Abstract

Despite digitalization in dentistry, conventional impression techniques are still generally used for fabricating multi-unit implant prostheses. Among these techniques, the open-tray impression technique is known to be accurate. Open trays have occlusal windows to access impression coping, and the space might cause inaccurate impressions due to a lack of supporting structures. This technical report introduces a simple method to rigidly seal the occlusal window on open trays with type II modeling compounds.
