Today, titanium alloy plates are being used more widely in the medical field.In some developed countries and world famous implant product suppliers attach great importance to the research and development of titanium alloy, and have launched a series of new medical titanium alloy materials, including bionic titanium alloy materials with biological activity. In the aspect of surface treatment of medical titanium alloy materials, many patent design and development have also been done. To give medical titanium alloy material better biological activity to meet the physiological needs of the human body, so as to achieve the purpose of early recovery of patients. For example, zygomatic plastic surgery mainly includes two concepts: one is simple zygomatic chiselling to reduce the external contour of the zygomatic bone; The other type is three-dimensional osteotomy, which reduces the zygomatic bone by shortening and moving the bone mass. Cheekbone chipping is generally suitable for patients with anterolateral facial protrusion. Intraoral incision is often used to separate and expose the cheekbones under periosteal. Special instruments are applied to chipping and thinning the cheekbones designed to be removed before surgery, so as to reduce the external contour of the face and improve the facial shape. The use of titanium nails, titanium plate fixation is in order to cheekbone will not cause slip, resulting in facial contour loss, but also can better achieve the effect of cheekbone shaping! The best thing about this surgery is that it leaves no scar, no trace. However, the difficulty of zygomatic three-dimensional osteotomy is greatly increased, which is suitable for patients with zygomatic arch protrusion. In addition to the intra-oral incision, auxiliary incision is usually made in the hidden part of the hairline, or a single intra-scalp coronal incision. After subperiostium separation and exposure of the entire zygomatic bone, bone blocks of specific size are cut off according to the three-dimensional computer simulation design, and titanium nails and other special materials are used to reconnect and shape the separated bone blocks, so as to maximize the change of the contour and facial shape of the whole face. Even let the patient achieve the effect of "transformation".
