This study investigated adhesive forces and flexural strength of acrylic resin denture base relined with Molloplast-B soft lining material. To increase bonding between the two materials, the surface of the resin was modified with ultraviolet (UV) irradiation or nitric acid treatment. The peel strength greatly increased with nitric acid treatment because of the high polarity on the poly (methyl methacrylate) (PMMA) surface and the increase in the surface roughness, whereas low peel strength was seen with the UV treatment of the PMMA surface. Although both types of the surface pretreatment increased the flexural strength of PMMA-reline composites compared with the control and bulk PMMA groups, the increase in the UV-treated group was found to be higher than that of the nitric acid treated group.

Bond strength of a silicone soft lining material to poly(methyl methacrylate) resin treated with maleic anhydride and its terpolymers Turgut, Mehmet; Bolayir, Giray; Dogan, Orhan Murat; Keskin, Selda; Dogan, Arife; Boztug, Ali (Informa UK Limited, 2007-01-01) This study investigated the effectiveness of surface treatment of Poly (methyl methacrylate) (PMMA) denture base resin on tensile bond strength between PMMA/silicone-based soft liner. A total of 25 specimens were fabricated and assigned into five groups (n = 5). The surfaces of PMMA were treated with maleic anhydride, maleic anhydride-styrene-vinyl-acetate, n-butylmaleate-styrene-vinyl-acetate, or n-pentamaleate-styrene-vinyl-acetate prior to Primo adhesive primer application and silicone liner placement.

Evaluation of laser treatment on reline-base composites Bolayir, Giray; Turgut, Mehmet; Hubbezoglu, Ihsan; Dogan, Orhan Murat; Keskin, Selda; Dogan, Arife; Bek, Buelent (Informa UK Limited, 2007-01-01) The effects of different laser treatments on some mechanical properties of acrylic resin and soft liner were investigated. A total of 60 test specimens were fabricated according to test requirements. The specimens were roughened with Potassium-ticanyl-Phosphate (KTP), Er:YAG, and Nd:YAG lasers before application of soft liner. The flexural, peel, and tensile bond strengths were measured using a universal testing machine. Fourier transform infrared spectroscopy with attenuated total reflectance (FTIR-ATR) sp...
Microtensile Bond Strength of Self-Adhesive Resin-Based Dental Cement to Bleached Enamel Tamam, Evsen; Keskin, Selda; Ucatasli, Mine Betuel (Informa UK Limited, 2010-01-01) This study investigated the effectiveness of bleaching agents on the micro tensile bond strength (mu TBS) of self-adhesive luting cement and enamel. A total of 126 samples were prepared from the labial surfaces of permanent human maxillary central incisors and assigned into three groups with 42 samples each as: control, enamel bleached with 10% hydrogen peroxide (HP), and enamel bleached with 10% carbamide peroxide (CP). Rely X Unicem (R) (3 M, ESPE) was used as self-adhesive resin cement. The total testing...
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...
