Schwannomas are the most common tumors of the peripheral nerves. Intraosseous schwannoma is a rare entity; approximately 200 cases are described in the world literature, with only 1 involving the ileopubic ramus. To the authors' knowledge, this article is the first to describe a giant intraosseous schwannoma of the ileopubic ramus, its clinical presentation and radiographic aspect, its histolog...

PURPOSE This study was performed to evaluate the reproducibility of panoramic radiographs of dentulous and edentulous patients. MATERIALS AND METHODS The reproducibility of panoramic radiographs was evaluated using the panoramic radiographs acquired from 30 anterior dentulous patients by using a common biting positioning device (dentulous group) and 30 anterior edentulous patients by using ch...

This study pertains to a random sample of untreated French-Canadian adolescents (79 females and 107 males) evaluated at 10 and again at 15 years of age. Superimpositions on natural reference structures were performed to describe condylar growth and modelling of 11 mandibular landmarks. Superimpositions on natural cranial/cranial base reference structures were performed to describe mandibular di...

BACKGROUND Investigate the effect of percutaneous radiofrequency compared to a sham procedure, applied to the ramus communicans for treatment of lumbar disc pain. METHODS Randomized sham-controlled, double-blind, crossover, multicenter clinical trial. Multidisciplinary pain centres of two general hospitals. Sixty patients aged 18 or more with medical history and physical examination suggestiv...

The intralaminar screw construct has been recently introduced in C6-C7 fixation. The aim of the study is to compare the stability afforded by three different C7 posterior fixation techniques using a three-dimensional finite element model of a C6-C7 cervical spine motion segment. Finite element models representing three different cervical anchor types (C7 intralaminar screw, C7 lateral mass scre...

BACKGROUND Numerous condylar repositioning methods have been reported. However, most of them are 2-dimensional or are complex procedures that require a longer operation time and a highly trained surgeon. This study aims to introduce a new technique using a condylar repositioning plate and a centric relation splint to achieve a centric relationship. METHODS We evaluated 387 patients who had un...

To compare the mechanical effectiveness of a new conical screw design with a conventional cylindrical screw design, the screw insertion time, torque, and pull-out strength of single-pedicle screw and triangulated-pedicle screw constructs of each type of screw were compared in human cadaveric vertebral bodies. The time required to insert the conical screws was less than that required for cylindr...

Successful osseointegration of the dental implants requires sufficient bone volume surrounding implant site. The mandibular ramus is considered reliable donor site for reconstructing alveolar ridge defects prior to dental implant placement. The aim of this study was to present the clinical efficiency of using ultrasound surgery for harvesting mandibular ramus bone graft. 20 patients (10 male, 1...

OBJECTIVE To determine the prevalence of impacted mandibular second molar (MM2) and the association between MM2 impaction and crowding. The clinical significance of the angle between first and second mandibular molar and of the space between the first mandibular molar (MM1) and the anterior margin of mandibular ramus in MM2 impaction were also evaluated. MATERIAL AND METHODS In this retrospec...

INTRODUCTION Aneurysmal bone cyst is an expansile, lytic, multiloculated, fluid filled cavities which usually occurs in the metaphysis of the long bones. ABC of the pubic ramus is a rare entity.. CASE REPORT We present a case of a 21 year old male who presented with a swelling of the right inguinal region which was gradually progressive. Radiologically, there was a lytic expansile lesion of t...
