Abstract
Abstract The present invention provides a method of luting a provisional prosthetic device to tooth structure using glass ionomer cement systems having reduced bulk shear adhesion. The invention also provides a kit for luting a prosthetic device to tooth structure. The kit contains at least three containers of glass ionomer luting cement compositions. The kit advantageously can be utilized for providing both a provisional and a permanent luting cement depending upon which components are admixed.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
168 words
A method for luting a prosthetic device to tooth structure comprising the steps of (i) providing a kit containing components (A), (B), and (C), wherein said components comprise: (A) a composition comprising a water miscible, acidic polymer (B) a composition comprising a finely divided, acid-reactive filler and an adhesion reducing component such that when mixed with component (A), the Bulk Shear Adhesion of the resulting cement is less then 2.0 MPa (C) a composition comprising a finely divided, acid-reactive filler such that when mixed with component (A), the Bulk Shear Adhesion of the resulting cement is greater than 2.0 MPa (ii) determining whether a provisional luting cement is required or a permanent luting cement, (iii) if a provisional luting cement is required, mixing (A) with (B), and omitting step (iv), (iv) if a permanent luting cement is required, mixing (A) with (C), (v) applying the cement created by step (iii) or (iv) on the prosthetic device and/or the tooth structure, and (vi) bonding the device to tooth structure.
Claim 2
Independent Claim
168 words
A method for luting a prosthetic device to tooth structure comprising the steps of (i) providing a kit containing components (A), (B), and (C), wherein said components comprise: (A) a composition comprising a water miscible, acidic polymer (B) a composition comprising a finely divided, acid-reactive filler and an adhesion reducing component such that when mixed with component (A), the Bulk Shear Adhesion of the resulting cement is less then 2.0 MPa (C) a composition comprising a finely divided, acid-reactive filler such that when mixed with component (A), the Bulk Shear Adhesion of the resulting cement is greater than 2.0 MPa (ii) determining whether a provisional luting cement is required or a permanent luting cement, (iii) if a provisional luting cement is required, mixing (A) with (B), and omitting step (iv), (iv) if a permanent luting cement is required, mixing (A) with (C), (v) applying the cement created by step (iii) or (iv) on the prosthetic device and/or the tooth structure, and (vi) bonding the device to tooth structure.
