Reference | Indication | Measurement | Study type | Intraoral/extraoral scanner used | Analogue impression (type) | Reference scanner | Conclusions |
|---|---|---|---|---|---|---|---|
Rutkunas et al. [85] | 48 two-implant retained zirconia FPDs (2,3 and 4 units) | Distance and angulation Screw resistance Clinical fit | In vivo (n = 24 patients) | Trios 3 | PVS (Express) splinted-open tray | D800 | Angulation of more than 10° between the implants could negatively affect the passive fit of the digitally fabricated restorations intraorally Inter-implant distance does not seem to affect the passive fit of restorations, independent on if they are made digitally or conventionally |
