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...

AIM Silver colloidal nanoparticles have been incorporated into acrylic resins to induce antimicrobial properties. However, as additives, they can influence the mechanical properties of the final product. Mechanical properties are also dependent on different curing cycles. The aim of this study was to evaluate flexural strength of a denture base resin incorporated with different concentrations o...

STATEMENT OF PROBLEM Despite the numerous positive features of acrylic denture base, there are a number of undeniable associated disadvantages. The properties of denture base have been improved through various interventions including application of different types of filler and coatings. OBJECTIVES This study aimed to evaluate the surface roughness, thickness and coating quality of organic-in...

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...

BACKGROUND Regular usage of denture cleansers is recommended in complete denture wearers for effective plaque control, and these cleansers alter the physical properties of acrylic resin over a period of time. Thus, an in vitro study was carried out to assess the effect of denture cleansers on the color stability of heat-cure denture base resin. AIM The aim of the present study was to evaluate...

Computer-aided design and computer-aided manufacturing (CAD/CAM) denture base manufacturers claim to produce their resin pucks under high heat and pressure. Therefore, CAD/CAM dentures are assumed to have enhanced mechanical properties and, as a result, are often produced with lower denture base thicknesses than conventional, manually fabricated dentures. The aim of this study was to investigat...

This study explored a method for fabricating removable complete denture aided by CAD&RP technology. 3D crossing section scanner and laser scanner were respectively applied to obtain the surface data of artificial teeth, edentulous models and rims made in clinic. The vertical and horizontal relations of models were recorded before scanning with a special device. A 3D graphic database of artifici...

Despite therapeutic progress, opportunistic oral fungal infectious diseases have increased in prevalence, especially in denture wearers. The combination of entrapment of yeast cells in irregularities in denture-base and denture-relining materials, poor oral hygiene and several systemic factors are the most probable cause for the onset of this infectious disease. Hence, colonization and growth o...
