摘要:
Mandibular closure is produced by simultaneous and even electrical programmed stimulation of the motor nerves controlling the masticatory and facial muscles. The resultant involuntary closure of the mandible is independent of the volition of the patient or the manual guidance of the dentist. The method and techniques associated therewith are useful in a number of clinical and diagnostic techniques.
摘要:
A method of monitoring mandibular movements whereby a permanent magnet is secured to the mandible and one or more fluxgate magnetometers are located relative to the permanent magnet so as to sense changes in magnetic field which result from mandibular movement. The outputs of the fluxgate magnetometers are linearized, if necessary, and then recorded to provide an indication of mandibular movement in one or more planes. The output from the magnetometers may be differentiated by associated electronics to provide an indication of velocity and/or acceleration of the mandible during closure.
摘要:
Electrodes capable of conforming to irregular surfaces include a cup-shaped housing having an open end, a pad of electrically conductive coiled metallic wire in the housing, a felt of porous material over the metallic wire pad, and a mounting ring contacting the wire pad and felt around their circumference to hold the pad and felt in place in the housing. Three electrodes, two input electrodes and a dispersal electrode, of the type described are attached through electrically conductive support members to an adjustable headband. The two input electrodes are pivotally attached to the headband. Lead wires from the output of a pulse generator connect with the electrodes. The lead wires to the input electrodes are run along the surface of the headband and covered with an insulating material.
