What this trial studies

This clinical trial aims to compare the accuracy and patient satisfaction of three different methods for taking full-arch impressions in edentulous patients with osseointegrated implants. The methods being evaluated include conventional impressions, intraoral scanning, and digital photogrammetry. Each patient will undergo all three impression techniques, with satisfaction measured through a Visual Analogue Scale and the time taken for each method recorded. The study seeks to determine which method provides the best precision and patient experience.

Who should consider this trial

Good fit: Ideal candidates for this study are edentulous patients with 4 to 8 osseointegrated implants in either the maxilla or mandible.

Not a fit: Patients with non-osseointegrated implants or those with incomplete edentulism may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved accuracy and satisfaction in dental implant procedures for patients.

How similar studies have performed: Other studies have shown promising results with similar approaches, indicating potential for success in this trial.
