[0043] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.

[0044] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0045] With the rapid development of digital dentistry, more and more dental problems can be effectively solved. Jaw rest position serves as an important reference for prosthetics, such as denture design and maxillofacial adjustment. Research has found that related techniques include occlusal recording, joint analysis recording, and manual recording to measure the user's jaw rest position.

[0046] The occlusal recording method is to have the user being tested bite on the occlusal splint, and then have the user move the lower jaw up or forward until the user finds the most comfortable position, and then use a special wax block or marking pen to mark the resting jaw position of the user being tested on the occlusal splint. The joint analysis recording method is to use a joint analysis instrument to record the patient's resting jaw position, and determine the best resting jaw position by analyzing the movement and position of the temporomandibular joint. Manual recording method: Use a special recording paper or film, place a layer of film or recording paper between the upper and lower teeth of the user being tested, and then have the user being tested bite tightly, and then have the user move the lower jaw up and forward until the user finds the most comfortable position, and then use a special marking pen to mark the resting jaw position of the patient being tested on the film or recording paper.

[0047] When the above method is actually used to measure the resting jaw position, human intervention will be performed on the user being measured to keep the lower jaw in the correct resting jaw position, thereby affecting the measurement accuracy and interfering with the user's accurate and efficient tooth restoration.

[0048] In order to improve the efficiency and accuracy of determining the jaw rest position, embodiments of the present disclosure provide a method, apparatus, device, and storage medium for determining the jaw rest position.

[0049] The following describes the method for determining the jaw position at rest provided by an embodiment of the present disclosure in conjunction with Figures 1 to 4. In the embodiment of the present disclosure, the method for determining the jaw position at rest can be performed by an electronic device. The electronic device can include a device with communication capabilities, such as a tablet computer, a desktop computer, or a laptop computer, and can also include a device simulated by a virtual machine or simulator.

[0050] FIG1 shows a flow chart of a method for determining a resting jaw position provided by an embodiment of the present disclosure.

[0051] As shown in FIG1 , the method for determining the resting jaw position may include the following steps.

[0052] S110: Obtain dental data and facial data of the user being tested.

[0053] In this embodiment, when it is necessary to detect the resting jaw position of the user being measured, the dental data and facial data of the user being measured are collected respectively using a dental data acquisition device and a facial data acquisition device, so that the resting jaw position of the user being measured is determined by combining the dental data and the facial data.

[0054] Optionally, dental data collection devices include but are not limited to oral scan data, and facial data collection devices include but are not limited to facial scan devices. Dental data includes but is not limited to maxillary data, maxillary landmarks, mandibular data, and mandibular landmarks. Facial scan data includes but is not limited to the nasal tip point, prechin point, maxillary landmarks, and mandibular landmarks.

[0055] In some embodiments, several marking points are pasted on the upper and lower teeth of the user being tested. When the user being tested opens and closes his mouth, a dental data acquisition device is used to scan the upper and lower teeth, as well as the marking points on the upper and lower teeth of the user being tested, thereby obtaining dental data. At the same time, the user being tested wears a mouth expander with several marking points pasted on it. When the user being tested opens and closes his mouth, a facial data acquisition device is used to scan the upper and lower teeth, as well as the marking points on the upper and lower teeth of the user being tested, thereby obtaining facial data.

[0056] In other embodiments, while the user under test is opening and closing his mouth, a dental data acquisition device is used to scan the dental features on the maxillary teeth and the mandibular teeth of the user under test to collect image data, thereby obtaining dental data. At the same time, a facial data acquisition device is used to scan the dental features on the maxillary teeth and the mandibular teeth of the user under test to obtain facial data.

[0057] S120: Determine a real-time distance between a first measurement point and a second measurement point on the face of the measured user.

[0058] In this embodiment, before collecting the dental data and facial data of the user being measured, a first measurement point and a second measurement point are pasted on the face of the user being measured, and after collecting the dental data and facial data of the user being measured, the real-time distance between the first measurement point and the second measurement point is determined, so that it is judged whether the user being measured is in the resting jaw position based on the real-time distance.

[0059] The first measuring point and the second measuring point are used to measure the marking points of the measured user in the resting jaw position.

[0060] Optionally, the first measurement point is the tip of the nose of the measured user, and the second measurement point is the chin point of the measured user, or the first measurement point is the chin point of the measured user, and the second measurement point is the tip of the nose of the measured user.

