Although the selection of the repair materials in the operation is still controversial, the titanium mesh is widely applied to clinic by virtue of the advantages of easy molding, excellent biocompatibility, no magnetism, clear CT development, elastic modulus close to that of natural bones and the like. At present, the most common in clinic is the preformed titanium mesh of the Depuy Synthes company in America, which simulates the physiological forms of the inner wall and the bottom wall of the orbit, can effectively cover the fracture defect areas of the inner wall and the bottom wall after being implanted, recovers the anatomical structure and the form of the orbit, can be fixed in the middle of the lower edge of the orbit by a titanium nail, is particularly suitable for wide inner wall and bottom wall fracture, and is an ideal repairing material for the fracture of the orbit.
Although the titanium mesh is widely applied clinically, the existing preformed titanium mesh has certain defects that ① orbital wall structures are complex, the preformed titanium mesh has certain difference in shape relative to normal orbits before injury, and the recovery of orbital volume cannot be 100%, ② causes that surgeons often cannot accurately grasp fracture shapes due to the fact that an operation area is usually narrow, so that the process of trying to put and adjust the implants in the orbits is time-consuming and labor-consuming, the size edges of the implants need to be repeatedly trimmed and adjusted, secondary injury is easily caused, and complications are caused, ③ mid-facial fractures needing orbital floor repair by using the titanium mesh are often complex, and the final repair effect is easily influenced due to the fact that the orbital edges and the zygomatic bone body are not well restored when the titanium mesh is fixed.
