Wood-based composite panels generally are first tested out-of-plane in the primary panel direction followed by the cross panel direction, but rarely edgewise. While most applications use wood-based composites in the flat-wise orientation and only need the out-of-plane properties, there are construction configurations where edgewise properties are needed for improved design configurations. A squ...

BACKGROUND The aim of this study was to evaluate and compare the difference in the level of pain using the visual analog scale (VAS) between cases treated with the edgewise appliance and Invisalign. In addition, the cause of pain and discomfort in the Invisalign cases was identified. METHODS The sample consisted of 145 cases for the edgewise group (EG; n=55), Invisalign group (IG; n=38), and ...

INTRODUCTION The crown Herbst appliance was introduced in the late 1980s because of shortcomings of the banded Herbst. In edgewise Herbst treatment, a fixed appliance is used with the crown Herbst to maximize the skeletal effects of treatment. Treatment response to the edgewise Herbst appliance has not been reported in the literature. Our objective was to investigate skeletal and dental changes...

OBJECTIVE To quantify the three-dimensional moments and forces produced by pretorqued nickel-titanium (NiTi) rectangular archwires fully engaged in 0.018- and 0.022-inch slots of central incisor and molar edgewise and prescription brackets. MATERIALS AND METHODS Ten identical acrylic dental models with retroclined maxillary incisors were fabricated for bonding with various bracket-wire combin...

Vibrations of blade and tower have important impact for wind turbine. This paper presents a active controller design to suppress blade edgewise vibrations under aerodynamic load and gravitational load.Treating the sum of aerodynamic load input in edgewise direction and gravitational load as unknown disturbance input,a stochastic disturbance accommodating control(SDAC) approach is proposed to de...

statement of the problem the aim of this study was to compare the treatment outcome of cl i malocclusion patients treated by two methods, including standard edgewise and mbt. materials and methods thirty subjects (23 boys and 7 girls) with an age range between 14‒19 years were included in each group. the patients had cl i malocclusion and were treated through non-ext strategy. pre- and post-tre...

The Tip-Edge bracket features the first and only archwire slot that offers variable control levels. It’s .022" archwire slot can increase in size to .028" relative to the archwire during retraction yet close back down to .022" to facilitate final finishing. Variable control eliminates the excessive anchorage strain and bite deepening that occurs during retraction with conventional edgewise appl...
