Influence of different manufacturing materials on the accuracy and fitting of full‐arch restorations using a photogrammetry scanner—In vitro study

While photogrammetry provided clinically acceptable capture of implant position, the manufacturing material significantly affected the accuracy and passive fit of full-arch implant-supported restorations produced via photogrammetry-based workflows and alternative solutions should be used to validate the accurary of the manufacturing process in digital workflows. Titanium and zirconia demonstrated the best overall performance, supporting their suitability for final restorations. PMMA may be acceptable for provisional use, while 3D-printed resin showed limited reliability. When checking passive fit, all screws should be tightened simultaneously.
