Imaging of temporomandibular joint: approach by direct volume rendering.

Background: The purpose of this study was to conduct a morphological analysis of the temporomandibular joint, a highly specialized synovial joint that permits movement and function of the mandible.

Materials And Methods: We have studied the temporom-andibular joint anatomy, directly on the living, from 3D images obtained by medical imaging Computed Tomography and Nuclear Magnetic Resonance acquisition, and subsequent re-engineering techniques 3D Surface Rendering and Volume Rendering. Data were analysed with the goal of being able to isolate, identify and distinguish the anatomical structures of the joint, and get the largest possible number of information utilizing software for post-processing work.

The arterial blood supply of the temporomandibular joint: an anatomical study and clinical implications.

Purpose: The aim of this study was to analyze three-dimensional images of the arterial supply to the temporomandibular joint.

Materials And Methods: Ten patients (five men and five women, mean age 36 years) without signs or symptoms of temporomandibular disorders, who underwent contrast-enhanced computed tomographic (CT) scanning with intravenous contrast, were studied. The direct volume rendering technique of CT images was used, and a data set of images to visualize the vasculature of the human temporomandibular joint in three dimensions was created.

Manual therapy of the mandibular accessory ligaments for the management of temporomandibular joint disorders.

Temporomandibular joint disorders are characterized by chronic or acute musculoskeletal or myofascial pain with dysfunction of the masticatory system. Treatment modalities include occlusal splints, patient education, activity modification, muscle and joint exercises, myofascial therapy, acupuncture, and manipulative therapy. In the physiology of the temporomandibular joint, accessory ligaments limit the movement of the mandible.

[Celiac disease and malocclusion].

Celiac disease is an autoimmune disease, caused by a permanent intolerance to gluten, that occurs in genetically predisposed individuals. It causes enteropathy. In these individuals a prolonged exposure to gluten increases the risk of developing other pathologies, which may affect both developing dentition and oral mucosa.

MMP-2, MMP-9, and iNOS expression in human dental pulp subjected to orthodontic traction.

Objective: To test the hypothesis that some metalloproteinases (MMP-2, MMP-9) and inducible nitric oxide synthetase (iNOS) enzymes in dental pulp samples do not vary when subjected to orthodontic treatment.

Materials And Methods: Human dental pulps were taken from male and female patients (N=10; age 10-14 years). A straight wire technique was used with nickel-titanium or steel archwires.

The measurement of craniocervical posture: a simple method to evaluate head position.

Objective: Some studies have correlated craniocervical posture (CCP) with pharyngeal airway space diameter, breathing conditions, neck pain, headache, dentofacial structures and temporomandibular disorders. Several methods have been suggested in an attempt to establish the best way of evaluating head position using teleradiographs and cephalometric analysis. The objectives of this study therefore were to describe a method of measuring the natural head position (NHP) without exposure to radiation or fixture of the cephalostat, and then to test whether there might be a simple method of reproducing this position in the cephalostat to make lateral cephalograms in the study of CCP.

Condylar growth after non-surgical advancement in adult subject: a case report.

Background: A defect of condylar morphology can be caused by several sources.

Case Report: A case of altered condylar morphology in adult male with temporomandibular disorders was reported in 30-year-old male patient. Erosion and flattening of the left mandibular condyle were observed by panoramic x-ray.

The relationship between the stomatognathic system and body posture.

In recent years, many researchers have investigated the various factors that can influence body posture: mood states, anxiety, head and neck positions, oral functions (respiration, swallowing), oculomotor and visual systems, and the inner ear. Recent studies indicate a role for trigeminal afferents on body posture, but this has not yet been demonstrated conclusively. The present study aims to review the papers that have shown a relationship between the stomatognathic system and body posture.

Binocular motility system and temporomandibular joint internal derangement: a study in adults.

Introduction: Ocular convergence defects have been confirmed in adults with temporomandibular joint (TMJ) dysfunction, but few studies of the relationship of the oculomotor apparatus to TMJ disc displacement have been reported. The purpose of this study was to examine the impact of disc displacement on the oculomotor capacity of the eyes in adults.

Methods: Fifty symptomatic patients with bilateral TMJ disc displacement (13 men, 37 women; mean age, 28.

Human temporomandibular joint morphogenesis.

Temporomandibular joint morphogenesis was studied. Ranging in age of fetuses examined was from 6 to14 weeks' gestation. Our results showed the condyle so first element that appear between 6 degrees and 8 degrees week (condylar blastema).
