Abstract
Description
Technical Field
[0001] This utility model relates to the field of oral medicine surgery technology, specifically a support and positioning guide structure for extracting impacted teeth. Background Technology
[0002] Impacted teeth, also known as embedded teeth, are teeth that have not erupted from the jawbone despite having already erupted. Clinically, they are most commonly found in the third molars, followed by the maxillary canines, second premolars, and extra teeth, with an incidence rate exceeding 20%. They often require surgical extraction. Because impacted teeth are covered by structures such as the gums and alveolar bone, positioning them during extraction is difficult, requiring a large surgical incision and significant bone removal. Furthermore, they are prone to damaging adjacent tooth roots, nerves, and other important anatomical structures, making extraction challenging and prone to complications, causing considerable distress for both patients and surgeons.
[0003] Existing surgical guides, through digital and 3D printing technology, can precisely guide the surgical area, reducing surgical difficulty and trauma. However, the production cycle takes about one week and the cost is high, sometimes exceeding the cost of the surgery itself. At the same time, digital guides require high-end equipment such as 3D printers and dental scanners, which represent a huge expense for many grassroots medical institutions, thus limiting the promotion and use of digital guides. Utility Model Content
[0004] In order to overcome the defects of the existing technology, the purpose of this utility model is to provide a support and positioning guide plate structure for extracting impacted teeth, so as to solve the technical problem of low accuracy of imaging and positioning of impacted teeth in the existing technology.
[0005] This utility model is achieved through the following technical solution:
[0006] A support and positioning guide structure for extracting impacted teeth, which is worn in the patient's oral cavity to locate the impacted teeth under CT irradiation, the support and positioning guide structure includes a jaw pad body;
[0007] The jaw pad body includes a buccal plate located in front of the dental arch and a palatal plate located behind the dental arch; the ends of the buccal plate and the palatal plate are connected by a base plate; the base plate abuts against the top of the dental arch; the surfaces of the buccal plate and the palatal plate are respectively provided with positioning structures, which are used to position the impacted teeth on the surfaces of the buccal plate and the palatal plate under CT irradiation.
[0008] Preferably, the positioning structure consists of several positioning holes, which are distributed on the buccal and palatal lateral plates and are all disposed through the plates of the buccal and palatal lateral plates. A positioning post is inserted into each of the positioning holes.
[0009] Furthermore, all of the positioning holes are of equal size.
[0010] Furthermore, the diameter of the positioning hole corresponds to the outer diameter of the positioning post.
[0011] Furthermore, several positioning holes are correspondingly set at the positions of the buccal and palatal lateral plates.
[0012] Preferably, the structure of the jaw pad body corresponds to the structure of the oral dentition, wherein the structure of the buccal plate corresponds to the buccal structure of the oral dentition, and the structure of the palatal plate corresponds to the palatal structure of the oral dentition.
[0013] Furthermore, the buccal plate includes an integrally formed labial plate and two sets of buccal rows, wherein the two sets of buccal rows are located on both sides of the labial plate.
[0014] The labial plate corresponds to the labial position of the oral dentition, and the two buccal plates correspond to the buccal positions of the oral dentition.
[0015] Preferably, the width of the base plate corresponds to the width of the dental arch in the mouth.
[0016] Preferably, the material of the jaw pad body is a thermoplastic material.
[0017] Compared with the prior art, the present invention has the following beneficial technical effects:
[0018] This invention provides a support and positioning guide structure for extracting impacted teeth. The ends of the buccal and palatal plates are connected to a base plate, which abuts against the ends of the tooth row, allowing the occlusal pad to effectively fit against the oral cavity tooth row. Positioning structures are provided on the surfaces of both the buccal and palatal plates. Under CT irradiation, the impacted teeth can be visualized on the surfaces of the buccal and palatal plates. The positioning structures can determine the specific location of the impacted teeth, improving the accuracy of imaging and positioning of impacted teeth.
[0019] Furthermore, the positioning structure consists of several positioning holes, which are distributed on the buccal and palatal lateral plates and penetrate through the plates. Positioning posts are inserted into each of the positioning holes. By inserting the positioning holes into the positioning holes, the impacted tooth can be clearly visualized on the buccal and palatal lateral plates under CT irradiation. The specific location of the impacted tooth is then determined by the positioning holes covered by the impacted tooth in the visualization. After removing the positioning posts in the positioning holes of the impacted tooth, it is convenient to remove the impacted tooth in the patient's oral cavity.
