Abstract

The application provides a zirconia all-ceramic constant periodontal splint which comprises a splint main body which is respectively arranged on the buccal side and the lingual side of a patient's tooth, wherein the splint main body comprises a clamping part which is arranged on the elevation of the patient's tooth, and connecting parts which are arranged on two ends of the clamping part, the splint main body comprises a decorative layer, a supporting layer and a connecting layer which are sequentially overlapped from outside to inside, and the supporting layer is made of zirconia. By adopting zirconia as the material of the supporting layer, the composite material has high strength and good biocompatibility, not only ensures the effective fixation of loose teeth, but also avoids the problem that the metal splint affects the beauty. The decorative layer can be made of materials with similar colors to teeth, so that the attractiveness is further improved. In addition, the multilayer structure design of the splint ensures that each layer has definite functions and synergistic effect, and effectively improves the stability and the service life of the splint. The device has the advantages of simple structure and production process, attractive requirements and use experience of patients are considered while the requirements of periodontal disease treatment are met, and popularization and implementation are facilitated.

Description

Zirconia all-ceramic constant periodontal splint Technical Field The application belongs to the technical field of oral medical appliances, and particularly relates to a zirconia all-ceramic constant periodontal splint. Background In the prior art, the periodontal splint plays a vital role in periodontal disease treatment, and can fix loose teeth together, disperse resultant force of teeth, strengthen chewing function of the teeth and improve chewing efficiency and life quality of patients. However, the periodontal splint materials on the market currently have some disadvantages. In the prior art, although the metal splint has enough strength and toughness and can effectively fix loose teeth, the metal splint has poor appearance in the aspect of aesthetic property, and is easy to influence the beauty of smile of a patient, thereby bringing a certain psychological pressure to the patient. While the periodontal splint made of resin material such as PEEK material has good aesthetic property and can coordinate with the color of teeth, the intensity is relatively low, and the periodontal splint is easy to break or deform when bearing large biting force. In addition, PEEK materials have the defects of poor osteogenesis effect and unsatisfactory interaction with bone tissues. Therefore, in order to comprehensively improve the mechanical properties, biocompatibility and aesthetic properties of the periodontal splint, improvements are now urgently needed to improve the use experience and repair effect of patients. Disclosure of utility model The application provides a zirconia all-ceramic constant periodontal splint, which aims to solve the technical problems of the prior art that most of materials of the periodontal splint are metal or resin, the aesthetic property of the former is poor, the connection strength between the latter and the affected teeth is low, the service life is short, the use experience of patients is poor and the affected teeth repairing effect is poor. The application adopts the following scheme that the zirconia all-ceramic constant periodontal splint comprises a splint main body which is respectively arranged on the buccal side and the lingual side of a patient tooth, wherein the splint main body comprises a clamping part which is arranged on the patient tooth elevation and connecting parts which are arranged on two ends of the clamping part, the splint main body comprises a decorative layer, a supporting layer and a connecting layer which are sequentially overlapped from outside to inside, and the supporting layer is made of zirconia. In some possible embodiments, the thickness of the decorative layer is defined as a, the thickness of the support layer is defined as B, and the thickness of the connection layer is defined as C; A.
