Description

Technical Field

[0001] This application belongs to the field of oral medical device technology, specifically relating to a permanent periodontal splint made of zirconia all-ceramic material. Background Technology

[0002] In existing technologies, periodontal splints play a crucial role in the treatment of periodontal disease. They can hold loose teeth together, distribute occlusal forces, enhance chewing function, and improve patients' chewing efficiency and quality of life. However, the materials used in current periodontal splints on the market have some shortcomings.

[0003] While metal splints possess sufficient strength and toughness to effectively stabilize loose teeth, they suffer from poor aesthetics, potentially affecting the patient's smile and causing psychological distress. Resin splints, such as those made of PEEK, offer better aesthetics and blend well with tooth color, but their strength is relatively low, making them prone to breakage or deformation under significant biting forces. Furthermore, PEEK materials exhibit poor osteogenic properties and unsatisfactory interaction with bone tissue.

[0004] Therefore, improvements are urgently needed to comprehensively enhance the mechanical properties, biocompatibility, and aesthetics of periodontal splints, thereby improving the patient experience and restorative outcomes. Utility Model Content

[0005] In order to address the technical problems in the prior art where periodontal splints are mostly made of metal or resin, the former has poor aesthetics and the latter has low connection strength with the affected tooth, short service life, poor patient experience, and poor tooth restoration effect, this application proposes a permanent periodontal splint made of zirconia all-ceramic material.

[0006] This application adopts the following scheme: a permanent periodontal splint made of zirconia all-ceramic material, including a splint body respectively disposed on the buccal and lingual sides of the affected tooth, the splint body including a clamping part disposed on the vertical surface of the affected tooth, and a connecting part disposed on both ends of the clamping part, the splint body including a decorative layer, a support layer and a connecting layer stacked sequentially from the outside to the inside, the support layer being made of zirconia.

[0007] In some feasible embodiments, the thickness of the decorative layer is defined as A, the thickness of the support layer as B, and the thickness of the connecting layer as C;

[0008] A, B, and C satisfy the following relationships: B > A, B > C, A > C, 0.5mm ≤ B ≤ 1.2mm.

[0009] In some feasible embodiments, the decorative layer is made of ceramic glaze, and the connecting layer is made of silane coupling agent.

[0010] In some feasible embodiments, the bonding layer is selected as a sandblasted layer, the porosity of the bonding layer is 1%-5%, and the surface roughness Ra of the bonding layer is 0.95μm-1.05μm.

[0011] In some feasible embodiments, a first clearance gap is provided between the splint body and the gingiva of the affected tooth, and a second clearance gap is provided between the splint body and the top of the affected tooth.

[0012] In some feasible embodiments, the height of the clamping plate body is defined as H, the height of the first clearance gap is h1, and the height of the second clearance gap is h2.

[0013] H, h1, and h2 satisfy the following relationships: h1≤h2, 1 / 3≤H / (H+h1+h2)≤3 / 4.

[0014] In some feasible embodiments, two splint bodies respectively located on the buccal and lingual sides of the affected tooth are integrally formed, the two splint bodies are arranged in a ring, and the two splint bodies together form a clamping hole, and one or more consecutive affected teeth are matched and placed in the clamping hole.

[0015] Compared with the prior art, this application has the following beneficial effects:

[0016] This application provides a permanent periodontal splint made of zirconia all-ceramic material, comprising a splint body respectively positioned on the buccal and lingual sides of the affected tooth. The splint body includes a clamping portion on the vertical surface of the affected tooth and connecting portions at both ends of the clamping portion. The splint body includes a decorative layer, a support layer, and a connecting layer stacked sequentially from the outside to the inside. The support layer is made of zirconia.

The decorative layer can be made of a material similar in color to teeth, further enhancing aesthetics. Furthermore, the multi-layered structure of this splint ensures clear function and synergistic action of each layer, effectively improving the stability and lifespan of the splint.

[0024] Combination Figure 1-7 The content shown further illustrates the technical solution provided in this application: a zirconia all-ceramic permanent periodontal splint, comprising a splint body 1 respectively disposed on the buccal and lingual sides of the affected tooth, the splint body 1 including a clamping part 10 disposed on the vertical surface of the affected tooth, and connecting parts 11 disposed at both ends of the clamping part 10, the splint body 1 having a layered structure, the splint body 1 including a decorative layer 12, a support layer 13, and a connecting layer 14 stacked sequentially from the outside to the inside, the support layer 13 being made of zirconia.

[0025] In practice, the periodontal splint provided in this application can be designed directly using CAD and then manufactured using CAM-cut zirconia. While ensuring its original mechanical properties, the aesthetics and biocompatibility of the splint are improved, thus providing the wearer with a better experience and enhancing the comfort of use for a more perfect restorative effect.

