Problems solved by technology

[0003] When the human body ages and the teeth fall off, the alveolar bone often deforms and atrophies. Dental implants, because in this case, dental implants will cause secondary damage to the originally atrophied alveolar bone and cause the matrix of the implant to fall off or collapse. Therefore, when the alveolar bone shrinks, it is necessary to repair the tooth The alveolar bone is reconstructed and the alveolar bone is thickened and corrected so that it meets the conditions for dental implants before dental implants can be performed. However, the existing alveolar bone repair technology often uses titanium mesh for fixed repair, and the titanium mesh is often fixed with screws. , and in this way, the removal of the titanium mesh requires a second operation, and the tapping and tightening of the screw will cause multiple injuries to the fragile alveolar bone, and the patient will cause secondary injuries. Therefore, there is a lack of one on the market. A method of alveolar bone repair that does not require repeated operations and does not cause damage to the original alveolar bone

Embodiment 1

[0048] like Figure 1-4 As shown, a capless positioner 1 of the present invention includes a columnar portion 103 and a pile head 105, and the columnar portion 103 and the pile head 105 are integrally made of a special material, which needs to be decomposable and can be used by the human body. The characteristics of absorption should also have the characteristics of hot melt and plasticity, and the material can be specifically selected from polylactic acid and its polymer materials.

[0049] like figure 1 or 3, the circumferential sidewall of the columnar portion 103 has protrusions in different directions, and adjacent protrusions protrude in different directions to form staggered layers, and scrape collection grooves 104 are formed between the staggered layers. The sump 104 can scrape and collect bone powder on the side wall of the bone hole.

[0050] The protrusion of the columnar part 103 above can be designed as a square, rectangular, U-shaped or concave-convex shape al...

Embodiment 2

[0055] like Figure 1-4 As shown, a capless positioner 1 of the present invention includes a columnar portion 103 and a pile head 105, and the columnar portion 103 and the pile head 105 are integrally made of a special material, which needs to be decomposable and can be used by the human body. The characteristics of absorption should also have the characteristics of hot melt and plasticity, and the material can be specifically selected from polylactic acid and its polymer materials.

[0056] like figure 1 or 3, the circumferential sidewall of the columnar portion 103 has protrusions in different directions, and adjacent protrusions protrude in different directions to form staggered layers, and scrape collection grooves 104 are formed between the staggered layers. The sump 104 can scrape and collect bone powder on the side wall of the bone hole.

[0057] like figure 1 Or as shown in 3, the pile head 105 is dovetail or V-shaped, and the pile head 105 is provided with a V-shap...

Embodiment 3

[0062] like Figure 2-9 As shown, a capped positioner 1 of the present invention includes a columnar part 103, a pile head 105 and a tail cap part 102; the columnar part 103, the pile head 105 and the tail cap part 102 are integrally made of special materials, The pile head 105 and the tail cap 102 are respectively connected to the front and rear ends of the columnar part 103. The special material needs to be decomposable and absorbed by the human body, and should also have the characteristics of heat melting and plasticity.

[0063] like Figure 5 As shown in or 9, there are protrusions in different directions on the circumferential side wall of the columnar portion 103, and adjacent protrusions protrude in different directions to form staggered layers, and scrape collection grooves 104 are formed between the staggered layers. The sump 104 can scrape and collect bone powder on the side wall of the bone hole; the protrusion can be designed as a square, a rectangle, a U shape,...

Abstract

The invention relates to a bracket structure for alveolar bone reconstruction, which belongs to the field of artificial restoration of alveolar bone, and is used to cover the buccal or lingual side of the maxillary surface of the alveolar bone where teeth are missing, including: L A font-shaped preformed bracket; a transverse valve part, which constitutes the transverse part of the preformed bracket, and can cover the lateral area of ​​the maxillary surface from the alveolar to the tooth root; the longitudinal base part, which constitutes the vertical part of the preformed bracket to the part, and connected with the transverse valve part to form an L shape; the longitudinal base part can cover the vertical area of ​​the maxillary surface from the alveolar to the root; the connecting part is used to connect the alveolar bone Locator; between the preformed bracket and the maxillary surface of the alveolar bone, a bone graft space for bone graft filling is formed; the bone graft material provides a supporting space with sufficient strength, and its deformation strength and tensile strength can be satisfied ; Its material is also absorbable material, and its transverse valve part can be opened and filled with bone graft material.

Description

technical field [0001] The invention relates to a bracket structure for reconstruction of alveolar bone, which belongs to the field of artificial repair of alveolar bone. Background technique [0002] The alveolar bone, also known as the alveolar process, is the protrusion of the jaw that surrounds the root of the tooth; the socket that accommodates the teeth is called the alveolar fossa, the alveolar bone between two teeth is called the alveolar interval, and the alveolar bone between the roots of multiple teeth is called The interroot bone septum; the alveolar bone is the part where the lower edge of the maxilla and the upper edge of the mandible are inlaid with the roots; the alveolar process of the upper and lower jaws, the proper alveolar bone is close to the inner wall of the root and periodontal ligament, and is a layer Cortical bone with sieve holes and attached periodontal ligament fibers; alveolar bone is the most variable part of the whole body skeletal system, an...
