PREPARATION FOR FIXING TO A NATURAL PIECE OF TOOTH OR TO A TOOTH AND CORRESPONDING FIXING METHOD

摘要

A preparation for being fixed to a natural tooth part has surface regions consisting of a material with thermoplastic properties. The preparation has oscillation properties with damping losses that are so small that local stress concentrations are required for liquefying the material by oscillation, the preparation being designed such that the stress concentrations only occur in the region of the preparation surface. The preparation is positioned on a suitably prepared natural tooth part such that the material with the thermoplastic properties is in contact or may be brought into contact with the dentin surface and/or enamel surface. The preparation is then made to mechanically oscillate and is simultaneously pressed against the natural tooth part, whereby the material with the thermoplastic properties is at least partly liquefied and brought into intimate contact with the dentin or enamel surface such that, after solidification, it forms a positive fit and/or material fit connection.
