Description

Technical Field

[0001] The invention relates to the field of medical instruments, and in particular to an orthodontic orthognathic surgery positioning device. Background Art

[0002] With the development of economy and social concepts, orthodontic and orthognathic combined treatment is increasingly accepted by patients with skeletal malocclusion. However, due to the traction of soft tissues such as muscles and skin, partial occlusal interference and other factors, even with strong internal fixation, the jaw relationship after surgery is not very stable, and there is often a risk of recurrence. Currently, the method used is mostly intermaxillary elastic traction, which allows patients to eat normally and practice opening their mouths, but its ability to fix the position of the upper and lower jaws is poor, and because the traction position is often closer to the back of the mouth, it is difficult for patients to change the traction ring every day by themselves amid postoperative swelling and pain, and the expected ideal effect cannot be achieved.

[0003] In addition to the rapid changes in bones caused by orthognathic surgery, the local acceleration caused by intraoperative trauma can also make teeth move quickly in a short period of time. The relatively new "surgery first" treatment method uses this phenomenon to greatly shorten the entire orthodontic treatment course. "Block osteotomy" and other procedures make it possible for the entire bone block including the teeth to move relative to each other, thereby closing the tooth extraction gap more quickly. Therefore, we propose that the postoperative orthodontic sequence of "block osteotomy" performed in a surgery-first manner is: first quickly close the tooth extraction gap, and then align and level the entire dentition, so as to maximize the surgical effect and shorten the total treatment course.

[0004] If the surgery also involves cortical bone incisions at certain specific tooth positions, the rapid remodeling effect brought about by the local acceleration phenomenon can also provide a good preventive and therapeutic effect on the hidden dangers of local bone fenestration bone cracks or existing bone fenestration bone cracks.

[0005] However, due to the surgical trauma, patients often have limited mouth opening, swollen lips and face, and severe pain in the short term, making them unable to undergo more complex orthodontic clinical operations and thus missing the best opportunity for postoperative force application.

[0006] In summary, the key to the success of orthodontic and orthognathic combined treatment is to be able to stabilize the jaw relationship after surgery and to apply force to the teeth and bone fragments early. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The following is combined with Figures 1 to 5 , some embodiments of the present invention are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0040] A positioning device for orthodontic orthognathic surgery comprises a first positioning tooth plate 1 and a first positioning baffle 2; the first positioning tooth plate 1 is arc-shaped, and a plurality of first tooth sockets 1-1 corresponding to the tooth positions are arranged on the upper side of the first positioning tooth plate 1; the first positioning baffle 2 is arranged on the upper side of the first positioning tooth plate 1 and on the outer side of the first positioning tooth plate 1; a plurality of first positioning holes 2-2 are arranged on the first positioning baffle 2.

[0041] Specifically, in this embodiment, the first positioning tooth plate 1 is arc-shaped, and its arc-shaped structure is similar to the position of human teeth, which can enable the first tooth socket 1-1 to be arranged corresponding to the teeth on the gums, thereby fixing the position of the teeth and ultimately playing the role of orthodontic correction of the teeth.

[0042] The first positioning baffle 2 is arranged on the outer side of the arc, so that the first positioning baffle 2 can be arranged on the outer side of the teeth when in use.

[0043] When in use, the first positioning baffle 2 is hung on the orthodontic anchorage nail set on the jawbone through the first positioning hole 2-2 to achieve positioning and fixation of the overall positioning device; multiple first tooth sockets 1-1 are installed on the teeth in a one-to-one correspondence with the teeth to achieve correction positioning of the tooth position.

[0044] More specifically, in this embodiment, the shape of the first positioning dental plate 1 matches the shape of the patient's gums, and is the shape of the corrected gums; the position of the first dental alveolar 1-1 matches the position of the patient's corrected teeth.

[0045] More specifically, a plurality of orthodontic anchorage nails are nailed on the mandible, and a plurality of first positioning holes 2-2 are matched with the plurality of orthodontic anchorage nails respectively, and are arranged one by one, and the spacing between adjacent first positioning holes 2-2 is slightly different from the spacing between the corresponding adjacent orthodontic anchorage nails, so that the first positioning baffle 2 can be hung on the orthodontic anchorage nail through the first positioning hole 2-2, and the first positioning baffle 2 can be fixed on the orthodontic anchorage nail by generating tensioning force through different spacings.

[0046] In a preferred embodiment of the present invention, a first tooth mark groove 2 - 1 is provided on the inner side of the first positioning baffle 2 .

