Intraoral scans of multiple implants in the edentulous arch are challenged by absence a distinct surface morphology between scan bodies. A aid was applied such situation and evaluated for intraoral scanning accuracy vivo.87 22 patients were scanned with (SA) without (NO) using two different scanners (CS3600 [CS] TRIOS3 [TR]). Master casts digitized laboratory scanner. Virtual models superimposed an inspection software Linear deviation precision measured. Statistical analysis performed linear mixed (α = .05).Total mean within CS group 189 μm 135 when aid. The TR group's total 165 Significant improvement observed (p .001), no difference found group. 96% bodies successfully TR-SA compared to 86% TR-NO group, 83% CS-SA, 70% CS-NO respectively.The improved unsplinted but not These differences could originate from technologies used, active triangulation (CS) confocal microscopy (TR). ability recognize both systems, which have favorable clinical impact overall.
