  • The Adhesive Strength and initial viscosity of denture Adhesives
    Acta Odontologica Scandinavica, 2014
    Co-Authors: Guang Hong, Maimaitishawuti Dilinuer, Gang Zheng, Xinzhi Wang, Keiichi Sasaki
    Abstract:

    Abstract Objective. To examine the initial viscosity and Adhesive Strength of modern denture Adhesives in vitro. Materials and methods. Three cream-type denture Adhesives (Poligrip S, Corect Cream, Liodent Cream; PGS, CRC, LDC) and three powder-type denture Adhesives (Poligrip Powder, New Faston, Zanfton; PGP, FSN, ZFN) were used in this study. The initial viscosity was measured using a controlled-stress rheometer. The Adhesive Strength was measured according to ISO-10873 recommended procedures. All data were analyzed independently by one-way analysis of variance combined with a Student-Newman-Keuls multiple comparison test at a 5% level of significance. Results. The initial viscosity of all the cream-type denture Adhesives was lower than the powder-type Adhesives. Before immersion in water, all the powder-type Adhesives exhibited higher Adhesive Strength than the cream-type Adhesives. However, the Adhesive Strength of cream-type denture Adhesives increased significantly and exceeded the powder-type dentu...

  • Influence of composition on the Adhesive Strength and initial viscosity of denture Adhesives
    Dental Materials Journal, 2014
    Co-Authors: Guang Hong, Kentaro Hayashida, Takeshi Maeda, Hiroshi Murata, Keiichi Sasaki
    Abstract:

    To investigate the effect of composition on the initial viscosity and Adhesive Strength between denture Adhesives and the denture base. Two types of water-soluble polymers (methoxy ethylene maleic anhydride copolymer [PVM-MA] and sodium carboxymethyl cellulose [CMC]) were used. Samples were divided into three groups. Group 1 contained only PVM-MA; Group 2 contained only CMC; and Group 3 contained PVM-MA and CMC. The initial viscosity and Adhesive Strength were measured. For Group 1, the initial viscosity increased significantly as PVM-MA content increased. The Adhesive Strength of Group 1 lasted longer than Group 2. The Adhesive Strength of Group 3 varied greatly. The ratio of CMC and PVM-MA has a significant effect on the initial viscosity and Adhesive Strength of denture Adhesives. Our results suggest that it is possible to improve the durability of a denture Adhesive by combining different water-soluble polymers.

  • The Adhesive Strength Test (AST): A Newly Developed Test for Measuring Adhesive Strength of Sealant between Joints of Concrete Pavement
    Journal of Materials in Civil Engineering, 2014
    Co-Authors: Qiang Li, Raphael Crowley, David Bloomquist, Reynaldo Roque
    Abstract:

    A new Adhesive Strength Test (AST) was developed to determine the Adhesive Strength of joint sealant. A series of sealant thicknesses, displacement rates, and curing times were tested to determine proper AST testing parameters using self-leveling (SL) and non-self-leveling (NS) silicone sealants. A series of tests were conducted under varying moisture conditions. Results appeared to indicate that moisture may reduce Adhesive Strength. Drying-time tests were conducted to determine the approximate appropriate “wait-time” between joint washing and sealant installation for 3.2 mm (1/8 in.) and 9.5mm (3/8 in.) joints. A series of tests were also conducted on artificially aged sealants, which appeared to indicate that oven-aging reduces Adhesive Strength for SL sealant. NS sealant, on the other hand, appeared to be largely unaffected by oven-aging. Hot-water aging and freeze-thaw aging appeared to reduced Adhesive Strengths for both sealant recipes.
