| Abstract | ||||
| Aim: The purpose of this study was to evaluate the wear resistance of three denture teeth materials using the desktop scanner. Materials and methods: Fifteen completely edentulous patients were selected. All the patients received complete maxillary and mandibular dentures. The patients were divided into three groups: Group I patients received maxillary dentures with modified anatomic cross linked acrylic resin denture teeth , Group II received maxillary dentures with nano-hybrid composite teeth . Group III patients received maxillary dentures with light cured composite occlusal surfaces. All the maxillary dentures of the three groups were scanned using desktop scanner. Each scan was carried out at the baseline, 6 and 12 months. The software was used to compare the scanned dentures by superimposing the STL files. Results: There was a significant difference between the light cured composite, the acrylic and composite teeth in both intervals. While there was significant difference between the composite and acrylic teeth in 0-12 months period. At (0-6 months) it was found that the mean of wear in denture teeth made from acrylic resin, composite teeth and light cured composite was 46.13, 44.87 and 36.27 μm . At the interval period (0-12 months), the mean of wear of denture teeth made from acrylic resin, composite teeth and light cured composite was 120.27, 92.07 and 64.53 μm and there was statistical significant differences between the groups where (p<0.001). Conclusion: denture teeth modified with light cured composite resin showed the less total wear compared to acrylic and composite denture teeth. | ||||
