Abstract
Background: The aim of this study was to verify the influence of high expansion dental stone and teeth on the adaptation of maxillary complete dentures. Materials and Methods: Maxillary complete dentures/bases were processed on type III dental stone and high expansion dental stone casts. The gap-space between the acrylic denture base and the cast in the posterior palatal seal area was measured by using dino-lite digital microscope. A comparison was made between G1 and G2, G3 and G4 to evaluate the influence of dental stone on the adaptation accuracy and another comparison between G1 and G3, G2 and G4 was made to evaluate the influence of teeth on the adaptation accuracy of maxillary complete denture. Results: Statistical analysis of the data revealed that the fitness of maxillary complete denture base was significantly improved in some points with high expansion dental stone compared to dental stone type III and the presence of teeth reduced the gap-space in the posterior palatal seal area when dentures with teeth were compared with denture bases without teeth (p<0.05). Conclusions: Using the high expansion dental stone and presence of teeth would influence the adaptation accuracy of denture base which in turn would improve the quality of the dentures
