Abstract

Abstract A bioresorbable device for use in regeneration of at bone and/or tissue in either a bone void or a tissue deficiency is provided. A primary embodiment is a bioresorbable periodontal barrier for use in regeneration of a periodontal bone and/or tissue in either a gingival pocket adjacent to a patient's tooth or an edentulous area. The bioresorbable periodontal barrier includes a formable membrane constructed of a bioresorbable material and having a microstructure configured for aiding and guiding periodontal tissue growth, and a bioresorbable hardening agent pre-impregnated in the membrane. The membrane is formed to a desired shape and the hardening agent is activated to harden so that the membrane retains the desired shape. A method of assisting bone and/or tissue regeneration in either a bone void or tissue deficiency is also provided. A primary embodiment is a method of assisting and guiding periodontal bone and/or tissue regeneration in a gingival pocket adjacent to a patient's tooth or in an edentulous area. The method includes implanting a barrier over the gingival pocket, forming the membrane into a desired shape which covers the gingival pocket, and allowing the periodontal bone and/or the periodontal tissue to regenerate into the enclosed gingival pocket.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 91 words
A bioresorbable barrier for use in regeneration of at least one of periodontal bone and tissue in a gingival pocket being one of adjacent to a patient's tooth and in an edentulous area, said barrier comprising: a formable membrane constructed of a bioresorbable material and having a microstructure configured for aiding and guiding periodontal bone and periodontal tissue growth, wherein said membrane comprises a woven mesh including strands; and an activatible bioresorbable hardening agent impregnated within said membrane, said hardening agent being activated to hold said membrane in a desired shape.
Claim 2
Dependent Claim 91 words
A bioresorbable barrier for use in regeneration of at least one of periodontal bone and tissue in a gingival pocket being one of adjacent to a patient's tooth and in an edentulous area, said barrier comprising: a formable membrane constructed of a bioresorbable material and having a microstructure configured for aiding and guiding periodontal bone and periodontal tissue growth, wherein said membrane comprises a woven mesh including strands; and an activatible bioresorbable hardening agent impregnated within said membrane, said hardening agent being activated to hold said membrane in a desired shape.
Claim 3
Dependent Claim 13 words
The barrier as recited in claim 1, wherein said hardening agent is plaster.
Claim 4
Dependent Claim 20 words
The barrier as recited in claim 1, wherein and said hardening agent is activated by moistening said barrier with water.
Claim 5
Dependent Claim 28 words
The barrier as recited in claim 1, wherein said desired shape encloses a regeneration space and said hardening agent prevents said membrane from collapsing into said regeneration space.
Claim 6
Dependent Claim 21 words
The barrier as recited in claim 1, wherein said barrier is pre-formed into one of a plurality of shapes and sizes.
Claim 7
Dependent Claim 16 words
The bioresorbable barrier as recited in claim 1, wherein said membrane further comprises a beaded rim.
Claim 8
Independent Claim 121 words
A method of assisting and guiding at least one of periodontal bone and tissue regeneration in a gingival pocket being one of adjacent to a patient's tooth and in an edentulous area, comprising the steps of: providing a barrier comprising a formable membrane constructed of a bioresorbable material and having a microstructure configured for aiding and guiding periodontal bone and periodontal tissue growth, wherein said membrane comprises a woven mesh including strands, and an activatible bioresorbable hardening agent impregnated within said membrane; implanting said barrier about said gingival pocket; forming said membrane into a desired shape which covers said gingival pocket; and allowing at least one of said periodontal bone and said periodontal tissue to regenerate into said enclosed gingival pocket.
Claim 9
Independent Claim 121 words
A method of assisting and guiding at least one of periodontal bone and tissue regeneration in a gingival pocket being one of adjacent to a patient's tooth and in an edentulous area, comprising the steps of: providing a barrier comprising a formable membrane constructed of a bioresorbable material and having a microstructure configured for aiding and guiding periodontal bone and periodontal tissue growth, wherein said membrane comprises a woven mesh including strands, and an activatible bioresorbable hardening agent impregnated within said membrane; implanting said barrier about said gingival pocket; forming said membrane into a desired shape which covers said gingival pocket; and allowing at least one of said periodontal bone and said periodontal tissue to regenerate into said enclosed gingival pocket.
Claim 10
Dependent Claim 24 words
The method as recited in claim 7, further including the step of activating said hardening agent to maintain said desired shape of said membrane.
Claim 11
Dependent Claim 27 words
The method as recited in claim 8, wherein said hardening agent is plaster and said step of activating said hardening agent includes moistening said barrier with water.
Claim 12
Dependent Claim 37 words
The method as recited in claim 7, wherein said step of forming said membrane includes forming a regeneration space encompassed by said gingival pocket and a support surface to prevent gingiva from collapsing into said regeneration space.
Claim 13
Dependent Claim 81 words
A bioresorbable device for use in regeneration of at least one of bone and tissue in one of a bone void and a tissue deficiency, said barrier comprising: a formable membrane constructed of a bioresorbable material and having a microstructure configured for aiding and guiding bone and tissue growth, wherein said membrane comprises a woven mesh including strands; and an activatible bioresorbable hardening agent impregnated within said membrane, said hardening agent being activated to hold said membrane in a desired shape.
Claim 14
Dependent Claim 81 words
A bioresorbable device for use in regeneration of at least one of bone and tissue in one of a bone void and a tissue deficiency, said barrier comprising: a formable membrane constructed of a bioresorbable material and having a microstructure configured for aiding and guiding bone and tissue growth, wherein said membrane comprises a woven mesh including strands; and an activatible bioresorbable hardening agent impregnated within said membrane, said hardening agent being activated to hold said membrane in a desired shape.