[0047] To ensure the accuracy of the first tooth groove 1-1, in this embodiment, a plurality of first tooth mark grooves 2-1 are arranged on the inner side of the first positioning baffle 2. The first tooth mark grooves 2-1 are against the outer side of the teeth, so that the first positioning baffle 2 can fit with the outer side of the teeth, which can not only achieve a better positioning effect, but also ensure the stability of positioning.

[0048] In a preferred embodiment of the present invention, first tooth sockets 1 - 1 are disposed on opposite sides of the first positioning tooth plate 1 .

[0049] In this embodiment, after the first tooth sockets 1 - 1 are provided on opposite sides of the first positioning tooth plate 1 , the upper and lower teeth in the mouth can be positioned simultaneously through the first positioning tooth plate 1 .

[0050] In a preferred embodiment of the present invention, first positioning baffles 2 are provided on opposite sides of the first positioning tooth plate 1 .

[0051] In this embodiment, first positioning baffles 2 are provided on both the upper and lower sides of the first positioning tooth plate 1, which are respectively abutted against the outer side surfaces of the upper teeth and the lower teeth, and a second positioning hole 3-2 is provided on the first positioning baffle 2. Through the first positioning hole 2-2 and the second positioning hole 3-2, the entire positioning device is positioned and fixed by cooperating with the orthodontic anchorage nails above and below the mandible respectively.

[0052] In a preferred embodiment of the present invention, the first positioning tooth plate 1 is provided with ventilation holes 1 - 2 , and the ventilation holes 1 - 2 pass through both inner and outer sides of the first positioning tooth plate 1 .

[0053] The provision of the vent holes 1-2 can prevent the patient from feeling stuffy when using the device, thereby ensuring smooth breathing.

[0054] Specifically, in this embodiment, there are multiple vent holes 1-2, and the specific number is set according to actual conditions, and is normally 3-5.

[0055] More specifically, in this embodiment, the ventilation holes 1 - 2 are circular holes.

[0056] In a preferred embodiment of the present invention, the orthodontic orthognathic surgery positioning device also includes a second positioning tooth plate 4, which is arranged on the lower side of the first positioning tooth plate 1, and the lower side of the second positioning tooth plate 4 is provided with a plurality of second tooth sockets corresponding to the tooth positions; a second positioning baffle 3 is provided on the outer side of the lower side of the second positioning tooth plate 4, and a plurality of second positioning holes 3-2 are provided on the second positioning baffle 3, and a plurality of second tooth mark grooves 3-1 are provided on the second positioning baffle 3.

[0057] In this embodiment, the upper teeth and the lower teeth are positioned separately, that is, the first positioning tooth plate 1 and the first positioning baffle plate 2 are used to position the upper teeth, and the second positioning tooth plate 4 and the second positioning baffle plate 3 are used to position the lower teeth. This arrangement enables the mouth to open and close after the upper teeth and the lower teeth are positioned, and normal language expression can be performed.

[0058] In a preferred embodiment of the present invention, a first traction device 5 is provided on the first positioning tooth plate 1 , and a second traction device 7 is provided on the second positioning tooth plate 4 ; the first traction device 5 and the second traction device 7 are connected by a traction rope 6 .

[0059] Specifically, in this embodiment, the first traction device 5 and the second traction device 7 are both hanging nails, and the two hanging nails are connected by a traction rope 6 to achieve position adjustment of the first tooth socket 1-1 and the second tooth socket at corresponding positions on the first positioning tooth plate 1 and the second positioning tooth plate 4.

[0060] In a preferred embodiment of the present invention, the traction rope 6 is a rubber band or an elastic rope.

[0061] It should be pointed out that the traction rope 6 can be a rubber band or an elastic rope, but it is not limited to these two types. It can also be other rope structures, such as a cotton rope, etc., as long as it can achieve the connection between the first traction device 5 and the second traction device 7.

[0062] In a preferred embodiment of the present invention, the first positioning baffle 2 is made of elastic material.

[0063] The first positioning baffle 2 is made by an elastic device, and the elastic force can ensure that the teeth do not feel strong discomfort when they fit on the first positioning baffle 2, thereby ensuring comfort during use. In addition, through the setting of the elastic device, when the first positioning hole 2-2 on the first positioning baffle 2 is hung with the orthodontic anchorage nail, the elasticity of the first positioning baffle 2 can be used to improve the positioning strength.

[0064] In a preferred embodiment of the present invention, the first positioning tooth plate 1 is made of elastic material.

[0065] In this embodiment, the material of the first positioning tooth plate 1 is an elastic material, which can enable the first tooth socket 1 - 1 on the first positioning tooth plate 1 to have a certain correction effect when it cooperates with the teeth.

