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...

There is a great challenge in the treatment of deeply fractured and un-restorable teeth among dentists. Orthodontic force eruption is a method of treatment for these teeth to preserve natural root system and periodontal structures. This technical report is a new modification of this procedure presented in an 11- year old boy with deeply fractured left second mandibular incisor. The fractured te...

AIM To confirm whether implanting pedicle-screw at the level of fractured vertebra increases adverse effects on fracture healing. MATERIAL AND METHODS CT follow-up was conducted for 28 patients who sustained thoracic or lumbar burst fracture and underwent posterior pedicle-screw instrumentation and reduction including implanting screws into the fractured vertebra at the same time. The time fo...

Implant fracture is one of the important biomechanical complications which can present with a considerable problem to the patient as well as the dental surgeon. The aim of this case report is to describe the management of a case of fractured endosseous dental implant in premolar region and microscopic evaluation of the fractured implant segment using scanning electron microscopy. In most of suc...

we have already shown that low intensity pulsed ultrasonic treatment increases rabbit radial fracture healing. the present experiment was undertaken to find out the best duration for treatment. a complete transverse fracture was made in the right radial bones of21 adult male rabbits by a stanley knife. the animals were divided into 4 groups: group 1, control groups 2, 3, and 4, experimental gro...

The reassembly of fractured 3D objects is a critical problem in computational archaeology, and other application domains. An essential part of this problem is to distinguish the regions of the object that belong to the original surface from the fractured ones. A general strategy to solve this region classification problem is to first divide the surface of the object into distinct facets and the...

AIM The aim of this study was to determine the incidence of fracture of ProFile 0.4 and 0.6 taper Series 29 nickel-titanium instruments with respect to operator experience. METHODOLOGY A total of 125 simulated root canals in resin blocks with the same geometrical shape in terms of angle and radius of curvature and coronal and apical orifice diameter were used. Five operators prepared all the ...

  Background: Previous anatomic and radiological studies have described the relationship of the clavicle to major neurovascular structures in healthy subjects. We were curious about this relationship in patients with a clavicle fracture and if it is different from non-fractured clavicles.   Methods: We retrospectively identified all patients with a clavicle fracture between July 2001 and Octobe...
