New system to capture dental impressions for complete arch restorations

The Use of a New Stereophotogrammetry System to Capture Intra-operative Complete-arch Impression

Observational University of Rome Tor Vergata · NCT06745232

This study is testing a new way to take dental impressions for patients getting complete arch restorations to see if it can improve the fit and comfort of their temporary dental prosthetics.

What this trial studies

This observational study focuses on patients requiring complete arch restorations using a dynamic navigation system for implant placement. After the implants are positioned, a novel stereophotogrammetry system will be employed to accurately capture the implant positions, facilitating the delivery of a fixed screw-retained interim prosthesis. The study aims to improve the precision of dental impressions, potentially enhancing patient outcomes in prosthetic dentistry.

Who should consider this trial

Good fit: Ideal candidates are healthy adults aged 18 and older with specific bone dimensions and conditions suitable for implant placement.

Not a fit: Patients with significant medical or psychiatric conditions, untreated periodontitis, or those undergoing certain therapies may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more accurate dental impressions and improved prosthetic outcomes for patients.

How similar studies have performed: While the use of stereophotogrammetry in dental applications is emerging, this specific approach has not been widely tested in prior studies.
