With the above combination, please continue to refer to the first to the ninth figure. When the patient wants to install the full denture, it is possible to perform the static modulo using the modulating tooth structure A first. The first time to take the diagnosis, in order to facilitate the classification of the patient's size of the gums, as the basis for the production of personalized custom tooth trays.

First, in the step of "statically taking the patient's gums": the top surface of the mold 10 and the bottom surface of the lower mold 20 are respectively filled with the impression material, and then mounted on the mold material. The patient's upper and lower jaws (as shown in Figure 5) are allowed to perform static occlusion of the patient's gums by the patient's occlusion.

Since the front side of the upper mold member 10 has an upper anterior region 11, which can assist the reconstruction of the upper lip of the edentulous patient, the upper lip has a prosperous shape, and the hem portions 14 on both sides thereof have a cheek concave portion 141, respectively, which can be reliably reconstructed. The appearance of the side cheeks, and by the central position of the plate body 12, is placed against the bulging portion 15 of the upper jaw of the patient and the venting opening 151 of the bulging portion 15, which can surely attach the plate body 12 to the upper jaw of the patient.

In addition, since the front side of the lower mold member 20 has a lower anterior dentition region 21, which can assist the reconstruction of the lower lip of the edentulous patient to have a prosperous shape, and the two sides of the chin front anterior region 21 respectively have an arc shape. The cheek gums portion 22 can surely assist in reconstructing the appearance of the cheeks on both sides, and the installation comfort is high, and the top surface of the lower anterior region 21 can be aligned with the bottom surface of the upper anterior region 11 by the patient's oral engagement. As shown in the third figure, the upper and lower jaws are accurately engaged, the overall sampling speed is fast, and the appropriateness of the patient's oral cavity can be accurately judged, and the error of the denture can be eliminated, thereby reconstructing the facial cavity of the toothless patient, and the lips. The appearance of the cheeks, and the function of better chewing movement, and the function of correct pronunciation, high installation comfort and practicality.

In addition, the upper anterior region 11 and the anterior anterior region 21 have a reticle portion L, and the reticle portion L has a longitudinal reticle L1 and a plurality of horizontal reticle L2 (as shown in the fourth figure). The center line and lips of the patient's appearance can be recorded and recorded to achieve the visual beautification effect of the symmetrical appearance of the full mouth reconstruction.

In addition, in the step of "recording the bite record of the horizontal line and the vertical line of the patient": by the patient engaging the first recording device B, the patient can quickly perform the bite vertical height, the midline of the face, the horizontal line of the bite, and the level of the pupil of both eyes. Record the horizontal lines of the line and nose ear holes to provide important reference data for facial tooth reconstruction.

The main purpose is to make the articulator 50 for the patient to rub the upper jaw and the lower jaw, and then to perform the first horizontal rod according to the patient's bite vertical height, facial midline, occlusal horizontal line, two eye pupil line and nose ear hole line. 40. The horizontal height, the left and right position, and the angle of the second horizontal rod 60 and the third horizontal rod 70 are appropriately adjusted.

Since the second and third horizontal rods 60 and 70 are respectively screwed on the sliding groove 31 of the vertical rod 30, the position of the upper and lower horizontal heights can be respectively adjusted on the sliding groove 31 of the vertical rod 30, and the second and second horizontal positions can be respectively used. The three horizontal rods 60 and 70 appropriately adjust the patient's bite horizontal line, the two eye pupil line and the nose wing ear line (as shown in the seventh figure), and the overall adjustment mode is simple and convenient, and has practicality.

The first recording device B of the present invention can quickly record a plurality of facial reference lines, such as a patient's occlusal vertical height, a facial midline, a occlusal horizontal line, a two-eye pupil line, and a nasal wing ear hole line, once the patient has bitten once. The correct transfer of records to the extraoral occlusion recorder, and the subsequent data collection and complete denture production, without the need to disperse multiple parts, resulting in errors in the combination, effectively and accurately provide important reference data for facial reconstruction.

Finally, in the step of "recording the dynamic occlusion record of the patient": by the patient engaging the second recording device C, it is possible to quickly record the patient's chewing, talking facial movement, and record the metal scale. The data of the upper and lower, upper and lower, upper and lower, and lower jaw movements of the patient's mouth can be obtained to deliver accurate data of the dental model technician in making the denture.

Since the second recording device C is mounted on the first recording device B, that is, the connecting portion C21 of the upper drawing plate C2 is threaded through the adjusting groove of the upright 30, after the patient bites the upper drawing plate C2, the patient can Using the first recording device B to quickly record a variety of facial reference lines (as shown in the ninth figure), such as the vertical height of the patient after occlusion, the midline of the face, the horizontal line of the bite, the connection of the pupils of the two eyes and the line of the nose ear to provide facial teeth Important reference data for reconstruction.

Before the patient bites the upper drawing plate C2, the upper and lower gum resin must be made in the working plaster model, and the thickness is about 2 mm, so that the patient can bite, and the patient can be subjected to the bite force of the patient at the correct ideal bite height. Dynamic motion recording.

The dynamic motion recording system utilizes the patient in the oral cavity, uses the lower jaw to repeat the forward motion, and the lateral movement on the left and right sides, and finally returns to the static position, and the positional relationship is determined according to the intersection point.

The invention can accurately record the movement of the face of the patient by chewing, speaking, and applying the metal scale, and can obtain the movement data of the patient's oral cavity before, after, on the left and right, up and down, and the lower jaw, for delivery to the dental model technician. The precise data of the denture is practical.
