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.

| Scanning with verification jig | Other | 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. |
| Measure | Description | Time Frame |
|---|---|---|
| Vertical Deviation | Analogues Saved from the Intraoral scan and those saved from stone model were superimposed. The vertical discrepancy (mm) in implant position between intraoral digital scanning and verification jig-based stone model in All-on-4 implant cases. | through study completion, an average of 1 year |
| Angular deviation | Analogues Saved from the Intraoral scan and those saved from stone model were superimposed. The angular difference (degrees) in implant position between intraoral digital scanning and verification jig-based stone model in All-on-4 implant cases. | through study completion, an average of 1 year |
| Horizontal deviation | Analogues Saved from the Intraoral scan and those saved from stone model were superimposed. The horizontal discrepancy (mm) in implant position between intraoral digital scanning and verification jig-based stone model in All-on-4 implant cases. | through study completion, an average of 1 year |

| Direct intraoral scanning | Other | 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. |
