Description

Technical Field

[0001] The utility model relates to the technical field of alveolar bone repair, in particular to a bracket used for alveolar bone repair. Background Art

[0002] The alveolar bone is also called the alveolar process, which is the protrusion of the jawbone surrounding the root of the tooth; the socket that accommodates the teeth is called the alveolar socket, the alveolar bone between the two teeth is called the alveolar interval, and the alveolar bone between the roots of multiple teeth is called the inter-root bone septum; the alveolar bone is the part where the roots of the teeth are embedded at the lower edge of the maxilla and the upper edge of the mandible; the alveolar process of the maxilla and mandible, the intrinsic alveolar bone is close to the inner wall of the tooth root and the periodontal membrane, and is a layer of bone compact with sieve holes and attached with periodontal membrane fibers; the alveolar bone is the most changeable part of the whole body's skeletal system, and its changes can reflect the remodeling process of bone tissue; it grows with the growth and eruption of teeth, and develops well due to physiological functional stimulation; after the loss of teeth, the normal functional stimulation is lost, and disuse atrophy may occur. Excessive stimulation can also cause traumatic absorption.

[0003] As the human body ages and teeth fall out, the alveolar bone often deforms and shrinks. At this time, when the alveolar bone is deformed or shrinks, it is impossible to directly implant teeth on the original alveolar bone, because in this case, the implant will cause secondary damage to the originally atrophied alveolar bone and cause the implant matrix to fall off or collapse. Therefore, when the alveolar bone shrinks, the alveolar bone needs to be reconstructed and thickened to meet the conditions for implantation before dental implantation can be performed;

[0004] In the prior art, when performing alveolar bone repair, screws and metal plates are usually used to fix cells and biomaterials on the alveolar bone. However, since there are usually gaps when the metal plates are fixed by screws, there may be a risk of infection. In severe cases, a second operation is required, causing secondary damage to the patient. Utility Model Content

[0008] Preferably, the bonding layer is further provided with a second annular sealing area at the periphery of the first annular sealing area close to the edge of the bracket plate body, and the screw is located on the inner side of the second annular sealing area.
