Statement of problem: A new implant impression technique which use abutments as impression coping, and use resin cement as a splinting material was described. Accuracy of this technique was compared with conventional closed tray and resin splinted open tray technique for a 15¢ªangled 3-implant model
Material and methods: A dental stone master model with 3 linearly positioned implant analogue and a reference framework which was passively fitted to it were fabricated. The center analogue was perpendicular to the plane of model and the outer analogues had a 15¢ªangulation forward or backward. 10 closed tray impressions, 10 resin splinted open tray impressions, 10 abutment-resin framework cementation impressions and 10 abutment-metal framework cementation impressions were made with additional silicone material and poured with dental stone. A light microscope with image processing was used to record the vertical gap dimension between reference framework and analogue of duplicated
cast made with each 4 impression techniques. Statistical analysis used one-way ANOVA with post-hoc tests Tukey test
of .05 level of significance
Results: Significant difference in the vertical gap dimension was found between closed tray technique; 74.3 (¡¾33.4)§ and resin splinted open tray technique, and two other new technique. (P<.05) Abutment-metal framework
cementation technique;42.5 (¡¾11.9)§ was significantly different from resin splinted open tray technique. (P<.05) Abutmentresin framework cementation technique;51.0 (¡¾14.1)§ did not differ significantly from resin splinted open tray technique;50.3 (¡¾16.9)§. (P>.05)
Conclusion: Within limitations of this study, the accuracy of implant level impressions of resin splinted open
tray technique was superior to that of closed tray technique. A new technique using abutment and metal framework cementation was more accurate than resin splinted open tray technique.
