Defective mandibular fracture reconstruction titanium plate with auxiliary bone grafting function

Abstract

The invention discloses a defective mandibular fracture reconstruction titanium plate with an auxiliary bone grafting function. The defective mandibular fracture reconstruction titanium plate comprises a bridging part placed at the lower edge of the mandible and a support part placed at the lip and cheek side, wherein the bridging part comprises a main bridge body with the radian matched with that of the lower edge of the mandible and a main bone grafting bed; the support part comprises an auxiliary bridge body with the radian matched with that of the lip and cheek and an auxiliary bone grafting bed; the main bone grafting bed is arranged at the tongue side position of the main bridge body, the auxiliary bridge body is arranged in the middle of the auxiliary bone grafting bed, the auxiliary bone grafting bed is in moving connection with the main bridge body and the main bone grafting bed, and the main bone grafting bed and the auxiliary bone grafting bed are of titanium mesh structures. For the defective mandibular fracture reconstruction titanium plate with the auxiliary bone grafting function, the surgical operation is simplified, the surgical time is reduced, and the financial burden of patients is alleviated. Through the titanium-mesh bone grafting beds, the defect range is marked, meanwhile, the resetting of a fracture block is guided, the bending of the reconstruction plate during the surgery is avoided, the surgical time is reduced, the reconstruction plate and the mandible are in good lamination, and thus the fracture block displacement due to no laminating is avoided. The operation is simple, and the popularization is easy.

Description

technical field [0001] The invention relates to an auxiliary device for the reduction of mandibular fractures, in particular to a titanium plate for reconstruction of defective mandibular fractures with auxiliary bone grafting function. Background technique [0002] At present, my country is in a special historical period in which the economic and social development is steadily accelerating. With the popularization of transportation and the obvious acceleration of people's life rhythm, the number of patients with maxillofacial trauma and jaw fracture is also increasing year by year. The mandible is located in the prominent part of the maxillofacial region, and it is the only movable bone in the human head and face. Mandibular fractures often cause a series of symptoms including malocclusion, restricted mouth opening, and damage to the inferior alveolar nerve. [0003] With the development of science and technology, high-energy injury factors such as car accidents and explos...

Problems solved by technology

And stability is the most important thing for bone grafting: once the stability is not good, the residual bone is easy to move, causing infection, and eventually leading to the failure of bone grafting surgery

At present, all reconstruction plates do not have the function of assisting bone grafting. Cancellous bone or artificial replacement bone can only be placed on the surface of the soft tissue bone grafting bed, which has poor stability and a relatively high risk of infection.

[0007] At present, the commercialized reconstruction plate is used clinically. It is difficult to bend during the operation, and it is not easy to fit the jaw completely. This not only affects the operation efficiency, but also easily leads to the displacement of the fracture block, causing unnecessary surgical complications.
