<p>A composition of restorative material, especially useful as dental filling material, comprising finely divided inorganic filler material and polymerizable monomer components is disclosed. Said composition contains (A) from about 50 to about 5% by weight of finely divided, inorganic filler material which is safe and effective for use in a dental filling in the human body, wherein at least 50% by weight of said filler material is at least the nitride substance having a Moh's hardness of at least 7 and is selected from the group consisting of vanadium nitride, boron nitride, aluminum nitride, silicon nitride, titanium nitride and zirconium nitride, and (B) from about 50 to about 5% by weight of polymerizable monomer component capable of polymerizing to form a binder resin for dental filling materials.</p> |
