Abstract: Enossal tooth implant for firmly seating dental prostheses has an essentiy cylindrical base member, which is introducible into a bore introduced in a jaw bone and has a blind bore open toward its coronal end, a spacer sleeve which has an inside bore, is emplaceable on a coronal face edge of the base member and has an arrangement for a twist-resistant fastening to the base member, and has a fastening head for a dental prosthesis and an implant post which is introducible through the inside bore into the blind bore and connectable to the base member.

Abstract: An enossal single tooth implant for a fixed dental prosthesis includes an essentially cylindrical base member which is insertable into a bore introduced into a jaw bone and which has a blind bore open toward one coronal end to form a face edge, a spacer sleeve attached in an anti-twist fashion to the face edge of the member, an implant post directly or indirectly introduced into the blind bore of the base member and at least partially penetrating the spacer sleeve. The spacer sleeve has a circumferential surface which forms part of a fastening head for the dental prosthesis and has an annular joining shoulder for engaging an edge of the prosthesis that has a peripherally varying spacing from the face edge of the base member to allow for adaptation to the anatomical conditions.

Abstract: Supporting grid for the mechanical support of a cover membrane, which membrane covers a bone void filled with a bone replacement material such as hydroxyl apatite granules, particularly a recess in the proper bone tissue of the body, characterized in that the supporting grid is bendable around at least one axis predetermined by the fashioning of the supporting grid.

Abstract: 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.

Abstract: An implant has an implant member which is implantable in a bone material and has an axial threaded bore at one end which receives a threaded element which may be an implant post, an implant extension or a post for attachment by means of a screw connection. The threaded element has a head with a diameter greater than an outer diameter of the implant member adjacent the one end and the head has a pressing surface extending substantially at right angles to the axis of the implant member and beyond the outer diameter of the implant member. The head also has a circular recess between the pressing surface and the outer threads of the threaded element, which recess will receive an edge of the one end of the implant member when the threaded element is received in the threaded bore to prevent body tissue from growing into any slit or crevice between the implant member and the threaded element.

Abstract: The invention relates to a member provided with an external screw thread, which at least in the end portion of the screw thread is provided with at least one plastic part for at least partially covering the same and/or at least partially replacing the same.

Abstract: Screw unit with a closing screw having a screw head for the aseptic closing of an internal thread of a member and an introduction post in firm, but detachable connection on the closing screw.The detachable connection is formed by a tongue in an end of the post being received in a slot in the screw head which slot terminates inward of a peripheral edge of the screw head.

Abstract: An enossal single tooth implant is constructed of a base member having a eaded axial bore for receiving a threaded base element, which has a head for clamping a spacer ring on the end of the base member characterized by the ring member and base body having coacting interlocking members, such as recesses and tongues to form an arrangement to prevent relative twisting of the ring member on the base body. The ring member can also be provided with interlocking elements that will coact with a tooth replacement to prevent twisting of the tooth replacement provided on the ring member, which replacement is held by a post which is received in a threaded bore of the base element.

Abstract: An enossal implant for firmly seating a tooth replacement includes a fastng head on a metal implant post which is threadably secured into a base element, which is either a base body or a metal spacer threaded into the base body. To prevent twisting between the post and the base element, the base element has a recess for receiving an intermediate retaining ring formed of a plastic material which has smooth faces, and the ring is entrapped between a shoulder in the base element and a shoulder on the implant post and interlocking depressions are formed in either the recess and/or the shoulder of the post so that during threading-in of the post, the retaining ring is deformed to fill the recesses to restrain twisting therebetween.

Abstract: A plug connection for the detachable fitting of a prosthesis structure such as a tooth on a tooth peg or post characterized by a plug part provided on the post having a cylindrical base with a tip having a portion of a larger diameter than the base and having a circumferential conical surface extending to a tip, a socket part having a cavity for receiving the plug part and containing a clamping ring for engaging the shoulder formed at the portion and base and supporting a bearing ring in the cavity of an elastic plastic material for relieving impact stresses occurring substantially in a direction of a longitudinal axis of symmetry of the post.

Abstract: An enossal or endosteal implant with a fastening head and fastening arrannt having a metal implant post screwable into a basic structure for snugly fitting a conditionally removable denture with a spacer element provided with a centering collar being inserted into the open end of the basic structure and engageable with a shoulder of an upper edge of the basic structure and an intermediate element having a portion made of an elastic material is characterized by the spacer element being made of metal and having a closed end remote from the fastening head for the denture and being threaded into the basic structure; the intermediate element is insertable in a socket formed by a counterbore at the open end of the spacer element and is provided with a ring shoulder for engaging an upper edge of the spacer element, and the intermediate element has an inner bore whose diameter, in an area facing the fastening head for the denture and remote from the spacer sleeve, is larger than the external diameter of the implant p

Abstract: 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.

Abstract: A device for separating fine particles of solid matter from waste fluid has a water ring pump (16, 44), an air separator (18, 60) and a solid bowl centrifuge (24, 30) which are arranged axially one behind the other in the aforementioned sequence and are driven by the motor shaft (28) of a common drive motor (12).
