Accuracy of the digital workflow for implant-supported restorations depends on clinical situation, selected scanning and 3D printing devices, as well as the use of different strategies. Therefore, digital workflow strategy for different clinical cases should be planned differently in order to maximize the accuracy. Results of several clinical and laboratory studies are presented in order to get a more comprehensive view about accuracy of digital workflow in different clinical situations. The following aspects of accuracy were investigated:
1. in-vitro and in-vivo digital implant impressions in partial- and fully-edentulous situations with different intraoral scanners (IOS) considering scan body positions and inter-arch distances;
2. repositioning accuracy of prosthetic components;
3. 3D printing strategies for the implant master cast;
4. effect of hybrid digital-analogue workflow.

Results of these studies are illustrated with several clinical examples, showing clinical effect of hybrid workflow, when digital and analogue approach is combined in order to improve the fit of the implant-supported restorations.
