Statement of the problem. The fracture of acrylic resin dentures remains an unsolved problem. Therefore, many investigations have been performed and various approaches to strengthening acrylic resin, for example, the reinforcement of heat-cured acrylic resin using glass fibers, have been suggested over the years. But problems such as poor workability, rough surface, poor adhesion of glass fiber...

this study aimed to evaluate the cellular toxicity of two newly-released acrylic resins (futura gen and gc reline hard) in comparison with the conventional heat-cure resin (meliodent).sample discs from each acrylic resin were placed in 24-well culture plates along with l929 mouse fibroblast cell line. a mixture of the rpmi 1640 medium, antibiotics and 10% fbs was added to the plates and the spe...

The fracture resistance of polymethylmethacrylate (PMMA) as the most popular denture base material is not satisfactory. Different factors can be involved in denture fracture. Among them, flexural fatigue and impact are the most common failure mechanisms of an acrylic denture base. It has been shown that there is a correlation between the static strength and fatigue life of composite resins. The...

BACKGROUND Flexural strength (FS) of denture base resins (DBRs) had been improved by reinforcing it with different glass fibers. However, a limited data are available on the effect of glass fiber reinforcement with conventional heat-cured resin after prolonged water storage. AIMS AND OBJECTIVES This study aimed to evaluate the reinforcing effect of novel S-glass and nylon fibers on the FS of ...

OBJECTIVES Ease of denture cleaning is of paramount importance in geriatric patients and those with limited dexterity. We have previously investigated methods of coating dentures with titanium dioxide (TiO2 ) and reported the effects (self-cleaning and antibacterial) of such treatments in in vitro studies. This study was to verify the biocompatibility of a TiO2 -coated acrylic resin produced by...

Background and Aim: It has been commonly believed that, denture cleansers have detrimental effects on the surface structure of denture base materials. The purpose of this study was to evaluate the effects on surface roughness of 4 different commercially available chemical cleaning agents (Polident, Corega Tabs, Fittydent, Efferdent) and sodium hypochlorite on the denture base materials. Materia...

Background and Objectives: Acrylic resin had a long history of been used in the fabrication denture since they exhibit better chemical bond between teeth base. With increasing use dentures, detachment from dentures also increased proportionally. Denture disinfection is an essential procedure for maintaining good hygiene denture. The aim study to evaluate effect on shear strength heat activated ...

One of the reconstructive choices for the completely edentulous patient is the placement of multiple implants and the fabrication of a fixed implant-supported complete denture. These patients experience an improvement in masticatory performance over patients who wear complete dentures. The fixed-implant complete denture consists of a metal bar with acrylic resin and denture teeth connected to i...
