[0042] 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 in the embodiments can be combined with each other without conflict.

[0043] 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.

[0044] With the rapid development of oral digitalization, more and more oral problems can be well solved. The resting jaw position is an important reference for dental restoration such as denture design and maxillofacial relationship adjustment. Studies have found that the relevant technologies include the occlusal recording method, joint analysis recording method and manual recording method to measure the resting jaw position of the measured user.

[0045] The occlusal recording method is to have the user bite on the occlusal plate, and then have the user move the lower jaw upward 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 on the occlusal plate. 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, then have the user bite tightly, and then have the user move the lower jaw upward and forward until the most comfortable position is found, and then use a special marking pen to mark the resting jaw position of the patient on the film or recording paper.

[0046] When the above method is actually used to measure the resting jaw position, human intervention will be performed on the user being measured, so that the lower jaw of the user being measured remains in the correct resting jaw position, thereby affecting the measurement accuracy and interfering with the user's accurate and efficient tooth restoration.

[0047] In order to improve the efficiency and accuracy of determining the jaw rest position, the embodiments of the present disclosure provide a method, an apparatus, a device and a storage medium for determining the jaw rest position.

[0048] Combine the following Figures 1 to 4 The method for determining the jaw position at rest provided by the embodiment of the present disclosure is described. In the embodiment of the present disclosure, the method for determining the jaw position at rest can be executed by an electronic device. The electronic device can include a device with communication functions such as a tablet computer, a desktop computer, a laptop computer, etc., and can also include a device simulated by a virtual machine or a simulator.

[0049] Figure 1 A schematic flow chart of a method for determining a resting jaw position provided by an embodiment of the present disclosure is shown.

[0050] like Figure 1 As shown, the method for determining the resting jaw position may include the following steps.

[0051] S110: Obtain the dental data and facial data of the user being tested.

[0052] 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.

[0053] Optionally, the dental data collection device includes but is not limited to oral scan data, and the facial data collection device includes but is not limited to face scan equipment. The dental data includes but is not limited to maxillary data, maxillary landmarks, mandibular data, and mandibular landmarks. The face scan data includes but is not limited to the nose tip point, the prechin point, the maxillary landmarks, and the mandibular landmarks.

[0054] In some embodiments, a number of 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 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, on which a number of marking points are pasted. When the user being tested opens and closes his mouth, a facial data acquisition device is used to scan the marking points on the upper and lower teeth of the user being tested, thereby obtaining facial data.

[0055] In other embodiments, when the user under test opens and closes 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 acquire 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.

[0056] S120: Determine a real-time distance between a first measurement point and a second measurement point on the face of the measured user.

[0057] In this embodiment, before collecting the dental data and facial data of the user under test, the first measurement point and the second measurement point are pasted on the face of the user under test, and after collecting the dental data and facial data of the user under test, the real-time distance between the first measurement point and the second measurement point is determined, so that it is judged whether the user under test is in the resting jaw position based on the real-time distance.

[0058] 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 state.

[0059] Optionally, the first measuring point is the tip of the nose of the user being measured, and the second measuring point is the chin point of the user being measured, or the first measuring point is the chin point of the user being measured, and the second measuring point is the tip of the nose of the user being measured.

[0060] 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 position, the second upper and lower jaw distance when the user is in the occluded jaw position, and the upper and lower jaw distance when the user is in any other state.

[0061] 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.

[0062] Specifically, the electronic device can identify the first measurement point and the second measurement point based on user selection or automatically, 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.

[0063] S130: If the real-time distance is equal to the distance between the upper and lower jaws of the measured user when the measured user is in the resting jaw position, determine the resting jaw position of the measured user based on the dental data and the facial data.

[0064] In this embodiment, as described above, before collecting dental data and facial data of the user under test, the first measurement point and the second measurement point are pasted on the face of the user under test, so that the upper and lower jaws of the user under test are in a completely still state under the guidance of a professional user. At this time, the dental and jaw state of the user under test is in a resting jaw position state. The distance between the upper and lower jaws of the user under test when in the resting jaw position state can be determined by measuring tools or facial data acquisition equipment.

