Resumo: | Objective: to evaluate the impact of three different scan strategies and implant angulation on impression accuracyof an intraoral scanner for full-arch multiple implant scan. Material and Method: A maxillary edentulous modelwith six implant analogs served as a reference model. The four anterior analogs were positioned parallel toeach other, the distal right and the distal left was placed with an angulation of 15o and 20o, respectively. Thirtyimpression were performed using an intraoral scanner (CEREC Primescan). The master cast was digitalized withan industrial reference scanner (ATOS Core 80). All scans were converted to standard tessellation language (STL),superimposed on the reference scan with a 3d inspection software (GOM Inspect Professional 2019) and thenanalyzed. Results: All linear distances presented equivalence [p<0.01] to those found on the reference scan forall scan strategies. All scan strategies presented a tendency of negative means for linear distances except for d4in strategy C. All angular distances did not present equivalence [p=0.05] to those found on the reference scan.Significant 3D deviations [p<0.05] were found between strategy B (0.02 ± 0.01) and C (0.05 ± 0.04) for d1.In all others linear and angular distances no statistically significant difference was found between strategies A,B and C. Conclusions: There was no statistically significant difference between strategies A, B and C except ford1 in strategy B and C; Implant angulation did not affect the accuracy of the CEREC Primescan IOS.KEYWORDSPrecision; Trueness; Edentulous jaw; Dental implant; Dental impression technique. |
