    • Am implant (1), in particular a dental implant, comprises surface regions (4) of a first type which have osseo-integrative, inflammation-inhibiting, infection-combating and/or growth-promoting properties, and surface regions (8) of a second type which consist of a material which is liquefiable by mechanical oscillations. The implant is positioned in an opening of e.g. a jawbone and then mechanical oscillations, e.g. ultrasound is applied to it while it is pressed against the jawbone. The liquefiable material is such liquefied at least partly and is pressed into unevennesses and pores of the surrounding bone tissue where after resolidification it forms a positive-fit connection between the implant and the bone tissue. The surface regions of the two types are arranged and dimensioned such that, during implantation, the liquefied material does not flow or flows only very little over the surface regions of the first type such enabling the biologically integrative properties of these surface regions to start acting directly after implantation. The dental implant comprises a central implant part (1) which for example consists of titanium, which comprises at its proximal end a fixation location (3) or an artificial tooth crown, and which forms the surface regions (4) of the first type. Furthermore the implant comprises a peripheral implant part (2) which consists of a liquefiable material and forms the surface regions (8) of the second type. The dental implant achieves with the help of the positive fit a very good (primary) stability which is later taken over by the (secondary) stability of the osseointegration when resorbable liquefiable materials are used or which is supplemented by the stability of osseointegration when non-resorbable liquefiable materials are used.

    • A preparation (10, 11,12,13) to be fixed to a natural tooth part or tooth, in particular for the replacement of a load-bearing tooth part, is for example a filling for a drilled-out tooth (1), a crown, bridge or prosthesis to be placed on a tooth stub, or a tooth pin to be fixed in a tooth root for fastening an artificial tooth, a bridge or a prosthesis. The preparation has surface regions which consist of a material with thermoplastic properties. The preparation (10, 11, 12,13) is designed in a manner such that it has oscillation properties with such low damping losses that for a liquefaction of the material with thermoplastic properties by way of oscillations there are local stress concentrations required, and in a manner such that such stress concentrations only occur in the region of the preparation surface. The preparation is positioned on a suitably prepared natural tooth part in a manner 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 in a manner such that after solidification it forms a positive fit and/or material fit connection. Teeth restored with such preparations have a high stability and a long life, which in particular is attributed to the fact that the thermoplastic material, in contrast to cements used for the same purpose, shrinks less and has the ability to relieve internal stress by creeping.
