Assessment of Wear Resistance of Three Commercially Available Different Denture Teeth: A Comparative Study

The current study's aim was to assess the wear resistance of three commercially available, distinct denture teeth.

A total of 60 denture teeth were considered. There were 20 corresponding artificial denture teeth in each group: Group I: Vivodent-highly cross-linked PMMA, group II: Finex-UDMA, Inorganic filler, group III: Vita Physiodens-PMMA, inorganic microparticle filler. Steel split molds measuring 6 mm in diameter and 30 mm in length were used to develop acrylic rods. Before wear testing, all teeth were kept in distilled water at 37°C for 24 hours to allow for water absorption. Using a load of 300 grams, wear testing was carried out by repeatedly sliding the contact in the buccolingual direction at 4.5 cycles/s and 20 mm sliding distance each cycle. A digital measuring microscope was used to measure each tooth's height (mm) both before and after the wear test, with an accuracy of 0.001 mm. Data was recorded and statistically analyzed.

At baseline, the mean tooth wear in the Vivodent group was 10.20 ± 0.04, the Finex group was 10.34 ± 0.08, and the Vita Physiodens group was 10.16 ± 0.06. There was no significant difference between the denture teeth groups. After 1,00,000 cycles, the minimal tooth wear was found in Vita Physiodens groups, i.e., 9.68 ± 0.12, followed by Vivodent group (9.36 ± 0.02) and Finex group (9.22 ± 0.10). There was a significant difference obtained between the three denture tooth groups.

In conclusion, the current study found that the Vita Physiodens groups had the least amount of tooth wear, followed by the Vivodent and Finex groups.

In order to preserve the long-term functioning of artificial teeth in dental prosthesis, wear resistance is one of the characteristics that must be taken into account. The tooth's construction technique, composition, chewing force, and connection to the antagonist tooth can all change this characteristic. In clinical dentistry, wear or degradation of intraoral usable materials is an issue. Tooth wear is still an important problem for those with artificial teeth.