[0066] Specifically, when the position of the teeth needs to be corrected, the position of the first alveolar 1-1 will not completely correspond to the position of the teeth, but will have a slight deviation. Since the first positioning tooth plate 1 has a certain elasticity, the teeth can still enter the first alveolar 1-1, and since there is a certain deviation between the teeth and the first alveolar 1-1, the first alveolar 1-1 will have a correction elastic force on the teeth, and the teeth are corrected to the final position through the correction elastic force.

[0067] The orthodontic orthognathic surgery positioning device of the present invention can be specifically divided into the following three usage modes:

[0068] (I) Mandibular bone positioning device for orthognathic surgery

[0069] It consists of a navigation plate that completely covers the upper and lower anterior teeth and the attached gingiva area of ​​the anterior teeth, the occlusal surface of the posterior teeth, and the connector between the upper and lower jaws.

[0070] (ii) Used as a force-adding device for stabilizing jaw relationship and teeth and bone blocks in the early stage after orthognathic surgery

[0071] It includes a series of bracketless invisible orthodontic devices that completely cover the upper and lower teeth and the upper and lower jaw attached gingival areas, and the corresponding upper and lower jaw connectors. The connector area is provided with vents 1-2 to ensure that breathing is not affected when necessary.

[0072] (III) Used as a tooth force and intermaxillary traction device in the late stage of orthognathic surgery

[0073] It includes a series of bracketless invisible orthodontic devices that completely cover the upper and lower teeth. Traction devices are designed on the labial and buccal surfaces of each tooth to facilitate the placement of intermaxillary traction rubber bands when necessary.

[0074] The entire device is designed with computer aids and formed in one go using 3D printing technology using bracketless invisible orthodontic materials.

[0075] The present invention provides an orthodontic orthognathic surgery positioning device, which is designed and manufactured as follows:

[0076] 1: According to the surgical design, orthodontic anchorage nails are implanted in the anterior and posterior areas of the upper and lower jaws of the patient in advance;

[0077] 2: Perform a three-dimensional laser intraoral scan of the complete maxillary and mandibular dentition, attached gingiva, free gingiva, vestibule groove and orthodontic anchorage pins, and a cone beam CT scan of the same occlusal position. Use computer software to build a three-dimensional model, and use three-dimensional modeling software to perform digital surgery and postoperative orthodontic design to determine the jaw and tooth positions that should be achieved immediately and one month after surgery.

[0078] 3: Based on the immediate postoperative 3D model, use the materials of the bracketless correction device and 3D printing technology to produce an integrated intraoperative positioning navigation plate and connector;

[0079] 4: Based on the immediate postoperative 3D model and the 3D model of the expected effect 20 days after surgery, use 3D modeling software to simulate the position of teeth and bone blocks every 2 days after surgery, and print out a series of occlusal models including mandibular anchorage nails;

[0080] 5: Use the series of occlusal models in step 4 to 3D print and produce a bracketless invisible orthodontic device (including the maxillomandibular connector) including the maxillomandibular position relationship represented by the maxillomandibular orthodontic anchorage pins.

[0081] 6: Based on the 3D model of the expected effect 20 days after surgery in step 4, continue to use the 3D modeling software to simulate the tooth position every 7 days thereafter, and print out a series of occlusal models;

[0082] 7: Use the series of occlusal models in step 6 to 3D print and produce upper and lower bracketless invisible orthodontic devices with traction devices on the labial and buccal surfaces of each tooth, wherein the traction devices on the upper and lower teeth are the first traction device 5 and the second traction device 7 respectively.

[0083] The beneficial effects of the present invention are:

[0084] (1) The positioning navigation plate during orthognathic surgery completely surrounds the anterior teeth, the labial jaw bone of the anterior teeth area, and the posterior occlusal surface. The upper and lower jaw orthodontic anchorage pins are used as the undercut fixation points, eliminating the need for traditional plates to be repeatedly ligated to the upper and lower jaw dentition, effectively shortening the operation time.

[0085] (2) The use of removable bracketless invisible braces avoids the need for preoperative bonding of brackets, saving orthodontic clinical operation time and also avoiding the possibility of interference between brackets and traditional bite plates. The absence of orthodontic devices such as brackets and archwires in the mouth also avoids the risk of devices falling into the wound or aspiration during surgery.

[0086] (3) The device is small in size in the oral cavity and can be removed and put on by the patient without opening the mouth too wide, which does not affect normal eating. The presence of the vents 1-2 on the connector of the early correction device also ensures smooth breathing when necessary.

