Description

Technical Field

[0001] This application belongs to the field of oral medical aesthetics technology, specifically relating to a guide plate for accurately assisting in confirming the final position of the gingival papilla in the restoration of crowns. Background Technology

[0002] In existing technologies, the morphology of gingival papillae plays an important role in the aesthetics of oral soft tissues. In the field of oral cosmetic medicine, the atrophy of gingival papillae in the patient's mouth forms a visually visible "black triangle," which will cause a series of problems such as aesthetic defects, speech disorders, and food impaction in the patient's mouth, and may even harm the health of periodontal tissues.

[0003] In existing technologies, gingival papilla reconstruction is an effective means of solving the "black triangle" in the oral cavity. However, the various methods for treating missing or defective gingival papillae are not very mature. Reconstructing interdental papillae in the aesthetic area is the most difficult and challenging periodontal treatment. Many factors affect the shape of the gingival papillae, including the distance between the contact point and the alveolar ridge crest, interroot distance, interroot separation angle, interdental distance, interproximal space morphology, crown shape, and gingival biotype. In current interdental papilla reconstruction surgery, it usually relies solely on oral imaging and the surgeon's experience. Due to individual patient differences, the surgical precision is low, and the optimal position for gingival papilla reconstruction cannot be determined by the maxillary bone position. Patient experience varies greatly. Therefore, improvements are urgently needed. Utility Model Content

[0004] This application addresses the technical problem in existing technologies where, during the treatment of missing or defective gingival papillae, numerous factors such as the patient's oral cavity root spacing, root separation angle, interdental spacing, interproximal space morphology, crown shape, and gingival biotype influence the surgical procedure. Relying solely on oral imaging and the surgeon's experience makes it impossible to determine the optimal location for gingival papilla reconstruction, thus reducing the patient's surgical experience, prolonging the operation time, and negatively impacting postoperative recovery. The application proposes a guide plate to precisely assist in confirming the final location of the gingival papilla in the restoration crown.

[0005] This application adopts the following scheme: a guide plate for accurately assisting in confirming the final position of the gingival papilla in the restoration of a crown, comprising a support guide plate body matched and disposed on the patient's maxilla, a fixing component disposed on the support guide plate body, a jawbone positioning component disposed on the support guide plate body, and a gingival papilla auxiliary reconstruction component disposed on the support guide plate body. When the support guide plate body is matched and disposed on the patient's maxilla, the periphery of the jawbone positioning component fits against the patient's maxilla, and the gingival papilla auxiliary reconstruction component coincides with the patient's target gingival papilla reconstruction area.

[0006] In one embodiment, the fixing component includes a fixing slot disposed on the main body of the support guide plate near the patient's maxillary alveolar bone, and a reinforcing rod disposed on the main body of the support guide plate and connected to the fixing slot. The positioning tooth on the patient's maxillary alveolar bone can be matched and extended into the fixing slot so that the main body of the support guide plate is matched and disposed on the patient's maxillary alveolar bone.

[0007] In one embodiment, an observation window is provided on the side of the support guide plate body away from the patient's upper alveolar bone. When the support guide plate body is fitted onto the patient's upper alveolar bone, the observation window is used to observe the degree of fit between the support guide plate body and the patient's upper alveolar bone.

[0008] In one embodiment, the fixing grooves are respectively located at both ends of the support guide plate body and are staggered, and the reinforcing rod is located between the two fixing grooves.

[0009] In one embodiment, the jawbone positioning assembly includes a positioning rod disposed between the two fixing slots. The positioning rod includes connecting portions respectively disposed on the two fixing slots and an arc-shaped portion disposed between the two connecting portions. The arc-shaped portion fits against the patient's maxilla.

[0010] In one embodiment, the arcuate portion is arcuate in the direction away from the patient's maxilla. When the main body of the support guide plate is matched and disposed on the patient's upper alveolar bone, the arcuate portion can fit against the patient's maxilla and is located above the patient's target gingival papilla reconstruction area.

