dc.description.abstract | Purpose: The purpose of this study is to compare and analyze the accuracy of single crownsbased on the type of occlusal surface. Methods: A single crown wax pattern was fabricated in three types of occlusal surface. Theprepared wax pattern was replicated with silicone, and stone was injected to create a stonemodel. The prepared specimens were scanned using a model scanner. Scans were classifiedinto three groups, and each scan was performed six times to analyze the trueness andprecision of a single crown. In addition, only the occlusal surface area was analyzed for truenessand precision. Data were analyzed using the Kruskal–Wallis H test, a nonparametrictest (α=0.05). Results: With regard to the trueness value of the occlusal scan area, the no occlusal toothattrition (NA) group showed the largest error of 3.5 μm, and the complete occlusal tooth attrition(CA) group showed the lowest value of 3.1 μm. The NA group had the greatest precision,and the medium occlusal tooth attrition (MA) group and CA group showed a low precisionvalue of 3.2 μm; the difference between the groups was statistically significant (α=0.05). Inthe color difference map, the CA group showed a lower error than the NA group. Conclusion: The occlusal surface with severe attrition had excellent accuracy, but the accuracyof the group without attrition was low. There were significant differences betweengroups, but clinically acceptable values were shown. | - |
