Based on their behavior in living tissue, polymeric biomaterials can be divided into biostable, bioabsorbable (biodegradable or bioresorbable), and partially bioabsorbable materials.

In these cases, a high molecular weight, biostable polymeric carrier is preferred.

Here, we have focused the attention on PMMA because this polymer is considered a biostable polymer in biomedical applications.
