Abstract

Objectives: Evaluating the accuracy of measuring tools used to access dimensional stability of complete denture samples.

Materials and Methods: Ten maxillary complete denture bases were made from heat-cure acrylic resin. Six reference points were prepared in each sample in the central incisors area, first premolars area, and first molars area. The distances between 5 different locations (3 horizontal distances and 2 anteroposterior distances) were measured using 3 different measuring tools. Each sample was measured three times using measuring microscope, sagittal cephalometric radiograph in conjunction with auto CAD soft-ware, and Vernier caliper. The results were analyzed using One-way ANOVA and post Tukey test.

Results: the type of measuring tool significantly affect the measurements especially with the radiographs that showed larger values compared to the microscope and Vernier caliper (P<0.05). The latter two measuring tools were equivalent to each other (P >0.05).

Conclusions: within the limitations of the present study, the measuring microscope is the best tool to be used for measuring distances as it provides the best visibility and validity. Vernier calipers is a better alternative for the microscope compare to the radiographs and computer software.
