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...

A technique utilizing modified Gates Glidden burs and ultrasonics has recently been advocated to remove fractured instruments from root canals. Varying extents of tooth structure are removed during this procedure, potentially leading to complications. This study evaluated the in vitro and in vivo complications associated with fractured file removal. Fractured instrument fragments were removed f...

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...

We report on numerical simulations of acid erosion in a fractured specimen of Carrara marble. The simulations combine two recent advances in lattice-Boltzmann methodology to accurately and efficiently calculate the velocity field in the pore space. A tracer diffusion algorithm was then used to calculate the distribution of reactants in the fracture, and the local erosion rate was obtained from ...

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...

2.?Treatment of fractured ribs. The usual practice in the Punjab hospitals and dispensaries is to apply a broad roller round the chest. I have seen sometimes great inconvenience to arise from the use of a bandage, pressing on both sides of the chest and limiting the free play of the lungs. In one case dyspnoea was very troublesome. Straps of sticking plaster applied on the whole of the injured ...
