Description

Technical Field

[0001] The utility model relates to the technical field of oral medical devices, and in particular to a mixed reality navigation orthodontic bracket bonding device. Background Art

[0002] Malocclusion, characterized by uneven teeth, poor bite, and disproportionate facial features, has a prevalence rate of 67.82% in my country. Fixed orthodontic technology, with its mature technology and effective correction, has become the primary treatment option for malocclusion. Data indicates that the traditional orthodontic market in my country is projected to exceed US$7 billion.

[0003] Fixed orthodontic treatment uses orthodontic brackets and orthodontic archwires bonded to the tooth surface to load orthodontic "force" to move teeth, adjust the jaw, and thus treat malocclusion. Among them, accurate positioning of bracket bonding is one of the key factors affecting the effectiveness and efficiency of orthodontic treatment. However, in clinical practice, especially for novice orthodontists, inaccurate positioning, slow operation, unstable jaw position and insufficient intraoral exposure during initial bonding and re-bonding are common problems, which consume a lot of chairside time and increase the orthodontic treatment costs for doctors and patients. Therefore, accurate, efficient and convenient bracket bonding is one of the keys to the success of fixed orthodontic treatment. Recently, a mixed reality (MR) navigation orthodontic bracket bonding system has provided an innovative approach to solving the above problems, but there is still a lack of a device that is compatible with the mixed reality navigation equipment when used in bonding operations and teaching and training scenarios. Utility Model Content

[0004] In response to the above problems, the purpose of the present utility model is to provide a mixed reality navigation orthodontic bracket bonding device, which cooperates with the MR navigation equipment through the QR code and surface recognition landmarks on the jaw pad to achieve rapid alignment and accurate positioning of the bracket; at the same time, through the jaw pad adapted to the tooth body and the openers on both sides of the lips, the upper and lower teeth are kept stable and more tooth surfaces are exposed, so as to better cooperate with the mixed reality navigation equipment and achieve accurate, efficient and convenient orthodontic bracket bonding.

[0005] The embodiments of the present invention are achieved through the following technical solutions:

[0006] A mixed reality navigation orthodontic bracket bonding device includes a jaw pad, wherein the upper and lower surfaces of the jaw pad are provided with tooth sockets adapted to the upper and lower dentitions of the model, a first connecting rod is connected to both sides of the jaw pad, an end of the first connecting rod away from the jaw pad is connected to an opener for opening the lips, the jaw pad is connected to a second connecting rod, an information plate is provided on the second connecting rod, a QR code is provided on the side of the information plate away from the jaw pad, and a number of identification mark points are provided on the surface of the QR code and the jaw pad.

[0007] Preferably, the jaw pad, the second connecting rod, the information plate, the QR code, and the identification mark are integrally formed by 3D printing, and the opener and the first connecting rod are integrally formed and then connected to the jaw pad.

[0008] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0009] The QR code and surface recognition landmarks on the jaw pad are used in conjunction with the MR navigation device to achieve rapid registration and accurate positioning of the brackets. At the same time, the jaw pad that matches the teeth and the openers on both sides of the lips can keep the upper and lower teeth stable and expose more tooth surfaces, thereby better cooperating with the mixed reality navigation device to achieve accurate, efficient and convenient orthodontic bracket bonding.

[0016] The following combination Figure 1 、 Figure 2 The utility model is described in detail.

[0017] Example

[0018] A mixed reality navigation orthodontic bracket bonding device includes a jaw pad 1. The upper and lower surfaces of the jaw pad 1 are provided with tooth sockets 6 adapted to the upper and lower dentition of the model. The two sides of the jaw pad 1 are connected to a first connecting rod 3. The end of the first connecting rod 3 away from the jaw pad 1 is connected to an opener 2 for opening the lips. The jaw pad 1 is connected to a second connecting rod 4. The second connecting rod 4 is provided with an information plate 5. The side of the information plate 5 away from the jaw pad 1 is provided with a QR code 8. Several identification mark points 7 are provided on the surface of the QR code 8 and the jaw pad 1.

