The first is to first determine the hinge axis of the patient's mandibular movement and transfer the relationship between the upper and lower jaw dentition models and the hinge axis to the On the shelf, The vertical distance of the frame elevation is used to determine the jaw position required for treatment. However, due to the lack of a method for accurately locating the dynamic hinge axis, There is a certain error between the jaw position relationship obtained by the vertical distance of the frame raising and the patient's actual jaw position relationship, which will affect the accuracy of the restoration occlusal contact. The second method is to directly determine the actual jaw position relationship after the vertical distance required for treatment in the patient's mouth. However, due to the limited field of view, it is difficult to observe the restoration space in the posterior tooth area during intraoral operation, and it is not easy to judge whether the vertical distance raised meets the treatment needs.

[0053] In order to clearly understand the preparation method of the dental occlusal recording device provided in the embodiment of the present application, the distribution of teeth in the oral cavity is introduced by taking the upper jaw as an example. Figure 1 FIG. 1 is a diagram of the maxillary dentition structure according to an embodiment of the present application. Figure 1 In the structure shown, the tooth labeled 1 is the central incisor, the tooth labeled 2 is the lateral incisor, the tooth labeled 3 is the canine, the tooth labeled 4 is the first premolar, the tooth labeled 5 is the second premolar, the tooth labeled 6 is the first molar, the tooth labeled 7 is the second molar, and the tooth labeled 8 is the third molar.

[0054] Specifically, the maxillary dentition is bilaterally symmetrical, and the number and structure of teeth on each side are teeth numbered 1 to 8. It is worth noting that the central incisor numbered 1 and the lateral incisor numbered 2 can be collectively referred to as incisors; the six teeth numbered 1 to 3 can all be called anterior teeth and form the anterior tooth area, and the rest are posterior teeth and form the posterior tooth area. Of course, the mandible has a tooth classification corresponding to the maxilla, which will not be repeated here.

[0055] Among all the teeth in the upper and lower jaws, the teeth in the anterior area are composed of four faces and the incisal edge, and the teeth in the posterior area are composed of five faces. The details are as follows:

[0056] 1. Labial surface and buccal surface: The side of the front teeth close to the lips is called the labial surface, and the side of the back teeth close to the buccal mucosa is called the buccal surface.

[0057] 2. Lingual surface and palatal surface: The side of the tooth close to the tongue is called the lingual surface. The lingual surface of the maxillary teeth is close to the upper palate, also known as the palatal surface.

[0058] 3. Occlusal surface and incisal edge: The surface of the back teeth facing each other and chewing food on it is called the occlusal surface. The incisal edge of the front teeth facing each other and biting things, like the blade of a kitchen knife, is called the incisal edge.

[0061] Step S202: Match the patient's upper and lower dentition data to the virtual shelf;

[0062] Step S203: In the virtual Adjust the height of the cutting guide pin on the articulator to determine the vertical distance required for treatment and complete the virtual articulator setting;

[0063] Step S204: forming a dental occlusal recording device in the virtual maxillary dentition according to the vertical distance required for treatment, the dental occlusal recording device comprising an anterior teeth guide portion, an occlusal platform and a posterior teeth recording portion;

[0064] Step S205: obtaining preparation parameters of a dental occlusal recording device;

[0065] Step S206: preparing a physical body of the dental occlusal recording device according to the obtained preparation parameters of the dental occlusal recording device.

[0066] The method for manufacturing a dental occlusal recording device provided in the embodiment of the present application determines the vertical distance required for treatment based on the virtual dentition by digital technology, designs a virtual dental occlusal recording device based on the vertical distance, and manufactures a physical dental occlusal recording device according to the manufacturing parameters of the virtual dental occlusal recording device. It should be understood that the design and manufacture of a dental occlusal recording device using digital technology is simple and convenient, with high precision, and is convenient for clinical trial fitting and determination of jaw position relationship.

