[4-9] Various authors have suggested the use of organic solvents such as chloroform acetone, methyl methacrylate (MMA), and methyl chloride to increase the bond strength of resilient liner to denture base material. [5, 8] Similarly, authors have advocated sandblasting the denture base to create a roughened surface to improve the adhesive bond.
[6] Watri (2010) examined the addition of chopped strand glass fiber with 1%, 1.5%, and 2% concentration in heat-polymerized acrylic resins (QC 20), reported that there was an increased in impact strength and transverse strength with the addition of 1% glass fiber while the addition of 2% glass fiber can reduce the transverse strength of heat-polymerized denture base material.

Recently, some new types of polymers have been proposed as denture base materials with the purpose of achieving favourable aesthetic outcome, biocompatibility especially for patients who are allergic to conventional metals and resin monomers, higher elasticity than conventional heatpolymerizing resins, sufficient strength for use as a denture base material.
Lesions of the oral mucosa associated with the wearing of dentures may represent acute or chronic reactions to microbial denture plaque, a reaction to constituents of the denture base material, or a mechanical denture injury.
On reaching the dough stage, i.e., when it separates cleanly from the sides of the mixing jar, the denture base material was kneaded thoroughly and packed into the mold space.
This study was undertaken to evaluate and compare the flexural strength of two commonly used flexible denture base resins with conventional heat cured PMMA denture base resins available in the market and select the best denture base material for the clinical situation.
The results oppose those of a study26 in which disinfection with hypochlorite solution did not influence the hardness of the denture base material.
They can be classified as thermoplastic acetal, thermoplastic polycarbonates, thermoplastic acrylic and thermoplastic nylon (polyamides).9 However, the desired denture base material has not been developed yet.
The use of computed tomography in the detection of radiolucent denture base material in the chest.
Clinical function may induce stresses, which, after a period of a few years bring about deterioration in the denture base material and so hasten failure.
The effects of various disinfectant solutions on the surface hardness of an acrylic resin denture base material. Int J Prosthodont 1993; 6: 9-12.
- Due to the method of processing the acrylic resin for denture bases at fifty times the conventional processing pressure, there is less porosity, and denture base material may have less C.
