Purpose : This study evaluated the accuracy of a sectional stock tray for making impressions.Materials and Methods : A sectional stock tray is a full arch tray sectioned into right and left halves that can be reconnected with a tray handle. An impression of a maxillary model (500A, Nissin, Japan) with four reference points was made with two types of silicone impression material (Injection and Hard types, Exafine, GC, Japan). Five casts (Vel-mix stone, Whipmix, KY) were fabricated for each tray (total of 10 casts). Impression accuracy was evaluated by measuring the four distances between the reference points (mm) using a Profile projector (x50, V-16E, Nikon, Japan). The results (n=5) were analyzed by ANOVA/Duncans test (α=0.10)Results : Making impressions should be easier with this sectional stock tray. There were no significant differences (p>0.10) between the sectional stock tray and a conventional stock tray.Conclusion : Impression accuracy of the sectional stock tray with dowel-plug holes was confirmed.
