The aim of this study was to investigate the position and course of the mandibular canal through the mandibular ramus using computed tomographic (CT) imaging and to relate the findings to performing sagittal split ramus osteotomies. The mandibles of 35 patients with skeletal Class III prognathism with symmetry (12 males and 23 females) were observed on(More)
Histopathological changes caused by trauma to the rat temporomandibular joint synovium were examined by light microscopy. The trauma was induced by forced hypermobility of the condyle. Pathological changes of the synovium were found primarily in the anterior pouch of the upper joint compartment. The main findings included surface cell proliferation,(More)
This study assessed the relationship between craniofacial characteristics and the size of the pharyngeal airway space (PAS), taking into account head posture. Sixty dental students 25-30 years of age (30 men and 30 women) were examined by lateral cephalometry. The data were corrected with the use of appropriate regression equations for the PAS. The PAS(More)
PURPOSE The purpose of this study was to investigate the distribution of cancellous bone relative to performance of the medial osteotomy of a sagittal split ramus osteotomy using computed tomography scanning. PATIENTS AND METHODS Skeletal Class III patients consisted of 11 males and 22 females with a mean age of 23 years. The control patients without(More)
OBJECTIVE The purpose of this study was to establish and histologically examine the time course of synovitis induced by trauma to the rat temporomandibular joint. STUDY DESIGN Synovitis of the temporomandibular joints of 8-week-old male Wister rats was induced by forced condylar hypermobility, which was administered 10 times successively once a day for 10(More)
A 68-year-old woman received a formocresol pulpectomy of the right lower lateral incisor. The temporary restoration was lost within hours. The next day, the patient suffered continuous pain, the gingiva sloughed, and the alveolar bone was exposed. Four days after treatment, the patient complained of moderate pain. Six days after the pulpectomy, the tooth(More)
PURPOSE To investigate the position of the mandibular condyle at maximal mouth opening in individuals 19 to 30 years of age with no functional disorders of the masticatory system. PATIENTS AND METHODS Measurements were made in 153 subjects (99 men, 54 women), and 41 men and 44 women had transcranial radiographs taken of their right and left(More)
The present study assessed the relationship between disc displacement and facial morphologic features in 48 patients with skeletal Class III malocclusion. Clinical examination, standardized lateral oblique temporomandibular joint radiographs, and cephalographs were used to investigate this relationship. Disc displacement was evaluated by the presence of(More)
