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

Abstract

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

Materials & Methods: Customized trays were utilized to create impressions using polyether and vinylsiloxane ether materials. Mann whitney U test was done. The results were analysed using SPSS software.

Results: The highest mean deviation from the master cast dimension was observed in the closed tray method.

Conclusion: In closed tray impression technique, both polyether and vinyl siloxanether showed same results.

 Keywords: implant, closed tray technique.
