The stability of mandibular complete dentures may be improved by reducing the transverse forces on the denture base through linear (noninterceptive) occlusion, selecting an occlusal plane that reduces horizontal vectors of force at occlusal contact, and utilizing a central bearing intraoral gothic arch tracing to record jaw relations. This article is intended to acquaint the reader with one tec...

PURPOSE This laboratory study aimed to investigate the effect of doping an acrylic denture base resin material with nanoparticles of ZnO, CaO, and TiO2 on biofilm formation. MATERIALS AND METHODS Standardized specimens of a commercially available cold-curing acrylic denture base resin material were doped with 0.1, 0.2, 0.4, or 0.8 wt% commercially available ZnO, CaO, and TiO2 nanopowder. Ener...

Polymethyl methacrylate (PMMA) is one of the most widely used materials in prosthetic dentistry. Since it was introduced to dentistry, it has been successfully used in construction of denture bases. Acrylic resins have been successful as denture bases because of their ease of processing, low cost, light weight, and colour matching ability,however, acrylic resin denture base materials are low in...

The purpose of this study was to evaluate the effect of degradation of a denture base resin on bond strength to relining resins. Denture base resin specimens were immersed under various conditions to simulate degradation. Tensile bond strength of denture base resin after immersion to relining resins was measured with or without surface grinding. The bond strength of denture base resin without g...

Purpose: Some patients experience adverse reactions to poly(methyl methacrylate)-based (PMMA) dentures. Polyamide (PA) as an alternative to PMMA has, however, not been well documented with regard to water sorption and water solubility. The aim of this in vitro study was to measure water sorption and water solubility of two PA materials compared with PMMA, and to evaluate the major components re...

The system composed by mucosa, saliva and denture is complex and dependent of many variables. The decreased or absent flow of saliva induces a high disconfort which has to be reduced by all means, this meaning use of artificial saliva and improvement of surface characteristics of the denture base material. We investigated five materials produced by classic tehnology (press-pack moulding + diffe...
