Description

Mandibular Relations 3D Digital Recorder

The present invention relates to a mandibular duct-related three-dimensional digital recording device.

In general, the positional relationship of the mandible to the maxilla at the constant mandibular position is called the maxillo-mandibular jaw relation, which is used for the diagnosis or treatment of dental patients. In the case where the vice-versus relationship is to be acquired, the three-dimensional vice-versa- tion relationship must be accurately obtained. In the slight relationship of the mandible to the maxilla, the reference point is called the central relation, which is a horizontal vascular relationship that is acquired regularly and repeatedly under the vertical dimension of the patient. Is a non-tensionable positional relationship. There are many ways to obtain such center-centered tube relationship, but one of them is to attach the recording device to the maxilla and mandible in the oral cavity to induce the patient to exercise themselves and record the stunts through the front and rear lateral movements. Arch tracing displays a record of the limit motion of the front, rear, left and right movements on a horizontal plane.

An example of such a stunt recording may be illustrated in FIG. 1, and the front limit track 2-1 and the left, right, and lateral limit tracks 2 are centered on the vertex 2 on the recording plate 1. -2), the vertex (2), the front limit track (2-1), and the left, right, side limit track (2-2)

It is a name given that the shape is in the shape of a stunt record of a building. This vertex 2 is considered as the starting point for forward and lateral movements, and the center of ductal relationship when the recording stylus (described below) attached to the mandible is at the vertex 2 position. It is defined as (Centric relation).

At this time, in the maxillary or maxillary patients with maxillary or mandibular or maxillary or mandibular patients, the center-centered coronary relationship (the peak of the center of the maxilla) We can obtain a centric relation and form a central occlusion at that location.

However, in case of jaw patients with maxilla and mandibular jaw, maxillary relationship should be obtained at the height of tooth opening by higher than the patient's own vertical height so that the tooth does not touch. At this time, the position of the center of ductal relationship may occur on the maxillary metal plate according to the height difference with the intrinsic vertical height. In order to eliminate the difference, the iron pin contacts the recording plate perpendicularly and the tip pin (5-1) The forward inclination must be in accordance with the angle of hinge rotation along the exit track.

Looking at the structure of the mandible first, Figure 2 is a perspective view showing the structure of the mandible, Figure 3 is a side view of the mandible, the mandible (also called mandible) (3) is a horizontal axis (Horizontal axis) shown in Figure 3 (3- 1) is coupled to the upper jaw, and the lower jaw (3) is coupled to the teeth (4). The horizontal reference axis 3-1 and the central edges of the two mandibular central incisors form a bonvil triangle 3-2, which is hatched, and the horizontal plane of the tooth 4 is occlusal plane ( Occlusal Plane (3-3), the vertical plane centered on the front center of the tooth (4) is called the mid-sagittal plane (3-4). As an example as shown in FIG. 5, the iron pin 5 is provided at the intersection 3-5 of the center of the mid sagittal plane 3-4 and the two mandibular first molar 4-1.

As a result, in the case of a childish jaw patient, the tip of the iron pin 5 is positioned at the intersection point 3-5 shown in FIG. 2, and the angle of the iron pin 5 is orthogonal to the Bonville triangle 3-2 as shown in FIG. 4. The vertical plane also has a structure that tilts forward by the Balkville angle (3-6) (fixed at an angle of 17 degrees on average (an angle forward towards the vertical line of the mandibular occlusal plane 3)).

By the way, the iron pin 5 is preferably inclined by the Balkville angle (3-6), but does not move consistently around the horizontal reference axis (3-1) according to the patient point (B1, B2) of FIG. In order to coincide on the same hinge movement path, the angle of the iron pin 5 should be adjustable without being limited to 17 degrees. The iron pin 5 is installed in the lower teeth, for example, as shown in Figure 5, the iron pin 5 is installed in a screwed state to the support plate 6, the wing plate (7) on both sides of the support plate (6) It is fixed by screw 8. The iron pin (5) is screwed and the screw body is installed so that the ball pin pinch in the spring in the axial direction of the inner center, the screw threaded the upper end of the screw body and the end pin (5-1) is integrated with the nut on the top Illustrate what consists of a sieve.

Articulators were developed in U.S. Patent Nos. 4,273,533 and 4,279,595, which use a recording device in the maxilla and a record plate in the lower jaw for complete ulcer patients. In particular, there is a problem in that the use of the iron pin (stylus) is made to be used in a vertical installation configuration.

For this purpose, the practical registration No. 20-183333 developed by the present applicant to adjust the position of the iron pin constitutes the recording device 100 as shown in Figs. Create a tooth (upper and lower jaw model), attach the upper and lower jaw models randomly on the articulator (completely edentulous patients in the maxillary mandibular relationship obtained by the closed mouth impression technique. The patient is attached in a centric occulusion state, and the recording apparatus 100 is installed in the mandibular model. At the time of installation, it is possible to conveniently set the initial stage by using the reference bar made to know the horizontal and symmetrical symmetry, etc. In the case of edentulous patients, the iron pin (5) is first placed perpendicular to the mandibular occlusal plane using the reference table. Set it up close so that the iron pin is easily in position. In addition, in the dental clinic patients, the attachment pin is used to incline the iron pin 5 by about 17 degrees with respect to the mandibular occlusal plane and balance left and right. If the horizontal level using the attachment reference band in the above it can be parallel to the left and right of the recording plate with respect to the maxilla can be diagnosed in advance with the teeth to the maxilla. Therefore, the diagnosis can be conveniently applied to orthodontic or denture manufacturing or treatment of dental teeth. Also, in the case of prosthetics, placing horizontal horizontal lines, orthogonal lines, and arc-shaped bands, it is convenient to quickly set the corresponding parts.

