Aim: The aim of this study was to evaluate the transverse strength of three kinds of heat-cured acrylic resin (Meliodent HC, Acron HC, Lucitone 199); one kind of microwave-cured acrylic resin (Acron MC); one kind of visible light-cured resin (Triad VLC); and one kind of self-cured acrylic resin (Meliodent SC). Method: A total of 60 specimens (65 mm x 10 mm x 3 mm) were fabricated, ten from each...

Denture base resins are extensively used in dentistry for a variety of purposes. These materials can be classified as chemical, heat, light, and microwave polymerization materials depending upon the factor which starts the polymerization reaction. Their applications include use during denture base construction, relining existing dentures, and for fabrication of orthodontic removable appliances....

In chronic recording experiments, self-curing dental acrylic resins have been used as a mounting base of electrodes or microdialysis-probes. Since these acrylics do not bond to the bone, screws have been used as anchors. However, in small experimental animals like finches or mouse, their craniums are very fragile and can not successfully hold the anchors. In this report, we propose a new applic...

Resistance to impact fracture and high flexural strength are desirable properties of denture base acrylics. The purpose of this laboratory study was to determine the Izod impact strength, the flexural strength, the flexural modulus, and the yield distance for four premium denture resins. Bar specimens 86 x 11 x 3 mm of Lucitone 199, Fricke Hi-I, ProBase Hot, and Sledgehammer Maxipack were fabri...

Introduction: Denture stomatitis is a common complication in patients wearing dentures and preventing the proliferation of related microorganisms and their induced infections is noteworthy. The aim of the present study was to assess the antimicrobial effect of acrylic resins containing various concentrations of silver nanoparticles, on Candida albicans and Streptococcus mutans. Materials and Me...

One approach to the study of wear involves the ch~~te~zation of surface failure under conditions of single-pass sliding. Such an approach has been used to show that the wear of commercial and experimental restorative resins and composites is determined by the resistance of the material to penetration and by the mode of deformation during sliding [l] . The purpose of this investigation was to ch...

Aim: The aim of this study was to evaluate the influence of acrylic resin immersion in different mouthwashes on hardness, roughness and color. Methods: Specimens of an orthodontic selfcured acrylic resin (Orto Clas®) were produced and immersed in five mouthwashes: Plax® Classic (Colgate®); Plax® alcohol-free (Colgate®); Listerine® (Johnson & Johnson®); Periogard® (Colgate®) and Periogard® alcoh...

Objective This in vitro study evaluated the disinfection action of peracetic acid on chemically activated acrylic resin. Methods Sixty chemically activated acrylic resin specimens were contaminated with Candida albicans (30) and Bacillus subtilis (30) for 15 minutes. Next, specimens were divided into Control Group (Group 0) and Test Group (T) for each studied microorganism. The antimicrobial ef...

Soft denture liners are used in complete and partial removable dentures to distribute functional loads homogeneously on the denture-bearing tissues. These materials are recommended in cases of irregular bone resorption, bony undercuts, thin atrophic mucosa, immediate prosthesis, healing after implant placement, and for patients with bruxism and xerostomia. The resilient lining materials can be ...
