Claims
- 1. A method for forming a hardened substance on teeth comprising the steps of:
- (i) applying to said teeth a dental material comprising a polymerizable material, said polymerizable material comprising at least 10% by weight of a dimethacrylate of the chemical structure: ##STR11## where R.sub.1 and R.sub.2 may be the same or different and are cyclohexyl or phenyl groups which may be substituted or unsubstituted; and
- R.sub.3 is an aliphatic, cycloaliphatic or aromatic group having 6 to 15 carbon atoms; and
- (ii) polymerizing said polymerizable material in situ.
- 2. A tooth comprising a polymer of a dimethacrylate of the following chemical structure: ##STR12## where R.sub.1 and R.sub.2 may be the same or different and are cyclohexyl or phenyl groups which may be substituted or unsubstituted; and
- R.sub.3 is an aliphatic, cycloaliphatic or aromatic group having 6 to 15 carbon atoms.
- 3. A method according to claim 1 wherein the polymerizable material is a composite restorative material comprising glass or ceramic filler and polymerizable material,
- said polymerizable material comprising at least one first monomer and at least one second monomer,
- said first monomer being a dimethacrylate of the following chemical structure: ##STR13## where R.sub.1 and R.sub.2 may be the same or different and are cyclohexyl or pheny groups which may be substituted or unsubstituted and
- R.sub.3 is an aliphatic, cycloaliphatic or aromatic group having 6 to 15 carbon atoms,
- said second monomer being a diluent selected from the group consisting of di- and trimethacrylates having from 10 to 18 carbon atoms,
- said diluent further being selected from the group consisting of alkylene glycol dimethacrylates, polyalkylene glycol dimethacrylates and alkanetriol trimethacrylates.
- said at least one first monomer constituting at least 20% by weight of said polymerizable material,
- said at least second monomer constituting at least 10% by weight of said polymerizable material, and
- the weight ratio of said filler to said polymerizable material being from about 1.5:1 to about 8.5:1.
- 4. A method according to claim 1 wherein the polymerizable material comprises at least 10% by weight of said dimethacrylate, the remainder of said polymerizable material being at least 10% by weight of at least one acrylic methacrylic monomer acceptable for oral application associated with dental treatment.
