The mandibular or third division of the trigeminal nerve is the largest of the three divisions. It is considered a mixed nerve. That is, like the ophthalmic and maxillary divisions, the mandibular conveys afferent fibers. But unlike the former two divisions, the mandibular also contains motor or efferent fibers to the muscles of mastication, the mylohyoid and anterior digastric muscles, and the tensor veli palatini and tensor tympani muscles. So intimately associated with dentistry, the ...

The object of this study was to determine if the resting muscle activity of TMD patients with measured hyperactivity (EMGave > 2.0 microvolts) could be reduced by the application of ULF-TENS (Ultra-Low-Frequency-Transcutaneous Electrical Neural Stimulation) [(BioTENS) BioResearch, Inc. Milwaukee, WI]. Twenty-nine patients with resting muscle hyperactivity and ten without resting muscle hyperactivity were selected from a series of 124 consecutively diagnosed TMD patients. Electromyographic records were taken bilaterally (with the mandible at rest) from the ...

The purpose of this study was to develop a rabbit model of fibrous adhesions in the joint compartment of the temporomandibular joint (TMJ) without surgical invasion into the joint compartment. A unilaterally elastic force of about 120 grams was applied from the anterior edge of masseteric tuberosity to the posterior part of the zygomatic arch between the masseteric fascia layer and the subcutaneous layer in 14 rabbits. The blocks of nondrawing side TMJ were removed ...

The purpose of this study was to investigate the histology of two small masticatory muscles from females and males of more than 70 years of age. By using immuno- and enzyme histochemistry the muscles were characterized by their fiber types and myosin heavy chain pattern. The observations were compared with similar studies of the masseter and temporalis muscles. Previously the two small muscles have been described based solely upon their gross anatomy. One muscle originates ...

Facial pain and other symptoms of temporomandibular disorders (TMD) are rather common in the adult population. According to clinical studies, psychological factors play an important role in the etiology and maintenance of these symptoms. On the other hand, chronic pain can cause depression. The aim of this study was to evaluate the association between symptoms of TMD and depression in a large population sample of young adults. The study was a part of the 31-year ...

The purpose of this research is to investigate the distinctions relating to Presenting Symptoms and Treatment Outcomes between patients suffering temporomandibular disorder (TMD) as a result of traumatic versus nontraumatic etiology. A geographically diverse cohort of 1,842 patients diagnosed with TMD was investigated with special emphasis placed on the following criteria: 1. The distribution of demographic and symptom characteristics of patients with trauma as an immediate precipitating factor versus those with other nontraumatic etiologies ...

Although orthodontic treatment for the finalization of temporomandibular dysfunction (TMD) patients is often advocated, it represents a risk of failure. Furthermore, in the literature there are few articles that illustrate appropriate orthodontic strategies for the finalization of these patients. In this article the authors suggest a step-by-step clinical procedure in order to: 1. verify the rationale for orthodontic finalization in TMD patients; 2. illustrate the guidelines for correct orthodontic treatment; and 3. suggest a strategy ...
