Core Applications of Medical Titanium Alloy Plates

Medical titanium alloy plates have become indispensable key materials in the medical field due to their outstanding biocompatibility, corrosion resistance, mechanical properties, and excellent formability. Their core applications primarily focus on human hard tissue replacement, repair, and the manufacturing of medical devices.

1. Orthopedic Field

As a core application scenario, medical titanium alloy plates are widely used in implant processing, covering various fields such as human bone defect repair, fracture fixation, and joint replacement, meeting the repair needs of multiple skeletal regions. For instance, core components of artificial joints like the hip, knee, and shoulder, as well as critical parts such as acetabular cups, femoral head bases, and tibial plateaus, are manufactured through processes including plate cutting, forging, and mechanical machining. These components possess mechanical properties close to human bone, effectively distributing joint stress and preventing bone resorption. Their excellent biocompatibility reduces rejection reactions, ensuring long-term stability of artificial joints with a service life of 15 to 20 years. Additionally, they can be used to produce various bone plates and bone clamps, such as tibial plates and femoral plates, which can be bent and shaped according to the actual bone contours to adapt to complex anatomical structures, providing stable support for fracture sites to promote healing. These plates also exhibit superior resistance to body fluid corrosion, allowing most materials to remain in the body long-term without requiring secondary surgery for removal. For bone defects caused by tumor resection or trauma, the plates can also be processed into customized bone repair prostheses and bone fillers, achieving skeletal structure reconstruction and functional recovery through precise fitting of the defect shape, particularly suitable for the treatment of large-area bone defects.

II. Dental Field

Medical titanium alloy plates are widely used in dental applications due to their excellent biocompatibility and outstanding tolerance to oral environments (such as saliva and acidic food). They can be processed into components like dental implant abutments and healing caps, which connect implants to crowns, ensuring effective tissue integration, reducing post-implantation inflammation, and significantly enhancing the stability and lifespan of dental implants. Additionally, they can be custom-made into mandibular repair frameworks and oral support plates to address jawbone defects and facial injury restoration needs. These products support oral soft tissues, help patients regain chewing function and facial aesthetics, and feature lightweight materials that do not interfere with normal oral activities. Furthermore, the plates serve as substrates for partial orthodontic brackets and appliances, meeting mechanical support requirements for orthodontic treatment with high strength and wear resistance while avoiding irritation to oral mucosa.

III. Cardiology Field
In the field of cardiovascular disease treatment, medical titanium alloy plates are primarily used to manufacture high-precision, high-reliability interventional and implantable devices, leveraging their resistance to blood corrosion, excellent biocompatibility, and stable mechanical strength. On one hand, they can be employed to produce core components such as valve frames and leaflet support structures for artificial heart valves. Their high strength ensures structural stability during the periodic contraction and relaxation of the heart muscle, while their resistance to blood corrosion prevents material degradation and avoids the generation of harmful substances. Additionally, their biocompatibility reduces the risk of thrombosis, making them suitable for the complex physiological environment within the heart. On the other hand, these plates serve as foundational materials for devices such as coronary artery stents, peripheral vascular stents, atrial septal defect occluders, and ventricular septal defect occluders. Through processes like plate rolling and laser cutting, they are shaped into high-precision grids or irregular structures, which, when implanted, effectively support blood vessel walls and seal defect areas. Their compatibility with blood and vascular tissues further minimizes postoperative complication risks.
IV. Surgical Instruments and Medical Equipment Field
In addition to implants, medical titanium alloy plates can also be used to manufacture high-demand surgical instruments and core components of medical equipment, leveraging their high strength and resistance to sterilization corrosion (tolerating various sterilization methods such as high-temperature and high-pressure steam sterilization, chemical disinfection, etc.), ensuring the stability and safety of performance during repeated use.
