Abstract
It is of interest to compare the accuracy of three different
impression techniques for a single tooth impression. We used 3
groups with 15
samples each in this study. Group 1: Putty and light body in a
sectional stock tray; Group 2: Monophase and extra light body in a
sectional
stock tray; Group 3: Matrix impression technique. 15 impressions
were taken of a prepared tooth on a typodont with each technique.
The
dimensions of the casts poured from these impression techniques were
compared with the control typodont tooth. Data analysis shows that
the matrix impression technique gave the best results in terms of
dimensional study followed by monophase and extra light body
impression technique and putty and light body impression technique
gave the least accurate results. The results show that there is a
statistically significant difference between the three impression
techniques in terms of dimensional stability. Data analysis shows
that the
matrix impression technique gave the best results in terms of
dimensional study followed by monophase and extra light body
impression
technique and putty and light body impression technique gave the
least accurate results. The variations between the groups are within
acceptable limits. Hence, it can be concluded that all the
impression techniques will result in adequate dimensional stability
and can be
used in clinical scenarios.