[0011] In one embodiment, the gingival papilla-assisted reconstruction component is located below the positioning rod, and its two ends are respectively connected to the fixing groove.

[0012] In one embodiment, the support guide plate body, the fixation component, the jawbone positioning component, and the gingival papilla auxiliary reconstruction component are integrally formed.

[0013] Compared with the prior art, this application has the following beneficial effects:

[0014] This application provides a guide plate for accurately assisting in confirming the final position of the gingival papilla in the restoration of a crown. It includes a support guide plate body, a fixation component disposed on the support guide plate body, a jawbone positioning component disposed on the support guide plate body, and a gingival papilla auxiliary reconstruction component disposed on the support guide plate body. The support guide plate body is fabricated by combining oral imaging technology with 3D printing technology. By matching and setting the support guide plate body on the patient's maxillary alveolar bone, the target gingival papilla reconstruction area on the patient's maxillary alveolar bone can be accurately indicated, effectively improving the precision of the gingival papilla reconstruction surgery, confirming the optimal position for gingival papilla reconstruction, avoiding the influence of the surgeon's experience and individual differences on surgical quality, improving the patient's surgical experience, and having the advantage of being easy to promote and implement.

[0021] Combination Figure 1-6 The content shown further illustrates the technical solution provided in this application: a guide plate for accurately assisting in confirming the final position of the gingival papilla in the restoration of a crown, comprising a support guide plate body 1 matched and disposed on the patient's upper alveolar bone, a fixing component 2 disposed on the support guide plate body 1, a jawbone positioning component 3 disposed on the support guide plate body 1, and a gingival papilla auxiliary reconstruction component 4 disposed on the support guide plate body 1. When the support guide plate body 1 is matched and disposed on the patient's upper alveolar bone, the periphery of the jawbone positioning component 3 fits against the patient's maxilla, and the gingival papilla auxiliary reconstruction component 4 coincides with the patient's target gingival papilla reconstruction area.

[0022] This application provides a guide plate for accurately assisting in confirming the final position of the gingival papilla in the restoration of a crown. It includes a support guide plate body, a fixation component disposed on the support guide plate body, a jawbone positioning component disposed on the support guide plate body, and a gingival papilla auxiliary reconstruction component disposed on the support guide plate body. The support guide plate body is fabricated by combining oral imaging technology with 3D printing technology. By matching and setting the support guide plate body on the patient's maxillary alveolar bone, the target gingival papilla reconstruction area on the patient's maxillary alveolar bone can be accurately indicated, effectively improving the precision of the gingival papilla reconstruction surgery, confirming the optimal position for gingival papilla reconstruction, avoiding the influence of the surgeon's experience and individual differences on surgical quality, improving the patient's surgical experience, and having the advantage of being easy to promote and implement.

[0023] In this embodiment, the fixing component 2 includes a fixing groove 20 on the side of the support guide plate body 1 near the patient's upper alveolar bone, and a reinforcing rod 21 on the support guide plate body 1 and connected to the fixing groove 20. The positioning tooth on the patient's upper alveolar bone can be matched and extended into the fixing groove 20 so that the support guide plate body 1 is matched and disposed on the patient's upper alveolar bone.

[0024] In actual implementation, the design includes a support guide plate body that matches and is fixed to the patient's upper alveolar bone, as well as fixation components, jawbone positioning components, and gingival papilla auxiliary reconstruction components.

[0025] Specifically, when the main body of the support guide plate is matched and fixed to the patient's maxilla, the jawbone positioning component can fit closely with the patient's maxilla to ensure accurate positioning. At the same time, the gingival papilla auxiliary reconstruction component is precisely aligned with the gingival papilla area that needs to be reconstructed, helping to achieve precise reconstruction. The fixation component, through its fixation slot and reinforcing rod set on the main body of the support guide plate, ensures that the positioning tooth can be accurately inserted into the fixation slot. Thus, the main body of the support guide plate can be firmly fixed to the patient's maxilla, providing precise basic support for subsequent gingival papilla reconstruction. It has the advantage of being easy to promote and implement.