[0067] It is worth noting that the dental occlusal recording device prepared by the manufacturing method of the dental occlusal recording device provided in the embodiment of the present application can retain the predetermined vertical jaw position relationship information required for treatment through the occlusal platform, and the intraoral operation only needs to determine the horizontal jaw position relationship, which can reduce the difficulty of intraoral operation. At the same time, the dental occlusal recording device obtained by the manufacturing method provided in the present application can directly record the real jaw position relationship required for restoration in the mouth, which can avoid the need for physical The error introduced by operating the hinge axis on the frame can improve the accuracy of determining the jaw position relationship.

[0068] In one embodiment of the present application, please refer to Figure 3 The method of obtaining the upper and lower dentition data of the patient when the cusps are staggered in step S201 exemplarily includes:

[0069] Step S301: Obtaining upper and lower teeth table data;

[0070] Step S302: Acquire buccal surface data of posterior teeth on both sides of the upper and lower dentition when the cusps are in interdigitated position;

[0071] Step S303: After alignment, a virtual upper and lower dentition is obtained with a cusp staggered relationship.

[0072] It should be noted that the upper and lower dentition data of the patient when the cusps are in an interdigitated position obtained in the method for manufacturing the dental occlusal recording device provided in the embodiment of the present application is the basis for forming a virtual dental occlusal recording device.

[0073] Exemplarily, the data in the above steps S301, S302 and S303 may be acquired through a dental scanner.

[0074] It should be noted that before performing step S202, the patient's upper and lower dentition data obtained in step S201 can be imported into the restoration design software. The restoration design software can be exemplarily DentalCAD ​​restoration design software of German exocad company. Of course, other restoration software can also be selected according to needs, which will not be repeated here.

[0075] In the repair software, step S202 exemplarily includes:

[0076] Align the mesial adjacent points of the maxillary central incisor and the mesial buccal cusp points of the first molars on both sides in the patient's dental data to the virtual The average of the preset plane to complete the virtual Rack settings.

[0077] It is worth noting that in step S203, the virtual The vertical distance of the cutting guide pin is raised to observe the occlusal separation of the anterior and posterior teeth of the virtual upper and lower dentition. The vertical distance required for treatment is determined according to the appropriate separation space to complete the virtual Rack settings.

[0078] In one embodiment of the present application, please refer to Figure 4 The method of forming a dental occlusal recording device in the virtual maxillary dentition in step S204 includes:

[0079] Step S401: forming a front teeth guide part and a back teeth recording part matrix in the virtual maxillary dentition;

[0080] Step S402: adjusting the posterior teeth recording part base to form the posterior teeth recording part;

[0081] Step S403: forming an occlusal platform on the lingual surface of the anterior teeth area of ​​the virtual maxillary dentition.

[0082] In step S401, the method of forming the anterior teeth guide part and the posterior teeth recording part base may include:

[0083] Determine the positioning direction of the dental occlusal recording device in the virtual maxillary dentition, perform virtual undercut filling, and obtain surface data after undercut filling;

[0084] Set the edge line of the dental bite registration device on the virtual maxillary dentition so that the edge line covers the maxillary posterior teeth area Surface, as well as, covers the lingual surface, incisal tip and part of the labial surface of the upper anterior teeth;

[0085] The surface data falling within the margin line range is thickened to obtain the anterior tooth guide covering the incisor lingual surface and incisor tip and the canine lingual surface and canine tip. At the same time, the posterior tooth area is covered. Of course, the posterior teeth recording part can also cover the lingual surface of the maxillary posterior teeth, which can be specifically set according to needs and will not be repeated here.

[0086] It is worth noting that the degree of surface data thickening can refer to the occlusal separation distance of the anterior teeth area, and ensure that the inclination of the anterior tooth guide is consistent with the original anterior tooth lingual surface, so as to retain the original anterior tooth guide information and provide a reference for the restoration design. Of course, it can also be adjusted based on the original anterior tooth guide according to treatment needs. Exemplarily, the degree of surface data thickening is equal to the occlusal separation distance of the anterior teeth area.

