Precision of Complete-arch Digital Implant Impressions With Intraoral Scanning Versus Photogrammetry

Five intraoral scans, one for each arch before the insertion of scanbodies, were obtained. The implant locations were then marked, and the software trimmed a 6mm diameter circular section of the scan from the implant locations to allow the scanbodies to be added. Abutment-level polyetheretherketone (PEEK) scanbodies were hand-tightened onto each implant and not moved for the remainder of the scans. Scanbodies were scanned using a circular scan path, and scanning was finalized.

Rectangular-shaped titanium photogrammetry scanbodies were hand-tightened onto the Implants. Scanbodies were not moved before completing all scans for each arch. A total of five scans of each arch were obtained using a photogrammetry device. Measurements were successfully recorded by turning them green on the computer screen.
