In the case of partial dentures, there is a residual tooth. Therefore, the denture can be made on the portion without a tooth based on this. However, since the complete denture has no standard tooth, the position of the occlusal plane relative to the facial, Relationship, and soft tissue appearance in the oral cavity.

Specifically, when a patient visits, the dentist examines and diagnoses whether the patient's denture or gingiva is suitable for supporting the denture, whether there is an intraoral structure that interferes with denture making, and the like. If there is no abnormality, preliminary impression is made using the ready tray. We construct a research model using preliminary impression, and design a personalized tray to accurately express the patient 's oral condition using the research model. Next, a function tray (or a precise tray tray) is used to obtain a function increase (or a precise increase). Using the functional impression, the main model is made and the upper and lower jaw relations are made by making the recording image and the occlusion agent on the main model. Arrangement of artificial teeth in the occlusion agent is performed to demonstrate the value of lead, and finally the total denture is completed.

This manufacturing process depends on the experience and skill of the dentist and it is very difficult to predict the outcome of the treatment. In addition, in order to produce a complete denture suitable for a patient, it is necessary to reflect the whole patient information of the patient's face, head and neck, upper and lower mandible.

The imaging device may be configured with, for example, Cone Beam Computerized Tomography (CT). The cone beam CT detects the cone-shaped transmission X-ray two-dimensionally using an area detector and obtains the three-dimensional volume information by using it to generate a 3D image by only one rotation scan of the object. Cone beam CT is a device that accurately generates hard tissue images of the head, such as the maxilla, mandible, ridge, alveolar bone, and root. However, it can also generate soft tissue images of the contour of the patient's face. Further, when the patient is taking a cone beam CT in a state where the separation member is held between the upper and lower mandibles, the soft tissues can be accurately represented because the upper and lower soft tissues are separated from each other by the spacing member and the impression material contained therein.

Because the 3D image contains all of the patient's anatomical information to create a complete denture, the dentist can produce accurate, wear-friendly dentures based on this. The dentist connects to the design device through the user terminal and sets a reference line on the soft tissue image, hard tissue image, or a combined image thereof displayed on the screen. Here, the reference line is a reference line for the design of a complete denture, and includes a line on the face and head and neck, a camper's plane, a Frankfort horizontal plane, a pupil trunk, (Upper eyelid), upper eyelid (upper eyelid), upper eyelid, lower eyelid, or a combination thereof. The dentist can determine the position of the recording, occlusal or artificial teeth by checking the soft tissue images and hard tissue images based on these reference lines. The designing device can display simulation of the change of the face or facial according to the position change of the artificial tooth. Upon completion of the recording, the design of the occlusal agent or the artificial tooth, the designing device stores the image of the structure (recording image, occlusion agent, or artificial tooth) in a STL (STeroLithography) file format.

The spacing member 10 includes a top deformation tray 12, a mandible tray 14, and a connecting member 16 for adjusting the distance between these trays. The upper deformation tray 12 and the lower tray 14 each have a tray shape for pulling up and have an impression material for forming a pattern on the inside. Thus, the patient is gripping the spacing member 10 in the oral cavity. This impression material and spacing member 10 serve to more clearly reveal the intraoral soft tissue of the patient in subsequent tomography. The connecting member 16 is configured to adjust the distance between two trays by connecting the upper and lower tails 12 and 14 to each other. For example, the connecting member 16 may be provided with threads on the outer circumference thereof to adjust the tray interval by rotating movement. It is very important to determine the horizontal or vertical relationship between occlusal height or vertical height and malocclusion in an edentulous patient. In the present invention, before designing the complete shape of the complete denture, Is determined.

A person's dentition is caused by many causes such as malocclusion, growth pattern, loss of teeth, movement of teeth due to tooth loss, congenital defect, remnant of toothpick, malpractice such as dry mouth, jaw face anomaly, jaw face defect, Have various arrangements. In the restoration or orthodontic treatment of teeth, a treatment plan is established considering these causes. If the tooth is partially defective, the treatment plan such as the length of teeth or occlusion can be made with reference to the remaining dental condition. However, in an edentulous patient with no teeth, the complete denture must be designed by relying on reference points or reference lines based on the soft tissue, skull, and mandible of the face.

The occlusal plane and midline are important factors in the complete denture design of edentulous patients, on which records, occlusal or artificial teeth are arranged. The occlusal plane refers to the horizontal virtual plane formed by the occlusal surface of the teeth as the entire dentition, preferably the occlusal plane is set substantially parallel to the pupil trunk line or camper plane. Especially, in edentulous patients, it is difficult to set the occlusal plane directly because there is no tooth at all, and it is inevitable to set it with the help of reference lines (pupil trunk line, camper plane, etc.). In addition, the midline is the line representing the center of the tooth, and is set to match the center of the head and neck because there is no standard tooth for the edentulous patient.

Since the 3D image of the present invention is photographed while the patient is holding the spacer member 10, the occlusion diameter has already been determined. Therefore, recording, occlusal, or artificial teeth can be designed while referring to the patient's soft and hard tissues based on the occlusal plane and the midline shown in the 3D image. 6, the position of the artificial tooth can be determined based on the occlusal plane, the midline, the reference line, etc. while referring to the soft tissue image and the hard tissue image of the patient's head, i.e., anatomical information. When the patient is taking a cone beam CT while the patient is holding the separation member 10, the dentist can determine the ratio of the face, the esthetics of the facial feature, the relation between the upper and lower mandible, the relation between the tongue and the ball in the mouth, The three-dimensional position of the artificial tooth can be arranged while checking the horizontal relation of the preparation. Therefore, clinical errors such as errors in the occlusal plane can be significantly reduced. In addition, since such 3D images and design data are transmitted to the technician, the possibility of failure of treatment due to communication difficulties between the dentist and the technician can be significantly reduced. Further, when the position of a structure (recording image, occlusion agent, or artificial tooth) is changed in the oral cavity on the 3D image, the result of the treatment can be easily predicted when the change of the patient's face is displayed on the screen by simulation. The images of these structures are stored as design files in the STL file format.

At the first visit, the edentulous patient records the cone beam CT at the door, and the dentist uses the anatomical reference line from the photographed 3D image to output the recording, occlusal or artificial values. During the second visit, if the patient shows occlusal or dentures and the lungs are removed, the dentist will arrange the teeth to complete the dentures. At the third visit, the patient is finally fitted with a denture. Thus, the patient's convenience can be maximized by reducing the number of visits to the patient. In addition, it can contribute to increase productivity by lowering doctor's time and frequency of treatment. In some cases, it may be possible to omit the poetic and discontinuity phases.
