"목적: 구강 스캐너를 이용해 상악, 하악 스캔을 시행 후 교합 스캔을 하는 과정에서 어떠한 범위를 스캔했을 때 가장 정확한 교합 인기가 되는지를 파악하고자 하였다. 연구 재료 및 방법: 성인 30명을 대상으로 교합지를 사용하여 교합점을 채득하고 이를 기준으로 다양한 범위의 협측 교합 스캔의 결과를 비교하였다. 총 5개 영역(상악 치아를 기준으로 좌우 양측의 제1소구치에서 제2소구치, 제1소구치에서 제1대구치, 제1소구치에서 제2대구치, 제2소구치에서 제1대구치, 양측 견치)의 협측 교합 스캔을 시행하였으며, 이후 협측 교합 스캔파일을 CAD 프로그램을 통해 해당하는 범위 치아의 협측 부위만 남겨두고 데이터 편집 및 정렬을 통해 스캔 파일에서 교합 되는 영역을 확인하였다. 이후 교합지로 얻어진 교합점과 스캔 파일에서 얻어진 교합 영역의 일치도를 비교하였으며, 등분산성 T-test를 통해 통계 분석하였다(α = 0.05). 결과: 각 그룹간 정렬 성공률과 정렬 실패율은 양측 견치에서는 각각 77.23%, 40.85%로 나타났고, 양측 제1소구치에서 제2소구치에서 각각 68.23%, 28.89%, 양측 제1소구치에서 제1대구치에서 63.76%, 29.97%, 양측 제1소구치에서 제2대구치에서는 61.31%, 32.04%, 그리고 양측 제2소구치에서 제1대구치는 67.55%, 27.46%로 나타났다. 양측 견치에서의 결과는 상악 모든 구치부 스캔 결과와 비교했을 때 정렬 성공률과 실패율 모두 높은 양상이 나타났다. 정렬 성공률에서 구치부를 스캔 범위에 따른 통계적 유의성은 나타나지 않았으나, 구치부와 양측 견치의 결과 비교에서는 양측 제2소구치에서 제1대구치의 스캔 결과를 제외하고 통계적 유의성이 관찰되었다. 정렬 실패율에서는 구치부 스캔 범위에 따른 통계적 유의성은 나타나지 않았고, 구치부와 양측 견치의 결과에서는 모두 통계적 유의성이 관찰되었다. 결론: 교합 협측 스캔 채득 시 전치부를 스캔할 경우 구치부를 스캔할 때보다 교합 되는 영역이 더 많이 나타나며, 구치부를 스캔할 경우 범위에 따른 교합 인기의 유의미한 차이는 나타나지 않는다.
Abstract
"Purpose: The aim of this study was to determine which scan range would provide the most accurate bite registration when performing a bite scan after scanning an upper and lower arch using an intraoral scanner. Materials and Methods: The occlusal contact points were recorded using articulating paper for 30 adults, and the results of various ranges of buccal bite scan were compared based on this. Buccal bite scan of 5 ranges (1st premolar to 2nd premolar, 1st premolar to 1st molar, 1st premolar to 2nd molar, 2nd premolar to 1st molar, and canines to another side canine of the maxillary teeth) was performed, and then the buccal bite scan file was used in a CAD program to confirm the occlusal area in the scan file through data editing and alignment, leaving the buccal area of the teeth. Afterwards, the degree of agreement between the occlusal contact points obtained from the articulating paper and the occlusal area obtained from the scan file was compared, and statistical analysis was performed using the homoscedastic T-test (α = 0.05). Results: The alignment success and alignment failure rates among each group were 77.23% and 40.85% in canine to another side canine, 68.23% and 28.89% in bilateral first premolar to second premolar, 63.76% and 29.97% in bilateral first premolar to first molar, 61.31% and 32.04% in bilateral first premolar to second molar, 67.55% and 27.46% in second premolar to first molar. The results of the anterior scan of both canines showed higher alignment success and failure rates compared to the scan results of all maxillary posterior teeth. In the alignment success rate, statistical significance was not found depending on the scan range of the posterior teeth, but in comparing the results of the posterior teeth and both canines, statistical significance was observed except for the scan results of the second premolar to the first molar. There was no statistical significance in the alignment failure rate depending on the scan range of the posterior teeth, and statistical significance was observed in the results of the posterior teeth and both canines. Conclusion: When taking a buccal bite scan, in the case of scanning the anterior teeth, more occlusal area appear than when scanning the posterior teeth, and in the case of scanning the posterior teeth, there is no significant difference in the bite registration depending on the scan range.
