Edentulous Jaw Clinical Trial
Official title:
The Accuracy of Intraoral Scanning and Photogrammetry on the Clinical Fit of Long-span Frameworks
The goal of this cross-over clinical trial is to investigate the precision of digital implant impressions using an intraoral scanner and photogrammetry in obtaining complete-arch implant-supported scans. The main question[s] it aims to answer are: - Is there a difference in precision between intraoral scans and photogrammetry in obtaining digital implant scans? - Will arch perimeter and jaw type (maxilla vs. mandible) affect the precision results? Procedures: At each appointment, participants existing permanent/temporary prosthesis or healing caps were unscrewed and temporarily removed for the period of the consultation appointment. Scanbodies were screwed into their implants for the duration of the appointment. They underwent two types of digital implant impression procedures (five times each), including intraoral scan and photogrammetry. Intraoral and extraoral photography were taken. At the end of each appointment, the scanbodies were removed, and existing bridge/healing caps were reinserted. The procedures were not painful or required any form of local anesthetic Comparison group: Researchers compared the precision of intraoral scanning vs. photogrammetry to see which device provided the best precision outcomes.
