Abstract:
1. A kit comprising a plurality of (a) temporary supraconstructions, (b) preformed blanks for temporary supraconstructions or (c) combinations of a respective core for a temporary supraconstruction and an associated cap blank, wherein each of said (a) temporary supraconstructions, (b) preformed blanks for temporary supraconstructions or (c) the combinations of the respective cores for said temporary supraconstructions and said associated cap blank comprise an occlusal surface and a material having a modulus of elasticity of less than 300 M Pa, and wherein each of (a) said temporary supraconstructions, (b) said preformed blanks for temporary supraconstructions or (c) combinations of said respective cores for the temporary supraconstructions and said associated cap blank comprise materials having different moduli of elasticity values, hardness values, or both, wherein the different moduli of elasticity are from at least two ranges selected from the group consisting of (i) 15 to 40 MPa, (ii) 55 to 70 MPa and (iii) 100 to 120 MPa, and the different hardness values are selected from at least two ranges selected from the group consisting of (i) Shore A hardness 25-45, (ii) Shore A hardness 75-85, and (iii) Shore D hardness 35-45, wherein the materials are obtained by hardening a starting material, wherein the starting material comprises the following constituents: (a) one or more silicones comprising polyatomic crosslinkable groups and/or one or more substituted or unsubstituted crosslinkable polyethers, and (b) one or more catalysts or starters for causing crosslinking of the crosslinkable groups of constituent (a).
