Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a digital occlusal guide for use in pediatric general anesthesia dental surgery, and more particularly to a method for manufacturing a digital occlusal guide for use in pediatric general anesthesia dental surgery. Background Technology

[0002] As is well known, occlusal splints are an effective treatment for temporomandibular joint dysfunction syndrome. They can relieve symptoms of the temporomandibular joint and maxillofacial muscles, and have good effects on eliminating clicking, reducing pain, treating bruxism and other joint and muscle diseases.

[0003] However, the occlusal guides currently used in pediatric general anesthesia dental surgery still have some problems:

[0004] I. Pediatric dental treatment under general anesthesia is the best way to resolve severe caries in young children in one procedure. During the procedure, there is a high probability of needing to wear multiple preformed metal crowns at the same time. Because it is difficult to check the child's bite under general anesthesia, the postoperative bite status is uncertain and bite interference often occurs.

[0005] Second, in the existing technology, the malocclusion of the child after surgery will self-correct within a few months. During these months, the child will feel pain due to malocclusion discomfort, and it may even cause malocclusion.

[0006] Third, in the existing technology, silicone rubber is used to record the patient's bite status before the operation in order to check the bite during the operation. However, because the material is soft, it is dangerous to use it in the mouth of children under general anesthesia. Moreover, it can only solve the problem of excessive bite, but it is ineffective in the case of excessive bite. Summary of the Invention

[0007] The purpose of this invention is to provide a digital occlusal guide for use in pediatric general anesthesia dental surgery and its manufacturing method, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a digital occlusal guide for use in pediatric general anesthesia dental surgery, comprising: a first occlusal guide and an occlusal examination mechanism;

[0009] The occlusion inspection mechanism is used to determine whether the digital occlusion guide plate and the SSC are accurately positioned, and to confirm whether the occlusion and the results of indirect repair are consistent.

[0010] The bite inspection mechanism includes a second bite guide plate, which is disposed on one side of the first bite guide plate. A second inspection hole is provided on the outer side of the first bite guide plate, and a third inspection hole is provided on the outer side of the second bite guide plate. A groove is provided on the outer side of the first bite guide plate, and a first inspection hole is provided inside the groove. Both the first bite guide plate and the second bite guide plate are provided with bite grooves.

[0011] By adopting the above technical solution, a first inspection hole, a second inspection hole, and a third inspection hole are respectively opened in the first occlusal guide plate and the second occlusal guide plate to determine whether the digital occlusal guide plate and the SSC are accurately positioned. The first occlusal guide plate and the second occlusal guide plate are used together to make the occlusal guidance function of this solution on the teeth more comprehensive.

[0012] In addition, the present invention also provides a method for manufacturing a digital occlusal guide for use in pediatric general anesthesia dental surgery, comprising the following steps:

[0020] Preferably, in S2, when pouring the plaster model of the first occlusal guide plate and the second occlusal guide plate, multiple occlusal inspection mechanisms are provided.

[0021] Preferably, the bite inspection mechanism includes a first inspection hole, a second inspection hole, a groove, and a third inspection hole.

[0022] Preferably, in S4, when manufacturing the engagement guide plate, there are multiple SSC guiding structures. The guiding structures are adapted to the external shape of the SSC and provide good constraint and guidance for the positioning of the SSC.

[0023] Preferably, in S5, when the software manufactures the digital occlusal guide plate, it is designed by dividing it into four quadrants: upper, lower, left, and right, to avoid interference from the mouth opener during the guide plate placement process.

[0024] Preferably, in S6, the first and second engagement guide plates are made of a hard, non-deformable material, so that the guide plates can accurately guide and constrain the positioning of the SSC.

[0025] Preferably, in S7, the occlusion inspection mechanism can accurately determine whether the digital occlusion guide and SSC are accurately positioned, further ensuring consistency between the occlusion and the results of indirect repair.

[0026] Preferably, in S7, by placing adhesive material into the SSCs and initially positioning them, the SSCs are finally positioned by applying pressure with an interlocking plate.

[0042] like Figures 1-5 As shown, the bite inspection mechanism consists of a second bite guide plate 5, which is disposed on one side of the first bite guide plate 1. A second inspection hole 4 is provided on the outer side of the first bite guide plate 1, a third inspection hole 6 is provided on the outer side of the second bite guide plate 5, a groove 3 is provided on the outer side of the first bite guide plate 1, a first inspection hole 2 is provided inside the groove 3, and bite grooves 7 are provided on both the first bite guide plate 1 and the second bite guide plate 5.