[0087] The method of forming the posterior teeth recording part in step S402 may include:

[0088] According to the virtual The occlusal separation distance of the upper and lower jaw teeth on the frame is adjusted, and the thickness of the posterior tooth recording part base is adjusted to obtain the posterior tooth recording part that is occlusally separated from the virtual mandibular posterior teeth.

[0089] It is worth noting that the posterior teeth recording part formed by the posterior teeth recording part base needs to ensure that it is separated from the lower posterior teeth occlusal occlusion. Exemplarily, the separation distance is 0.2mm-2mm to provide space for accommodating the occlusal recording material.

[0090] The method of forming the occlusal platform in step S403 may include:

[0091] In the virtual maxillary anterior teeth lingual surface generation and The plane-parallel occlusal platform enables the lower surface of the occlusal platform to be in occlusal contact with the virtual mandibular anterior teeth, and the occlusal surface extends toward the lingual side along the anterior-posterior horizontal direction and exceeds the incisal end of the virtual mandibular anterior teeth.

[0092] It should be noted that the contact width between the lower surface of the occlusal platform and the virtual mandibular anterior teeth in the left-right direction is approximately two lower anterior teeth widths, and extends at least 2 mm beyond the incisal tip of the virtual mandibular anterior teeth in the anterior-posterior horizontal direction and the occlusal surface toward the lingual side to ensure the effectiveness of the anterior-posterior occlusal contact range.

[0093] It is worth noting that after completing step S205, the obtained preparation parameters of the dental occlusal recording device can be saved in STL format to facilitate subsequent physical manufacturing of the device.

[0094] In one embodiment of the present application, in step S206, the method for preparing a physical body of the dental occlusal recording device according to the obtained preparation parameters of the dental occlusal recording device includes:

[0095] According to the obtained preparation parameters of the dental occlusal recording device, a dental occlusal recording device made of resin material is manufactured by 3D printing or cutting.

[0096] Figure 5 and Figure 6 A dental occlusal recording device is provided for the embodiment of the present application. Please refer to Figure 5 and Figure 6 The structure shown is that the dental bite recording device is used for the upper jaw, and the dental bite recording device includes an anterior teeth guide part 10, an occlusal platform 20 for providing a vertical stop point and assisting in determining the jaw position relationship, and a posterior teeth recording part 30 for recording the jaw position relationship.

[0097] In a possible implementation, the anterior teeth guide portion 10 covers the lingual surface of the incisor and the incisal tip of the incisor, and covers the lingual surface of the canine and the cusp of the canine;

[0098] The occlusal platform 20 is provided on the anterior teeth guide portion 10 and is located on the anterior teeth lingual surface. The lower surface of the occlusal platform 20 is The planes are parallel, and the lower surface of the occlusal platform 20 is used to produce occlusal contact with the mandibular anterior teeth in the occlusal state, and the occlusal platform 20 provides a vertical stop point for occlusal contact with the lower anterior teeth to retain the predetermined vertical distance information;

[0099] The posterior teeth recording part 30 covers the posterior teeth area The posterior teeth recording portion 30 has a bearing surface for bearing the occlusal recording material, and the bearing surface of the posterior teeth recording portion 30 is separated from the occlusal contact of the mandibular posterior teeth to provide a space for accommodating the occlusal recording material.

[0100] It should be noted that the front teeth guide part 10, the occlusal platform 20 and the posterior teeth recording part 30 in the dental occlusal recording device provided in the embodiment of the present application are all arranged in the upper jaw, wherein the occlusal platform 20 is located on the lingual surface of the front teeth, which can provide a vertical stop point for occlusion, retain the pre-determined vertical distance information, and can also assist in determining the horizontal jaw position relationship. It should be noted that the dental occlusal recording device provided in the embodiment of the present application retains the pre-determined vertical jaw position relationship information, so that only the horizontal jaw position relationship needs to be determined in the mouth, thereby simplifying the intraoral operation. At the same time, when the dental occlusal recording device provided in the embodiment of the present application is used, after the jaw position relationship required for treatment is determined by the occlusal platform 20, the occlusal recording material can be injected into the posterior teeth recording part 30 to record the jaw position relationship. The dental occlusal recording device can improve the accuracy and stability of determining and recording the jaw position relationship, thereby improving the treatment effect on the patient.

