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).
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.

Study Protocol
The full study protocol will be made available beginning 1 year after publication of the primary results in a peer-reviewed journal and ending 2 years after the publication of results.
The full study protocol will be shared upon reasonable request to qualified researchers . Requests should be submitted to the principal investigator via institutional email. Data will be provided after approval of the proposal and completion of a data agreement to ensure appropriate use of the data. Shared files will be transmitted through a secure institutional repository.
