The Influence of Laboratory Scanner Versus Intra-Oral Scanner on Determining the Implant Axis by Using Three Different Scan Abutments

Background: The purpose of this in vitro study was to compare the implant axis’ spatial position and orientation by using laboratory scanner versus intra-oral with three different scan abutments. Methods: A 3D model printed an internal hex analog place teeth 35#. Three standard abutments were used: MIS (two-piece titanium), AB PEEK titanium base) ZZ (one-piece PEEK). Each abutment scanned 30 times TRIOS E3 (laboratory scanner) Omnicam (intra-oral scanner). For each scan, STL (stereolithography) file created, characterization measured X, Y, Z coordinates, rotational longitudinal angles. comparison between all scans conducted superimposition files, a software. t-test Wilcoxon signed-rank test used. (p < 0.05) Results: Only showed no statistical difference X axes. 0.05). All other angle twice Conclusions: deviation axis scanner. greatest (1.04 degrees) while two deviations about half degree relation abutment. There is need for further studies which will examine influence geometry, material, parts on accuracy obtained.