[0101] It should be understood that the lower surface of the occlusal platform 20 actually refers to the side surface facing the mandibular bone. The plane is an imaginary plane formed by the mesio-adjacent point of the maxillary central incisor to the mesiobuccal cusps of the bilateral first molars. The plane is parallel to the nasal wing-tragus line and basically divides the intermaxillary distance in half.

[0102] It is worth noting that the dental occlusal recording device provided in the embodiment of the present application can be prepared using the manufacturing method of the dental occlusal recording device provided in the embodiment of the present application.

[0103] In one embodiment of the present application, please continue to refer to Figure 5 and Figure 6 The structure shown can set the inclination of the anterior teeth guide part 10 to be consistent with the inclination of the anterior teeth lingual surface before treatment. It should be noted that when the inclination of the anterior teeth guide part 10 is consistent with the inclination of the anterior teeth lingual surface before treatment, the original anterior teeth guide information can be retained to provide a reference for the restoration design. Of course, it can also be adjusted based on the original anterior teeth guide according to the treatment needs.

[0104] Please continue to refer to Figure 5 and Figure 6 In the structure shown, in one embodiment of the present application, the thickness of the anterior teeth guide portion 10 is equal to the distance of the occlusal separation of the anterior teeth area.

[0105] In one embodiment of the present application, along the left-right direction, the lower surface width of the occlusal platform 20 is the width of two mandibular anterior teeth. Of course, the lower surface width of the occlusal platform 20 is not limited to the width of two mandibular anterior teeth, and can be larger or smaller than this width as required.

[0106] When setting the structure of the occlusal platform 20, in one embodiment, along the front-back horizontal direction, the lower surface of the occlusal platform 20 extends toward the lingual side and exceeds the incisal end of the lower front teeth by at least 2 mm to ensure the effectiveness of the front-back occlusal contact range. It should be understood that left and right refer to the left and right sides of the cheek, the side where the human face is located is the front, and the side of the back of the head is the back.

[0107] Please continue to refer to Figure 5 and Figure 6 In the structure shown, the separation distance between the posterior teeth recording part 30 and the mandibular teeth is used to place the bite recording material. Specifically, a space for accommodating the bite recording material is provided on the bearing surface of the posterior teeth recording part 30. In other words, since the posterior teeth recording part 30 is occlusally separated from the mandibular teeth, there is a certain interval between the bearing surface and the mandibular teeth, and the interval space is the accommodating space. It should be noted that after the jaw position relationship required for treatment is determined by the occlusal platform 20, the bite recording material is injected into the posterior teeth recording part 30 to record the jaw position relationship, which can improve the treatment effect on the patient.

[0108] When setting the structure of the posterior teeth recording part 30, in one embodiment, the occlusal separation distance between the bearing surface of the posterior teeth recording part 30 and the mandibular posterior teeth is 0.2 mm to 2 mm.

[0109] Of course, the posterior teeth recording part 30 can also cover the lingual surface of the maxillary posterior teeth. The specific configuration can be based on the actual needs and will not be elaborated here.

[0110] The present application also provides a Figure 5 and Figure 6 The method of using the dental bite recording device shown in the figure is as follows: Figure 7 As shown, including:

[0111] Step S701: Install the Figure 5 and Figure 6 The dental bite registration device shown;

[0112] Step S702: Determine the jaw position relationship through the anterior tooth guide 10 and the occlusal platform 20;

[0113] Step S703: Record the patient's jaw position through the posterior teeth recording unit 30.

