objective(s): occlusal trauma is one of the most common forms of oral biting dysfunction. long-term occlusal trauma could weaken the stomatognathic system; especially damage one’s masticatory muscle. through using the rat model, this study investigated the trophic effect of ciliary neurotrophic factor (cntf) on injured masseter muscle. materials and methods: male wistar rats (n=36) were randoml...

A more refined diagnosis tends to be based on subtle signs and symptoms, requiring the specialist to be extremely judicious and knowledgeable. Occlusal trauma should be included in the differential diagnosis of apical periodontitis and dental trauma. Ideally, when a tooth presents with pulp necrosis and signs of occlusal trauma, one should conduct the interview and diagnostic tests in search of...

Trauma from occlusion is defined as injury to the supporting structures of the teeth from occlusal forces which exceed the reparative capacity of the attachment apparatus. It is of two types. Primary occlusal trauma, where the cause of tissue changes in the supporting structures of the teeth are the occlusal forces. Secondary occlusal trauma, where the tissue support to the tooth is compromised...

Elimination of lesions diagnostic of trauma from occlusion is an essential part of complete periodontal therapy and restoration of health in the masticatory system for such patients. This can be achieved by orthodontic treatment, temporary splinting, bite-planes, occlusal adjustment and permanent splinting of teeth. Occlusal therapy may be required during periodontal treatment for trauma from o...

The diagnosis of occlusion-generated disorders of the dento-maxillary apparatus represents a sensitive stage within the establishment of the therapeutic means for the functional rehabilitation of dental arches. The laborious effort carried out in order to specify the diagnosis resides in the fact that any trauma arising at the level of any component of the stomatognate system may lead to an occ...

OBJECTIVE To determine the association of high occlusal force (HOF) with the signs of occlusal trauma and periodontal conditions in periodontitis patients, and elaborate the relevant clinical implications. METHODS Periodontal parameters and signs of occlusal trauma were recorded for 807 teeth in 30 subjects with untreated chronic periodontitis. The T-scan II occlusal analysis system determine...

or those patients with moderate-tosevere periodontal disease, tooth mobility can contribute to discomfort when eating and decreased masticatory and occlusal function. Tarnow and Fletcher described the indications and contraindications for splinting periodontally involved teeth.1 They stated that the rationale for splinting teeth should include the severity of periodontal disease as determined b...

The mechanisms of tissue changes induced by occlusal trauma are in no way comparable to orthodontic movement. In both events the primary cause is of a physical nature, but the forces delivered to dental tissues exhibit completely different characteristics in terms of intensity, duration, direction, distribution, frequency and form of uptake by periodontal tissues. Consequently, the tissue effec...
