The purpose of this study is to investigate the fit of zirconia cores and all-ceramic crowns prepared with different cervical margin designs. The radius of curvature between the axial wall and the occlusal surface was set to 1 mm in an abutment using the cervical shoulder marginal design (S) and to 0.2 and 0.5 mm in abutments with round shoulders (0.2RS and 0.5RS, respectively). The internal ga...

The present study aimed to characterize the effect of a nearby distractor on vertical, horizontal, and oblique saccade curvature under normal saccade preparation times. Consistent with previous findings, longer-latency vertical saccades showed greater curvature away from a distractor than did oblique or horizontal saccades. At short latencies, vertical saccades also showed greater curvature tow...

Involving the Ricci curvature and the squared mean curvature, we obtain basic inequalities for different kind of submaniforlds of a Sasakian space form tangent to the structure vector field of the ambient manifold. Contrary to already known results, we find a different necessary and sufficient condition for the equality for Ricci curvature of C-totally real submanifolds of a Sasakian space form...

The purpose of this study was to compare the results of 2 surgical strategies for 4-level cervical spondylotic myelopathy: a hybrid procedure using anterior cervical diskectomy and fusion (ACDF) combined with segmental corpectomy versus posterior laminectomy and fixation. Between 2002 and 2010, fifty-one patients with consecutive 4-level cervical spondylotic myelopathy were treated surgically, ...

ABSTRACT Objectives: Evaluate the surgical treatment of scoliotic curvature effects and sagittal radiographic parameters spine upper limbs after with direct vertebral rotation (DVR) associated type 1 osteotomy in adolescents idiopathic scoliosis (AIS). Material Methods: 41 patients AIS were evaluated compared before surgery. Scoliosis was confirmed by a spine. The were: Cobb angles (proximal di...

we evaluated the specific pattern of pre- and postoperative neurological signs and symptoms of cervical spondylotic myelopathy (csm) to determine [mdings which had a predictive value for surgical outcome. consecutive patients with csm caused by osteophytic ridge or intervertebral disc herniation who underwent anterior cervical decompression and fusion in loghman hakim hospital from 1999-2003 we...

[Purpose] To present the case of the dramatic reduction in pain, disability, and neurologic symptoms following the reduction of forward head translation and increased cervical curvature in a patient suffering from post-surgical radiculopathy. [Subject and Methods] A 52-year-old male mechanic presented with chronic neck pain, unilateral paresthesia along the C5 and C6 dermatome distributions and...

The aim of this study is to evaluate the efficacy of hydroxyapatite grafts in multilevel cervical interbody fusion during the one year follow-up. A total of 86 patients with degenerative cervical disc disease underwent all together 224 cervical interbody fusion procedures in which either Smith-Robinson or Cloward type hydroxyapatite grafts were used. The surgeries included radiculopathy in 38 c...
