ABSTRACT

Purpose: To evaluate the efficiency between three different scanners in the College of Dentistry in King Saud bin Abdulaziz University for Health Sciences (KSAU-HS) in terms of obtaining accurate 3D models. Methodology: Five pairs of plaster casts were selected randomly from the clinics of KSAUHS. The casts were scanned using three different 3D scanners to create 3D models and printed using a 3D printer. Mesh Lab 2016 software was used to evaluate the accuracy of the printed models by superimposing the original scanned casts on the printed casts. A hand held calliper was used to measure selected distances to compare between the plaster casts and the printed models. Results: Statistical analyses were done using Graph Pad Prism 5. Kruskal-Wallis test showed no statistically significant difference in the accuracy between the scanners, P =.166. K-related test for the manually measured casts showed no statistically significant difference in the accuracy between the scanners, P =.433. The three scanners showed substantial differences in terms of scanning time. Conclusion: No variations were detected in the accuracy of the printed and original models.
