Nylon denture base material (Lucitone FRS) was studied for its mechanical properties. The study confirmed that flexible denture base material has lower values in terms of hardness.

The purpose of this study was to propose a new numerical modeling of the glass fiber cloth reinforced denture base resin (GFRP). The proposed model is constructed with an isotropic shell, beam and orthotropic shell elements representing the outmost resin, interlaminar resin and glass fiber cloth, respectively. The proposed model was applied to the failure progress analysis under three-point ben...

Dear Readers, Denture-induced stomatitis is the most common type of oral candidosis and the most frequent mucosal alteration associated with complete or removable partial dentures in the elderly. Despite being an infection of multifactorial etiology, this condition has as main etiological factor the colonization of denture-bearing mucosa and acrylic bases by species of Candida spp., especially ...

This study evaluated the effect of disinfection methods [chemical disinfection (immersion in 100 ppm chloride solution) or microwave disinfection (690 W for 6 min)] on the internal adaptation of denture bases and resin surface roughness. For the adaptation test, 18 maxillary denture bases were obtained from stone casts duplicated from a metallic master model and submitted to the following treat...

Papaspyridakos and Lal Papaspyridakos and Lal The dental literature is replete with techniques for registering maxillomandibular relationships and transferring them accurately to the articulator. For edentulous patients receiving implants, several methods have been described for articulating the definitive implant cast at the appropriate occlusal vertical dimension (OVD) in the centric relation...

PURPOSE The discoloration of acrylic resin denture bases may lead to significant esthetic problems. The aim of this in vitro study was to investigate the effects of frequently consumed drinks on the color changes of fresh and aged, heat-polymerized, conventional acrylic resin. MATERIALS AND METHODS Eighty-four, heat-polymerized acrylic resin specimens (4 mm x 5 mm x 30 mm) were fabricated. Ha...

acrylic resin denture bases undergo dimensional changes during polymerization. injection molding techniques are reported to reduce these changes and thereby improve physical properties of denture bases. the aim of this study was to compare dimensional changes of specimens processed by conventional and injection-molding techniques.sr-ivocap triplex hot resin was used for conventional pressure-pa...

STATEMENT OF PROBLEM Most processed resin denture bases do not fit the cast accurately because of polymerization changes in the resin. The fit is more noticeable in the palate between the denture base and the cast. Therefore, development of a polymerization system that will improve the fit of a denture base to the cast is lack of worth considering to improve the fit and retention of the denture...

Candida albicans adhesion and proliferation on denture bases may lead to denture stomatitis, which is a common and recurrent problem in denture wearers. The goal of this study was to assess the inhibitory effect of thymoquinone incorporated in the polymethyl methacrylate denture base material against Candida albicans. Eighty acrylic resin specimens were fabricated and divided into eight groups ...
