Abstract

Background and Aims: Accurate recording of IMPLANT location is required to achieve passive fit and have the IMPLANTs without stress concentration. The aim of this in-vitro study was to evaluate the dimensional and angular ACCURACY of open-tray and closed-tray IMPRESSION techniques using POLYETHER IMPRESSION material and also to assess the surface detail REPRODUCTION of the tooth while IMPRESSION making.Materials and Methods: One reference metal model with 2 IMPLANTs (Implantium) on the position of the maxillary second premolar and first molar and one molar tooth for evaluation of surface details was prepared.27 POLYETHER IMPRESSIONs of these models were made (9 using open-tray, 9 using closed-tray techniques and 9 were made just of the surface of the teeth without any IMPLANTs). IMPRESSIONs were poured with ADA type IV stone.Coordinate Measuring Machine was used for measuring the dimensional ACCURACY and video measuring machine for surface detail REPRODUCTION. All of these measurements were compared with the measurements on the reference model. Data were analyzed by and compared by T-test and One-way ANOVA.Results: There was a significant statistical difference between open-tray and closed-tray techniques (P<0.001).There was no significant difference in the surface detail REPRODUCTION of open-tray and Closed-tray techniques and IMPRESSION making with or without the IMPLANTs (P>0.05).Conclusion: The ACCURACY of open-tray IMPRESSION technique was more than closed-tray technique. The surface detail REPRODUCTION of the tooth was not affected by IMPRESSION technique.
