Results: The sample was composed of 176 patients: single angle fracture (n=47), angle with 1 non-angle fracture (n=118), angle with 2 non-angle fractures (n=10), and bilateral angle fractures (n=1). For all fractures, arch bar MMF was found to have significantly lower malocclusion rates than both manual reduction (2.8% vs 17.5%, p=0.01) and non-arch bar MMF (2.8% vs 13.3%, p=0.04). For patients...

PURPOSE To establish management protocol for mandibular angle fracture, we describe pertinent factors including cause, impacted third molar and recent treatment tendency. METHODS We examined the records of 62 patients who had unilateral mandibular angle fracture. Sixty patients who had open reduction surgery were examined at postoperative weeks 1, 4, 8, 12, and 28. RESULTS Left mandibular a...

This article presents a method for simulation of continuous and discrete fracture parameters distributions in hydrocarbon reservoirs using Sequential Indicator Simulation (SIS) and Sequential Gaussian Simulation (SGS) methods. Fracture parameters including azimuth, dip and density are integrated with the porosity and permeability values determined in the models. Based on this study we have iden...

avulsion injury of the flexor digitorum profundus (fdp) with concomitant fracture of the distal phalanx dorsal base is uncommon. simultaneous avulsion fractures of the insertion of this tendon associated with rupture of the tendon from the bony fragment and combination with dorsal base fracture is very rare and also complicated. a 36- year- old man fell and injured his right little finger. fdp ...

This article describes the independent factors that affect kyphotic angle reduction in the treatment of osteoporotic vertebral compression fractures with kyphoplasty. Between January 2008 and September 2011, one hundred twenty-six patients with a single-level osteoporotic compression fracture who underwent kyphoplasty were evaluated for a minimum of 1 year postoperatively. Nine independent vari...

A large number of natural cracks exist in shale reservoirs, and the presence weakens integrity shale, which is an important factor governing effectiveness gas extraction. In this paper, shales from Lower Cambrian Niutitang Formation northern Guizhou were scanned by electron microscopy, their microstructures selected for digital image processing, uniaxial compression numerical tests conducted on...

Control of the grouting pressure within critical for crack propagation in Ordovician limestone can not only ensure grout penetration length, but also prevent risk creating an artificial water channel. Based on fracture mechanics theory, a formula was proposed to calculate mixed mode I-II cracks limestone. The necessary conditions tilted opening, rationality existing empirical value maximum allo...

Surface movement and deformation with fault differ significantly from that without fault. To explore the mechanism of abnormal surface subsidence induced by instability, mechanical model for slip soil cantilever were separately established when mining in hanging wall footwall. Moreover, based on numerical similarity simulation experiment, difficulty instability was compared analysed. The result...

The purpose of this study was to investigate torque and angle of rotation at fracture of new and used.06 ProFile instruments. ProFile sizes 15 to 40 were tested according to American National Standards Institute/American Dental Association Specification #28. Thirty new and used instruments were tested for each size. An analysis of variance was used to compare the torque and angle of rotation at...

This paper describes the applications of the fractured continuum model to the different enhanced geothermal systems reservoir conditions. The capability of the fractured continuum model to generate fracture characteristics expected in enhanced geothermal systems reservoir environments are demonstrated for single and multiple sets of fractures. Fracture characteristics are defined by fracture st...
