Embodiment Construction

[0053] Hereinafter, several embodiments of the present invention will be described with reference to the drawings.

[0054] In this specification, for convenience of description, the X direction, Y direction, and Z direction in the measuring instrument roughly correspond to the patient's left-right direction, up-down direction, and front-rear direction, respectively. In addition, the x-rotation, y-rotation, and z-rotation in the measuring instrument roughly correspond to the patient's rotation around the left-right axis, the up-down axis, and the front-back axis, respectively.

[0055] figure 1 It is a figure which shows the schematic structure example of the measuring instrument 1 which concerns on one Embodiment of this invention. The measuring instrument 1 is attached to the upper jaw (maxilla) A in the oral cavity of the patient, and is a dental measuring instrument for measuring the position and orientation of the upper jaw A relative to the head H of the patient. Usual...

Abstract

The present invention enables simple and accurate measurement of the position and orientation of the jaw in the oral cavity of a patient under dental treatment. This dental measuring instrument is provided with: a mounting fixture to be mounted within the oral cavity of a patient; an arm that is connected to the mounting fixture in such a manner as to extend from the mounting fixture toward the outside of the oral cavity of the patient; and a leading end part provided to the leading end of the arm, wherein the arm can be transformed so as to be capable of changing the position and orientation of the leading end part.

Description

technical field [0001] The present invention relates to a measuring instrument and a measuring method for measuring the position and orientation of a jaw in an oral cavity during dental treatment. This application claims the priority of Japanese Patent Application No. 2019-011339 filed on January 25, 2019, and the contents described in this application are incorporated by reference in this application for designated countries that recognize the introduction of references based on documents. . Background technique [0002] In dental treatment, it is important to accurately grasp the position and orientation of the patient's upper jaw. For example, when the patient's face is viewed from the front, it is desirable that the midline of the front teeth to be repaired (repaired) or corrected be parallel to and overlapped with (centered) the midline of the patient's face. In general, however, the position and orientation of the patient's upper jaw are not perfectly centered with r...
