Precision, Patient Satisfaction and Timing of Complete-arch Digital Implant Impression Using Conventional Impression, Intraoral Scanner, and Photogrammetry Techniques

What this Trial Is About

Researchers are evaluating the precision of different implant-supported impression techniques in patients without teeth (edentulous) who have 4 to 8 osseointegrated implants in the upper or lower jaw. This clinical trial compares conventional impressions, intraoral scanners, and photogrammetry to determine which method provides the most accurate complete-arch impression. Additionally, the study aims to assess patient satisfaction with these new impression methods. Each participant will undergo six impressions in total: two with an intraoral scanner, two with photogrammetry, and two conventional plaster impressions using an open tray technique. The procedures are performed twice per method on the same day. After each type of impression, patients will complete a satisfaction questionnaire using a Visual Analogue Scale (VAS) to rate comfort, anxiety, taste, nausea, pain, and treatment length. The time taken for each impression is also recorded. Participants will attend a single appointment lasting about one hour during which all impressions and questionnaires are completed. Researchers will analyze the repeatability and precision of each impression technique and collect patient-reported outcome measures. The primary outcome is the precision of the complete-arch impression, and secondary outcomes include patient satisfaction ratings. This study includes safety monitoring and careful data collection to understand the patient experience with these digital and conventional impression methods.
