The wide application of pure titanium wire in the medical and dental fields

Pure titanium wire (commercial pure titanium Gr1-Gr4) has become an indispensable material in the medical and dental fields due to its outstanding biocompatibility, corrosion resistance, lightweight and excellent mechanical properties. It plays a significant role in multiple aspects such as surgical implantation, dental restoration, orthodontic treatment, and medical device manufacturing, providing patients with a safe, comfortable and efficient treatment experience.

Application Fields
(1) Surgical implants
Pure titanium wire plays a significant role in orthopedics, maxillofacial surgery and cardiovascular surgeries. In fracture repair surgery, it is used as a bone nail and bone plate fixation wire. With its biological inertness, it avoids rejection reactions. At the same time, it will not corrode even after long-term implantation, providing stable support for bone healing. In maxillofacial surgery, titanium can be used for the repair of the zygomatic bone, mandible and other parts, providing reliable support structures. In addition, extremely fine titanium wires (0.1-0.3mm) are also used to cover the leads of cardiac pacemakers, reducing tissue reactions and enhancing long-term safety.

(2) Dental Implants and Restorations
In the field of dentistry, pure titanium wire is also widely used. It can be used as an implant connection wire to ensure the temporary or permanent fixation of the implant to the abutment and guarantee stability. In the production of removable partial dentures (RPD), titanium wire can be bent into shape to make retaining rings and brackets. Compared with traditional cobalt-chromium alloys, it is lighter and more comfortable. In addition, titanium wire can also be used in periodontal splints, providing stable mechanical support for the recovery of periodontal tissues by binding loose teeth.

(3) Orthodontic treatment
Pure titanium wire also has significant advantages in orthodontics. It can be used as a corrective archwire to replace some stainless steel wires. With a moderate elastic modulus, it provides continuous and gentle corrective force, reducing patient discomfort. In addition, its corrosion resistance makes it particularly suitable for use in lingual orthodontic wires, preventing performance from being affected by saliva corrosion and enabling it to function stably in the oral environment for a long time.

(4) Surgical suturing and minimally invasive medical treatment
Ultra-fine titanium wire (<0.1mm) can be used as surgical sutures in cardiovascular or neurosurgical operations, providing high-strength tissue suturing while reducing inflammatory responses. In minimally invasive surgeries, titanium wire can also be used as a guide wire to help the catheter be precisely positioned. For instance, in vascular stent implantation, its excellent performance provides a strong guarantee for the smooth progress of the surgery.

(5) Other medical devices
Pure titanium wire is also used to manufacture the support structure of flexible endoscopes, which is both elastic and resistant to disinfection, ensuring the stability and durability of the endoscope during use. In addition, it is also used in the components of surgical instruments, such as forceps and the spring parts of needle holders. It is corrosion-resistant and has a long service life, further expanding its application scope in the medical field.
