Influence of the ambient color lighting on the accuracy of complete arch implant scans recorded by using two intraoral scanners
Objectives: To measure the influence of scanning pattern on the accuracy, time, and number of photograms of complete-arch intraoral implant scans. Methods: A maxillary edentulous patient with 7 implants was selected. The reference implant cast was obtained using conventional methods (7Series Scanner...

| Resumo: | Objectives: To measure the influence of scanning pattern on the accuracy, time, and number of photograms of complete-arch intraoral implant scans. Methods: A maxillary edentulous patient with 7 implants was selected. The reference implant cast was obtained using conventional methods (7Series Scanner). Four groups were created based on the scanning pattern used to acquire the complete-arch implant scans by using an intraoral scanner (IOS) (Trios4): manufacturer’s recom- mended (Occlusal-Buccal-Lingual (OBL)), zig-zag (Zig-zag), circumferential (Circumf), and novel pattern that included locking an initial occlusal scan (O-Lock group) (n = 15). Scanning time and number of photograms were recorded. The linear and angular measurements were used to assess scanning accuracy. One-way ANOVA and Tukey tests were used to analyze trueness, scanning time, and number of photograms. The Levene test was selected to assess precision (α=0.05). Results: Statistically significant differences in trueness were detected among OBL, Zig-zag, Circumf, and O-Lock regarding linear discrepancy (P < 0.01), angular discrepancy (P < 0.01), scanning time (P < 0.01), and number of photograms (P < 0.01). The O-Lock (63 ± 20 μm) showed the best linear trueness with statistically significant differences (P < 0.01) with Circumferential (86 ± 16 μm) and OBL (87 ± 19 μm) groups. The O-Lock (93.5 ± 13.4 s, 1080 ± 104 photograms) and Circumf groups (102.9 ± 15.1 s, 1112 ± 179 photograms) obtained lower scanning times (P < 0.01) and number of photograms (P < 0.01) than OBL (130.3 ± 19.4 s, 1293 ± 161 pho- tograms) and Zig-zag (125.7 ± 22.1 s, 1316 ± 160 photograms) groups. Conclusions: The scanning patterns tested influenced scanning accuracy, time, and number of photograms of the complete-arch scans obtained by using the IOS tested. The zig-zag and O-Lock scanning patterns are recom- mended to obtain complete-arch implant scans when using the selected IOS. |
