초록
이 연구의 목적은 디지털 치열 모형에서 치아 폭경, 볼튼 비율, 수평 피개, 수직 피개를 포함한 교정적 측정의 타당성을 확인하는 것이다. 만 12 - 18세의 환자를 대상으로 세가지 형태의 치열 모형을 획득하였다. 기존의 석고 모형을 형성하였고, DOF freedom HD 모형스캐너를 통해 디지털 모형으로 변환하였다. 그리고 CS3600 구강 스캐너로 디지털 모형을 형성하였다. 각 모형에서 측정 시행 후, 급내 상관 계수를 통해 계측의 신뢰성과 재현성을 확인하였으며, 대응 표본 t 검정을 사용하여 타당성을 평가하였다. 결과적으로 모든 군에서 급내 상관계수는 0.750을 초과하여 연구자 내 신뢰성과 연구자 간 재현성이 있음을 확인하였다. 모형 스캔한 군은 전체 및 전치 볼튼 비율, 수평 및 수직 피개에서 타당성을 보였다. 구강 스캔한 군은 전치 볼튼 비율, 수평 피개에서 타당성을보였다. 구강 스캔한 디지털 모형을 이용한 계측은 인상 채득에 어려움이 있는 소아 청소년에게 고려할 수 있는 대안이다. 하지만 임상에서이를 교정적 분석에 이용할 경우 오차를 고려한 적용이 필요하다.
Abstract
The aim of the present study is to evaluate the validity of orthodontic measurements including tooth width, Bolton ratio, overjet and overbite on the digital dental models. Dental models of the subjects aged 12 to 18 were obtained in 3 different forms, which were conventional stone model, digital model created with Freedom HD model scanner, and digital model produced with CS3600 intraoral scanner. After measurements were made on the models, reliability and reproducibility of the measurements were evaluated by using intraclass correlation coefficient, while validity was assessed with paired t-test. As a result, significant reliability and reproducibility were verified, with intraclass correlation coefficient exceeding 0.750 in all groups. Measurements of the model scanned group showed an adequate validity in overall and anterior Bolton ratio, overjet, and overbite. Intraoral scanned models showed an adequate validity in anterior Bolton ratio, and overjet. Measurement on intraoral scanned digital models can be considered as an alternative for young children who have difficulty in taking impression. Furthermore, careful considerations on measurement error should be made in clinical situations.
