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.
