In this paper we investigate the relation between lateral crossbite disorders and the sounds generated by the Temporomandibular Joint (TMJ). TMJ vibrations are recorded clinically by palpation and auscultation and also electronically by accelerometers. TMJ signals are filtered, amplified, digitized and stored on a computer. Based on joint time-frequency moments calculated from evolutionary spec...

Introduction: Temporomandibular joint (TMJ) disorders are among the most prevalent abnormalities of the jaw, which affect the masticatory system, including the muscles, TMJ, and tendons. Clinical examination alone cannot determine the cause of temporomandibular disorder (TMD). In most cases, the cause of TMD and a proper treatment plan are determined based on imaging modalities. The present stu...

INTRODUCTION Temporomandibular disorder is an umbrella term for various clinical problems affecting the muscles of mastication, temporomandibular joint and associated structures. This disorder has a multifactor etiology, with oral parafunctional habits considered an important co-factor. Among such habits, sleep bruxism is considered a causal agent involved in the initiation and/or perpetuation ...

In classical Von Recklinghausen neurofibromatosis (Type I), skeletal defects occur as a result of abnormalities of derivatives of the neuroectoderm and mesoderm. Temporomandibular joint (TMJ) disorders caused by neurofibroma in the joint capsule or disc have not been reported previously in the English language literature. A case of neurofibroma in the TMJ articular disc in a 29-year-old woman w...

background and objectives : temporomandibular disorder (tmd) refers to chronic pain of the temporomandibular joint (tmj) associated with headache, neck pain, shoulder pain or back pain. the origin of these pains may be related to tmd. many patients with chronic headache undergo different treatments for long periods of time with no cure. these headaches can be treated with proper diagnosis. this...

Purpose: Using simultaneous multi-cross sectional imaging, four cross sections, including the mandibular midline and the right and left temporomandibular joints, were imaged to observe one movement of mouth opening and closing and analyze the movement of the mandible and temporomandibular joints. Materials and Methods: Four cross sections, including the midsagittal section of the mandible, the ...

Linear measurements of passive mandibular border positions and angular measurements of passive opening were recorded in a group of patients with craniomandibular disorders. The relationships between signs and symptoms of craniomandibular disorders and abnormal capacity of movement were studied. There was significant association of some signs and symptoms related to the temporomandibular joint a...

Congenital temporomandibular joint (TMJ) diseases are very rare disorders and are usually diagnosed in childhood. Developmental disorders of the TMJ such as hypoplasia, hyperplasia, and aplasia of the TMJ compartments are characterized by TMJ dysfunction. In childhood, these patients experience recurrent dislocation, pain, and malocclusion. We present the case of a 25-week fetus with unilateral...
