Dental Biomaterials & Bioengineering

Commercially available dental biomaterials have passed all biocompatibility screening criteria, ensuring that they are low in toxicity, safe, clinically effective, and advantageous to patients. Because they were authorised through a grandfather approach, most dental biomaterials have never been assessed for biocompatibility. The grandpa procedure permits biomaterials to be sold and promoted without going through biocompatibility testing as long as they have the same chemical composition, sterilisation, manufacturing method, and quantity of body contact as marketed biomaterials.
