The world's population is nearly 6.5 billion,and according to incomplete statistics,there are close to 400 million disabled individuals,60 million with limb disabilities,and 2 billion with dental diseases.Currently,only 35 million people have implants made of biomaterials,and there are approximately 1.5 million joint replacements performed annually,which is far from the actual number of people in need of replacements.Therefore,the market demand for biomedical materials has great potential.As the preferred choice for biomedical metal materials,the demand for titanium rods and plates will also increase significantly.It is imperative for medical titanium rod manufacturers to intensify their research and development efforts in medical titanium alloy materials.

Biomedical titanium materials constitute an important branch of materials science.They are novel carrier materials with high technological content and economic value,intended for diagnosing,treating,or replacing human tissues and organs,or enhancing their functions.This represents a burgeoning field within materials science and technology.Biomedical titanium rods are making significant contributions to exploring the mysteries of human life and ensuring human health and longevity.

In biomedical metallic materials,titanium and titanium alloys have become the preferred materials for artificial joints(hip,knee,shoulder,ankle,elbow,wrist,finger joints,etc.),orthopedic trauma products(intramedullary nails,steel plates,screws,etc.),spinal orthopedic internal fixation systems,dental implants,dental prostheses,dental orthopedic wires,artificial heart valves,interventional cardiovascular stents,and other medical implant products,due to their excellent comprehensive performance.Currently,there is no better metal material than titanium alloys for clinical use.Developed countries and world-renowned suppliers of internal implants attach great importance to the research and development of titanium alloys,and have launched a series of new medical titanium alloy materials,including bioactive titanium alloy biomimetic materials.They have also made many patented designs and developments in the surface treatment of medical titanium alloy materials,endowing them with better bioactivity to meet the physiological needs of the human body,thereby achieving the goal of early recovery for patients.For example,zygomatic surgery mainly includes two concepts:one is simple zygomatic osteotomy to reduce the outer contour of the zygomatic bone;the other is three-dimensional osteotomy,which achieves zygomatic reduction through the shortening and movement of the bone block.Zygomatic osteotomy is generally suitable for patients with prominent facial anterior-lateral features,often using intraoral incisions to expose the zygomatic bone under the periosteum.Special instruments are applied to chisel and thin the part of the zygomatic bone that is intended to be removed according to preoperative design,thereby reducing the facial outer contour and improving the facial shape.The use of titanium screws and plates for fixation is to prevent the zygomatic bone from sliding and causing facial contour deformities,and also to better achieve the effect of zygomatic shaping!The biggest advantage of this surgery is that it leaves no scars after surgery,seamless and untraceable.The difficulty of three-dimensional zygomatic osteotomy surgery is greatly increased,and it is suitable for patients with prominent zygomatic arches.In addition to intraoral incisions,auxiliary incisions are usually made in concealed areas within the hairline,or a single intracranial coronal incision is made.After separating and exposing the entire zygomatic bone under the periosteum,a specific size of bone block is cut according to the needs of computer three-dimensional simulation design,and then the separated bone block is reconnected and shaped using special materials such as titanium screws.This can maximize the change of the entire facial contour and facial shape,even achieving the effect of"being born again"for patients.