In this case, when the tooth requires a prosthesis or denture, the articulator makes a recording device 100 as shown in FIG. In fact, as described above, the support pins 70 are adjusted in advance according to the shape of the patient to install the substrate 60 at a desired position, and the recording device 100 is held at the initial position such as the center as the attachment reference in the mandible model. Then fix the iron pin (5) at an angle using a fastening screw (54). In this case, the complete edentulous patient is fixed perpendicular to the mandibular occlusal plane, and the dental detained patient is inclined forward 17 degrees with respect to the mandibular occlusal plane. In this state, the cap 11 of the transfer plate function is put on the top of the iron pin 5 as shown in FIG. 7, and the conjugate 1-1 on the gel is placed on the maxillary corresponding site (the maxillary palatal surface 30) of the articulator. After applying, closing the maxillary portion of the articulator, the recording plate 1 is moved from the cap 11 to the assembly 1-1 and fixed, which is a combination of the temporary fixing of the recording plate 1 after a certain time. In the state where 1) is hardened, the recorder is adjusted to fit the maxilla and integrated into a gel-like assembly. Then, refit the cap 11 to the tip pin 5-1 so that the iron pin 5 is perpendicular to the changed upper maxillary recording plate, and loosen the captive screw 54 so that the cap 11 and the recording plate 1 are After making contact, tighten the tightening screw (54).

In this state, the assembly 1-1 having the recording plate 1 and the recording apparatus 100 shown in Fig. 6 are separated from the articulator. And it is coupled to the patient's teeth as shown in Figs. 6 and 7 (since the tooth shape is the same as the patient's own teeth and the tooth model attached to the patterned articulator, in Fig. Teeth are shown identically). If there is a slight error, you can adjust it regularly by adjusting screws. In the oral cavity of a dental clinic patient, the height of the iron pin is changed by 3-4mm so that the two vertices coincide with each other by performing a gothic arch tracing.

However, this method also has the advantage of adjusting the angle of the iron pin, but because the three-dimensional structure of the mandibular condyle and the jaw joints that function as the upper and lower jaw of the human body is different from person to person, even in the articulator using the same recording board It is difficult to make a personalized recording for each person because it can be adjusted only at a certain angle.

8 is a perspective view of another example of the recording apparatus, in which a support pin 70 is fixed to the surface of the tooth through a screw 71 at the edge of the substrate 60 and a support plate 51 is mounted on the substrate 60. The substrate 60 and the support plate 51 support the ball 40 to each other, and the ball 40 couples the iron pin 5 whose height is adjusted. In order to adjust the position of the support pin 70, the long hole 72 is placed on the substrate 60 so as to be adjusted. In the recording device of the above structure, the original design also installs the mandible movement path reproducing rod 90 supporting the length of the screw 60 in a vertically screwed state based on the substrate 60 and the support plate 51. The reproducing rod 90 is installed at three circumferential positions of the ball 40 supporting the iron pin 5.

9 is a block diagram of the articulator, which supports the lower jaw 81 and the upper jaw 82 in the form of a tooth with a vertical bar 83, a handle 86 at the tip of the upper jaw 82, and hinges at both sides. By installing the rod 84, the hinge rod 84 is configured to be supported by the hinge groove 87 formed on the upper end of the vertical bar (83). The hinge groove 87 is coupled to the hinge rod 84 at the upper end of the vertical bar 83 to install the jaw portion 85 which reproduces the condyle of the mandibular condyle and the mandibular condyle in the jaw joint movement. . The jaw joint portion 85 is hardened to use after recording the shape of the condyles using a resin or the like to implement the combination (1-1). In this case, Figure 9 is a cross-sectional view showing a form in which the cap 92 of the screw rod 91 forming a reproducing rod 90 to the combination (1-1) initially coupled to the upper jaw opening 30 and FIG. In the enlarged cross-sectional view of the main portion, the curved head 93 is integrally formed at the distal end of the cap 92 covered by the screw rod 91 of the reproducing rod 90 on the assembly 1-1 supporting the recording plate 1. Achieve the configuration shown. The cap 92 is configured to press the assembly 1-1 through the recessed container 94.

However, this method uses a articulator to fix the recording plate of the mandibular ocular relationship in the union, and records the Gothic arch from the mandible and the maxilla of the human body to record the accurate ductal relationship and to correct and correct the mandibular position. It is limited to performing classical functions that are intended to be used in.

The present invention has been made to solve this problem, and an object of the present invention is to recognize three-dimensional relations of vice-versa on the vice-recording recorder and the recording board, and to store the recognition values as digital values, thereby enabling detailed three-dimensional state detection, teaching and reproduction. It is to provide a three-dimensional digital recording device of the villain relationship.

The present invention facilitates leveling during recording by using a horizontal reference indicator having a horizontal reference axis indicator so that the duct relations can be performed around the horizontal reference axis, and at the center of the horizontal bar and the distance between the horizontal reference axis indicator and the leg portion. Based on the distance between the occlusal plane, which is the center of the tooth, and the bonebil triangle, the mandibular relationship can be represented by the virtual articulator using the 3D CAD cam, and the abnormality of the vascular relationship can be determined and the deviation from the normal position can be plotted. It is to provide a three-dimensional digital recording apparatus for the vice-relative relationship.

To this end, the present invention is a recording device installed on the occlusal plane of the mandible to support the iron pin with a support plate and to record on the recording plate, and

It is a mandibular pit-related tube recording device having a recording means for recording the mandibular umbilical relations with iron pins in the form of Gothic arches.
