Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Intraoral Scanning
Digital scanning
Five intraoral scans, one for each arch before the insertion of scanbodies, were obtained. The implant locations were then marked, and the software trimmed a 6mm diameter circular section of the scan from the implant locations to allow the scanbodies to be added. Abutment-level polyetheretherketone (PEEK) scanbodies were hand-tightened onto each implant and not moved for the remainder of the scans. Scanbodies were scanned using a circular scan path, and scanning was finalized.
Photogrammetry Scanning
Photogrammetry
Rectangular-shaped titanium photogrammetry scanbodies were hand-tightened onto the Implants. Scanbodies were not moved before completing all scans for each arch. A total of five scans of each arch were obtained using a photogrammetry device. Measurements were successfully recorded by turning them green on the computer screen.
