  • Examination of the adhesion of polymer composite films based on Bis-GMA/TEGDMA on different metal substrates
    Savez inženjera i tehničara Srbije, 2018
    Co-Authors: Tomić Nataša Z., Algellai Ahmed A., Vuksanović Marija M., Trifunović Dejan D., Dimitrijević Silvana B., Obradović-Đuričić Kosovka D., Jančić-heinemann Radmila M.
    Abstract:

    The subject of this study is the quantitative adhesion of a UV-curing composite film based on Bis-GMA (Bisphenol A glycidylmethacrylate) / TEGDMA (triethylene glycol dimethacrylate) as a matrix and particles doped with ferrous oxide on a metal substrate. Two different metal substrates: silver and gold-spattered brass with nickel Intermediate Coating were used in adhesion evaluating. Adhesion was measured using micro-identation and it was compared with the measured wetting angle of composites to the substrate. It has been shown that the substrates, although with similar mechanical properties that are reflected in very close hardness values, differ by achieved adhesive bonding with the polymer UV-cured polymer film. The addition of ceramic particles in the polymer matrix increased the adhesion of the composite film to both substrates, but the adhesion trend was dependent on the substrate type

Dodatak keramičkih čestica u polimernu matricu dodatno je povećao adheziju kompozitnog filma na obe podloge, dok je trend adhezije u zavisnosti od tipa podloge održan

  • the influence of sio2 and sio2 tio2 Intermediate Coatings on bond strength of titanium and ti6al4v alloy to dental porcelain
    Dental Materials, 2009
    Co-Authors: Jaroslaw Bieniaś, Anna Stoch, Halina Matraszek, Barbara Surowska, Mariusz Walczak
    Abstract:

    Abstract Objectives The purpose of this study was to evaluate the bond strength of commercially pure CPTi and Ti6Al4V alloy with SiO 2 and SiO 2 –TiO 2 Intermediate Coatings to Triceram low-fusing dental porcelain. Methods The multilayered systems were characterized from the standpoint of microstructure analysis (SEM), the mode of failure, the nature of bonding and the influence of Intermediate Coatings on the improvement of bond strength. The SiO 2 and SiO 2 –TiO 2 Intermediate Coatings were applied on the substrate materials by the sol–gel dipping technique. The metal–ceramic bond strength was investigated according to ISO 9693 standards using the three-point flexure bond test. Results Statistically significant higher bond strength of the metal–porcelain for Ti6A14V alloy (28.24 MPa), Ti6Al4V/SiO 2 (32.17 MPa) and Ti6Al4V/SiO 2 –TiO 2 (36.09 MPa) was noted in comparison to CPTi (23.04 MPa), CPTi/SiO 2 (27.98 MPa) and CPTi/SiO 2 –TiO 2 (28.84 MPa), respectively. The nature of metal-Intermediate Coating–porcelain bonding was both mechanical and chemical. The failure in all systems was cohesive and adhesive, mainly adhesive. Significance The application of SiO 2 and SiO 2 –TiO 2 Intermediate Coatings, produced by the sol–gel method, to both CPTi and Ti6Al4V alloy significantly improves the bond strength of metal–porcelain systems in comparison to the metal substrate only after sandblasting, and may have clinical use.
