First, tire fixation has no effect on the human body. The second is to fix it on the periosteum for life. Thirdly, it is taken out at 100% because it is solid. Fourth, it is hard to say that plastic materials are innovative, but at present, Gutai is the most advanced ideal material because:

In medicine, to evaluate the quality of an artificial material, it is best to meet the following standards:

1. Harmless to human body.

2. It has good compatibility and stability with human tissues. After being implanted into human tissues, it does not degrade, adhere or react.

3. It is easy to implant into human body during operation, and the operation is convenient.

4. When you don't want it, it's easy to take it out completely and cleanly.

5. Plastic is convenient for plastic surgeons to shape and carve into various desired shapes.

Such artificial materials are the best artificial materials. At present, there are few materials that meet the above five points, but they all meet the requirements of Gu Tai, so Dong Ping's periosteal patch is very good, don't worry! (ps: not a trust)
