Each implant had an implant abutment (SRA RB Abutment). To obtain the reference file (control), an optical marker (iCam4D scan body) was hand tightened on each implant abutment, and 10 consecutive PG scans were obtained by using a calibrated extraoral PG system (iCam4D). Four groups were created depending on the system used to capture the position of the implants: Grammee, MicronMapper, Elite, and IOConnect (n=10).
