A bone implant (10) is implanted in a cavity parallel to an implant axis (I) and without substantial rotation. The implant includes, on an implant portion to be implanted, cutting edges (14), which do not extend in a common plane with the implant axis and are facing toward the distal end of the implant. The implant also includes surface ranges (16) of a material that is liquefiable by mechanical oscillations. The cutting edges (14) are dimensioned such that they are lodged in the cavity wall after implantation. For implantation, the implant is impinged with mechanical oscillations, resulting in the thermoplastic material being at least partially liquefied and pressed into unevennesses and pores of the cavity wall to form a form-fit and/or material-fit connection between implant (10) and cavity wall, when re-solidified. The cutting edges (14) anchor the implant in the cavity wall.

An anti-deformation structure is formed on the surface of a flexible plate-shaped part. The anti-deformation structure includes protrusions and depressions formed on the surface of the plate-shaped part. The protrusions and depressions has a shape in which adjacent protrusions become in contact with each other in the state when the plate-shaped part is deformed within a range of elastic deformation, restricting further greater deformation, and thus, preventing excessive deformation leading to permanent deformation and raising the resistance to the stress. The flexible base material can be applied to flexible image-displaying devices.

The predisposed portion of the body may be formed by modifying the material properties of the body, e.g., by localized heat treatment. The sleeve and related apparatuses and methods are useful for securing and protecting a cable having one or more insulated conductive wires for transmission of signals between locations downhole and at the surface.

The invention relates to a composition comprising a thermoplastic polymer and wood fiber composite that can be used in the form of a linear extrudate or thermoplastic pellet to manufacture structural members. The polymer, the fiber or both can be modified to increase compatibility. The wood fiber composite structural members can be manufactured in an extrusion process or an injection molding process.

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.
