Medical titanium in plastic surgery application
Titanium non-toxic, non-magnetic properties, the elastic modulus of titanium alloy and human bones similar elastic modulus, and the human body has good compatibility, it is also known as "bio-metal." Titanium is also an important member of the family of memory alloy, nickel-titanium alloy is the earliest discovery of a memory of the alloy, the alloy can "remember" his own head, it is subject to external deformation, as long as the corresponding temperature, and Can "postpone Meng Meng" to restore the prototype. And because it contains titanium, its strength is equally high. As a result, this alloy has become the most versatile memory alloy and today, it remains one of the best performing shape memory alloys. With titanium and titanium screws for fractures, unexpected results, just a few months, the new bone and muscle will be associated with the titanium. Therefore, titanium is suitable for human dental implants and artificial joint materials.
Zygomatic plastic surgery mainly includes two concepts: one is a simple zygomatic chisel, to narrow the outer contour of the zygomatic; the other is a three-dimensional osteotomy, shortening and movement through the bone block to achieve zygomatic shrinkage. Zygomatic chisel surgery, generally suitable for patients with anterior facial protrusion, often using intra-oral incision, the subperiosteal dissection exposed zygomatic bone, the use of special equipment to preoperative design to be removed part of the zygomatic chisel to thin, so as to narrow Facial contour, improve the face. The use of titanium nails, titanium plate is fixed to the cheekbones will not cause slippery, resulting in facial contours lost, but also to better achieve the effect of zygomatic shape!
The biggest advantage of this operation is that after surgery without leaving a scar, perfect, leaving no trace. Zygomatic three-dimensional osteotomy surgery is greatly increased the difficulty, suitable for patients with prominent zygomatic arch. In addition to intraoral incision, usually in the hairline to make a hidden part of the auxiliary incision, or single scalp incision, periosteal separation of the entire exposed zygomatic bone, in accordance with the requirements of three-dimensional computer simulation design to cut off a specific size of the bone, Re-use of titanium nail and other special materials will be separated bone reconnection and shaping, so as to maximize the change of the entire face contour and face, and even allow patients to achieve "reborn" effect. In addition to zygomorphous surgery, for a small number of patients due to congenital or acquired diseases caused by zygomatic dysplasia or defect caused by the local central depression, or both sides of the zygomatic asymmetry, can be autologous tissue transplantation or leave Body material filling zygomatic zygomatic augmentation for treatment, in order to achieve the purpose of improving the appearance.
1, Titanium has served as a new material in the fields of pharmaceutical industry, surgical instruments and human implants in China and the rest of the world for several decades and has achieved great success.
2, the body should be trauma, tumors caused by bone and joint damage, the use of titanium and titanium alloys can be manufactured artificial joints, bone plates and screws are now commonly used in clinical. It is also used in the hip joint (including femoral head), knee joint, elbow joint, metacarpophalangeal joint, interphalangeal joint, mandible, artificial vertebral body (spine orthosis), cardiac pacemaker housing, artificial heart Artificial dental implant, and titanium mesh in cranial plastic surgery and so on.
3, the requirements for implant materials can be grouped into three aspects: the biocompatibility of materials and human body, the material corrosion resistance in the human environment and the mechanical properties of materials
