dc.description.abstract | PURPOSE. To compare and analyze trueness and precision of provisional crowns made using stereolithography apparatus and subtractive technology. MATERIALS AND METHODS. Digital impressions were made using a master model and an intraoral scanner and the crowns were designed with CAD software; in total, 22 crowns were produced. After superimposing CAD design data and scan data using a 3D program, quantitative and qualitative data were obtained for analysis of trueness and precision. Statistical analysis was performed using normality test combined with Levene test for equal variance analysis and independent sample t-test. Type 1 error was set at 0.05. RESULTS. Trueness for the outer and inner surfaces of the SLA crown (SLAG) were 49.6 +/- 9.3 mu m and 22.5 +/- 5.1 mu m, respectively, and those of the subtractive crown (SUBC) were 31.8 +/- 7.5 mu m and 14.6 +/- 1.2 mu m, respectively. Precision values for the outer and inner surfaces of the SLAC were 18.7 +/- 6.2 mu m and 26.9 +/- 8.5 pm, and those of the SUBC were 25.4 +/- 3.1 mu m and 13.8 +/- 0.6 mu m, respectively. Trueness values for the outer and inner surfaces of the SLAC and SUBC showed statistically significant differences (P<.001). Precision for the inner surface showed significance (P<.03), whereas that for the outer surface showed no significance (P<.58). CONCLUSION. The study demonstrates that provisional crowns produced by subtractive technology are superior to crowns fabricated by stereolithography in terms of accuracy. | - |