[0026] This application provides a permanent periodontal splint made of zirconia all-ceramic material, comprising a splint body respectively positioned on the buccal and lingual sides of the affected tooth. The splint body includes a clamping portion on the vertical surface of the affected tooth and connecting portions at both ends of the clamping portion. The splint body includes a decorative layer, a support layer, and a connecting layer stacked sequentially from the outside to the inside. The support layer is made of zirconia. By using zirconia as the support layer material, it combines high strength with good biocompatibility, ensuring effective fixation of loose teeth while avoiding the aesthetic problems associated with metal splints. The decorative layer can be made of a material similar in color to teeth, further enhancing aesthetics. Furthermore, the multi-layered structure of this splint ensures clear function and synergistic action of each layer, effectively improving the stability and lifespan of the splint. It has the advantages of simple structure and manufacturing process, meeting the needs of periodontal disease treatment while better considering the aesthetic needs and user experience of patients, and is easy to promote and implement.

[0027] In this embodiment, the thickness of the decorative layer 12 is defined as A, the thickness of the support layer 13 is defined as B, and the thickness of the connecting layer 14 is defined as C.

[0028] The following relationships are satisfied by A, B, and C: B > A, B > C, A > C, and 0.5mm ≤ B ≤ 1.2mm.

[0029] In actual implementation, by designing the thickness of the support layer, decorative layer, and connecting layer, the mechanical strength of the periodontal splint can be increased, avoiding breakage if the splint is too thin and increased foreign body sensation and reduced user experience if it is too thick.

[0030] In this embodiment, the decorative layer 12 is made of ceramic glaze, and the connecting layer 14 is made of silane coupling agent.

[0031] In practice, by using ceramic glaze as a decorative layer, not only can the periodontal splint be made more realistic and closer in appearance to real teeth, but it can also reduce plaque buildup.

[0032] In actual implementation, by using silane coupling agent as the connecting layer, the specific surface area, surface micropores and surface roughening effect of the support layer can be significantly increased, achieving a good acid etching effect, thereby giving it good adhesion performance and improving the installation stability of the clamp body.

[0033] In this embodiment, the connecting layer 14 is a sandblasted layer, and the porosity of the connecting layer 14 is 1%-5%.

[0034] In actual implementation, a 50-micron silicon-containing alumina powder is sprayed onto one side of the support layer using a sandblasting machine. This alters the surface physical structure, creating micropores on the surface and increasing surface roughness, thereby improving the bonding effect.

[0035] In this embodiment, a first clearance gap 2 is provided between the splint body 1 and the gingiva of the affected tooth, and a second clearance gap 3 is provided between the splint body 1 and the top of the affected tooth.

[0036] In this embodiment, the height of the clamping plate body 1 is defined as H, the height of the first clearance gap 2 is defined as h1, and the height of the second clearance gap 3 is defined as h2.

[0037] The H, h1, and h2 satisfy the following relationships: h1≤h2, 1 / 3≤H / (H+h1+h2)≤3 / 4.

[0038] In actual implementation, by setting the first and second clearance gaps and designing the height of the splint body, patients can avoid interfering with their gums during biting, thus improving their user experience.

[0039] In this embodiment, the two splint bodies 1, which are respectively located on the buccal and lingual sides of the affected tooth, are integrally formed. The two splint bodies 1 are arranged in a ring and together form a clamping hole 4. One or more consecutive affected teeth are matched and placed in the clamping hole 4.

[0040] In actual implementation, by arranging the two main bodies 1 of the splint in a ring shape, they can be fastened to the surface of the affected tooth. They not only have adhesive retention force, but also a certain mechanical retention force, and the overall restoration effect of the affected tooth is also better.

[0041] This application provides a permanent periodontal splint made of zirconia all-ceramic material, comprising a splint body respectively positioned on the buccal and lingual sides of the affected tooth. The splint body includes a clamping portion on the vertical surface of the affected tooth and connecting portions at both ends of the clamping portion. The splint body includes a decorative layer, a support layer, and a connecting layer stacked sequentially from the outside to the inside. The support layer is made of zirconia. By using zirconia as the support layer material, it combines high strength with good biocompatibility, ensuring effective fixation of loose teeth while avoiding the aesthetic problems associated with metal splints. The decorative layer can be made of a material similar in color to teeth, further enhancing aesthetics. Furthermore, the multi-layered structure of this splint ensures clear function and synergistic action of each layer, effectively improving the stability and lifespan of the splint. It has the advantages of simple structure and manufacturing process, meeting the needs of periodontal disease treatment while better considering the aesthetic needs and user experience of patients, and is easy to promote and implement.

[0042] The above are merely embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
