The PBL (Perfobond Leiste) shear connector has the advantages of high bearing capacity and strong constraint ability; however, traditional weak axis problems, its stiffness is large, resulting in deformation ability. To this end, paper proposes a new type flange triple-web key obtains key’s mechanical properties failure mechanism through push-out test. results show that mode steel plate on web ...

OBJECTIVES This in-vitro study sought to assess the push-out bond strength of a total etch and 2 self-etch bonding systems to intracanal dentin of primary anterior teeth (PAT). MATERIALS AND METHODS Thirty-six primary anterior teeth were randomly divided into 3 groups of 5(th) generation (Single Bond 2), 6(th) generation (Clearfil SE) and 7(th) generation (Single Bond Universal) bonding agent...

Background and aims. The single-cone technique has gained some popularity in some European countries. The aim of the present study was to compare the push-out bond strength of gutta-percha to root canal dentin with the single-cone and cold lateral compaction canal obturation techniques. Materials and methods . The root canals of 58 human mandibular premolars were prepared using modified crown-d...

This paper investigates the joint use of push-out mechanisms with RED-like discarding policies to support service differentiation in the Internet. The efficiency and the degree of differentiation of a Complete Sharing with push-out, a RIO and a RIO with push-out queues are assessed. Results indicate that push-out used jointly with RED-like policies does not improve the performance.

This study evaluated the influence of the cementation system on the regional push-out bond strength and failure pattern of fiber posts to radicular dentin. The roots of 48 extracted human incisors were prepared and divided into 3 groups (n = 16), according to the cementation system: AdperScotchbond Multi-Purpose + resin cement RelyX ARC (SBMP+ARC); Adper SingleBond 2 + RelyX ARC (SB+ARC) and; R...
