This presentation presents novel digital approaches that can reshape the workflow of modern restorative procedures. In a time in which digital dentistry is on the constant rise of meeting patient expectations in a “one-visit procedure”, with promising results delivered by the ever-growing CAD/CAM technology, practitioners must yet come up with innovative digital tools or techniques to reduce chairside time yet deliver predictable outcomes.

This presentation will present three main procedures: indirect digital impressions for CAD/CAM post and core, fully digital workflow for printed upper and lower full dentures, and a simplified gingival retraction technique for digital impressions.

Regarding CAD/CAM post and cores, the presentation will showcase how intraoral digital impressions are used with CAD software to design customized post and cores. With 3D printers, these posts are rapidly printed on site, using castable ‚printed wax‘ material.

Next, a key highlight of the presented workflow for digital complete dentures is the integration of the combined use of a central bearing device (Massad Jaw Recorder Device) with an optical jaw tracking device (Modjaw) to design complete dentures according to the patient’s functional jaw motion and centric relation. The workflow includes printed try-in denture, printed denture base and printed teeth for the final full denture.

Lastly, a soon to be published gingival retraction technique for digital impressions will be presented. Gingival retraction is undoubtedly a tedious process that clinicians spend much chairside time on in their prosthodontic workflow. Thus, this technique proposes a cordless gingival retraction method using a combination of retraction paste, PTFE tape and a chairside fabricated index from gingiva barrier light-cured material that can be used when obtaining intraoral impressions by using intraoral scanners (IOS).  

In summary, the presentation will appeal to users of digital dentistry by easing their everyday dental procedures and meanwhile making the best out of their digital tools.
