Assessing the Effect of Interimplant Distance and Angle on Different Impression Techniques

We aimed to evaluate the trueness of digital and conventional impression techniques based on different angles distances between implants deviation caused by angle distance parameters varying implants. Eight were placed in a polyurethane edentulous mandibular model at distances. After obtaining 3-dimensional (3D) reference using an optical scanner, was scanned with three intraoral scanners: Cerec Omnicam (DO), Trios 3 (DT), Carestream 3500 (DC). Then, master casts obtained from impressions (C) also digitized, all data imported into reverse engineering software be compared 3D model. Distance measurements adjacent performed, analyzed ANOVA–Tukey Kruskal Wallis tests. The significance level accepted as p < 0.05. While DT C groups gave best results for high interimplant distances, scanners found superior method closer At higher angulations, angular group significantly lower. short showed superiority, decreased angulations.
