PURPOSE This in vitro study evaluated the accuracy of multiple-unit dental implant casts obtained from splinted or nonsplinted direct impression techniques using various splinting materials by comparing the casts to the reference models. The effect of two different impression materials on the accuracy of the implant casts was also evaluated for abutment-level impressions. MATERIALS AND METHOD...

Statement of the Problem Precision of the impression taken from implant positions significantly determines accurate fit of implant-supported prostheses. An imprecise impression may produce prosthesis misfit. Purpose This study aimed to evaluate the accuracy of four impression-making techniques for angulated implants by stereomicroscope through measuring the vertical marginal gaps between the ...

A precise implant impression is essential for the passive fit of an implant superstructure. Although digital impressions are becoming more popular, conventional impression techniques are still frequently used. A direct (pick-up) open tray impression technique uses a guide pin. When an implant is deeply placed, the guide pin may not extend through the hole of the open tray. Therefore, wiping off...
