Abstract

The utility model discloses a jaw plane measuring device which comprises a jaw surface gauge body which is provided with an inner mouth part for a patient to bite and an outer mouth part extending out of the mouth of the patient, wherein, the outer mouth part comprises a forepart board arranged in the front side of the patient oral cavity and lateral alar plates extending from both sides to the ear part of the patient, a pupil measuring rod mounting hole corresponding to the position of the eyes of the patient and a nasal ala measuring rod mounting hole corresponding to the position of the nasal ala of the patient are arranged on the forepart board, an ear measuring rod mounting hole corresponding to the position of the ears of the patient arranged on the lateral alar plate, the pupil measuring rod, the nasal ala measuring rod and the ear measuring rod are connected with the jaw surface gauge body in a detachable way. By providing the measuring rods on the jaw surface gauge body, the jaw plane measuring device reduces jaw surface measuring errors because doctors have little clinic experience, thus the work efficiency and the work quality are improved.

Description

Jaw plane survey device

Technical field

This utility model relates to a kind of dental tool, relates in particular to the planar gauge of a kind of jaw.

Background technology

In the complete denture restoration process that the strong section of clinical mouth has a denture made, the planar measurement of jaw is a committed step that is concerning the denture processing success or not, and in clinical practice, the doctor can only rely on the clinical experience of oneself and the ability of range estimation to determine the jaw plane, like this for the few young doctor of clinical experience, planar measurement is a difficult problem to jaw, be easy to because of determining that the jaw plane is inaccurate, after causing complete denture restoration to be finished, be difficult to reach best jaw poised state, change the form of patient's face, seriously also can influence patient's feed.

The utility model content

Technical problem to be solved in the utility model provides a kind of jaw plane survey device, to reduce the few jaw plane survey error that causes of clinical experience owing to the doctor.

For solving the problems of the technologies described above, the technical solution of the utility model is: jaw plane survey device, comprise jaw surface ga(u)ge body, described jaw surface ga(u)ge body has the interior part of the mouth of stinging for patient's rank and stretches out the outer outer part of mouth of patient's mouth, described mouthful of outer part drawn together front panel that is positioned at front side, patient oral cavity and the side wing that extends from two side direction patient ears, described front panel is provided with pupillometry bar installing hole corresponding with the patient's eye pupil position and the wing of nose measuring stick installing hole corresponding with patient wing of nose position, described side wing is provided with the corresponding ear's measuring stick installing hole in position with patient ear, described pupillometry bar installing hole, be respectively equipped with on wing of nose measuring stick installing hole and the ear's measuring stick installing hole with described jaw surface ga(u)ge body removably connects and have a graduated pupillometry bar, wing of nose measuring stick and ear's measuring stick.

As preferred embodiment a kind of, described pupillometry bar installing hole, wing of nose measuring stick installing hole and ear's measuring stick installing hole are through hole, the connecting portion and the described through hole of described pupillometry bar, wing of nose measuring stick and ear's measuring stick are suitable, and described pupillometry bar, wing of nose measuring stick and ear's measuring stick are plugged in respectively on the corresponding through hole.

As preferred embodiment a kind of, described through hole is a rectangular through-hole.

After having adopted technique scheme, the beneficial effects of the utility model are: because described front panel is provided with pupillometry bar installing hole corresponding with the patient's eye pupil position and the wing of nose measuring stick installing hole corresponding with patient wing of nose position, described side wing is provided with the corresponding ear's measuring stick installing hole in position with patient ear, described pupillometry bar installing hole, be respectively equipped with on wing of nose measuring stick installing hole and the ear's measuring stick installing hole with described jaw surface ga(u)ge body removably connects and have a graduated pupillometry bar, wing of nose measuring stick and ear's measuring stick, by the pupillometry bar, whether can judge jaw surface ga(u)ge body plane intuitively parallel with the line of patient's eye pupil, whether can judge jaw surface ga(u)ge body plane intuitively by wing of nose measuring stick and ear measuring stick parallel with patient's ala-tragus line, thereby reduced the few jaw plane survey error that causes of clinical experience, improved work efficiency and work quality owing to the doctor.

Because described pupillometry bar installing hole, wing of nose measuring stick installing hole and ear's measuring stick installing hole are through hole, described pupillometry bar, the connecting portion of wing of nose measuring stick and ear's measuring stick and described through hole are suitable, described pupillometry bar, wing of nose measuring stick and ear's measuring stick are plugged in respectively on the corresponding through hole, thereby it is more convenient to install and measure bar, by the mode of a plurality of ears measuring stick installing hole is set, can regulate the position of ear's measuring stick according to the size of patient's head at any time, make it corresponding, improved the accuracy that the jaw body plane is measured with patient ear position.

Because described through hole is rectangular through-hole, can prevent that each measuring stick of installing from rotating and influence certainty of measurement.

Description of drawings

Fig. 1 is the front view of this utility model embodiment;

Fig. 2 is the vertical view of Fig. 1.

The specific embodiment

Shown in Fig. 1 and Fig. 2 are common, a kind of jaw plane survey device, comprise jaw surface ga(u)ge body 1, described jaw surface ga(u)ge body 1 has the part 11 mouth outer part outer with stretching out patient's mouth in the mouth of stinging for patient's rank, described mouthful of outer part drawn together front panel 12 that is positioned at front side, patient oral cavity and the side wing 13 that extends from two side direction patient ears, described front panel 12 is provided with pupillometry bar installing hole corresponding with the patient's eye pupil position and the wing of nose measuring stick installing hole corresponding with patient wing of nose position, described side wing 13 is provided with the corresponding ear's measuring stick installing hole in position with patient ear, described pupillometry bar installing hole, be respectively equipped with on wing of nose measuring stick installing hole and the ear's measuring stick installing hole with described jaw surface ga(u)ge body 1 removably connects and have a graduated pupillometry bar 2, wing of nose measuring stick 3 and ear's measuring stick 4.

Ear's measuring stick 4 can be respectively one, two or more, its objective is for difference according to patient's head dimensions, regulate the position of ear's measuring stick 4, make ear's measuring stick 4 corresponding with patient ear position all the time.

Described pupillometry bar installing hole, wing of nose measuring stick installing hole and ear's measuring stick installing hole are through hole, the connecting portion and the described through hole of described pupillometry bar 2, wing of nose measuring stick 3 and ear's measuring stick 4 are suitable, and described pupillometry bar 2, wing of nose measuring stick 3 and ear's measuring stick 4 are plugged in respectively on the corresponding through hole.
