DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings.

2, the Gothic arch tracer according to an embodiment of the present invention comprises an edentulous upper and lower incisor (a, b) and an edentulous and mandibular lower mandible (c, d) 100 ', 200, 200' and the trays 100, 100 ', 200, 200' have fixing protrusions to fix the Fox plane and fix the upper and lower mandibles.

Here, the premolar portion side of the edentulous maxillary tray 100, which is a portion A and a portion B, can be cut out to make a child-friendly maxillary tray 100 '. The same goes for the mandrel trays 200 and 200 '.

This is because the mandibular movement is minimized by minimizing the distance between the upper and lower mandibular trays 100 'and 200' in the first and second mandibular movements, thereby preventing early contact due to the trays 100 'and 200' have.

2, each of the trays 100, 100 ', 200, and 200' includes an interpupillary line - a pair of indicator protrusions 104 and 104 'that guide parallel lines to the pupil line, The engaging projections 102 and 102 'for engaging the occlusal plane guide projections 106 and 106' for guiding the occlusal plane on the side face and the Fox plane 300 are constituted.

That is, according to an embodiment of the present invention, the tray 100 is provided with an occlusal plane indicator protrusion which is indicated by two points in front and two points in front and back on both sides.

As shown in FIG. 5, the Fox plane 300 is inserted into the fitting portion 402 of the op meter 400, and parallel to the interpupillary line on the front side and parallel to the Camper's plane on the side, Allows you to find the plane.

In addition, the distance between the upper and lower mandibular traces 100 'and 200' should be minimized to keep the maxillary incisors in contact with each other as much as possible.

On the other hand, referring to FIG. 7, the edentulous maxillary tray 100 is manufactured based on a commercially available upper and lower maxillary tray, and the staging plate can be slidably formed so as to cover 15 mm from the anterior portion to the rear portion. On the other hand, the edentulous mandible tray staging plate 206 covers the entire mandibular tray.

As shown in FIG. 8, the upper plate and the lower plate are made of magnetic metal, and the lower plate is coupled with an upper portion where a picture is well drawn and a lower portion where a magnet is attached well. That is, the upper and lower tray 100 and 200 are mounted in the oral cavity via the magnet 800 to the edentulous Gothic arch tray 100 and the staging boards 109 and 206, respectively.

For example, it is preferable that the upper portion is a plastic plate and the lower portion is a metal plate having a good magnetism. The dimple is formed on the apex Apex when the goddock arch is drawn by the stab 610 on the mandible plate 206 of Fig. 7, so that the Gothic arch is drawn well.

Here, since the edentulous state has enough vertical space, the thickness of the magnet 800 having a certain thickness should be varied.

As shown in FIG. 9, it is possible to find the occlusal plane in parallel with the interpupillary line on the front side and in parallel with the Camper's plane on the side, and the upper plate is made thick so as to fix the middle needle on the inner side, The thread needle is fixed at one end thereof to a screw head shape having a diameter of 6 mm so as to be able to adjust its length by turning it with a ratchet, and a groove is formed in the middle of the needle needle , Which will be described in detail below.

As shown in FIG. 2, the fixing protrusions are four protrusions 108-1 and 108-2 formed outside the tray 100, which are protrusions for fixing the upper plate, 300 are formed at the front and rear sides of the fixing projections 102.

As shown in FIGS. 3 and 5, the fixing hole 302 is formed in front and rear in the Fox plane 300.

As shown in FIG. 7, the upper plate is fixed to the fixing protrusions 108-1 and 108-2, and the stool is formed on the upper plate. As shown in FIG. 11, the lower tray is aligned with the upper tray, + &Quot; shape on the surface of the magnet, a " + " shape is displayed on the surface of the magnet, and one side of the magnet is positioned on the projection Is formed and is inserted into the hole of the upper artillery. At this time, the needles are separated from the maxillary plate.

As shown in Fig. 11, a mandrel tray 200 according to another embodiment of the present invention is depicted with a " + 250 " in the mandibular plate on which the gothic arch is drawn by the stitch needle. The magnet is fixed to the lower tray 200 with the wax in accordance with the heat and the magnetism. As a result, the upper and lower tray 100 and 200 are positioned in the center of the face.

The reason is that the maxillary tray is positioned in the center of the skull by the Fox plane 300 and the operator 400 and the mandrel tray 200 is positioned in the center of the maxillary tray 100 by the magnets.

When the mandibular tray 200 does not exactly match the mandible in the mouth when the mandibular tray 200 is tilted (i.e., the upper and lower balance is broken), the mandible of the patient may be left and right Because they are twisted in a direction.

In this case, when the mandibular tray 200 is placed in the mandible, the mandibular tray may not fit into the mandibular arch precisely unless it is separated from the maxilla.

In this case, the upper and lower tray 100 and 200 are parallel to each other with the magnets parallel to each other, and the upper and lower midline lines do not coincide with each other.

The mandibular tray 200 is placed in the oral cavity, so that the midline of the mandible is different from the maxilla.

Then, the rubber impression agent is filled in the lower tray 200, the position of the lower tray 200 is adjusted by moving the lower tray 200 to the left and right, and the upper and lower jaws are closed to wait for the hardening. Record the relationship between the mandibular condyles in this state.

