ABSTRACT Objective: The aim of this study was to compare the stress distribution in internal tapered connection implants with different adaptation geometries submitted oblique load simulation using Finite Element Analysis (FEA) method. Methods: Three implant-abutment assemblies were modeled by varying only diameter abutment body cone region. dimensions 4.0 mm and 13 length. Oblique loads 210 N ...

side weirs are flow diversion devices that are widely used in irrigation, drainage and urban sewage systems. the present study focuses on the investigation of the effect of oblique side weirs on the discharge coefficient of a side weir under subcritical flow condition in rectangular channels. in this study 106 laboratory tests were conducted and the results were analyzed to find out the influen...

purpose : we describe clinical and radiologic findings and surgical outcome of an orbital dermoid cyst located in the superior oblique muscle tendon. this unusual location for dermoid tumors has not been reported previously. case report : a 15-year-old girl referred to us with an orbital mass in superonasal quadrant of the left orbit reportedly to be present from birth. computed tomography reve...

abstract background: several studies have examined the reflex response of ankle musculature to sudden inversion in noninjured and injured subjects. to date, there have been no studies to determine the effect of versatile degrees & conditions of perturbation on the ankle musculature latency. the purpose of this study was to measure and determine whether there was a difference in ankle musculatur...

PURPOSE The purpose of this study was to evaluate the effect of differences in the retainer design on load on abutment teeth and displacement of the denture base in mandibular unilateral extension base partial removable dental prosthesis to determine the optimum design for a mechanically appropriate retainer. METHODS Three models were used. Each incorporating a removable denture with differen...

The experimental method of caustics was used for the evaluation of the stress-singularities created by concentrated oblique load applied at the apex of a wedge or on the horizontal straight boundary of a half-plane. The wedge was considered to be elastic, isotropic and under generalized plane stress conditions. According to the method of caustics, the light rays impinging normally at the thin p...

BACKGROUND Despite that a mid-third simple transverse femoral shaft fracture has been traditionally treated with an unlocked reamed intramedullary nail, recently a static locked reamed intramedullary nail has been favored by some orthopedists to avoid missing extended fracture lines. A prospective comparison of both nails was conducted to investigate the superiority between the nails from biome...
