Brief Summary:
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 questions 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 permanenttemporary 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 bridgehealing 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
