If you want a cost-effective one, choose silicone. However, personally, I prefer bulk. First of all, many people choose bulk, because bulk is soft and opaque, which is more conducive to doctors' carving.
And now many kinds of materials have been developed. If you pay attention to this piece, you will find some new prostheses such as mesh, Shubo and Shejifeng. , are extended by bulking. Personally, I think that bulkiness is a trend whether it is used for simple chin pads or plastic materials in the future. Of course, swelling also has its downside, that is, there are many tiny holes on the surface, which can easily grow with human tissues. The chin is not well done, and it is more susceptible to infection when it is taken out.
This requires strict screening of surgeons. I really like to see the cases of rhinoplasty by several deans. You can go and have a look. As for silicone, I have also paid attention to it before. It is really great that it is not easy to deform as an old prosthesis. Both have their advantages and disadvantages. I hope you can choose the prosthesis that suits you.
