Title:
APPARATUS FOR ISOLATING MOLAR TO FIX JAW JOINT
Document Type and Number:
Japanese Patent JPH02243139
Kind Code:
A
Abstract:
PURPOSE: To accurately reproduce a record in the non-contact state of the teeth for centering the joint position of a lower jaw by the method wherein a device consists of a synthetic resin, and the thickness of the section of a front portion to be introduced between incisive teeth is formed so as to be reduced toward the front end by a bow-shaped member. CONSTITUTION: This device comprises the section of a front portion 10A to be introduced between the upper and lower incisive teeth of as patient and a bow-shape member 10 having the section of a rear portion 10B as a holding member, and the vertical main axis A and horizontal main axis B of the section of the front portion are formed to reduce toward the front end. The patient's head is inclined rearward at approximately 45 deg. angle for making the patient's tooth to be a non-contact state, and the device is set between the incisive teeth of an upper portion by the inclining angle of appropriately 40-60 deg. at adjacent to the marks of 3mm or 4mm of an upper surface, and the upper surface of the section of the front portion is contacted to the interior of the incisive tooth of the upper portion, and the incisive tooth of a lower jaw is slowly contacted to the lower surface of the device. And if any contact is not caused when the device is slightly bitten by the incisive tooth, the device is slowly drawn out in the degree of a posterior tooth being slightly isolated. Consequently, the isolated distance of the incisive teeth can be read by a scale, at the same time the reproducibility becomes more better.
