_Introduction Basedonstudiesontheaccuracyofthescanning methods employed1, 2, as well as the resulting mod- els3, 4 and restorations5–7, it appears that the com- bination of intra-oral scans and CAD/CAM-based restorations is today regarded as standard in con- ventional prosthetics. The question that arises is how this workflow is realised for implant pros- theses. The special requirements of implants for intra-oral scanning have led to changes in the information to be transferred and to the principles of the present implant workflow. This needs to be considered when developing a scanning protocol for implant-borne restorations. _Case report A 48-year-old female patient presented with a gap that had been left untreated for many years after extraction of tooth 46. The adjacent teeth had beenrestoredprostheticallyandwerefreeofcaries. It was decided to provide restoration with an im- plant rather than a bridge restoration. Owing to the lack of loading, bone resorption had already commenced in a buccolingual direction.
