Purpose In the treatment of obstructive sleep apnea (OSA), there is not yet a convenient tool for deciding whether mandibular advancement oral appliance (OA) adequately adjusted or when to perform post-treatment sleep-testing. We hypothesized that gradual reduction in STOP (snoring, tiredness during daytime, observed apnea, high blood pressure) score, i.e., fewer Yes responses questionnaire, pa...

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...

abstract background and aim: the aim of the present study was to evaluate the cephalometric changes in class ii division 1 mandibular deficient patients treated with farmand functional appliance.  methods and materials: twenty-seven subjects (17 girls and 10 boys) with the mean age of 11.1±1.4 years were involved in the present study. all the subjects were treated with farmand functional applia...

lthough positive airway pressure (PAP) devices have become the mainstay of treatment for obstructive sleep apnoea, not all patients can or will use PAP on a nightly basis. Many patients find taking a bulky PAP unit on business or vacation trips a burden. In this issue of Thorax Smith and Stradling attempt to show that a simple non-adjustable oral appliance may be used in place of PAP on a short...

A tangible programming interface called ``Push-pin'' is proposed, which involves end-users in designing smart home programs for home appliance automation. Programming on the Push-pin system is based on a stimulus-response model in which an appliance connected to another appliance via a network gets activated when the other appliance is activated. To interconnect two appliances, the user puts a ...

OBJECTIVES The principle of leverage to superpose the convex surfaces of two shells was applied to develop a device for treating limitation of mouth opening and called it the "shell-shaped mouth opener" and analyzed pressure on the teeth with the TheraBite(®) appliance and the shell-shaped mouth opening appliance. MATERIAL AND METHODS To compare the TheraBite(®) appliance and the shell-shaped...

The purpose of this study was to determine whether anterior and inferior displacement of the maxilla seen with rapid palatal expansion when done with a banded rapid palatal expansion appliance is significantly different from an occlusally bonded rapid palatal expansion appliance. It was hypothesized that the bonded appliance would limit unwanted displacement of the maxilla by producing vertical...

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...
