Abstract:
Achieving accurate impressions of crown and bridge preparations remains a challenge for practicing dentists despite numerous material and technique advances. Precise material placement around the prepared tooth, proper management of soft tissue, and timely dispensing of both wash and tray materials are among the difficulties. As demonstrated in two cases presented, a new pneumatic impression device has been developed as a means of enabling clinicians to create precision impressions more easily, without the need for retraction cord or retraction paste.
