How to distinguish these rhinoplasty materials? The following Han Hou Han Hou plastic rhinoplasty experts tell you! The content of copyright DEDEECMS comes from the development of DEDEECMS in rhinoplasty, and the rhinoplasty materials are gradually enriched. Here are several common rhinoplasty materials, hoping to help you choose. Rhinoplasty material 1. Dental materials The dental materials used for rhinoplasty are polymethacrylic acid and methyl ester (PMMA), which are one of the solid biological tissue substitutes used for rhinoplasty earlier. Good biocompatibility, it needs to be blended when it is used for rhinoplasty, and it is very easy to be polluted. If the pollution is not completely removed before operation, it will easily lead to complications such as infection, pain and rejection. Its prosthesis preparation is complex and the operation is relatively difficult, so it is rarely used at present. Rhinoplasty materials II. Ivory has a good dream weave, and a good dream weave ivory has good biocompatibility and generally does not cause rejection. However, it was gradually abandoned for rhinoplasty because of its high hardness, difficulty in carving and shaping, and protection of animals. Rhinoplasty material III. Solid silica gel is a commonly used rhinoplasty material and a polymer silicide. It was used as early as 1972. After more than 20 years of observation, although the incidence of complications can reach 5%-20%, it is still one of the first choice materials for rhinoplasty because of its good biocompatibility and low price. Its main disadvantage is that it can not establish blood circulation with the body and form tissue connection, and it is only wrapped by fibrous tissue, so it can penetrate the skin at weak tissue. Due to the contracture of fibrous capsule, it can cause the surface of silicone prosthesis to protrude, which affects the appearance effect.

Fourthly, expanded polytetrafluoroethylene (ePTFE) comes from dedecms, which is the most ideal biological tissue substitute from the medical point of view. Because of its good biocompatibility and unique microporous structure, it is non-toxic, non-carcinogenic and non-allergenic. Human tissue cells and blood vessels can grow into its micropores to form tissue connections, just like autologous tissue. The effect of rhinoplasty with it is satisfactory. Expanded PTFE rhinoplasty material was introduced into China from the United States on 1995, but its high price affected its universal application. Rhinoplasty Materials V. dedecms.com, an artificial bone material, mainly refers to hydroxyapatite. It is the main inorganic component of human bone tissue, so it has good biocompatibility and no side effects such as teratogenesis, sensitization and carcinogenesis. It has been widely used in stomatology and orthopedics. It has been used for rhinoplasty since the mid-1980s. It is easy to operate and shape, especially for people with low nose bridge. The effect after rhinoplasty is particularly satisfactory. Because there is no supporting effect, it has poor effect on people with low nasal tip.
