Abstract
Abstract The invention relates to the use of glass ionomer cements in a method of guided tissue regeneration. In the method, cavities are artificially created by forming glass ionomer cement coverings over bone substance defects, so that osseous regeneration can take place without a growing-in of connective tissue or bacteria colonization occurring in the bone defects.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
41 words
A method of guiding tissue regeneration, comprising: forming a tightly sealed, solid covering over a bone defect in vivo, wherein a cavity is formed between the covering and the bone defect, and wherein the covering consists of a glass ionomer cement.
Claim 2
Independent Claim
41 words
A method of guiding tissue regeneration, comprising: forming a tightly sealed, solid covering over a bone defect in vivo, wherein a cavity is formed between the covering and the bone defect, and wherein the covering consists of a glass ionomer cement.
Claim 3
Dependent Claim
24 words
A method of guiding tissue regeneration as recited in claim 1, wherein said bone defect occurs in the teeth or jaw of a patient.
Claim 4
Dependent Claim
36 words
A method of guiding tissue regeneration as recited in claim 1, wherein the glass ionomer cement comprises: (a) an aluminum fluorosilicate glass, (b) at least one polyacid with a molecular weight of >500, and (c) water.
Claim 5
Dependent Claim
40 words
A method of guiding tissue regeneration as recited in claim 1, wherein the glass ionomer cement comprises: (a) an aluminum fluorosilicate glass, (b) at least one polyacid with a molecular weight of >500, (c) water, and (d) a chelating agent.
Claim 6
Dependent Claim
41 words
A method of guiding tissue regeneration as recited in claim 1, wherein the glass ionomer cement comprises: (a) an aluminum fluorosilicate glass, (b) at least one polyacid with a molecular weight of >500, (c) water, and (d) at least one chemotherapeutic.
Claim 7
Dependent Claim
45 words
A method of guiding tissue regeneration as recited in claim 1, wherein the glass ionomer cement comprises: (a) an aluminum fluorosilicate glass, (b) at least one polyacid with a molecular weight of >500, (c) water, (d) a chelating agent, and (e) at least one chemotherapeutic.
Claim 8
Dependent Claim
33 words
A method of guiding, tissue regeneration as recited in claim 1, 3, 4, 5, or 6 wherein the glass ionomer cement is prepared by mixing together at least two spatially separate partial compositions.
Claim 9
Dependent Claim
44 words
A method of guiding tissue regeneration as recited in claim 7, wherein at least one of the partial compositions is present in a solid or powder form and at least one of the other partial compositions is present in a liquid or paste form.
Claim 10
Dependent Claim
46 words
A method of guiding tissue regeneration as recited in claim 8, wherein: the aluminum fluorosilicate glass is contained in a partial composition having a solid or powder form; and the polyacid and the water are contained in a partial composition having a liquid or paste form.
Claim 11
Dependent Claim
36 words
A method of guiding tissue regeneration as recited in claim 9, wherein: a chelating agent is present in the glass ionomer cement composition and is contained in the partial composition having a liquid or paste form.
Claim 12
Dependent Claim
46 words
A method of guiding tissue regeneration as recited in claim 8, wherein: the aluminum fluorosilicate glass and the polyacid are contained in a partial composition having a solid or powder form; and the water is contained in a partial composition having a liquid or paste form.
Claim 13
Dependent Claim
36 words
A method of guiding tissue regeneration as recited in claim 11, wherein: a chelating agent is present in the glass ionomer cement compositions and is contained in the partial composition having a solid or powder form.
Claim 14
Dependent Claim
36 words
A method of guiding tissue regeneration as recited in claim 11, wherein: a chelating agent is present in the glass ionomer cement compositions and is contained in the partial composition having a liquid or paste form.
