Problems solved by technology

[0007] According to the dental facebow described in Patent Document 4, compared with conventional methods, it is possible to easily reproduce a near-ideal occlusion in a short time. At the same time, it is not easy to align the mouthpiece as the occlusal reference piece installed on the rotating and moving frame with good accuracy to the patient's inherent occlusal surface, and there are still problems that require the skill and labor of technicians

Abstract

The objective of the present invention is to provide a zero moment adjuster capable of reproducing simply and accurately an occlusal curve specific to a patient, within the oral cavity, and which is more convenient to use. The zero moment adjuster according to the present invention is provided with: a base frame 11; face-bow attachment portions 12A, 12B; a face-bow 13; a mouthpiece 14; a securingmeans 15 which can be attached to and removed from one of the face-bow attachment portions 12A to secure the face-bow 13 to the face-bow attachment portions 12A, 12B with a prescribed attachment angleTheta 3; an earpiece attachment portion 16; an earpiece 17; a pad portion 18; and a reference point indicating tool 19 for indicating an occlusal force concentration part N. The mouthpiece 14 is formed in the shape of a curved surface along an occlusal spherical surface centered around a point on an occlusal line which passes through the occlusal force concentration part N and is parallel to sideframes 11a, 11b, and the prescribed attachment angle Theta 3 is an angle designed such that the mouthpiece 14 is located on an occlusal curved surface C in the oral cavity.

Description

technical field [0001] The present invention relates to a zero-moment regulator (also known as an occlusal bend tester, an occlusal contact position tester), and more particularly, to a dental treatment suitable for malocclusion, edentulousness, multiple tooth defects, etc. zero torque regulator. Background technique [0002] In denture base treatment and implant treatment for edentulous, multiple tooth defects, etc., it is extremely important to obtain an ideal occlusion of dentures and bridges. In the past, when providing an occlusion, corresponding to the anatomical form of the oral cavity and perioral predominant, hard tissues, with several imaginary reference lines, planes, to capture the common masticatory movement of the mandible. In addition, in actual treatment, doctors and technicians reconstruct each patient's occlusion based on such ordinary mastication movements. [0003] The reconstruction of the occlusion of each patient by the above-mentioned doctors and te...
