ABSTRACT
PURPOSE:
This study compared the accuracy of an abutment-framework (A-F) taken with open tray impression technique combining cementon crown abutments, a metal framework and resin cement to closed tray and resin-splinted open tray impression techniques for the 3-implant definitive casts. The effect of angulation on the accuracy of these 3 techniques was also evaluated. MATERIAL ANDMETHODS:
Three definitive casts, each with 3 linearly positioned implant analogs at relative angulations 0, 30, and 40 degrees, were fabricated with passively fitted corresponding reference frameworks. Ten impressions were made and poured, using each of the 3 techniques on each of the 3 definitive casts. To record the vertical gap between reference frameworks and analogs in duplicate casts, a light microscope with image processing was used. Data were analyzed by two-way analysis of variance and the Tukey test.RESULTS:
The open tray techniques showed significantly smaller vertical gaps compare to closed tray technique (P .05).CONCLUSION:
The accuracy of the A-F impression technique was superior to that of conventional techniques, and was not affected by the angulation of the implants.