[0114] Specifically, in the method for using the bite record device provided in the embodiment of the present application, after the jaw position relationship required for treatment is determined through the bite platform 20, the bite record material is injected into the posterior tooth record part 30 to record the jaw position relationship, which can improve the stability of the bite record, thereby improving the treatment effect on the patient. At the same time, since the dental bite record device provided in the embodiment of the present application retains the vertical jaw position relationship information determined in advance through the bite platform 20, it only needs to determine the horizontal jaw position relationship in the mouth, thereby simplifying the intraoral operation.

[0115] It should be noted that before performing step S701, the dental occlusal recording device needs to be tried in the mouth to confirm that the device can be fully positioned and to check the occlusal condition. Only the lower front teeth should be in contact with the occlusal platform 20, and the other teeth should not be in occlusal contact.

[0116] If necessary, first use the dental bite recording device to deprogram the masticatory muscles. Exemplarily, the process of masticatory muscle deprogramming is: wear the dental bite recording device for 10-30 minutes to remove the influence of the original masticatory muscle contraction pattern when the upper and lower teeth are occluded on the subsequent determination of the jaw position. Of course, this step is optional and can be set according to needs, so it will not be repeated here.

[0117] In one embodiment provided in the present application, the method for determining the jaw position relationship by the anterior teeth guide 10 and the occlusal platform 20 in step S702 includes:

[0118] Instruct the patient to control the mandibular teeth to move forward and backward and sideways along the occlusal platform 20 and the anterior teeth guide 10, and use articulating paper to record the movement trajectory of the anterior teeth on the occlusal platform 20 and the anterior teeth guide 10;

[0119] Then ask the patient to repeat the bite with the upper and lower jaws naturally relaxed, and use another color of articulation paper to record the position of the lower front teeth on the occlusal platform 20 during habitual closure;

[0120] The horizontal jaw position relationship is determined based on the anterior-posterior and lateral movement trajectories and the habitual closed occlusal point.

[0121] According to the treatment concept or need, the habitual closed occlusal point, the vertex of the anterior-posterior and lateral movement trajectory, or a suitable position between the two can be selected as the determined lower anterior teeth occlusal position of the horizontal jaw position relationship. For example, a marker pen is used to mark the front of the determined position.

[0122] In one embodiment provided in the present application, the method of recording the patient's jaw position relationship by the posterior teeth recording unit 30 in step S703 includes:

[0123] The bite registration material is injected into the posterior tooth registration part 30, and the jaw position relationship of the upper and lower teeth is recorded using the bite registration material.

[0124] Exemplarily, after the bite recording material is injected into the posterior teeth recording part 30, the patient is asked to bite, and the patient can first make forward and backward and lateral movements, and then make the lower front teeth bite to the position determined in the previous step, and keep it stable until the bite recording material hardens. If necessary, the hardened bite recording material in the posterior teeth area is further trimmed so that it can stably record the horizontal jaw relationship of the upper and lower teeth without affecting the forward and backward and lateral movements of the lower jaw, thereby completing the operation of recording the horizontal jaw relationship.

[0125] Of course, the dental occlusal recording device completed above can be used to real-time the upper and lower jaw dentition models according to the determined jaw position relationship. The frame is set by using the front tooth guide 10 The frame cutting guide parameters can be used for subsequent restorative treatment process; it can also be combined with the mandibular movement trajectory tracing to connect the fully digital process.

[0126] The specific process of fully digitalizing the mandibular movement trajectory is as follows: the virtual bite record is obtained by intraoral scanning of the buccal surface data of the posterior teeth of the upper and lower dentition when the device is worn, and the patient is asked to wear the dental bite recorder to trace the mandibular movement trajectory. The measured mandibular movement data is used to map the upper and lower dentition data onto a personalized virtual The measured real mandibular movement data can be directly used for subsequent restoration design and production.
