Abstract

Background and Aim: The wear resistance of acrylic teeth plays an important role in denture longevity. The purpose of this study was to compare the TOOTH WEAR rate of three Iranian manufactured artificial teeth with the one manufactured in Italy.Materials and Methods: In this experimental in vitro study four brands of artificial teeth including IVOCLAR, Glamour, Apple and B.star were used. Sixteen mandibular molars were selected from each band. Eight samples from each brand of teeth were loaded under 2 Kg compressive forces in the presence of artificial saliva. The aluminum oxide mullet was used with 5000 and 10000 cycles. The other 8 samples were loaded under a 4Kg compressive force under the same conditions. The data were analyzed with ANOVA test.Results: The results showed that weight loss (wear) by aluminum oxide mullet under 2kg force, 5000 cycle, for acrylic teeth was as follows: IVOCLAR 0.0097 ± 0.0028, Glamor 0.0122 ± 0.0037, Apple 0.0120±00038And B.star 0.0098 ± 0.0030mgr. Also, under the same conditions and at 10, 000 cycle, the weight loss was 0.0123 ± 0.0023, 0.0156 ± 0.0042, 0.0147 ± 0.0039 and B.Star 0.0119 ± 0.0029mg respectively. There is not significant differences between the groups.. (p<0.4).by increasing the force to 4 Kg there is not significant differences between the groups (p<0.5).Conclusion: The results of this in-vitro study showed that there is not any significant differences between wear resistance in four brand of artificial acrylic teeth.
