In biomedical metal materials, titanium and titanium bar with excellent comprehensive performance, become artificial joints (hip, knee, shoulder, ankle, elbow, wrist, knuckles, etc.), bone trauma products (nails, steel plates, screws, etc.) and orthopaedic spine internal fixation system, braces, tooth orthopaedic silk, dental implants, artificial heart valve, interventional cardiovascular stents and other medicinal plant products in the material of choice. At present, there is no better metal material than titanium alloy for clinical use. In developed countries and the world famous implant product suppliers are attaches great importance to the research and development of titanium alloy, launched a series of new medical titanium alloy material, including bionic bioactive titanium alloy material, surface treatment in the medical titanium alloy material has also done a lot of design and development of proprietary, giving medical titanium alloy material better biological activity to meet the body's physiological needs, so as to achieve the purpose of make the patients recover at an early date.

For example, cheekbone plastic surgery involves two concepts: one is a simple cheekbone chisel to reduce the outline of the cheekbone; The other is a three-dimensional osteotomy, which shrinks the cheekbones by shortening and moving the pieces. Zygomatic chisel surgery is generally suitable for patients with prominent anterolateral face. It often adopts an internal incision to separate and expose zygomatic bone under periosteum. Special instruments are used to chisel and thin the part of zygomatic bone that was designed to be removed before surgery, so as to reduce the external facial contour and improve the facial shape. Use titanium nail, titanium plate is fixed for zygomatic won't cause slippery, cause facial outline to lose form, and still can better achieve zygomatic model result! The great advantage of this kind of surgery is that it leaves no scars, no scars. The difficulty of three dimensional zygomatic osteotomy is greatly increased, which is suitable for the patients with zygomatic arch protrusion. Besides oral incision, often in the hidden part as auxiliary incision in the hairline, or monoculture scalp coronal incision, subperiosteal separation after the cheekbones, according to the computer three-dimensional modeling design needs to be cut the size of a specific bone block, using special materials such as titanium nail would separate bone block to reconnect and shape, so that it can maximize the change the facial contour and facial type, even make patients to achieve the effect of "reborn".
