Biology Medical titanium material It is an important branch of material science. It is a new carrier material with high technology content and high economic value that is used to diagnose, treat or replace human tissues and organs or enhance their functions. It is also a new developing field of material science and technology. Biology Medical titanium rod Materials will make greater contributions to exploring the mysteries of human life and ensuring human health and longevity.

Among biomedical metal materials, titanium and titanium alloys have become artificial joints (hip, knee, shoulder, ankle, elbow, wrist, finger joints, etc.), bone trauma products (intramedullary nails, steel plates, screws, etc.), spinal orthopedic internal fixation systems, dental implants, dental brackets, dental orthopedic wires, artificial heart valves Materials for interventional cardiovascular stents and other medical implant products. At present, there is no better metal material than titanium alloy for clinical use. Developed countries and world famous internal implant product suppliers attach great importance to the research and development of titanium alloy, and have launched a series of new medical titanium alloy materials, including bioactive titanium alloy bionic materials. They have also done a lot of patented design and development in the surface treatment of medical titanium alloy materials, To endow medical titanium alloy materials with better biological activity to meet the physiological needs of the human body, so as to achieve the goal of early recovery of patients.

For example, plastic surgery of cheekbones mainly includes two concepts: one is simple chiseling of cheekbones to reduce the external contour of cheekbones; The other is three-dimensional osteotomy, which reduces the zygomatic bone by shortening and moving the bone block. Chiseling of cheekbones is generally suitable for patients with anterolateral facial protrusion. An intraoral incision is often used to separate and expose cheekbones under the periosteum. Special instruments are used to chisel away and thin the cheekbones designed to be removed before the operation, so as to reduce the external contour of the face and improve the face shape. The purpose of using titanium nails and titanium plates to fix the cheekbones is to prevent them from sliding, resulting in facial contour loss, and to better achieve the effect of cheekbones shaping! The big advantage of this operation is that there is no scar left after the operation. The difficulty of three-dimensional zygomatic osteotomy is greatly increased, which is suitable for patients with prominent zygomatic arch. In addition to the intraoral incision, it is usually necessary to make an auxiliary incision in the hidden part of the hairline, or a single coronal incision in the scalp. After the entire zygomatic bone is exposed through subperiosteal separation, the specific size of bone block is cut off according to the needs of three-dimensional computer simulation design, and then the separated bone block is reconnected and shaped with titanium nails and other special materials, In this way, Z can greatly change the entire facial contour and shape, and even make the patient achieve the effect of "reborn".
