BACKGROUND Healing of an anterior cruciate ligament graft in a bone tunnel occurs by formation of fibrous scar tissue, which is weaker than the normal fibrocartilaginous insertion. HYPOTHESIS We hypothesized that a magnesium-based bone adhesive would improve tendon-to-bone healing in a rabbit anterior cruciate ligament reconstruction model. STUDY DESIGN Controlled laboratory study. METHOD...

Nowadays, adhesive joints are largely applied in the automotive, aircraft and aerospace, civil, naval industries. Although several applications involve flat (plane) adherends, curved play an important role many engineering like civil construction. This work aims to investigate three structural adhesives, ranging from brittle ductile, joggle-lap between carbon fibre reinforced polymer adherends ...

The aim of this study was to evaluate the influence of a low-viscosity bonding resin applied over a self-etching adhesive system on the microtensile bond strength (microTBS) of indirect restorations. Comparisons were made using One Up Bond F (OB) self-etching adhesive system, Single Bond (SB) one-bottle adhesive system and Scotchbond Multi Purpose Plus (SMP) bonding component. Thirty bovine inc...

The tension-tension fatigue behavior of ductile adhesively-bonded double-lap FRP joints was experimentally investigated. An acrylic adhesive, which in the rubbery state at ambient temperature, provided joint ductility. degradation characterized by cyclic energy dissipation, stiffness, creep displacement and self-generated temperature. effects elevated temperature on joints’ static tensile pure ...

The current understanding of the thermo-mechanical response cross-laminated timber (CLT) walls to fire is insufficiently developed. This paper presents results obtained using a novel experimental methodology on fire-exposed CLT under sustained loads. findings demonstrate that global instability likely be dominant failure mode for in fire. Use polyurethane adhesive resulted earlier structural th...

Objective: This study aimed to evaluate the suitability of one specific silorane-based composite for the application as a repair material for different substrates. Materials and methods: Truncated cones of composites fabricated and thermocycled for 6000 cycles to serve as a substrate were made of two commercially available dimethacrylate-based composites (DBC) (Filtek Supreme and Clearfil APX) ...

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(2): 473–479. In this paper the mechanical behaviour of structural two-component epoxy adhesives in T-joints is experimentally investigated. The aim of this study is to analyse t...

Bond failure after rebonding for newly placed brackets can be reduced by appropriate enamel surface treatment. This in vitro study investigated the effect of two enamel surface treatments on the bond strength of metallic brackets in the rebonding process. After debonding the brackets and removing the residual adhesive on the enamel surface of 50 upper premolar teeth, the teeth were divided into...

Enhanced finite elements are elements with an embedded analytical solution which can capture detailed local fields, enabling more efficient, mesh independent finite element analysis. In the present study, an enhanced finite element is applied to generate a general framework capable of modeling an array of joint types. The joint field equations are derived using the principle of minimum potentia...

BACKGROUND Different studies have shown the uncertain effects of thermal cycling (TC) and mechanical load cycling (MC) on the dentin microtensile bond strength (µTBS) of composites. This study designed to investigate the effects of TC and MC on the dentin µTBS of single bond-2. MATERIALS AND METHODS Flat dentinal surface was prepared on 48 sound extracted human third molar teeth, and were bon...
