Q

what is the biggest issue with using biomaterials?

A

synthetic materials are placed in a living environment where they don’t belong - they are foreign
synthetic materials are being placed in contact w living tissue - interfacial problems may occur

21
Q

the general philosophy is that dental biomaterials do not belong in the mouth. therefore….

A

all synthetic dental materials have limitations

22
Q

the lack of durability of biomaterials in comparison to human tissues emphasizes the importance of:

A

prevention
conservative tx
longevity of restorations

23