[0065] 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 when the user being measured 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.

[0066] A method for determining the resting jaw position of an embodiment of the present disclosure obtains the dental data and facial data of the user being measured; determines the real-time distance between the first measuring point and the second measuring point on the face of the user being measured; 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, the resting jaw position of the user being measured is determined based on the dental data and the facial data. Thus, the resting jaw position of the user being measured is determined by 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 to perform tooth restoration accurately and efficiently.

[0067] 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.

[0068] Figure 2 A schematic flow chart of another method for determining the resting jaw position provided by an embodiment of the present disclosure is shown.

[0069] like Figure 2 As shown, the method for determining the resting jaw position may include the following steps.

[0070] S210: Obtain the dental data and facial data of the user being tested.

[0071] S220: Determine a real-time distance between a first measurement point and a second measurement point on the face of the measured user.

[0072] Among them, S210 to S220 are similar to S110 to S120 and are not described in detail here.

[0073] S230, mapping the tooth data from the first coordinate system to the target coordinate system, and mapping the facial data from the second coordinate system to the target coordinate system.

[0074] It is understandable that, in the process of scanning the user under test using the dental data acquisition device, 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. In the process of scanning the user under test using the facial data acquisition device, 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 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.

[0075] 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.

[0076] S240. In the target coordinate system, based on the teeth data and the facial data, determine the resting jaw position of the user being measured.

[0077] In this embodiment, the specific implementation of S240 includes but is not limited to the following methods: splicing the tooth data in the target coordinate system onto the facial data to determine the resting jaw position of the measured user.

[0078] 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.

[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 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.

[0080] 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 then the resting jaw position of the user being measured is determined.

[0081] Among them, the tooth landmarks can be used to assist in splicing the tooth data and the facial data. For example, four landmarks are attached to the upper and lower teeth of the user being tested, and the teeth of the user being tested are scanned by a tooth data acquisition device to obtain multiple frames of scan data, that is, Figure 3 The tooth data including the landmarks shown in the figure, meanwhile, Figure 4 As shown, after the user being tested can wear a mouth expander and a number of marking points are pasted on the upper and lower teeth of the user being tested, the facial data acquisition device is used to scan the upper and lower teeth, the mandibular teeth and the marking points on the upper and lower teeth of the user being tested to obtain facial data, and then the tooth data in the target coordinate system is spliced ​​onto the facial data based on the tooth marking points to determine the resting jaw position of the user being tested.

[0082] Among them, the tooth feature can be understood as the texture feature of the teeth of the user being tested, and the tooth data and facial data can be spliced.

[0083] 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.

[0084] Furthermore, after the resting jaw position is determined, 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.

[0085] 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 is used 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.

[0086] 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 to be measured, a first measuring point and a second measuring point are pasted on the face of the user to be measured, and the user to be measured performs 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 to be 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 to be measured is in the occluded jaw position, the second upper and lower jaw distance is recorded, and the first upper and lower jaw distance is subtracted from the second upper and lower jaw distance, and the upper and lower jaw distance corresponding to the resting jaw position is obtained as the resting jaw distance.

[0087] For easier understanding, see Figure 5 As shown in the schematic diagram of the jaw rest position state, 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.

[0088] Therefore, after the jaw resting position is determined, the jaw resting position and the jaw resting distance are intuitively displayed to the user, so as to achieve the effect of assisting the user to perform tooth restoration accurately and efficiently.

[0089] The present disclosure also provides a device for determining the jaw position at rest for implementing the above-mentioned method for determining the jaw position at rest. Figure 6 In the disclosed embodiment, the device for determining the resting jaw position may be an electronic device, which may include a tablet computer, a desktop computer, a laptop computer, or other device with a communication function, or a device simulated by a virtual machine or a simulator.

[0094] The second determination module 630 is used to determine the resting jaw position of the measured user based on the tooth data and the facial data if the real-time distance is equal to the distance between the upper and lower jaws of the measured user when the measured user is in the resting jaw position.
