 전돌이 35.0%로 가장 높은 비율을 보였다. 수직적 골격형태는 brachyfacial type이 55%으로 가장 많았고 mesofacial type은 31.9%, dolichofacial type은 13.1%로 나타났다. 전체 환자 중 43.3%가 전치부 반대교합을 보였다.