[0020] Furthermore, the size of the positioning holes is equal, which facilitates the accurate positioning of the impacted tooth through positioning holes of the same size. The specific position of the impacted tooth in the oral cavity can be clearly identified by imaging through the positioning holes.
[0021] Furthermore, the diameter of the positioning hole corresponds to the outer diameter of the positioning post, which facilitates the insertion of the positioning post into the positioning hole and also facilitates the removal of the positioning post from the positioning hole. This avoids instability inside the positioning post due to its small size or inability to be inserted into the positioning hole due to its large size.
[0022] Furthermore, the depth of the positioning hole corresponds to the length of the positioning post, so that after the positioning post is inserted into the positioning hole, it will not cause discomfort to the patient's gums due to the positioning post protruding from the positioning hole.
[0023] Furthermore, several positioning holes are correspondingly set on the buccal and palatal plates, which facilitates the accurate determination of the specific location of the impacted tooth under CT irradiation through the positioning holes on the buccal and palatal plates, avoiding the influence of inconsistent positioning hole positions on the buccal and palatal plates on the determination of the impacted tooth location.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0030] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, system, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, products, or devices.
[0031] The present invention will now be described in further detail with reference to the accompanying drawings:
[0032] The purpose of this invention is to provide a support and positioning guide plate structure for extracting impacted teeth, so as to solve the technical problem of low accuracy in imaging and positioning of impacted teeth in the prior art.
[0033] See Figure 1 and Figure 2 This embodiment provides a support and positioning guide structure for extracting impacted teeth, which is worn in the patient's oral cavity to locate the impacted teeth under CT irradiation. The support and positioning guide structure includes a jaw pad body 1.
[0034] The jaw pad body 1 includes a buccal plate 2 located anterior to the dental arch and a palatal plate 3 located posterior to the dental arch; the ends of the buccal plate 2 and the palatal plate 3 are connected by a base plate 4; the base plate 4 abuts against the end of the dental arch; each surface of the buccal plate 2 and the palatal plate 3 is provided with a positioning structure, which positions the impacted teeth on the surfaces of the buccal plate 2 and the palatal plate 3 under CT irradiation, such as... Figure 3 As shown.
[0035] Specifically, the positioning structure consists of several positioning holes 5, which are distributed on the buccal lateral plate 2 and the palatal lateral plate 3, and are all inserted through the plates of the buccal lateral plate 2 and the palatal lateral plate 3. Positioning posts 6 are inserted into each of the positioning holes 5, such as... Figure 4 As shown, the various positioning holes 5 are all of equal size. The diameter of the positioning hole 5 corresponds to the outer diameter of the positioning post 6. The depth of the positioning hole 5 corresponds to the length of the positioning post 6. The various positioning holes 5 are positioned correspondingly on the buccal plate 2 and the palatal plate 3.
[0036] Specifically, the structure of the jaw pad body 1 corresponds to the structure of the oral dental arch, wherein the structure of the buccal plate 2 corresponds to the buccal structure of the oral dental arch, and the structure of the palatal plate 3 corresponds to the palatal structure of the oral dental arch.
[0037] The buccal plate 2 includes an integrally formed labial plate 21 and two sets of buccal rows 22, with the two sets of buccal rows 22 located on either side of the labial plate 21. The labial plate 21 corresponds to the labial position of the dental arch, and the two sets of buccal rows 22 correspond to the buccal position of the dental arch. The width of the base plate 4 corresponds to the width of the dental arch.
[0038] In this embodiment, the jaw pad body 1 is the core component of the overall design, and its shape and structure directly correspond to the patient's oral dental structure. This means that the jaw pad body 1 will closely fit the patient's tooth arrangement in terms of shape, size, and contour to ensure stable support and positioning during CT scans and surgery.
[0039] The buccal plate 2 is an important component of the occlusal pad body 1, and its design is specifically tailored to the buccal structure of the oral dentition. It includes an integrally formed labial plate 21 and two sets of buccal plates 22. This design allows the buccal plate 2 to more comprehensively cover and adapt to the buccal region of the oral dentition.
[0040] The labial plate 21 is located in the central part of the buccal plate 2, directly corresponding to the labial side (i.e., the side facing the lips) of the oral dental row. The shape and contour of the labial plate 21 will closely fit the patient's anterior tooth area to ensure clear visualization during CT scans.
