Protocol for Indirect Restoration Intraoral Scanning Under Dental Dam Isolation


Now online in the Journal of Prosthodontics, a report on an intraoral scanning protocol for indirect restorations utilizing dental dam isolation.

The technique described consists of an initial scan of both arches and their occlusion. Dental preparations are performed under isolation with a dental dam, followed by intraoral scanning with the dental dam in place.

Scanning with the dental dam in place allows for control of some distortion factors, such as the presence of saliva and blood. It also minimizes the interruption of the scanner's stitching process caused by tongue or soft tissue movement, resulting in quicker and higher quality scans.

The authors note that this protocol can be integrated into both chair-side and outsourced computer-aided manufacturing (CAM) digital workflows and in both cases, the resulting higher quality scan will allow a better marginal and internal fit of the final restoration.
