백색광과 청색광 스캐너를 이용한 지대치 인상체 스캐닝의 반복재현성 비교

다국어 초록 (Multilingual Abstract)

Purpose: The purpose of this study compared of reproducibility of prepared tooth impression scanning utilized with white and blue light scanners. Methods: To evaluate reproducibility with white and blue light scanners, the impression of premolar were rotated by 10°~20° and scanned. These data were compared with the first 3-D data (STL file), and the error sizes were measured (n=5). Independent t test was used to evaluation the reproducibility of impression of premolar with white versus blue light scanners through discrepancies of mean, RMS (α=0.05). Results: Discrepancies of mean with regard to reproducibility were 11.2㎛, 5.8㎛, respectively, with white and blue light scanners (p<0.047). And discrepancies of RMS with regard to reproducibility were 33.4㎛, 18.8㎛, respectively, with white and blue light scanners (p<0.045). Conclusion: Our results indicate a good reproducibility of prepared tooth impression digitized with blue light scanner more than that with white light scanner.