[0041] Two sets of buccal rows 22 are provided on each side of the labial plate 21, corresponding to the buccal positions of the dental rows in the oral cavity (i.e., the two sides of the teeth). The design of the buccal plates 22 helps to further stabilize the buccal plates 2 and increase their imaging area in CT scans, thereby improving the accuracy of positioning.
[0042] The palatal lateral plate 3 is another key component of the occlusal pad body 1, and its design corresponds to the palatal structure of the oral dentition. The palatal lateral plate 3 is typically located behind the buccal lateral plate 2, closely adhering to the patient's hard palate region. Its main function is to provide additional support and stability to ensure the correct positioning and fixation of the occlusal pad body 1 within the oral cavity.
[0043] The base plate 4 is the foundation of the occlusal pad body 1, and its width corresponds to the width of the patient's dental arch. This design ensures that the occlusal pad body 1 can be stably placed in the patient's mouth and can adapt to different patients' oral cavity sizes and shapes. The base plate 4 not only provides support and stability for the entire occlusal pad body 1, but also ensures that the buccal side plate 2 and palatal side plate 3 can accurately correspond to the patient's dental arch structure.
[0044] The jaw pad body 1 is made of thermoplastic material.
[0045] In this embodiment, the thermoplastic material has the property of softening and reshaping upon heating, allowing for precise customization and adjustment of the jaw pad according to the patient's oral dental structure during manufacturing. This property also facilitates later maintenance and adjustments; if shape or size modifications are needed, it can be reshaped by heating. Thermoplastic materials typically possess good transparency and high strength, ensuring that the jaw pad maintains both aesthetics and sufficient support during wear. The transparency also helps doctors to more clearly observe the patient's oral condition during imaging examinations such as CT scans.
[0046] In this embodiment, the buccal plate 2 and the palatal plate 3 are provided with a number of positioning holes 5, which are respectively disposed through the plates of the buccal plate 2 and the palatal plate 3. The distribution and number of these positioning holes 5 are carefully designed according to the oral cavity structure and the possible location of impacted teeth. Positioning posts 6 are matched with the positioning holes 5 and are used to be inserted into the positioning holes to fix and mark specific positions.
[0047] This embodiment requires preparation before CT scanning:
[0048] Place the buccal plate 2 and palatal plate 3 in the patient's mouth, ensuring that the positioning holes 5 correspond to the possible locations of impacted teeth, with positioning posts 6 inserted into each positioning hole 5 as reference points for CT scans.
[0049] Under CT scan, the buccal plate 2 and palatal plate 3, along with their internal positioning posts 6 and any potentially impacted teeth, are scanned. Due to the radiopaque properties of the positioning post 2, it will be clearly visible on the CT image.
[0050] After the scan is completed, the doctor analyzes the specific location of the impacted tooth using the CT images. Due to the imaging of the positioning post 6, the positioning holes 5 covered or adjacent to the impacted tooth can be clearly seen. Through comparison and analysis, the exact location, size, shape, and relationship with surrounding tissues of the impacted tooth are determined.
[0051] Based on the location information on CT images, doctors can develop precise surgical plans.
[0052] During the procedure, the positioning post 6 in the positioning hole 5 corresponding to the impacted tooth is first removed. Then, the soft tissue surface is marked through the positioning hole, and the impacted tooth is located and removed based on the positioning information.
[0053] The positioning jaw pad structure provided in this embodiment improves the accuracy and success rate of the surgery, and reduces patient pain and surgical risks.
[0054] In summary, this embodiment provides a support and positioning guide structure for extracting impacted teeth. The ends of the buccal and palatal plates are connected to a base plate, which abuts against the top of the dentition, allowing the occlusal pad to effectively fit against the dental arch. Positioning structures are provided on the surfaces of both the buccal and palatal plates. Under CT irradiation, the impacted tooth can be positioned on the surfaces of the buccal and palatal plates. The positioning structures can determine the specific location of the impacted tooth, improving the accuracy of impacted tooth positioning.
[0055] This embodiment provides a support and positioning guide structure for extracting impacted teeth. It adopts a prefabricated and individualized trimming method. Compared with the process of intraoral scanning-cone beam CT imaging-data transmission to the processing center-personalized customization by the processing center-patient wearing surgery of digital guides, it simplifies to intraoral shaping-cone beam CT imaging-patient wearing surgery. This reduces material and time costs, makes the production cost low, and significantly reduces the production time. It is conducive to large-scale promotion and use, and improves the quality of medical care, especially the surgical quality of primary medical institutions and young doctors.
[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
