"목적: 본 연구의 목적은 전악 고정성 보철치료 조건에서 임시 보철물로 확립된 상하악의 관계를 구강스캐너를 통하여 교합스캔을 채득하고 디지털 방식으로 마운팅할 때 교합면간기록의 정확성을 조사하는 것이다. 연구 재료 및 방법: 덴티폼 모형을 사용하여 교합기에서 최대 교두간 접촉위로 부착한 후 상악 전체 치아를 삭제하였다. 임시 보철물을 제작하고 교합 조정을 시행하였다. 삭제한 악궁을 스캔한 뒤, 전치부 혹은 구치부 교합스캔을 통해 디지털 마운팅을 시행하였다. 위치된 교합면간기록의 정확성을 3차원적인 위치 편차와 교합평면의 각도 오차를 통해 평가하였다. 이후 부분 무치악 모델에서도 동일한 절차를 반복하여 디지털 교합면간기록의 정확성을 평가하였다. 통계에는 Kruskal-Wallis 검정과 Mann-Whitney U 검정이 이용되었고, 유의수준은 0.05로 설정하였다. 결과: 디지털 방식으로 설정된 교합면간기록에서 치아 정중부의 위치 오차는 스캔 영역과 잔존 치아 조건에 따라 유의한 차이가 없었다(P = 0.53). 교합평면의 각도 오차는 전치부를 중첩 영역으로 사용했을 때 크게 나타났으며, 양측 구치부를 중첩 영역으로 사용한 경우 작은 오차값을 보였다(P < 0.001). 결론: 전악 고정성 보철 치료 시 임시 보철물로 확립된 상하악 관계를 디지털 방식으로 마운팅을 할 때 양측 구치부 교합스캔 자료를 사용하는 것이 추천된다."
Abstract
"Purpose: The purpose of this study was to investigate the accuracy of digital mounting with occlusal scans in the interocclusal record for a full-mouth fixed prosthetic treatment condition. Materials and Methods: The entire maxillary teeth were prepared in a dentiform model and attached to an articulator in maximum intercuspation. Temporary crowns were fabricated and occlusion was adjusted. After scanning the arch with tooth preparation, digital mounting was performed using an occlusion scan of the anterior or posterior teeth areas. The accuracy of the positioned jaw relation was evaluated three-dimensionally through positional deviation and angular error of the occlusal plane. Afterwards, the same procedure was repeated on the partially edentulous model to evaluate the accuracy of digital interocclusal record. Kruskal-Wallis test and Mann-Whitney U test were used for statistical analysis, and the significance level was set at 0.05. Results: There was no significant difference in the positional error at the center of the arch in the digitally established jaw relation depending on the scan area used and remaining tooth conditions (P = 0.53). The angular error of the occlusal plane was larger when the anterior teeth were used as the overlapping area, and a smaller error value was observed when both posterior teeth were used as the overlapping area (P < 0.001). Conclusion: The use of bilateral posterior occlusal scans is recommended when digitally mounting the jaw relation established with temporary teeth during full-mouth fixed prosthetic treatment."
