Abstract
Abstract In accordance with the invention there is provided a method, and a composition for the practice of the method, for repairing tooth or bone structure wherein there is applied to the tooth or bone tissue a composition comprising a polymerized or polymerizable organic phosphoryl monofluoride thereby to attain a strong bond to the tooth or bone tissue.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
62 words
A METHOD FOR TREATING TEETH OR BONE TISSUE INCLUDING THE STEP OF BONDING THERETO A BONE OR DENTAL FILLING COMPOSITION INCLUDING AT LEAST A SMALL BUT EFFECTIVE AMOUNT OF AN UNSATURATED ALIPHATIC ADDITION-POLYMERIZABLE ORGANIC PHOSPHORYL MONOFLUORIDE THEREBY TO INCREASE THE BOND STRENGTH OF SAID COMPOSITION TO SAID TISSUE, THE ORGANIC RADICAL OF SAID PHOSPHORYL MONOFLUORIDE CONTAINING ONLY OXYGEN, HYDROGEN AND CARBON ATOMS.
Claim 2
Independent Claim
62 words
A METHOD FOR TREATING TEETH OR BONE TISSUE INCLUDING THE STEP OF BONDING THERETO A BONE OR DENTAL FILLING COMPOSITION INCLUDING AT LEAST A SMALL BUT EFFECTIVE AMOUNT OF AN UNSATURATED ALIPHATIC ADDITION-POLYMERIZABLE ORGANIC PHOSPHORYL MONOFLUORIDE THEREBY TO INCREASE THE BOND STRENGTH OF SAID COMPOSITION TO SAID TISSUE, THE ORGANIC RADICAL OF SAID PHOSPHORYL MONOFLUORIDE CONTAINING ONLY OXYGEN, HYDROGEN AND CARBON ATOMS.
Claim 3
Dependent Claim
19 words
A method as set forth in claim 1 wherein said organic phosphoryl monofluoride contains at least one methacrylic group.
Claim 4
Dependent Claim
18 words
A method as set forth in claim 2 wherein said organic phosphoryl monofluoride is glycerol dimethacrylate phosphoryl monofluoride.
Claim 5
Dependent Claim
24 words
A method as set forth in claim 1 wherein said composition also includes an organic polymer material other than said addition-polymerizable organic phosphoryl monofluoride.
Claim 6
Dependent Claim
17 words
A method as set forth in claim 4 wherein said composition further includes finely divided solid material.
Claim 7
Dependent Claim
17 words
A method as set forth in claim 1 wherein said composition also includes catalyst to cause polymerization.
Claim 8
Dependent Claim
27 words
A method as set forth in claim 1 wherein said composition also includes another organic polymeric material, finely divided solid material, and a catalyst to cause polymerization.
Claim 9
Dependent Claim
29 words
A method as set forth in claim 7 wherein said phosphoryl monofluoride contains at least one methacrylic group and wherein said other organic polymeric material also contains methacrylic groups.
Claim 10
Independent Claim
58 words
A method for filling a tooth cavity comprising applying to the walls of the tooth cavity a lining composition comprising an unsaturated aliphatic addition-polymerizable organic phosphoryl monofluoride and then filling the remainder of the cavity with a filling composition including an organic polymeric material, the organic radical of said phosphoryl monofluoride containing only carbon, hydrogen and oxygen atoms.
Claim 11
Independent Claim
58 words
A method for filling a tooth cavity comprising applying to the walls of the tooth cavity a lining composition comprising an unsaturated aliphatic addition-polymerizable organic phosphoryl monofluoride and then filling the remainder of the cavity with a filling composition including an organic polymeric material, the organic radical of said phosphoryl monofluoride containing only carbon, hydrogen and oxygen atoms.
Claim 12
Dependent Claim
36 words
A method as set forth in claim 9 wherein the organic polymeric material in said filling composition and said addition-polymerizable organic phosphoryl monofluoride are caused to simultaneously polymerize in situ after being applied to the tooth.
Claim 13
Dependent Claim
19 words
A method as set forth in claim 9 wherein the lining composition also includes a catalyst to cause polymerization.
Claim 14
Dependent Claim
29 words
A method as set forth in claim 9 wherein said lining composition also includes finely divided solid material and organic polymeric material other than said addition-polymerizable organic phosphoryl monofluoride.
Claim 15
Dependent Claim
19 words
A method as set forth in claim 9 wherein said organic phosphoryl monofluoride contains at least one methacrylic group.
Claim 16
Dependent Claim
16 words
A method as set forth in claim 9 wherein said lining composition also contains a silane.
Claim 17
Dependent Claim
22 words
a method as set forth in claim 9 wherein the organic phosphoryl monofluoride in said lining composition is glycerol dimethacrylic phosphoryl monofluoride.
Claim 18
Dependent Claim
37 words
A method as set forth in claim 12 wherein said finely divided material has a coefficient of thermal expansion which causes the coefficient of thermal expansion of the lining composition to substantially match that of the tooth.
