Study Groups

Scanning with the aid of jig
Scanning with verification jig
Comparing Relative Implant Positions of the 4 implants in each case obtained through desktop scanning of intraoral provisional verification jig. All-on-4 treatment for mandibular and maxillary edentulous cases were scanned using the Medit i700 intraoral scanner. Scan data were imported into Exocad software, where scan-body matching was performed using the Neodent library to determine the positions of multiunit abutment analogues.
Scanning without jig
Direct intraoral scanning
Comparing Relative Implant Positions of the 4 implants in each case obtained through direct intraoral scanning without jig. All-on-4 treatment for mandibular and maxillary edentulous cases were scanned using the Medit i700 intraoral scanner. Scan data were imported into Exocad software, where scan-body matching was performed using the Neodent library to determine the positions of multiunit abutment analogues.
