Abstract
(DE) Die Erfindung schafft eine implantierbare Kiefergelenksteilprothese (90, 90', 90'') mit einem an einem Unterkiefer (40) befestigbaren ersten Implantatteil (10, 10', 10'') mit einem Gelenkkopf (42, 42', 42''), zu welchem eine an einem Cranium (50) angeordnete Gelenkfläche (52, 82) ein Widerlager bildet; wobei das erste Implantatteil (10, 10', 10'') eine aus einem metallischen Werkstoff gebildete erste Komponente (20, 20', 20'') aufweist, welche an dem Unterkiefer (40) befestigbar ist, und eine aus einem Kunststoff gebildete zweite Komponente (30, 30', 30'') aufweist, welche den Gelenkkopf (42, 42', 42'') aufweist; und wobei die erste Komponente (20, 20', 20'') mit einem ersten Verbindungsstück (22, 22', 22'') versehen ist und die zweite Komponente (30, 30', 30'') mit einem zweiten Verbindungsstück (32, 32', 32'') versehen ist, und das erste Verbindungsstück (22, 22', 22'') und das zweite Verbindungsstück (32, 32', 32'') ineinandergreifend zumindest bereichsweise formschlüssig lösbar miteinander verbindbar oder verbunden sind. Die Erfindung schafft ebenfalls ein entsprechendes Herstellungsverfahren und eine entsprechende Kiefergelenksprothese.
(EN) The invention relates to an implantable partial temporomandibular joint prosthesis (90, 90', 90'') having a first implant part (10, 10', 10'') that can be fastened to a lower jaw (40) and has a condyle (42, 42', 42'') with respect to which a joint surface (52, 82) situated on a cranium (50) forms an abutment; wherein the first implant part (10, 10', 10'') comprises a first component (20, 20', 20'') formed from a metal material, which first component can be fastened to the lower jaw (40), and a second component (30, 30', 30'') formed from a plastics material, which second component comprises the condyle (42, 42', 42''); and wherein the first component (20, 20', 20'') is provided with a first connection piece (22, 22', 22'') and the second component (30, 30', 30'') is provided with a second connection piece (32, 32', 32''), and the first connection piece (22, 22', 22'') and the second connection piece (32, 32', 32'') can be or are mutually engagingly detachably interconnected, at least partly interlockingly. The invention also relates to a corresponding production method and to a corresponding temporomandibular joint prosthesis.
