Influence of the implant scan body bevel location, implant angulation and position on intraoral scanning accuracy: An in vitro study

To assess the influence of the scan body geometry bevel location and implant angulation and position of complete-arch implant digital scans. Two definitive casts with 4 implant analogs placed parallel (P group) or angulated up to 30° (NP group) were fabricated. Five subgroups were created based on t...

Description
Summary:To assess the influence of the scan body geometry bevel location and implant angulation and position of complete-arch implant digital scans. Two definitive casts with 4 implant analogs placed parallel (P group) or angulated up to 30° (NP group) were fabricated. Five subgroups were created based on the scan body geometry bevel position: facial, mesial, distal, lingual, or random (F, M, D, L, and R subgroup). Casts were digitized using a laboratory scanner (reference) (7Series Desktop Scanner) and an intraoral scanner (TRIOS 3). The implant position discrepancies between the reference and experimental scans were calculated. Data was analyzed using 3-way ANOVA and Tukey tests (α = .05). The scan body geometry bevel position (P
