Patent number: 5678995Abstract: An enossal implant includes a base member, a one-piece spacer member and tening head which has a skeleton structure composed of metal and plastic material. The spacer sleeve has a blind bore with threads in the fastening head portion for receiving a threaded implant post. The skeleton structure has cavities in a metal body filled with an elastic plastic material to enable the spacer sleeve to be compressed in an axial direction and also to bend in response to bending stresses.Type: GrantFiled: September 20, 1995Date of Patent: October 21, 1997Assignees: IMZ Fertigungs- und Vertriebs gesellschaft fuer dentale Technolgie mbH, Eberle Medizintechnische Elemente GmbHInventors: Axel Kirsch, Walter Durr

Patent number: 5544552Abstract: A fastening nail for fixing a cover membrane to a bone void which surrounds the bone of the body itself and is filled with an ossiferous material has a nail head with a larger diameter which enables receiving pressure of an impact tool for inserting a nail shaft with a smaller diameter into the bone. The nail shaft has essentially a cylindrical holding part extending to a conical tapering point part adjacent one end and is provided with a transition region between the holding part and point part having an annular shoulder with an enlarged diameter which has a conical surface merging obliquely with the generated surface of the point part in a direction toward the point of the nail and an annular surface extending substantially perpendicular relative to the holding axis of the nail. To insert the nail, the setting tool is elongated and has resilient jaws for gripping the nail and is used in combination with an auxiliary tool which has a foot with downwardly extending points for holding the membrane on the bone.Type: GrantFiled: June 2, 1995Date of Patent: August 13, 1996Assignees: Axel Kirsch, Eberle Medizintechnische Elemente GmbHInventors: Axel Kirsch, Walter Duerr

Patent number: 5026285Abstract: An implant for an individual tooth including a metal implant post having a fastening head for receiving the removable denture, the implant post being mounted in a metal spacing element which is threaded in a basic structure that is implantable in the tooth. To hold the spacing element in a fixed, non-twisting and rotatable position, the element is composed of a base portion having a first threaded portion which is received in the basic structure and a second threaded portion of a pitch less than the first portion, which receives a ring element that is threaded thereon and has a shoulder for engaging an upper edge of the basic structure to form a locking arrangement.Type: GrantFiled: April 18, 1990Date of Patent: June 25, 1991Assignees: Axel Kirsch, Eberle Medizintechnische Elemente GmbHInventors: Walter Durr, Axel Kirsch
