The operation of the present invention will be described below.

The articulator of the present invention is used in orthodontics, oral surgery,
It can be widely used for research such as prosthodontics, training, and oral diagnostic equipment.

The operation of the invention of claim 1 will be described.

First, the movement, inclination and rotation of the lower jaw model support and the upper jaw model support will be described.

A case where the lower jaw model is moved to the left, for example, 5 mm will be described.

First, after fixing the lower jaw model support base by the lower screw rod, loosen the nut of the upper screw rod, and attach the lower jaw model support base to the left side on the surface of the lower support base. See the scale line on the right side and move only 5 mm. Then, tighten the nuts on both sides to fix the upper support base. When the upper support is moved as described above, the lower jaw model fixed on the upper support can be proportionally moved to the right by 5 mm. Further, when the lower jaw model is moved backward by 5 mm, the nut of the upper screw rod is loosened, and then the front scale line attached to the surface of the lower support is moved and moved by 5 mm. Then, tighten the nuts on both sides to fix the upper support base. By moving the upper support as described above, the mandibular model fixed on the upper support is proportionally moved to the rear side by 5 mm.
You can move.

As described above, the malocclusion can be adjusted to the normal occlusion position by moving the upper and lower jaw models from side to side and front and rear. At the same time, the scale allows the deviation size to be determined, and an appropriate instruction for correction or oral surgery can be given.

Next, the lower jaw model is set to 0 °, 5 °, 10
The function of inclining at an angle of 15 ° or the like in all directions will be described.

To tilt the lower jaw model support to the left by, for example, 5 °, tighten the nuts on both the left and right sides of the upper screw rod and fix the upper and lower support. After fixing, loosen the lower screw rod and move the scale line attached to the ball body to the left only by the predetermined scale line corresponding to 5 °. As a result, the lower jaw model support is tilted by 5 °. Then, when the lower screw rod is tightened, the lower jaw model attached to the support base can be inclined by 5 ° toward the front side.

As described above, the mandibular model base is set at 0 ° and 10 °.
Even when tilting by 15 °, it is processed by the above-mentioned procedure.

As described above, when the models are attached to the respective instruments in the same manner as the ecology, the angles of the upper and lower jaw models can be adjusted, so that the models can be positioned at arbitrary positions.

When rotating the lower jaw model support base, the ball body holds the spherical surface when the lower screw rod is loosened and the upper and lower support bases are pinched to rotate in either the left or right direction. , Rotates very smoothly. After rotating by a predetermined angle, tighten the lower screw rod,

According to the present invention, the lower jaw part is mounted with the lower jaw model support base, and the same constituent members as the respective members constituting the lower jaw model support base are provided on the back surface portion of the upper jaw model frame facing each other. Since it is attached, description of its specific contents is omitted. Furthermore, since it is assembled from the same constituent members as the lower jaw model support table that is mounted on the back surface of the upper jaw model frame, its action is to move left and right, forward and backward, and to move 0 °, 5 °, 10 °, 15 °, etc. The description of the tilting in all directions and the procedure of rotation is omitted.

The operation of the invention of claim 3 will be described.

According to the present invention, the fixing spacer and the upper screw rod are fitted and the nut is screwed. That is, it is used when the upper support constituting the upper and lower jaw supporting bases is moved by a predetermined dimension to one of the left and right sides.

When loosening the nut screwed to the screw rod and moving the upper support base, for example, to the right by 5 mm,
A spacer having a thickness of 5 mm is prepared, and the concave portion having the thickness is fitted into the screw rod protruding leftward. At that time, the upper surface of the spacer is the same as the upper surface of the lower support. Therefore, the upper support does not interfere with the movement of the upper support table to the left by the upper surface of the spacer.

After the spacer of 5 mm thickness is fitted into the screw rod as described above, the nut on the left side is tightened.
Then, when the nut on the right side is tightened, the upper support base moves reliably by 5 mm. This shows a graduation line indicating 5 mm attached to the upper surface of the lower support.

As described above, it is possible to form a spacer having a predetermined thickness, for example, 1 mm, 2 mm, ... However, 1 mm
If an individual body having a thickness of 2 mm and a thickness of 2 mm is formed at the same time, the number of sheets is small and it is economical. Furthermore, when inserting the above spacer into the screw rod protruding to the right,
The procedure is the same as that described above.

Further, even in the case of the upper support with V groove which constitutes the upper jaw model support, if a spacer having a predetermined thickness is fitted into the protruding screw rod and the nut is tightened, As in the case described above, the movement proportional to the thickness of the spacer is surely made to one of the left and right sides. Therefore, the detailed description is omitted.

Further, according to the present invention, when removing the spacer which is fitted into the screw rod and tightened, the nut can be loosened,
It is very easy to remove from the screw rod immediately. When you want to move each model stand a predetermined distance again after leaving,
Select a spacer with a thickness that suits the distance, insert the spacer into the screw rod, and tighten both nuts.
As a result, the upper support can be moved by a predetermined distance.

The operation of the invention of claim 4 will be described.

According to the present invention, a washer having a recess having a predetermined thickness is removably inserted between both columns and both condyle heads. That is, by inserting a washer, the upper jaw can be raised so that it remains horizontal.

As a conventional method, the incisal guide pins are usually raised upward according to the scale of the incisal guide pins, but only the position of the upper incisal guide pin (anterior tooth portion) is raised, and the posterior (molar tooth portion) is little raised. .

However, the upper jaw can be kept horizontal by inserting and fixing a washer having a predetermined thickness between both columns and both condyle heads. Then, the front tooth portion and the molar portion can move up and down with the same size.

As described above, the washers of the present invention are provided separately with different thicknesses.
