Hello, at present, the main filling materials for zygomatic augmentation surgery are: 1. Autologous bone graft filling: Autologous ilium and ribs may be absorbed. Autologous skull outer plate is less absorbed, but it increases the trauma and operation time of zygomatic height. 2. The filling of other biological bone substitutes is increased: including hydroxyapatite artificial bone, etc. In recent years, high-density porous polyethylene, a chemical synthetic material, has been processed into various specific shapes, which is easy to cut, shape and fix, and is the most widely used material for increasing cheekbones. However, some filling materials are expensive, which limits their wider clinical application.