[0061] The real-time distance includes but is not limited to the first upper and lower jaw distance when the user is in the resting jaw state, the second upper and lower jaw distance when the user is in the occluded jaw state, and the upper and lower jaw distance when the user is in any other state.

[0062] In this embodiment, specific implementations of S120 include but are not limited to the following: identifying a first measurement point and a second measurement point from the facial data; and calculating a real-time distance based on image data corresponding to the first measurement point and the second measurement point in the facial data.

[0063] Specifically, the electronic device can identify the first measurement point and the second measurement point based on user selection or automatic identification, and determine the image data corresponding to the first measurement point and the second measurement point respectively. The image data of each measurement point can be understood as coordinate data. Then, based on the image data corresponding to the first measurement point and the second measurement point respectively, the real-time distance between the first measurement point and the second measurement point is calculated.

[0064] S130: If the real-time distance is equal to the distance between the upper and lower jaws of the measured user in the resting jaw position, determine the resting jaw position of the measured user based on the dental data and the facial data.

[0065] In this embodiment, as described above, before collecting dental data and facial data of the user being measured, the first measurement point and the second measurement point are pasted on the face of the user being measured, so that the upper and lower jaws of the user being measured are in a completely still state under the guidance of a professional user. At this time, the dental and jaw state of the user being measured is in the resting jaw position state, and the distance between the upper and lower jaws of the user being measured when in the resting jaw position state can be determined by using a measuring tool or a facial data acquisition device.

[0066] Furthermore, after determining the real-time distance, it is determined whether the real-time distance is equal to the distance between the upper and lower jaws of the user being measured when the user is in the resting jaw position. If it is determined that the real-time distance is equal to the distance between the upper and lower jaws, it means that the user being measured is in the resting jaw position at this time, and the resting jaw position corresponding to the resting jaw position state is determined based on the dental data and facial data.

[0067] A method for determining the resting jaw position according to an embodiment of the present disclosure obtains dental data and facial data of a user being measured; determines the real-time distance between a first measurement point and a second measurement point on the user's face; and if the real-time distance is equal to the distance between the upper and lower jaws of the user being measured when the user is in the resting jaw position, determines the resting jaw position of the user being measured based on the dental data and the facial data. Thus, the resting jaw position of the user being measured is determined using a non-contact measurement method, which can reduce human interference and improve the efficiency and accuracy of determining the resting jaw position, thereby assisting the user in performing dental restorations accurately and efficiently.

[0068] In another embodiment of the present disclosure, the specific implementation process of “determining the resting jaw position of the measured user based on the dental data and the facial data” in S130 is explained in detail.

[0069] FIG2 shows a flow chart of another method for determining the jaw position at rest provided by an embodiment of the present disclosure.

[0070] As shown in FIG2 , the method for determining the resting jaw position may include the following steps.

[0071] S210: Obtain dental data and facial data of the user being tested.

[0072] S220: Determine a real-time distance between a first measurement point and a second measurement point on the face of the measured user.

[0073] Among them, S210 to S220 are similar to S110 to S120 and are not described in detail here.

[0074] S230: Map the tooth data from the first coordinate system to the target coordinate system, and map the facial data from the second coordinate system to the target coordinate system.

[0075] It is understandable that when a dental data acquisition device is used to scan a user, the coordinate system corresponding to the dental data acquisition device is the first coordinate system, and the dental data is located in the first coordinate system. When a facial data acquisition device is used to scan a user, the coordinate system corresponding to the facial data acquisition device is the second coordinate system, and the facial data is located in the second coordinate system. If the first coordinate system and the second coordinate system are different, the dental data and the facial data cannot be processed. For this reason, it is necessary to map the dental data from the first coordinate system to the target coordinate system, and to map the facial data from the second coordinate system to the target coordinate system, so that the dental data and the facial data can be processed in a unified target coordinate system.

[0076] Optionally, the target coordinate system may be the first coordinate system, the second coordinate system, or another coordinate system different from both the first coordinate system and the second coordinate system.

[0077] S240. In the target coordinate system, determine the resting jaw position of the measured user based on the dental data and facial data.

[0078] In this embodiment, specific implementations of S240 include but are not limited to the following: splicing the tooth data in the target coordinate system onto the facial data to determine the resting jaw position of the measured user.

