Abstract

Aim: To compare 3-Dimensional accuracy of open and closed impression technique using three elastomeric impression materials to transfer the intraoral position of implant fixture to the working cast.
Objective: To compare 3-Dimensional accuracy of open and closed tray impression technique by using addition silicone, condensation silicone and polyether impression materials for making implant level impressions.
Materials and Methods: Experiments was conducted to find the three dimensional accuracy of casts made with three impression materials for implant impressions by open and closed tray impression techniques. Five implant analogs were placed on a maxillary acrylic model; impression posts were screwed to implant analogs. 30 stock trays and 30 open window custom trays were prepared. These 30 stock trays and 30 open window custom trays were again divided into three subgroups by using three impression materials. Then the impressions were poured using die stone according to manufacturer’s instructions. Specific dimensions of resultant cast was measured. The dimensional changes were measured using White light laser scanner and data analysis was done by XOV Rapidform Software.
Comparison between materials was done by ANOVA test followed by Tukey’smultiple comparison test. Comparison between two techniques was done by unpaired‘t’ test.
Results: The data was subjected to statistical analysis which was done by ANOVA test followed by Tukey’s multiple comparison test and Comparison between two techniques was done by unpaired‘t’ test. Statistical analysis shows significantly less difference in open tray technique when compared to closed tray impression technique.
Conclusion: Within the limitation of this study;1. Open tray impression technique is more accurate than the closed tray impression technique for making implant impression; 2. Polyether and Addition silicone elastomeric impression materials were there commended materials for implant impressions.
