Purpose: The purpose of this study is to evaluate the discrepancy of scan process in dental intra oral scanner by comparing model scanner and anticipate possibility to introduce intra oral scan technique. Methods: 3D superimposition test was conducted to compare the scan discrepancy. The scanners used in this study are the e-oral scanner, the D750 model scanner, and the high precision CMM(3D Coordinate Measuring Machine). The standard of accuracy verification is ISO 5725-1; trueness and precision. Master model was manufactured by dental stone and scanned 5 times by intra oral, model scanner. Reference data was scanned 5 times by high accuracy CMM to evaluate the trueness. Results: Trueness of D750 scanner were 7.4 ㎛ 5.1 ㎛ 6.8 ㎛ at an abutment, an occluasal, a specific area. and trueness of e-scanner were 20.2 ㎛ 27.4 ㎛ 37.8 ㎛ at an abutment, an occluasal, a specific area. Precision of D750 scanner was 7.04 ㎛, e-scanner was 15.95 ㎛. Conclusion: When conducting in vitro test, The mean difference of trueness between e-scanner and D750 were 12.8 ㎛ at an abutment area, 22.3 ㎛ at an occlusal area, 31.0 ㎛ at a specific area and 8.91 ㎛ in precision. The scan discrepancies are within the range of clinical acceptance.
