Accuracy close tray with Acryl pattern impression technique in implant

Aim: This study aimed to investigate the effect of the two impression techniques on the final accuracy of implant casts. Materials & Methods: In this study 4 DIO implant analogues are embedded on a laboratory model & were evaluated with using two impression techniques. In close tray impression technique, it was used of special impression coping of close tray, but in Acrylic technique , it was made Acrylic pattern for any abutments & are connected with duralay acryl. 4final casts are made with each of techniques. The accuracy of final casts was evaluated in 3 dimensions. Measurment of determinate distance was done by CMM with the accuracy of 0.1 micron & the size difference in the final casts with a laboratory model were analyzed by SPSS statistical ware. Results: There was no differences in two techniques on dimension accuracy of the final casts accuracy. Conclusions: The implant impression by Jig technique is as simple as Close tray technique & it is more accurate than Close tray technique in complex cases are preferred.
