Biotechnology amount of mouth custom mandibular
Germany has recently accepted a special jaw transplant. This particular jaw computer design laboratory to nurture the patient back to "nurture", and then implanted in his face.
And cultivate the lower jaw of the patient design scientists at the University of Kiel, Germany. In the latest issue of "Lancet" magazine reported that the First, the patient's head CT scan, and then use computer software to design virtual jaw of an exact match with the patient face, and then according to this virtual jaw a model made of Teflon. Then, the scientists covered with a thin layer of titanium mesh model, the model removed, leaving a jaw shape of the titanium mesh shell. The scientists then injected to the shell in constitute the bone mineral hydroxyapatite, from a patient's own bone marrow with stem cells in the blood and a genetically engineered protein. The transgenic protein can induce stem cells in the blood and the formation of new bone.
Next, the artificial jaw also need to have a blood supply system. To this end, the doctor it implanted rich in blood vessels of patients with right shoulder blade at the location to differentiate connected with the muscle tissue and blood vessels. In the transplant, the doctor will mandibular blood vessels with the blood vessels of patients with brain connected together. Because the lower jaw is custom-made for patients, "the amount of mouth", so it is well matched to the patients face.
Currently, bone transplants are generally directly from other parts of the cut-off of the patient's body for some bones, and then transplanted to the affected area. This surgery can cause bone density loss and secondary infection, the recovery process is very slow. New technology is more secure, the pain caused to the patients is smaller, and better postoperative results.
