The purpose of this study was to determine the friction coefficients and wear rates of six commercially available dental ceramics including IPS Empress 2 (E2), Cergo Pressable Ceramic (CPC), Cercon Ceram (CCS) and Super porcelain EX-3 (SPE). Bovine enamel (BE) was also tested as a reference material for comparison purposes. Samples of the dental ceramics were prepared according to the instructions described by the manufacturers in disk-shape with nominal dimensions of 12 mm x 2 mm. The wear tests were performed by means of a pin-on-disk type tribometer. The friction coefficients and specific wear rates of the materials were determined at a load of 10 N and rotating speed of 0.25 cm/s without lubrication. Surface morphology of the wear tracks was examined using a scanning electron microscope. Statistical analyses were made using one-way ANOVA and Turkey's HSD (P < 0.05).

Tensile Bond Strength of a Highly Cross-Linked Denture Tooth to the Compression-Molded and Injection-Molded Denture Base Polymers DOĞAN, ARİFE; Korkmaz, Turan; DOĞAN, ORHAN MURAT; Keskin, Selda; DEMİR, HAKAN (Informa UK Limited, 2009-01-01) This study compared tensile bond strengths between conventional compression-molded heat (HC)-, auto (AP)-, and microwave-polymerized (MC) poly(methyl methacrylate)-based denture resins and a relatively new injection-molded, microwave-polymerized polyurethane based resin (MI) bonded to a highly cross-linked denture tooth. In the first part of the experiments, denture teeth were used as received. In the second part, they were treated with dichloromethane to see its effect on bonding of conventional denture ba...
Mechanical properties of soft liner-poly(methyl methacrylate)-based denture material Usanmaz, Ali; Latifoglu, MA; Dogan, A; Akkas, N; Yetmez, M (Wiley, 2002-07-18) In this study, the mechanical properties of two different permanent soft lining materials and their bonding to poly(methyl methacrylate) (PMMA) were compared. Both of the soft liners were heat-cured commercial materials. The polymerization was carried out by conventional methods suggested by manufacturer, and the curing was done at the temperature of boiling water for 5, 15, 25, and 35 min. The sample groups were tested in the computer-aided tensile-testing machine at a rate of 2 mm/min. The slow rate helps...
Combined effects of ALS and SLS on Al2O3 reinforced composite nickel coatings Yılmaz, Olgun; Karakaya, I. (Informa UK Limited, 2020-05-03) The mechanical and tribological properties of electrochemical coatings can be enhanced by the embedded second phase particles to nickel matrix. Two different anionic surfactants sodium dodecyl sulfate and ammonium lignosulfonate were used together to adjust the wetting conditions and provide the suspension of Al2O3 particles in a nickel sulfamate electrolyte in this study. The effects of current density and amounts of the two surfactants on wear rate, coefficient of friction, and hardness were studied. It w...
Thermal and dynamic mechanical properties of microwave and heat-cured poly(methyl methacrylate) used as dental base material Muhtarogullari, IY; Dogan, A; Muhtarogullari, M; Usanmaz, Ali (Wiley, 1999-12-13) In this study, the particle size distribution, molecular weight, thermal analysis (TGA) differential scanning calorimetry (DSC) and thermogravimetric analysis, and dynamic mechanical analysis (DMA) of poly(methyl methacrylate) used as dental base material were investigated. The commercial raw material used were prepared for microwave curing, and they were cured by microwave and conventional heat methods. The average particle size of the powder studied (103.1 mu m) were much larger than that of the commercia...
Effects of Different Denture Cleansers on the Tensile Bond Strength of Denture Liners DEMİR, HAKAN; SOYGUN, KORAY; Bolayir, Giray; DOĞAN, ARİFE; Keskin, Selda; DOĞAN, ORHAN MURAT (Informa UK Limited, 2009-01-01) The effect of two denture cleansers (Polident (R) and Protefix (R)) on the tensile bond strength between four soft liner materials (Molloplast B (R), Permaflex (R), Sofreliner Tough Medium (R), and GC Reline Soft (R)) and a conventional denture base resin was investigated. For each of the liner materials 35 test specimens were prepared according to test the requirements and assigned into seven groups (n=5). Before tensile testing, five of the liner specimens were kept in water or soaked in two cleansing sol...
