The purpose of this study was to evaluate the fabrication of a complete denture using a CAD/CAM system. Cone beam CT was used to measure the complete denture and the artificial teeth. After a 3D complete denture image was structured using 3D CAD software, we factored out the artificial teeth and obtained a 3D denture base image. A machining center cut an acrylic resin block, and fabricated an a...

This case report describes a simple method for identifying the citizenship of a denture wearer by marking the telephone country code number inside the denture base. A wax pattern for the denture framework was prepared on the refractory cast. A piece of embossing tape, containing the country code (81, Japan), Japanese prefectural code, and abbreviation of the dental clinic where the denture was ...

STATEMENT OF PROBLEM The occurrence porosity in polymethyl methacrylate, the most commonly used denture base material is a problem. The occurrence of oral candidiasis and other infections has also been reported in denture users. PURPOSE The aim of this study was to evaluate the effect of addition of an antimicrobial agent, silver zeolite on the porosity of denture base resin, which will be an...

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...

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...

background and aims. the aim of this study was to compare flexural strength of specimens processed by conventional and injection-molding techniques. materials and methods. conventional pressure-packed pmma was used for conventional pressure-packed and injection-molded pmma was used for injection-molding techniques. after processing, 15 specimens were stored in distilled water at room temperatur...

statement of problem: fracture strength of a denture base resin is of great concern, and many approaches have been used to strengthen acrylic resin dentures. purpose: the aim of this study was to measure the transverse strength of a heat polymerized acrylic resin, after reinforcement with metal wire and two types of glass fibers. materials and methods: forty rectangular specimens (65.0×10.0×3.3...

PURPOSE The aim of our study was to explore the effects of different loading positions on the movements of the abutment tooth and denture base of removable partial denture with unilaterally designed framework (RPD-U). MATERIALS AND METHODS The experiment was carried out with a simulation model of a mandible without left molars. The movements of abutment tooth and denture base of the unilatera...

Objectives; This study was carried out to compare the posterior palatal base distortion of denture bases processed with ProBase Hot to those processed by conventional heat cure acrylic resin (Acrostone) before and after water immersion. Study design; Twenty waxed denture bases were prepared for U-shaped palatine arch form, ten for each denture base material. Waxed denture bases were flasked, pa...

It is a denture type micro electric field loading device design. The device is a removable partial denture, and there are a power supply and the electrode plate in the denture. The electrode plate embedded in the denture base, electrode embedded in the buccal and lingual base, between the base and the artificial teeth is the power supply, the power supply and both sides electrodes connected by ...
