Gr1 pure titanium plate for medical use (medical titanium plate for short) is the important material in the modern medical implant field, which plays an irreplaceable role in medical field such as orthopedics department and craniomaxillofacial surgery by its outstanding biocompatibility and mechanic properties.
The most prominent advantages of medical titanium plate is biocompatibility. Titanium surface can form a stable oxide layer with human tissue, which can prevent corrosion and metal ion release effectively and avoid rejection reaction. Clinical data shows that the infection rate is lower than 1% when the plate implanted, more lower than that of the stainless steel or other traditional materials. These properties enable the medical titanium plate to exist in human body stably for a long time and provide reliable support for bone healing.
In the aspect of mechanic properties, the elasticity modulus of the medical titanium plate is close to human bones. It can disperse the stress effectively and avoid stress-shielding effect. At the same time, the plate has excellent strength and toughness, and can withstand all kinds of mechanical load from the body in the daily activities. Taking the bone fracture plate as the example, its tensile strength can reach above 900MPa which can meet the clinic requirements completely.
Medical titanium plate applies in extensive fields. In the field of orthopedics, it is used for surgeries of fracture fixation and spinal fusion; in the field of craniomaxillofacial surgery, it is used for the surgeries of cranial bone repair and maxillofacial plastic surgery; in the field of dental implanting, it is used for the implant abutment. According to statistics, the annual usage amount of medical titanium plate is more than a million pieces. Its market size is more than 5 billion dollars.
With the development of 3D printing technology, customized titanium plate becomes a new trend. CT scanning and 3-dimensional image reconstruction can accurately make the titanium plate completely matched to patient anatomy, which can improve the accuracy and the effects of the surgeries. At present, titanium plate 3D printing has obtained good application effects in the field of the complicated fracture repair.
In short, medical titanium plate has become the important material in the modern medicine. Its performance improvement and application extension will continue to push the development of medical technology and bring better treatment effects for the patients. Due to its advantages of material properties, it has been applied widely in medical field and it is recognized as the special material in national regulations.
Explanation of special materials
According to national regulations to high-tech special materials, medical titanium plate is able to be recognized as the special material. Its production and sales need further declaration and approval. Because medical titanium plate has the special application value in medical surgeries and treatment, it is positioned as a special medical material.
