Comparative evaluation of positional accuracy in multiple implant using open tray impression technique with different impression material: an in-vitro study

Abstract

Background: To evaluate positional accuracy in multiple implant using open tray impression technique with different impression material.

Materials & Methods: Polyether and vinylsiloxan ether materials were employed to create impressions using customized trays. 15 open tray impressions were performed using polyether, with splinted impression transfer copings held in place by auto-polymerizing acrylic resin and 15 with vinyl siloxane ether. The result was analysed using SPSS software.

 Results: The non-splinted method showcased a higher mean deviation from the master cast dimension in comparison to the splinted method.

Conclusion: When utilizing the open tray technique, polyether material demonstrated superior outcomes.

Keywords: impressions, open tray, polyether.