[0043] The principle of the occlusion examination mechanism: The first occlusion guide plate 1 and the second occlusion guide plate 5 in this scheme have multiple SSC guiding structures. The guiding structures are adapted to the external shape of the SSC and can provide good constraint and guidance for the SSC's positioning. By opening the first inspection hole 2, the second inspection hole 4 and the third inspection hole 6 in the first occlusion guide plate 1 and the second occlusion guide plate 5 respectively, it is used to determine whether the digital occlusion guide plate and the SSC are accurately positioned and to confirm whether the occlusion and the result of indirect restoration are consistent. The second occlusion guide plate 5 is set and installed on one side of the first occlusion guide plate 1. The first occlusion guide plate 1 and the second occlusion guide plate 5 are used together to make the occlusion guidance effect of this scheme on the teeth more comprehensive.

[0044] Example 2

[0045] Please see Figure 2 and Figure 6 This invention provides a method for manufacturing a digital occlusal guide for use in pediatric general anesthesia dental surgery, comprising the following steps:

[0046] S1. Take an alginate impression from the child's mouth, use wax to restore and record the child's vertical distance;

[0047] S2. Pour the plaster mold and attach the frame;

[0048] S3. Perform SSC indirect restoration of the affected tooth on a plaster model;

[0049] S4. After spraying powder, sweep the plaster model with SSCs, export and save it in STL format;

[0050] S5. Use software to design a digital bite guide plate, which is divided into four parts and has an inspection structure;

[0051] S6. Use a 3D printer to create a digital bite guide plate;

[0052] S7. During general anesthesia, the SSC is tried on under the guidance of the occlusal plate, and the abutment teeth are adjusted accordingly until the guide plate and SSC are fully in place.

[0053] Specifically, in S2, when pouring the plaster model of the first occlusal guide plate 1 and the second occlusal guide plate 5, multiple occlusal inspection mechanisms are set up.

[0054] Specifically, the bite inspection mechanism includes a first inspection hole 2, a second inspection hole 4, a groove 3, and a third inspection hole 6.

[0055] Specifically, in S4, when manufacturing the engagement guide plate, there are multiple SSC guiding structures. The guiding structures are adapted to the external shape of the SSC and provide good constraint and guidance for the positioning of the SSC.

[0056] Specifically, in S5, when the software manufactures the digital bite guide plate, it is designed by dividing it into four quadrants: upper, lower, left, and right, to avoid interference from the mouth opener during the guide plate placement process.

[0057] Specifically, in S6, the first engagement guide plate 1 and the second engagement guide plate 5 are made of a hard and non-deformable material, so that the guide plates can accurately guide and constrain the positioning of the SSC.

[0058] Specifically, in S7, the occlusion inspection mechanism can accurately determine whether the digital occlusion guide and SSC are accurately positioned, further ensuring consistency between the occlusion and the results of indirect repair.

[0059] Specifically, in S7, adhesive material is placed into the SSCs and initially positioned, and then the SSCs are finally positioned by applying pressure using an interlocking plate.

[0060] Based on the above technical solution, the work steps of this solution are summarized as follows: An alginate impression is taken from the child's mouth; the vertical distance is restored and recorded using wax; a plaster model is poured and an articulator is placed; the SSC indirect restoration of the affected tooth is performed on the plaster model; after powder spraying, the plaster model containing the SSCs is scanned, exported and saved in STL format; a digital occlusal guide plate is designed using software, consisting of four parts and including examination structures; the digital occlusal guide plate is fabricated using a 3D printer; under general anesthesia, the SSCs are tried on under the guidance of the occlusal guide plate, and corresponding adjustments are made to the abutment teeth. The procedure involves adjusting the guide plate and SSCs until they are fully in place. Adhesive material is then placed into the SSCs for initial positioning. The occlusal plate is used to apply pressure and guide the SSCs into final positioning. Simultaneously, intraoperative structural examination can accurately determine whether the digital occlusal guide plate and SSCs are accurately positioned, further ensuring consistency between the occlusion and the results of indirect repair. The digital occlusal guide plate is designed with four quadrants: upper, lower, left, and right, avoiding interference from the mouth opening device during guide plate positioning. Due to its small size, the guide plate provides a good structural field of view for occlusal examination, ensuring accurate and rapid positioning and ease of use.

[0061] In summary: In this approach, the occlusal guide includes multiple structures for occlusal examination. During the procedure, these structures can be used to accurately determine whether the digital occlusal guide and the SSC are properly positioned, further ensuring consistency between the occlusal and indirect repair results. This approach can thus resolve the problem of occlusal interference.

[0062] In this design, the digital occlusal guide plate is divided into four quadrants: upper, lower, left, and right. This design avoids interference from the mouth opening device during the guide plate placement process and improves surgical safety.

[0063] In this solution, a digital bite guide plate is made of a rigid and non-deformable material, which can accurately guide and constrain the positioning of the SSC, avoiding the problems of deformation and insufficient constraint force of soft materials.

[0064] In this design, the occlusal guide plate has multiple SSC guiding structures, which are adapted to the external shape of the SSC and can provide good constraint and guidance for the SSC's positioning.

[0065] All parts not described in this invention are the same as or can be implemented using existing technology. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