[0079] In some embodiments, the dental data in the target coordinate system is spliced ​​onto the facial data to determine the resting jaw position of the user being measured. The specific implementation method is as follows: based on the dental landmark points of the user being measured, the dental data in the target coordinate system is spliced ​​onto the facial data to obtain the resting jaw position of the user being measured.

[0080] In some embodiments, the dental data in the target coordinate system is spliced ​​onto the facial data to determine the resting jaw position of the user being measured. The specific implementation method is as follows: based on the dental features of the user being measured, the dental data in the target coordinate system is spliced ​​onto the facial data to obtain the resting jaw position of the user being measured.

[0081] Specifically, both the dental data acquisition device and the facial data acquisition device can scan one of the dental landmarks and dental features of the user being measured, or both the dental data acquisition device and the facial data acquisition device can scan the dental landmarks and dental features of the user being measured. Therefore, the dental data in the target coordinate system can be spliced ​​onto the facial data, so that the dental data is aligned with the facial data, and the resting jaw position of the user being measured is determined.

[0082] Among them, tooth landmarks can be used to assist in splicing tooth data and facial data. For example, four landmarks are attached to the upper and lower teeth of the user being tested, and after the teeth of the user being tested are scanned using a tooth data acquisition device, multiple frames of scan data are obtained, that is, the tooth data containing landmarks shown in Figure 3 are obtained. At the same time, as shown in Figure 4, after the user being tested wears a mouth expander and several landmarks are attached to the upper and lower teeth of the user being tested, the facial data acquisition device is used to scan the upper and lower teeth of the user being tested, as well as the landmarks on the upper and lower teeth of the user being tested, thereby obtaining facial data. Then, based on the tooth landmarks, the tooth data in the target coordinate system is spliced ​​onto the facial data to determine the resting jaw position of the user being tested.

[0083] Among them, the tooth feature can be understood as the texture feature of the teeth of the user being measured, and the tooth data and facial data can be spliced ​​together.

[0084] Therefore, the resting jaw position of the measured user can be determined by combining the dental data and facial data of the measured user, thereby ensuring the efficiency and accuracy of determining the resting jaw position.

[0085] Furthermore, after determining the resting jaw position, the resting jaw position can also be displayed so that the resting jaw position can be used as reference data when performing tooth restoration on the measured user, so as to achieve the effect of assisting the user to perform tooth restoration accurately and efficiently.

[0086] Among them, the distance between the upper and lower jaws corresponding to the resting jaw position is the resting jaw distance. The resting jaw distance serves as a distance constraint condition when performing dental restoration on the user being tested, thereby providing the user with more reference data for dental restoration.

[0087] A specific explanation of the method for determining the resting jaw distance is as described above. Before collecting dental data and facial data of the user being measured, a first measurement point and a second measurement point are pasted on the face of the user being measured. The user being measured performs mouth opening and closing movements under the guidance of a professional user. When it is detected that the real-time distance is equal to the first upper and lower jaw distance when the user being measured is in the resting jaw position, the first upper and lower jaw distance is recorded. When it is detected that the real-time distance is equal to the second upper and lower jaw distance when the user being measured is in the occluded jaw position, the second upper and lower jaw distance is recorded. The first upper and lower jaw distance is subtracted from the second upper and lower jaw distance to obtain the upper and lower jaw distance corresponding to the resting jaw position, which is the resting jaw distance.

[0088] For ease of understanding, refer to the state diagram of the jaw rest position shown in Figure 5. When the user being measured is in the jaw rest position state, the jaw rest position of the user being measured can be determined based on the dental data and facial data, and the distance between the upper and lower jaws corresponding to the jaw rest position is the jaw rest distance.

[0089] Therefore, after the jaw rest position is determined, the jaw rest position and the jaw rest distance are intuitively displayed to the user, so as to assist the user in performing tooth restoration accurately and efficiently.

[0090] The present disclosure also provides a jaw position determination device for implementing the above-mentioned jaw position determination method, which is described below in conjunction with FIG6 . In the present disclosure, the jaw position determination device can be an electronic device. The electronic device can include a tablet computer, desktop computer, laptop computer, or other device with communication capabilities, or a device simulated by a virtual machine or simulator.
