Abstract
The utility model discloses a measuring instrument for the difference value of the clearances of the occlusal surfaces of preparation bodies, which comprises an upper movement body and a base, wherein the upper movement body and the base are connected together by a rotating shaft, a limiting rod is connected to the rotating shaft, the front end of the limiting rod is provided with a bracket, the front end of the bracket is provided with a clearance impression, the end part of the base is provided with a rubber ring, the end part of the upper movement body is provided with a micrometer, the side face of the micrometer is provided with a sleeve body, the front end of the micrometer is provided with a flat plate, and the front end of the flat plate is provided with a rubber ring. According to the measuring instrument for the difference value of the clearances of the occlusal surfaces of the preparation bodies, the difference value between the clearance of the occlusal surface of a model preparation body and the clearance of the occlusal surface of a preparation body in the oral cavity can be measured, the manufacture of a restoration body of a laboratory is directed, the working efficiency of a clinician is enhanced, and the chair-side working time is reduced.
Description
Technical field
This utility model relates to the recovery technique of oral cavity field, especially a kind of preparation body interocclusion crack difference measuring instrument.
Background technology
The Prosthodontics doctor has cognition, and corona interlock on model is normal, but in placely in mouth closes high situation after gritting one's teeth appears in regular meeting, and this is a ubiquitous phenomenon.The appearance of this situation; It mainly is mouthful interior situation of duplicating that plaster model is difficult to entirely accurate; It is tight because of the mouth internal gearing that physiological mobility causes that the nature tooth here mainly is discussed, for seeking a kind of solution greater than the problem in preparation body interocclusion crack in the mouth in preparation body interocclusion crack on the model.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned technical disadvantages a kind of preparation body interocclusion crack omnibearing observation appearance to be provided.
The technical scheme that this utility model technical solution problem adopts is: a kind of preparation body interocclusion crack difference measuring instrument, comprise mobile and base, and saidly attend mobile and base links together through rotating shaft; Be connected with gag lever post in the said rotating shaft; The front end of gag lever post is provided with support, and the front end of said support is provided with the gap die, and the end of said base is provided with rubber grommet; Said end of attending mobile is provided with micrometer; The side of micrometer is provided with body, and the front end of micrometer is provided with flat board, and the front end of said flat board is provided with rubber grommet.
Said gap die is processed by silicone rubber.
The beneficial effect that this utility model had is:
This utility model can prepare the difference between the preparation body interocclusion crack in body interocclusion crack and the oral cavity by measurement model; Instruct skilled worker chamber dummy to make, explicitly call for the skilled worker chamber when corona is made, need fall the numerical value of infraclusion face height, reduce to make error; Reduce doctor's accent tooth resultant; Improve dummy and make precision, improve clinician's work efficiency, reduce the other working time of chair.
Description of drawings
Accompanying drawing 1 is the structural representation of this utility model.
The specific embodiment
Do following detailed description below in conjunction with 1 pair of this utility model of accompanying drawing.
This utility model comprises mobile 2 and base 1, and the said mobile 2 of attending links together through rotating shaft 3 with base 1, is connected with gag lever post 4 in the said rotating shaft 3; The front end of gag lever post 4 is provided with support 10, and the front end of said support 10 is provided with gap die 5, and the end of said base 1 is provided with rubber grommet 6; Said end of attending mobile 2 is provided with micrometer 7; The side of micrometer 7 is provided with body 9, and the front end of micrometer 7 is provided with flat board 8, and said dull and stereotyped 8 front end is provided with rubber grommet 6; Said gap die 5 is processed by silicone rubber.Last mobile, gag lever post, base three parts can be opened around the shaft; Rubber grommet is detachable, does not damage hardware, is beneficial to repeatedly to utilize; Combine closely between micrometer and the flat board, very close to each other, flat board does not rotate with micrometer; A gap die need be changed in gap of every measurement; Reading is vertically to the distance between the contact point the earliest; Die and the model die difference between the two is needed numerical value in mouthful; Support is that draw and insert-type is connected with gag lever post, and the first section can be pulled out, and can sterilize, and inserts one at every turn, and the direction of insertion is restricted, guarantees that direction is constant, and support can accurately insert in the gag lever post accurate with position between the gag lever post like this.
This utility model can be in the tooth preparation process comprehensive observation gap length, instruct tooth preparation.After clinical manipulation is accomplished, in seal is got mouthful respectively with model on the gap die, measure difference between the two after turning over the system formpiston, be exactly that corona gritting one's teeth of need reducing in skilled worker chamber closed height.
Claims (2)
1. preparation body interocclusion crack difference measuring instrument is characterized in that: comprise mobile and base, saidly attend mobile and base links together through rotating shaft; Be connected with gag lever post in the said rotating shaft; The front end of gag lever post is provided with support, and the front end of said support is provided with the gap die, and the end of said base is provided with rubber grommet; Said end of attending mobile is provided with micrometer; The side of micrometer is provided with body, and the front end of micrometer is provided with flat board, and the front end of said flat board is provided with rubber grommet.
