Mandibular implant and method of making same

Abstract

The invention discloses a mandibular implant and a manufacturing method thereof, including the steps of designing and manufacturing the negative shape of the bracket, designing and making the outer shell, perfusing biological materials, heating to melt the negative shape of the bracket and the outer shell, sandblasting to remove wax, and dissolving with dilute hydrochloric acid. . The invention has the internal structure capable of imitating the natural bone of the human body, and manufactures a mandibular implant with a dense layer and a loose layer, which is similar to the internal structure and mechanical properties of the natural bone of the human body; during the process of filling the negative material of the bracket, the shell provides Give negative external stress to the scaffold, so that the negative structure of the scaffold is stable and not easy to collapse; by corroding the internal pores of the biomaterial scaffold, growth factors and bone cells are more likely to attach to the surface of the pores, and the amount of attachment is more, effectively improving the survival rate of bone Etc.

Description

technical field [0001] The invention relates to a mandibular implant and a manufacturing method thereof. Background technique [0002] The mandible is the largest in volume and area among the maxillofacial bones of the human body, and it is also the only movable bone in the face. As the main supporting structure of the facial shape, the mandible is complex in shape and has strong individual characteristics. At present, mandibular defect caused by trauma, tumor resection and deformity correction has become a common clinical disease. Mandibular defect will affect the patient's swallowing, language, chewing and other functions, and lead to facial deformity and reduce the quality of life. [0003] The main method of clinically repairing mandibular defects is to take bone implants from different parts of the patient's own body for graft repair, such as taking bone from the iliac crest, rib or fibula. This technology has been used clinically for many years and is relatively matur...

AI Technical Summary

Problems solved by technology

However, the disadvantages of this method are: the fabricated scaffold negative does not have the internal structure and mechanical properties of human natural bone; in the process of filling biomaterials, the internal microstructure is easy to collapse because the scaffold negative is not protected by external forces ;During the process of making the implant, the molding material of the negative type of the bracket is likely to remain inside and on the surface, causing adverse effects; growth factors and bone cells are not easy to attach to the surface of the mandibular implant, and the bone survival rate is low
