The objective of this study was to examine the availability of the new impression coping by comparing with conventional
coping in implant pick-up impression technique. Five implant fixtures were installed on #14, 21, 23, 25, 27 in acrylic resin
model. That model with 5 fixtures was standard model, which was divided 3 groups; using new flag type impression
coping, conventional impression coping splinted with self-curing resin, conventional impression coping without splinting.
We made metal circular cones for calculation 3-dimensional coordinates by attaching to implant fixtures or analogs.
Three-dimensional relationships of each model were calculated. Data was analyzed by multiple ANOVA and Bonferroni.
The accuracy of impression between using new flag type impression coping and conventional impression coping did not
show differences in 3 ? dimensional analysis.Within limitations of this study, the new flag type impression coping is
available in implant pick-up impression technique.
