PURPOSE To evaluate the load to failure and the mode of failure of a novel suture anchor construct that does not require knots (the "twist-lock" construct) and to compare it with a standard suture anchor construct (Corkscrew; Arthrex, Naples, FL). TYPE OF STUDY Biomechanical single-pull load-to-failure study comparing the twist-lock construct to the Corkscrew suture anchor construct. METHOD...

Dual-cement resins are composite resins that are both light activated and chemically cured. They can be cured completely with a visible light source or by the catalyst and base reaction of the material. With the. control of setting time, dual cements appear to offer clinicians advantages in orthodontic bonding. The purposes of the present research are to compare various dual cements in regard t...

In this research, after conducting chemical tests on flour samples (moisture, ash, protein, fiber and pH), potato flour and xanthan gum were added to wheat four at levels 5, 10 and 15 percents and 0.5 and 1 percents, respectively, and subsequently production of toast bread in semi-industrial manner was started, Then the qualitative characteristics (Nutritional Value) of toast breads were measur...

This paper investigates the effects of brazing temperatures on microstructure and compressive strength for porous nickel to copper stainless steel using VZ2250 as filler metal. A high vacuum furnace is used braze samples. Three different process parameters were set with a heating cooling rate 10°C/min, respectively. The characteristics joint interface have been investigated evaluate performance...

The objective of this project is to get the energy absorption aluminium honeycomb core through experimental work and simulation analysis. force-displacement behavior absorb are studied for two different cell sizes core, which 0.0127 m 0.01905 m, respectively. out-of-plane dynamic compression tests conducted specimens by using INSTRON CEAST 9340 drop tower machine with an impact mass 25 kg at 80...

The aim of this study was to evaluate the degree conversion (DC) and cohesive strength (CS) two conventional resin cements a self-adhesive cement using different forms activation. Two dual (Variolink II RelyX ARC) were polymerized in three ways activation, namely Chemically Activated (CA), Light with Interposition disc (LI) Light-Activated (L). DC evaluated Fourier Transformed Infrared Spectros...

PURPOSE This study was conducted to examine a biomechanical model and to help answer fundamental questions that relate to rigid plate fixation in the maxilla. Specifically, we sought to elucidate the principal strain patterns generated in the maxilla secondary to masticatory forces as well as the amount of permanent deformational changes incurred due to these loading forces. MATERIALS AND MET...

Stretchability is one of the most important functional properties of Mozzarella cheese, but no objective and widely accepted technique exists for evaluation; most of the cheese stretchability tests are influenced by the ambient conditions. This paper demonstrates a technique, which is novel and relatively simple, to evaluate the stretchability of Mozzarella cheese objectively. In an oil bath, m...

BACKGROUND Acrylic teeth have long been used in the treatment of a complete denture. One of the primary advantages of acrylic teeth is their ability to adhesively bond to the denture base resins. Although the bonding seems satisfactory, however, bond failures at the acrylic teeth and denture base resin interface are still a common clinical problem in prosthodontics. The purpose of this study wa...