In addition, it is desirable to adjust the length with a wrench so that the distance from the nose tip to the chin becomes a certain length (male mean 70-75mm, female 65-70mm) after joining the upper needle.

 In addition, the maxillary and mandibular plates are preferably made of metal that is magnetic and has good adhesion.

 In addition, the upper plate is made thick so as to fix the needle in the middle of the inner side, and a female thread is made there to fix the needle.

7 can be freely adjusted in length by, for example, placing a hexagon head 620 having a diameter of 6 mm on the end portion thereof and turning it with a ratchet.

Namely, the upper needle plate 610 and the hexagonal head plate 620 are integrally formed and can be turned by ratchet to adjust the length.

In addition, the striking needle 610 has a sharpened tip, and a shape similar to that of the ballpoint pen tip can be stuck thereto.

As shown in FIGS. 4 to 6 and 9, the Gothic arch tracer according to the present invention described above is characterized in that the fox plane is fixed to the upper tray 100, the rubber impression material is filled therein, Fix to the maxilla parallel to the camper's plane (A, B, C), wait for cure, remove the fox plane after curing.

Subsequently, the upper tray 100 is inserted into the hole of the upper plate, the middle magnet is inserted, and the lower tray 200 is fixed with the lower tray 30 attached thereto.

In this case, the camper's plane, the maxilla and the mandible are all made in parallel. It is possible to test the position of the mandibular tray in the oral cavity by virtually moving the mandrel tray 200 in the front, back, left, and right directions according to the mandibular arch.

In another embodiment of the present invention, as shown in FIG. 6 (a), parallel to the interpupillary line and parallel to the camper's plane at the side of (b), the fox plane is fixed to the upper tray 100, And then fixed on the upper side parallel to the interpupillary line on the side and parallel to the camper's plane on the side, and then waited for curing. After curing, removal of the fox plane finally results in parallel to the occlusal plane.

Then, the upper tray is inserted into the upper tray 100, the middle magnet is inserted, and the tray with the lower tray is fixed. In this case, the camper's plane, the maxilla and the mandible are all made in parallel. At this time, adjust the height with a magnet so that the distance from the nose tip to the chin is a certain distance (male average 70-75mm, female 65-70mm).

Then, the rubber impression agent is filled in the lower tray and the upper and lower jaws are closed to wait for curing.

Then, adjust the length with a wrench so that the distance from the nose tip to the chin is constant after joining the needle of the upper plate.

In summary, the present invention relates to a method and apparatus for recording a mandible, the method comprising the steps of: recording a mandibular central incisor relationship using a Gothic arch tracer in an edentulous patient; scanning a CR bite through a scan module; A step of setting a maxillary / mandibular occlusion, and a step of fabricating a base by selecting one artificial tooth arrangement model through a library module.

For example, in the step of selecting a single artificial tooth arrangement model through a library module and fabricating a base, each of the 2880 teeth can be input.

Depending on the shape of the anterior teeth, there are 3 variables, 3 variables depending on the anterior color, 8 variables depending on the posterior shape, 3 according to the width on the mandibular plane, and 10 on the occlusal plane angle.

For example, 3 * 4 * 8 * 3 * 10 = 2880 combinations can be selected at will, and depending on the parameters such as facial asymmetry, the dentist can attach the resin teeth.

Subsequently, three virtual planes are formed as shown in FIG.

1. Maximal model base plane (a) ?? Gothic Arch Tracer Extrude the plane at the appropriate distance from the plane connecting the three corners.

2. Occlusal plane (B) - Vertical position is the point of central incisor on the Gothic arch tracer and plane parallel to the maxillary model base plane

3. Mandible model base plane (c) ?? Gothic Arch Tracer Extrude the plane at the appropriate distance from the plane connecting the three corners.

18, the occlusal plane angle is given by the smart facebow. Smart facebow refers to the measurement of the occlusal plane angle by a computer program by inserting the rubber band on the flat surface and taking a picture.

If it is assumed to be 15 degrees, the occlusal plane angle should be such that it looks like it is mounted on the articulator.

Here, the Gothic arch tracer assumes coordinates (X = 0, Y = 0, Z = 0) The occlusal plane angle is given by the smart facebow. Assuming 15 degrees, if the occlusal plane angle is given, the posterior space coordinates are determined.

The tooth template is placed in the maxillary occlusal plane. The anterior portion is aligned with the CR bite anterior portion and the posterior portion is positioned parallel to the occlusal plane.

As shown in FIG. 19, the method of arranging the teeth in the virtual space assumes coordinates (X = 0, Y = 0, Z = 0) between the center teeth on the Gothic arch tracer.

As shown in FIG. 20, three maximal occlusal planes are given to the maxillary teeth to be scanned (between the maxillary central incisors and the 6th mesial lingual cusp).

As shown in FIG. 21, a register file is created by transferring the scanned tooth data to the Gothic arch tray file using the registeration point between the both central teeth and the side projections on both projections on the front side. The Gothic arch tracer remembers only the coordinates and erases the rest of the data.

As shown in FIG. 21, when the template teeth are placed on the coordinates of three points, the teeth are positioned on the upper and lower spaces.

Finally, to make the base with CAD, we store the standard total denture outline data that we have pre-made in the library, enlarge and reduce the data, and create the outline data of the total denture with mucosal surface, polished surface and artificial tooth .
