An implant or endoprosthesis suitable to be implanted in human or animal tissue includes two (or more than two) parts to be joined in situ. Each one of the parts includes a joining location, the two joining locations facing each other when the device parts are positioned for being joined together, wherein one of the joining locations includes a material which is liquefiable by mechanical vibration and the other one of the joining locations includes a material which is not liquefiable by mechanical vibration and a structure (e.g. undercut cavities or protrusions) suitable for forming a positive fit connection with the liquefiable material. The joining process is effected by pressing the two device parts against each other and by applying ultrasonic vibration to one of the device parts when the two parts are positioned relative to each other such that the two joining locations are in contact with each other.

A dental implant system for supporting a cosmetic tooth prosthesis includes an elongated body adapted to be disposed in a jaw bone of a patient. The elongated body includes a distal end and a proximal end and extends along a longitudinal axis. The elongated body includes a tapered outer surface that tapers along the longitudinal axis distally from the proximal end of the elongated body. The outer surface of the tapered elongated body includes a plurality of barbs for securing the elongated body in the jaw bone of the patient.

A method for locating a material having thermoplastic properties in pores of bone tissue includes providing a pin having the material having thermoplastic properties and a core, wherein the material having thermoplastic properties is arranged on the circumferential surface of the core constituting an outer region of the pin. An opening is provided in the bone tissue, and the pin is positioned at least partly in the opening. The outer region of the pin is then impinged with mechanical vibration energy for a time sufficient for liquefying at least part of the material having thermoplastic properties, and, in a liquefied state, pressing it into the pores of the bone tissue surrounding the opening. The vibration energy is stopped for a time sufficient for re-solidification of the liquefied material, and then the core is removed.

A method of preparing a bone graft of compressed dehydrated decalcified trabecular bone may include compressing the bone while hydrated from a first form to a second form such that the bone in the second form is compressed relative to the first form. The bone may be dried while compressed. When dry, the bone substantially retains the second form and does not revert to the first form when the compression is removed.

An abutment is obtained that enables an operation of detaching the abutment from a fixture to be readily performed without having a patient open his/her mouth wide while inhibiting accidental ingestion or swallowing of an abutment that comes off. In a dental implant 100 comprising a fixture 110 and an abutment 120, when a fitting recess 121 of the abutment 120 is fitted onto a fixture head 112 so that a space is formed between a top surface 112b 1 of the fixture head 112 and a bottom surface 121a of the fitting recess 121, the fixture head 112 is secured to the fitting recess 121 by a frictional force, and an instrument insertion hole 129 for inserting an instrument for disengaging the securement by the frictional force in the space is formed on a sidewall 121c of the fitting recess 121.

The present invention relates to a mounting element (10) for fixing removable tooth prostheses which are anchored by an implant, comprising a lower end (13) for fastening the mounting elements (10) having an implant (21) or abutment; and an upper end for connecting the mounting element having a tooth prosthesis, optionally a friction insert; characterised in that the main body of the mounting element (10) has an outer ring (11).

A process for producing a ceramic body (100), in particular a dental ceramic blank, having selectively adjustable degrees of expression of one or more different physical properties, wherein the ceramic body (100) has a porosity to enable the control of a selective distribution of one or more chemical substances (101, 102) that are suitable for influencing the physical properties of the ceramic body (100), and in a first step, which is a loading step, the ceramic body is loaded with one or more solutions (104) of the one or more chemical substances (101, 102). In a second step, which is a distribution step, the distribution of the one or more chemical substances (101, 102) within the porous ceramic body (100) is controlled, wherein a progression and/or a spatial progression of the degree of expression of the one or more physical properties can be produced. The control is effected by adjusting one or more ambient parameters (106) in an environment (108), in particular by adjusting the air humidity and/or the pressure and/or the temperature.

A dental implant two-piece fixture mount has an implant fixture-mount base portion at its distal end and a snap-on, separate, separable top piece at its proximal end.

A dental implant device for insertion into a bore defined in bone for use with a prosthetic tooth or dental appliance includes an abutment with a plurality of male keys disposed about the distal end of the abutment capable of being affixed to the prosthetic tooth or dental appliance, an implantable anchor having a proximal and distal end, a plurality of female keyways defined into the proximal end of the anchor, the keyways capable of coupling to the male keys of the abutment and thereby preventing relative rotation of the abutment and anchor; an interlocking thread helically defined around a longitudinal axis of the anchor, the thread being adapted to couple to the bore defined in the bone and means for coupling the abutment to the implant anchor.
