This is indeed a question hard to answer; I believe many doctors will have different answers. My personal opinion is to go back to the structural characteristics and the location you would like to reconstruct to determine the answer. If it is sunken or shorter bones (for example the chin and the jaw, etc.), using a harder artificial bone to fill in fits the physiological characteristics better. This type of material will combine securely with bones three months after implanting, you will not feel it, and do not need to worry about it shifting after time. Of course silica bone still have the attributes of easy implanting and lower costs; what type you should use is determined by your needs and the judgment of the surgeon.
