Introduction.
One of the main steps of impression is the selection and preparation of an appropriate tray.
Hence, the present study aimed to analyze and compare the accuracy of one- and two-stage impression techniques.
Materials and Methods.
A resin laboratory-made model, as the first molar, was prepared by standard method for full crowns with processed preparation finish line of 1 mm depth and convergence angle of 3-4°.
Impression was made 20 times with one-stage technique and 20 times with two-stage technique using an appropriate tray.
To measure the marginal gap, the distance between the restoration margin and preparation finish line of plaster dies was vertically determined in mid mesial, distal, buccal, and lingual (MDBL) regions by a stereomicroscope using a standard method.
Results.
The results of independent test showed that the mean value of the marginal gap obtained by one-stage impression technique was higher than that of two-stage impression technique.
Further, there was no significant difference between one- and two-stage impression techniques in mid buccal region, but a significant difference was reported between the two impression techniques in MDL regions and in general.
Conclusion.
The findings of the present study indicated higher accuracy for two-stage impression technique than for the one-stage impression technique.
