简要总结
This clinical trial evaluates the accuracy of two digital impression techniques intraoral photogrammetry and intraoral scanning in patients rehabilitated with full-arch implant-supported prostheses (All-on-4 and All-on-6 concepts).
详细描述
The study aims to evaluate and compare two digital impression techniques, intraoral scanning and intraoral photogrammetry methods in terms of precision, accuracy (using conventional impression technique as reference), and passive fit of complete-arch implant supported restorations. The trial is an in vivo comparative study with direct 3D deviation analysis and evaluation.