[0026] In this embodiment, an observation window 5 is provided on the side of the support guide plate body 1 away from the patient's upper alveolar bone. When the support guide plate body 1 is matched and placed on the patient's upper alveolar bone, the observation window 5 is used to observe the degree of fit between the support guide plate body 1 and the patient's upper alveolar bone.

[0027] In practice, an observation window is set on the side of the support guide away from the upper alveolar bone, which allows doctors to directly observe the fit between the guide and the patient's upper alveolar bone, further improving the accuracy and safety of the operation.

[0028] In this embodiment, the fixing grooves 20 are respectively located at both ends of the support guide plate body 1 and are staggered, and the reinforcing rod 21 is located between the two fixing grooves 20.

[0029] In this embodiment, the jawbone positioning component 3 includes a positioning rod 30 disposed between the two fixing slots 20. The positioning rod 30 includes a connecting part 31 disposed on the two fixing slots 20 respectively, and an arc-shaped part 32 disposed between the two connecting parts 31. The arc-shaped part 32 fits against the patient's maxilla.

[0030] In actual implementation, by setting staggered fixing grooves 20 at both ends of the main body 1 of the support guide plate and setting a reinforcing rod 21 between the two fixing grooves 20, the overall structural stability of the support guide plate is effectively enhanced. At the same time, in conjunction with the jawbone positioning component 3 set between the fixing grooves 20, including the connecting part 31 connected to the fixing groove 20 and the arc-shaped part 32 that fits closely with the maxilla, it can accurately align with the patient's maxilla position, providing stable support and positioning effect, ensuring the accuracy and comfort of the treatment process, and has the advantage of being easy to promote and implement.

[0031] In this embodiment, the arc-shaped part 32 is arc-shaped in the direction away from the patient's maxilla. When the support guide plate body 1 is matched and placed on the patient's upper alveolar bone, the arc-shaped part 32 can fit with the patient's maxilla and is located above the patient's target gingival papilla reconstruction area.

[0032] In this embodiment, the gingival papilla auxiliary reconstruction component 4 is located below the positioning rod 30, and both ends are connected to the fixing groove 20 respectively.

[0033] In this embodiment, the main body 1 of the support guide plate, the fixation component 2, the jawbone positioning component 3, and the gingival papilla auxiliary reconstruction component 4 are integrally formed.

[0034] In actual implementation, this application scans the patient's oral cavity structure using an oral imaging system to obtain the patient's oral cavity model data. Based on the patient's oral cavity model data, the main body 1 of the support guide plate, the fixation component 2, the jawbone positioning component 3, and the gingival papilla auxiliary reconstruction component 4 are modeled and then printed using a 3D printer. This effectively improves the accuracy of the main body of the support guide plate, making it easier to install on the patient's upper alveolar bone.

[0035] This application provides a guide plate for accurately assisting in confirming the final position of the gingival papilla in the restoration of a crown. It includes a support guide plate body, a fixation component disposed on the support guide plate body, a jawbone positioning component disposed on the support guide plate body, and a gingival papilla auxiliary reconstruction component disposed on the support guide plate body. The support guide plate body is fabricated by combining oral imaging technology with 3D printing technology. By matching and setting the support guide plate body on the patient's maxillary alveolar bone, the target gingival papilla reconstruction area on the patient's maxillary alveolar bone can be accurately indicated, effectively improving the precision of the gingival papilla reconstruction surgery, confirming the optimal position for gingival papilla reconstruction, avoiding the influence of the surgeon's experience and individual differences on surgical quality, improving the patient's surgical experience, and having the advantage of being easy to promote and implement.
