With the introduction of intra-oral scanners and the widely used application of implant-supported prostheses produced using CAD/CAM it is now possible to digitize implant positions directly in the patient’s mouth.
Making intra-oral scans of implants, rather than digitizing plaster casts based on conventional impressions, saves a number of steps in the restorative process. With fewer steps, there is potentially also less risk of errors and discrepancies.
However, digital impression is a fairly new approach and technology and the evidence base found in the literature is still lacking.
This lecture presents aspects of the clinical application of intra-oral scanning and discusses why adopting modern treatment approaches deviating from the conventional modality can be challenging for practitioners, despite the pressure to stay in tune with modern technological developments. Different digital impression systems are presented and the potential and challenges entailed by digital impression techniques are elucidated.
