Property of a material which is compatible with living tissue.
A biocompatible material is not toxic, nor does it generate an adverse reaction in the body or tissue it is in contact with.
Biocompatibility is a key property of materials used in medical devices and is measured in accordance with ISO 10993. The range of tests to be carried out for a biocompatibility evaluation depends on the nature and the duration of the contact between the device and the body. Hence, the tests to be performed will be different for a dental aligner material and a bone implant material.
In DLP 3D-printing, the development of biocompatible photopolymer resins is a prerequisite for the expansion of this technology in the fields of biofabrication and bioprinting. Recent developments in material research have enabled the emergence of new non-toxic photopolymer formulations and photopolymerization techniques that pave the way for promising applications in tissues engineering ang regenerative medicine.