[0087] (4) The orthodontic anchorage nail serves as a marker for bone movement and also as a marker for undercut retention, making it easier for the device to be fully seated without the need for auxiliary facilities such as chewing gum;

[0088] (5) The device can be worn immediately after waking up from anesthesia after surgery, which can maintain the surgical effect to the greatest extent. The presence of the early device connector can fix the position of the upper and lower jaws, avoiding the displacement or restoration trend of the jaw bone blocks caused by the traction of soft tissues such as muscles and skin; at the same time, the presence of the early device connector can separate the upper and lower teeth, avoiding the displacement or restoration trend of the jaw bone blocks caused by occlusal interference;

[0089] (6) The device can be worn immediately after waking up from anesthesia after surgery, which can maximize the "local acceleration phenomenon" brought about by the surgery, so that teeth and bones can be moved as soon as possible, effectively shortening the orthodontic treatment course;

[0090] (7) In the later stage, the orthodontic device adopts a design that separates the upper and lower jaws, and a traction device is designed on the labial and buccal surfaces of each tooth, so that elastic bands can be placed to perform inter-maxillary traction when necessary.

[0091] The treatment method using the surgical positioning and postoperative early correction device for orthodontic and orthognathic combined treatment is performed in the following steps:

[0092] Preparation process:

[0094] (2) Use 3D laser scanning to obtain the intraoral images of the patient, including the upper and lower dentition, attached gingiva on the labial and palatal sides, palatal vault, transitional groove, and orthodontic anchorage pins; perform cone beam CT scanning at the same occlusal position to obtain a 3D model of the entire craniofacial structure; use computer software to integrate the graphics to obtain a 3D model of the maxillofacial region;

[0095] (3) According to the surgical plan, the osteotomy line was designed using 3D modeling software to generate a 3D model of the entire craniofacial area after movement;

[0096] (4) According to the surgical plan and the three-dimensional model of the entire craniofacial structure after the movement, a bracketless invisible orthodontic material is used to design and 3D print a device that completely covers the tooth surfaces of the upper and lower anterior teeth, the upper and lower anterior gingival margins, the labial and buccal gingivae of the 6 implant pins in the upper and lower anterior teeth area, the 6 implant pins in the upper and lower anterior teeth area, and the first positioning baffle plate 2 and the second positioning baffle plate 3 covering the posterior occlusal surface, and a first positioning tooth plate 1 with a thickness of about 1-2 mm is designed to connect the upper and lower navigation plates into a whole;

[0097] (5) Use virtual tooth arrangement software to design the occlusal relationship to be achieved 20 days after surgery, simulate the occlusal condition every 2 days, and use 3D printing technology to print 10 sets of occlusal models;

[0098] (6) Based on the 10 occlusal models in (5), 10 sets of postoperative correction devices were 3D printed using bracketless invisible correction materials, which completely covered the entire maxillary and mandibular dentition, the labial and buccal gingiva from the maxillary and mandibular gingival margin to the 10 implants, and the 10 implants in the maxillary and mandibular. A horizontal connecting plate with a thickness of about 1-2 mm was designed to connect the maxillary and mandibular correction devices into a whole.

[0099] Taking bimaxillary surgery as an example, the following describes the method for using the intraoperative positioning and postoperative correction device of the present invention.

[0100] (1) Provide necessary retention and force attachments for the patient's tooth surface before surgery;

[0101] (2) Disinfection and sterilization of intraoperative positioning and postoperative correction devices;

[0102] (3) The maxilla is severed according to the surgical plan, the intermediate intraoperative positioning device is inserted into the mandible and maxilla, the maxilla is firmly fixed, the intermediate intraoperative positioning device is removed, the mandible is severed, the final intraoperative positioning device is inserted, and the mandible is firmly fixed;

[0103] (4) After the patient wakes up from anesthesia, put on the first postoperative correction device;

[0104] (5) After surgery, replace a pair of postoperative correction devices every 2 days, ensuring that 10 orthodontic anchorage pins are in place in the upper and lower jaws each time;

[0105] (6) After wearing 10 sets of early orthodontic appliances in sequence, start wearing slightly later orthodontic appliances in sequence, changing one set every 7 days, and ensure that the retention and force-applying accessories on the tooth surface are in place each time.

[0106] The beneficial effects of the embodiments of the present invention are:

[0107] The teeth are positioned on the first positioning dental plate 1 through the first alveolar 1-1 on the first positioning dental plate 1, thereby realizing the relative positioning between the first alveolar 1-1, and then the first positioning dental plate 1 is set on the jawbone through the first positioning baffle 2, so that the teeth can be stably set on the jawbone, thereby ensuring the effect of orthodontic and orthognathic combined treatment.

[0108] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
