OBJECTIVES The purpose of this study was to evaluate changes in the pharyngeal airway space and hyoid bone position after mandibular setback surgery with bilateral sagittal split ramus osteotomy (BSSRO) and to analyze the correlation between the amount of mandibular setback and the amount of change in pharyngeal airway space or hyoid bone position. MATERIALS AND METHODS From January 2010 to F...

The present experimental work analyzes the development of different mandibular units and its likely impact on the direction of mandibular displacement during facial development, and the relation between the mesiodistal dimension of the first, second, and third molars and the length of the mandibular corpus in a model of protein undernutrition with muscular atrophy in growing rats. Sixteen Wista...

Displacement of bone graft particles during their placement, neck flap closure, and insertion of the freeze-dried mandibular crib housing the graft to the glenoid fossa is a commonly encountered problem during major mandibular reconstruction with autogenous particulate cancellous bone and marrow. Autologous fibrin adhesive proved to be a solution as demonstrated in a series of 33 cases. In addi...

healthy 58-year-old woman had undergone arthrosopy of both temporomandibular joints because of ilateral mandibular clicks and recurrent episodes of aw block that did not respond to nonsurgical treatent. The preoperative examination showed general estriction of mandibular motility (maximal oral aperure 26 mm, right and left lateral deviation 11 and 8 m, respectively, protrusion 10 mm, and dental...

INTRODUCTION Zygomatico-coronoid interference is a rare type of mandibular extracapsular ankylosis. There is a lack of information on the treatment of these cases in the literature. Condylectomy and coronoidectomy are not always the best options for the treatment of limitations in mandibular movement. CASE PRESENTATION A 51-year-old woman presented with mouth-opening limitation due to zygomat...

This paper describes an exceptional case of an enormous complex odontoma affecting the mandibular symphysis of a 9-year-old boy. Because of its dimensions, the lesion produced cortical bone expansion, dental displacement and impactation, which are clinical signs very seldom described for odontomas. The lesion was surgically excised in a conservative way using an intraoral approach with local an...

An effective morphometric method (thin-plate spline analysis) was applied to evaluate shape changes in the craniofacial configuration of a sample of 23 children with Class III malocclusions in the early mixed dentition treated with rapid maxillary expansion and face mask therapy, and compared with a sample of 17 children with untreated Class III malocclusions. Significant treatment-induced chan...

STATEMENT OF PROBLEM The optimal method of implant support for a single mandibular molar crown is controversial because commonly used, threaded, root-form implants developed by Branemark were not originally designed to support individual crowns. PURPOSE The purpose of this study was to develop a finite element model of a single mandibular first molar crown supported by (1) a standard 3.75-mm-...

AIM To conduct an epidemiological study and find the prevalence of some transverse anomalies of occlusion in children aged 7-17 years from the region of Plovdiv; to determine the most appropriate time for early orthodontic treatment based on the results of the study. MATERIAL AND METHODS The study included 883 children from Plovdiv (7-17 years old). The children were studied by means of extra...

The aim of this study was to compare the effects of mucosal thickness on the stress pattern around implants and movement of implant-supported overdentures with ball/female and three different types of magnetic attachments. After insertion of two root-form implants into a mandibular model, the surface of the model was covered with a 1.5- or 3-mm layer of impression material to simulate the oral ...
