چکیده
Three abutments were connected to the implants and an electroformed bridge was constructed to fit them. Four groups of impressions were made for the implants using abutments as an impression transfers and the ordinary transfers; both were tightened manually and by 30 N/Cm torque. Impressions were poured into stone using new implant analogues. Another two groups of impressions were made using abutments that were tightened manually and by torque, but the stone models were made using old implant analogues.

Background and Aims: Making accurate impressions of prepared teeth when they are adjacent to dental implants is of great importance. In these situations, disregarding the selection of appropriate impression material and technique, not only can affect accuracy of transferring of the 3-dimentional spatial status of implant, but also can jeopardize the accurate recording of tooth. In the present...
متن کاملThe Accuracy of Four Impression-making Techniques in Angulated Implants Based on Vertical Gap
Statement of the Problem Precision of the impression taken from implant positions significantly determines accurate fit of implant-supported prostheses. An imprecise impression may produce prosthesis misfit. Purpose This study aimed to evaluate the accuracy of four impression-making techniques for angulated implants by stereomicroscope through measuring the vertical marginal gaps between the ...
