초록
본 연구는 Quick Ceph Image Pro™(ver 3.0)와 국내에서 개발되어 사용 중인 V-Ceph™(ver. 3.5) 2 종의 비디오 이미지 예측 프로그램의 수술 후 연조직 측모의 정확성과 신뢰성에 대해서 알아보고자 시행되었다. 골격성 III급 부정교합으로 진단되어 수술 전 교정 치료를 받고, 하악골 후퇴 수술(body osteotomy 또는 SSRO)을 시행한 남녀 환자 각각 20명을 대상으로 하였다. 나이는 평균 21.4 ± 4세이고, 수술 전 측모두부방사선계측사진은 수술 전 평균 21.1일에, 수술 후 측모두부방사선계측사진은 수술 후 평균 335.7일에 촬영되었으며, 예측치와 실측치 차이를 비교하였다. 연구결과 Quick Ceph과 V-Ceph 모두 예측치와 실측치 사이에 크기와 방향에 있어서 오차가 관찰되었으며, 이러한 오차는 상순과 하순, 턱과 연관된 항목에서 크게 나타났다 (p < 0.05). Quick Ceph은 A', Ls, Li의 수평적 위치 및 각 부분에서의 연조직 두께(U1-Ls, L1-Li, Pog-Pog')의 수평거리 예측에서, V-Ceph은 하순의 수직적 위치 예측에서 오차가 컸다 (p < 0.05). V-Ceph의 경우 하악골의 이동양이 증가할 때 Sn의 수직적 위치, Ls의 수평적 위치, 상순의 연조직 두께(U1-Ls)처럼 상순과 연관된 계측치에서 예측오차가 컸으며, Quick Ceph의 경우 하악골의 이동양이 증가할 때 하순의 수평위치 및 하순의 두께에서의 예측오차가 작았다 (p < 0.05). 또한, 연조직의 두께에 따른 오차를 평가한 결과, Quick Ceph의 경우 상순과 하순의 두께가 두꺼울수록 각각에 관련된 연조직 예측의 오차가 컸으며 (p < 0.05), V-Ceph의 경우 하순과 턱의 연조직 두께가 두꺼울수록 턱의 연조직 예측의 오차가 크게 관찰되었다 (p < 0.05). 그러나, 본 연구에서의 모든 예측오차값은 3 mm 이내로 계측되었으며, 이러한 오차 범주는 임상적으로 허용 가능한 수준인 것으로 생각된다.
Abstract
The purpose of this study was to test and compare the accuracy and reliability of soft tissue profile predictions generated from two computer software programs (Quick Ceph Image ProTM (ver 3.0) and V-CephTM (ver 3.5)) for mandibular set-back surgery. The presurgical and postsurgical lateral cephalograms of 40 patients (20 males and 20 females) were traced on the same acetate paper with the reference taken as the cranial base outline. The presurgical skeletal outlines were digitized onto each computer program and the mandible was moved to mimic the expected surgical procedure with reference to the mandibular anterior border and lower incisor position of the actual postsurgical skeletal outline. The soft tissue profile was generated and the amount and direction of skeletal movement was calculated with each software. The predicted soft tissue profile was compared to the actual postsurgical soft tissue profile. There were differences between the actual and the predicted surgical soft tissue profile changes in the magnitude and direction, especially the upper lip, lower lip and the soft tissue chin (p < 0.05). Quick Ceph had more horizontal measurement errors and thickness errors for the upper lip and lower lip, but V-Ceph had more vertical measurement errors of the lower lip (p < 0.05). There was a positive correlation between the prediction errors and the amount of mandibular movements in the vertical position of Sn, the horizontal position of Ls and the upper lip thickness for V-Ceph, and there was a negative correlation in the horizontal position and the thickness of the lower lip for Quick Ceph (p < 0.05). However, all of the prediction errors of both imaging softwares were ranged within 3 mm, and this was considered to be allowable clinically.
