Mandibular reconstruction scaffold

A mandible and bracket fixation technology, applied in the direction of bone implants, etc., can solve the problems of not taking into account the biomechanical state of the mandible, the lack of anti-infection ability of the all-heterogeneous prosthesis, and the thin oral mucosa, so as to reduce the fracture of the implant , Facilitate planting and reduce bone resorption

Problems solved by technology

However, regardless of the excellent physical and chemical properties of various materials, or the proficiency of 3D printing technology, it is impossible to avoid the fate of infection, exposure, and eventual removal of implants after mandibular reconstruction with all-heterogeneous materials.
The main reason is that the oral cavity is a bacterial environment (a second-class wound), the oral mucosa is thin, and the tight suture of the soft tissue cannot be per

Embodiment 1

[0040] This embodiment provides a mandibular reconstruction bracket, refer to Figure 1 to Figure 3 , the mandibular reconstruction scaffold is an irregular structure, including a first section 1 and a second section 2; wherein, the oblique angle between the first section 1 and the second section 2 is 30 to 60 degrees. Both sides of the first section 1 are respectively provided with at least one first nail hole 12, the first nail hole 12 penetrates the first section 1 and a second section 2, and is used for the mandibular reconstruction bracket. It is fixed on a first target; the first section 1 is provided with at least one second nail hole 13 for fixing the mandibular reconstruction bracket on the second target.

[0041] The first section 1 also includes a hollow design area, and the hollow design area is provided with at least one hollow hole 11, which is conducive to the attachment of the jaw ascending and descending muscle groups such as the mandibular hyoid bone and the ...

Abstract

The invention discloses a mandibular reconstruction scaffold. The mandibular reconstruction scaffold has an irregular structure and comprises a first cross section and a second cross section, whereinan oblique angle between the first cross section and the second cross section is 30 to 60 degrees; two sides of the first cross section are respectively provided with at least one first nail hole; each first nail hole penetrates through the first cross section and the second cross section and is used for fixing the mandibular reconstruction scaffold onto a first target; and at least one second nail hole is arranged on the first cross section and used for fixing the mandibular reconstruction scaffold onto a second target. The mandibular reconstruction scaffold provided by the invention can reconstruct a mandible in a manner of compound vascularized bone graft, and can effectively reduce occurrence of serious complications like infection, rejection and stress shielding caused by mandibular reconstruction with completely-heterogeneous materials.

Description

technical field [0001] The invention relates to the technical field of oral and maxillofacial repair and reconstruction, in particular to a mandibular reconstruction support. Background technique [0002] Vascularized autologous bone grafting: At present, this method is widely used for mandibular reconstruction, mainly including fibula and ilium. However, the vertical height of the fibula is insufficient, and it is difficult to complete the implantation at the same time, and the horizontal length of the ilium is insufficient to be used for a large-scale mandibular defect across the midline. Some teams have used fibula double stacking, Onlay bone grafting, or distraction osteogenesis to increase vertical bone volume, but these methods not only increase the trauma of the donor site, but also increase the difficulty of surgery and treatment cycle, increasing the pain of the patient. [0003] Reconstruction of the mandible with all-heterogeneous materials: With the maturity of ...
