Different materials, the price will definitely be different, so I suggest you understand the relevant content! Temple filling (frontotemporal filling) is an operation in which synthetic materials or autologous tissues are implanted into the tissues in the depressed or defective parts to make them bulge and achieve a satisfactory appearance. From the point of view of human anatomy and physiology, whatever tissue is missing should be supplemented. All the indications listed above are caused by frontotemporal bone dysplasia. The frontotemporal bone defect can be filled with hard materials. Such as autogenous bone and synthetic materials (tissue substitutes), the most commonly used substitutes in clinic are medical solid silica gel, expanded polytetrafluoroethylene (Gore-TEX) and expanded polyethylene (Medpor). The former is easy to carve and cheap. The latter two have good histocompatibility, and there are micropores on the surface of the prosthesis, which is beneficial to tissue growth and firmer fixation. It can also be filled with soft materials, such as autologous fat, hyaluronic acid and collagen.
