Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a periodontal tissue auxiliary splint. Background Art

[0002] Periodontal disease refers to diseases that occur in the tooth-supporting tissues, including gingival disease that only affects the gingival tissue and periodontitis that affects the deeper periodontal tissues (periodontal ligament, alveolar bone, and cementum). Periodontal disease is a chronic inflammatory disease that recurs and progresses gradually. Clinically, the main symptoms are alveolar bone absorption and loose teeth, which gradually cause occlusal trauma and tooth displacement, and ultimately lead to tooth loss. The remaining teeth have poor supporting capacity and are difficult to repair and treat. The early symptoms of periodontal disease are not easily taken seriously, resulting in long-term chronic infection of the periodontal tissues and repeated inflammation, which not only damages the function of the oral chewing system but also seriously affects health.

[0003] Up to now, the treatment methods widely used in clinical practice are mostly embodied in the temporary bonding of ligature wires and composite resins to the teeth to form splints; or the use of fiber bands and composite resins to form splints; all of the above methods are made by bonding strips of resin to the lingual side of the teeth, while ligature wires and composite resin bonded splints can only be used temporarily; splints bonded with fiber bands and composite resins are prone to discoloration, plaque accumulation, resin peeling and secondary caries, and are mostly used in the medium and short term. Utility Model Content

[0004] Based on the problems mentioned in the above background technology, the utility model provides a periodontal tissue auxiliary splint.

[0005] The technical solution adopted by the utility model is as follows: a periodontal tissue auxiliary splint, including a splint body, which is arc-shaped, with one side that contacts the teeth as a bonding surface and the other side as a lingual side; the splint body includes at least two wing-shaped retainers, which are connected to each other by a connector to form an integral body, and the bonding surfaces of the wing-shaped retainers form a recessed portion on the lingual side.

[0006] Furthermore, the connector is convex toward the bonding surface in a conical shape.

[0007] Furthermore, the bottom end of the wing-shaped retainer is arc-shaped for matching with gums.

[0008] Furthermore, the thickness of the splint body is 0.7-1.0 mm.

[0009] Furthermore, the splint body is made of polyetheretherketone.

[0010] Furthermore, the bonding surface of the splint body has a uniform rough layer formed by sandblasting.

[0011] Furthermore, the top end of the wing-shaped retainer is lower than the incisal edge of the tooth.

[0012] Beneficial effects of the utility model:

[0013] The splint body is formed from a continuous series of wing-shaped retainers connected to a single piece. The specific number of wing-shaped retainers depends on the number of affected teeth and their adjacent teeth. They are used to assist in the fixation of the affected teeth, securing the loose teeth to another solid, healthy tooth, forming a new chewing unit and improving the patient's chewing function. They also disperse jaw forces, reduce the load on the periodontal tissue, and allow the affected teeth to rest physiologically, thus facilitating the recovery and healing of periodontal diseased tissue.

[0014] Since the bonding surface of the wing-shaped retainer forms a recessed portion on the lingual side, the wrapping of a single tooth is improved, ensuring that the wing-shaped retainer is adapted to the curvature of the incisor tooth surface and the connection is stable.

[0015] Compared to existing techniques that use strips, bands, composite resins, or fiber band composite resins bonded to the lingual side of a patient's periodontally affected teeth, these strip-shaped ligatures fail to conform the bonding surface to the tooth shape and are unable to minimize periodontal trauma during subgingival scaling or periodontal surgery. This application utilizes independent wing-shaped retainers that conform to the incisor tooth surface, integrally formed into a splint body that conforms to the patient's incisor tooth surface structure while minimizing periodontal trauma during thick strip scaling.

[0020] Adhesive surface 1, lingual side surface 2, wing-shaped retainer 3, connector 4, recessed portion 5. DETAILED DESCRIPTION

[0021] like Figures 1 and 2 As shown, a periodontal tissue auxiliary splint includes a splint body, which is in an arc shape, with one side that contacts the teeth as a bonding surface 1 and the other side as a lingual side 2; the splint body includes at least two wing-shaped retainers 3, and the two wing-shaped retainers 3 are connected to form an integral body through a connector 4, and the bonding surface 1 of the wing-shaped retainer 3 forms a recessed portion 5 toward the lingual side 2.

[0022] Using this technical solution, the splint body is integrally formed from a continuous series of wing-shaped retainers 3 connected by a connector 4. The specific number of wing-shaped retainers 3 depends on the number of affected teeth and their adjacent teeth. They are used to provide auxiliary fixation for the affected teeth, securing the loose teeth to other, secure, healthy teeth, forming a new masticatory unit and improving the patient's chewing function. They also disperse jaw forces, reduce the load on the periodontal tissue, and allow the affected teeth to rest physiologically, thereby facilitating the recovery and healing of periodontal diseased tissue.

[0023] Since the bonding surface 1 of the wing-shaped retainer 3 forms a recessed portion 5 toward the lingual side 2, the wrapping of a single tooth is improved, ensuring that the wing-shaped retainer 3 is adapted to the curvature of the incisor tooth surface and the connection is stable.

[0024] Compared to existing techniques that use strips, bands, composite resins, or fiber band composite resins bonded to the lingual side of a patient's periodontally affected teeth, these strip-shaped ligatures fail to conform the bonding surface 1 to the tooth's morphology and are unable to minimize periodontal trauma during subgingival scaling or periodontal surgery. The present invention utilizes independent wing-shaped retainers 3 that conform to the incisor tooth surface, integrally formed into a splint body that conforms to the patient's incisor tooth surface structure and reduces periodontal trauma during thick strip scaling.

[0025] As a preferred embodiment, the connector 4 is tapered and protrudes toward the bonding surface 1. The configuration of the connector 4 matches the adjacent gaps between teeth, facilitating cleaning and maintenance, and reducing accumulation of food residues and bacterial plaque.

[0026] As a preferred solution, the bottom end of the wing-shaped retainer 3 is an arc shape for matching the gums, which facilitates fitting with the affected tooth, improves support stability, and effectively disperses the bite force with a close fit, reducing the burden on the affected tooth.

[0027] As a preferred solution, the thickness of the splint body is 0.7-1.0 mm. The thickness of the splints in the prior art after bonding is 1.5-3.0 mm, which causes obvious discomfort to the patient. However, the present invention not only adapts to the shape of the affected tooth as a whole, but also further reduces the thickness of the splint body, thereby improving the patient's wearing comfort.

[0028] As a preferred solution, the splint body is made of polyetheretherketone (PEEK), which has good biocompatibility, high strength and toughness, and an elastic modulus closer to that of bone tissue, reducing the stress shielding effect and contributing to the health of surrounding bone tissue.

[0029] As a preferred solution, the bonding surface 1 of the splint body has a uniform rough layer formed by sandblasting. The provision of the rough layer greatly improves the bonding performance of the bonding surface 1.

[0030] As a preferred solution, the top of the wing-shaped retainer 3 is lower than the incisal edge of the tooth. The bottom of the wing-shaped retainer 3 is an arc-shaped to match the gums. At the same time, the top of the wing-shaped retainer 3 is limited in height and does not cover the incisal edge to avoid changing the occlusion of the patient's front teeth.

[0031] The above describes the present invention in detail. The description of the specific embodiments is intended only to facilitate understanding of the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
