Influence of implant reference on the scanning accuracy of complete arch implant scans captured by using a photogrammetry system

ConclusionsImplant reference impacted the accuracy of complete arch implant scans obtained by using the photogrammetry system tested. However, a trueness ±precision linear discrepancy of 6 ±3  µm and an angular discrepancy of 0.01 ±0.01 degrees were measured among the groups tested; therefore, the impact of the discrepancy measured should not be clinically significant. Clinical ImplicationsThe selection of the reference implant does not impact the accuracy of the photogrammetry system tested; however, marking the implant placed on the right and most posterior tooth location as the implant reference is recommended to maximize the accuracy of the photogrammetry system tested.