[0019] The upper and lower surfaces of the jaw pad 1 are provided with tooth sockets 6 that are adapted to the upper and lower dentitions of the model. The upper and lower teeth of the model are just embedded in the tooth sockets 6. The opener 2 is supported on both sides of the lips to keep the position of the jaw pad 1 fixed, ensuring the stability of the upper and lower dentitions.

[0020] The jaw pad 1 has a certain thickness, which separates the upper and lower teeth, thereby exposing more tooth surfaces of the mandibular teeth. The opener 2 can also maintain the opening degree of the mouth, thereby exposing more tooth surfaces on both sides of the teeth and more space in the mouth, ensuring the normal bonding of the brackets.

[0021] The characteristic points of the jaw pad 1 (such as edges, corners, etc.) are recorded on the QR code 8; after the camera on the mixed reality device is used to scan the QR code 8 and identify the landmark point 7, the registration program in the mixed reality device is started, and the mixed reality (MR) device can create a three-dimensional virtual model of the jaw pad 1 and the bracket according to the information of the QR code 8 and accurately align the three-dimensional virtual model to a specific position and angle in the real world, and then automatically align the three-dimensional virtual model of the jaw pad 1 and the bracket with the model tooth or the physical tooth in the real scene, so that the virtual model and the model tooth or the physical tooth in the real scene are automatically aligned. Compared with the manual alignment of the operator, the accuracy of the alignment can be greatly improved and the alignment time can be shortened. The operation of automatically aligning after scanning the QR code of the above-mentioned mixed reality device is a prior art and will not be described in detail here.

[0022] In manual registration, the virtual environment is prone to floating when the operator moves, while in automatic registration, the virtual model is relatively fixed.

[0023] Afterwards, the operator or trainee performs the bracket bonding operation under the guidance of the three-dimensional virtual model of the bracket displayed on the MR device. Compared with naked-eye bonding, this can significantly improve the bracket positioning accuracy and success rate during initial bonding and re-bonding, and shorten the operation time.

[0024] The jaw pad 1, second connecting rod 4, information plate 5, QR code 8, and identification mark 7 are integrally formed via 3D printing. The mouth opener 2 and first connecting rod 3 are integrally formed and then connected to the jaw pad 1. The jaw pad 1 can be designed based on digitized intraoral data, with upper and lower occlusal surfaces adapted to natural teeth or model teeth, and then integrally 3D printed. Alternatively, a universal jaw pad with upper and lower occlusal surfaces can be designed based on digitized intraoral data, 3D printed, and silicone rubber stacked on its upper and lower occlusal surfaces. The jaw pad is then worn in the mouth, and the silicone rubber provides a shape that adapts to the dentition.

[0025] The identification mark point 7 on the jaw pad 1 can be designed as a separate circular mark point so that the mixed reality device can be better aligned. The cusp point of the model tooth or the real tooth can also be used as the identification mark point, which can also assist in achieving better alignment in the absence of the identification mark point 7.

[0026] The device of the present application can be used in orthodontic experimental training and teaching in dental schools and to assist in orthodontic bracket bonding operations in oral clinics.

[0027] 1. During the teaching and training of orthodontic bracket bonding:

[0028] First, print out a digital dental model and the device of the present application corresponding to the digital dental model, and import the virtual model into the mixed reality device;

[0029] The device is positioned in the corresponding position on the digital dental model, and the model is secured to a stable surface. The mixed reality headset is then activated to scan and recognize the QR code 8 and landmarks 7, which initiates the registration process within the mixed reality device. After the virtual and real models are automatically registered, the brackets are bonded to the real model using the MR device, guided by the virtual brackets.

[0030] 2. When performing oral operations for orthodontic bracket bonding:

[0031] First, perform an intraoral scan of the case to obtain a digital dental model;

[0032] Print out the digital dental model and the device of the present application corresponding to the digital dental model, and import the virtual model into the mixed reality device;

[0033] The device is placed in the patient's mouth, ensuring the model is firmly in place. The mixed reality headset scans and recognizes the QR code 8 and landmarks 7, initiating the registration process within the mixed reality device. Once the virtual model and the patient's dentition are automatically registered, the brackets are bonded to the patient's dentition in the real world, using the MR device and guided by the virtual brackets.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
