Five subjects with TMJ dysfunction showed difficulty in making reproducible mandibular border movements as recorded by a pantograph. These subjects were treated with occlusal bite splints, and muscle activity was studied by electromyography. After one month of treatment, most subjects showed relief of clinical symptoms and improved EMG muscular activity.(More)
A study was conducted to ascertain what happens to dysfunction symptoms followed only by occlusal splint therapy. Four hundred eighty-six pantograms were made on 15 experimental patients over a period of 5 months to 1 year. Five control patients were monitored over this same period but received no occlusal therapy. The experimental patients with TMJ(More)
The purpose of this study was to determine the effect of TMJ dysfunction on the recording of centric relation. Centric relation was recorded using an anterior occlusal stop and by bimanual manipulation. Changes in occlusal contacts were recorded before and after occlusal splint therapy in six subjects with TMJ dysfunction. The pantographic reproducibility(More)
The pantographic reproducibility index (PRI) has been developed to quantitate incoordinated mandibular movements; one of the signs and symptoms of TMJ dysfunction. The PRI has been proven valid clinically in controlled research using more than 200 patients and scoring more than 2300 pantographic tracings during the past 10 years. The PRI can be used to(More)
An occlusal scribing device attached to a fully adjustable articulator was used to generate occlusal tracings. The tracings were analyzed to determine the effect changes in progressive side shift and condylar inclination settings had on molar occlusal morphology. The progressive side shift adjustment affected the cusp height and ridge and groove position,(More)
An earlier study of 50 patients with occlusions restored by fixed partial dentures indicated a high percent (68%) of TMJ dysfunction. Occlusal interferences can play a significant role in causing TMJ dysfunction. To determine the significance of occlusal interferences, occlusal splints were placed in 10 of these restored patients who had moderate to severe(More)
An occlusal scribing device attached to a fully adjustable articulator was used to generate occlusal tracings. The tracings were analyzed to determine the effect changes in immediate side shift, intercondylar distance, and rear and top wall settings had on molar occlusal morphology. When ranked from greatest to least effect, a 0.2 mm change in the immediate(More)
