Summary

The aim of this study is to assess the three-dimensional accuracy of direct intraoral scanning in All-on-4 implant-supported prostheses by comparing intraoral scan data with a custom-made verification jig.

Conditions

• Edentulism

Interventions

Type	Name	Description
OTHER	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.
OTHER	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.
