Description
Yuki Sato and four colleagues tested whether scanning a full dental arch in three segments beats scanning it in one pass. Digital impressions for full-arch implant bridges must be extremely accurate. The laboratory study used a jaw model carrying six implants. A laboratory scanner produced the reference geometry. Three commercial intraoral scanners each performed ten full scans and ten segmented scans, later stitched together.
Accuracy was judged by how much surface fell within fifty micrometers of the reference, plus distances between implant bodies. For two of the three scanners, segmented scanning gave significantly truer surfaces. The third scanner showed no difference between strategies. Distance deviations told a similar story. The twenty twenty-six results suggest splitting the arch helps most scanners overcome full-arch drift.
