The purpose of this study was to compare the effects of a differently designed functional appliance (the R-appliance) with a twin-block (TB)-treated group. Thirty patients (18 girls and 12 boys) with a mean age of 10.5±0.7 years were treated with the R-appliance for 16.2±0.3 months and 25 (11 boys and 14 girls) with a mean age of 11.2±1.3 years with a TB for 16.1±1.4 months (control). All had a...

The aim of this study was to evaluate the change in mandibular position during a two-phase orthodontic treatment of skeletal Class II malocclusion. Thirty consecutively treated Chinese male adolescents who had undergone two-phase treatment with Herbst appliance and fixed appliance and fulfilled the specific selection criteria were sampled. Cephalograms taken at T0 (before treatment), T1 (at the...

The benefits of an investment in an energy efficient durable good depend on the life of the investment. If the expected length of ownership is mis-estimated, this will bias calculations of the benefits of energy efficiency, including estimates of the energy efficiency gap. This paper estimates how expected ownership length affects household appliance choices. I leverage the fact that some types...

Abstract Whip spiders (Amblypygi), as their name suggests, resemble (Araneae) in some aspects, but differ from them by heart-shaped (prosomal) dorsal shield, prominent grasping pedipalps, and subsequent elongate pair of feeler appendages. The oldest possible occurrences whip spiders, represented cuticle fragments, date back to the Devonian (c. 385 mya), (almost) complete fossils are known Carbo...

BACKGROUND The mechanisms of action of oral appliance therapy in obstructive sleep apnoea are poorly understood. Videoendoscopy of the upper airway was used during wakefulness to examine whether the changes in pharyngeal dimensions produced by a mandibular advancement oral appliance are related to the improvement in the severity of obstructive sleep apnoea. METHODS Fifteen patients with mild ...

This study compared the effects of 2 treatment protocols for correcting Class II disharmony. The first phase of treatment consisted of functional jaw orthopedics with either the Twin-block or the stainless-steel crown Herbst appliance; the second phase consisted of comprehensive fixed-appliance therapy in both protocols. Each of the 2 samples comprised 28 consecutively treated Class II patients...

SUMMARY The aim of this study is to describe a novel approach to revise maladaptive soft-tissue contour around an ileostomy. A patient with permanent ileostomy suffered from significant defects in soft-tissue contour due to scarring and wound contraction. He underwent autologous fat grafting to achieve sealing of his stoma appliance and improve cosmesis. Due to numerous surgeries, the stoma app...

We report from an ethnographical study of mobile service technicians at Telia Nära examining the process of travelling as a mobile activity, for the purpose of designing for new mobile IT use. Taking a point of departure from information appliance as a vision for designing information technology and activity theory as a framework for grasping activities in context elaboration is made upon how t...
