Accuracy Outcomes of Closed-Tray and Open-Tray Impression Techniques for Bone-Level Implants: A Clinical Study

Investigators: Ahy Linah, DMD, implant resident; Connie Kim (DMD 2012)
Funder(s): Straumann

This clinical study compares the accuracy outcomes of two impression techniques, in cases where two bone-level (BL) implants are placed adjacent to each other for a multiunit bridge. In addition, the effect of implant angulations on the choice of impression technique will be assessed on stone models obtained from closed-tray and open-tray impressions. A correlation between the accuracy outcomes and the implant angulations will be sought in order to establish clinical recommendations.
