Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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 virtual fit of complete-arch implant supported restorations. The trial is an in vivo cross over study with direct 3D deviation analysis and evaluation.
