Abstract
In a shell for adapting a retention element to an anchoring element, and a method of forming a further retention element on an anchoring element including a shell, the shell has an internal cavity, the dimensions of which are matched to the external dimensions of the retention element and which is connectable to the retention element in an integral or form-fitting manner, and has an outer surface which is formed as a further retention element.
Claims15
An assembly comprising:
- an anchoring element comprising a first retention element having outside dimensions and being a worn ball head located on a neck or a non-worn ball head located on a neck;
- and
- a shell configured for adaptation of the first retention element on the anchoring element;
- wherein the shell has a ball-shaped body and an interior cavity in the ball-shaped body and a circumferential extension, the interior cavity having cavity dimensions adapted to the outside dimensions of the first retention element, the interior cavity having an undercut that is adapted to surround a lower base of the worn ball head or the non-worn ball head and to hold the shell on the first retention element or is adapted to surround a lower base of the worn ball head or the non-worn ball head and to support retention on the first retention element, the circumferential extension surrounding the neck;
- wherein the interior cavity is connected with the first retention element with a material fit or a shape fit;
- wherein the shell has a ball-shaped outer surface configured as a second retention element which is a patrix;
- wherein an adhesive material is located between an inner surface of the interior cavity and a surface of the retention element;
- and
- wherein the extension is made of a material that is different from and more elastic than the ball-shaped body.

A method of using a shell, comprising the steps:
- selecting a shell while paying attention to outside dimensions of a first retention element;
- setting the shell onto the first retention element;
- and
- setting a dental prosthesis onto the shell;
- wherein the shell is configured for adaption of the first retention element on an anchoring element, the anchoring element being a worn ball head located on a neck or a non-worn ball head located on a neck;
- wherein the shell has a ball-shaped body and an interior cavity in the ball-shaped body and a circumferential extension, the interior cavity having cavity dimensions adapted to the outside dimensions of the first retention element, the interior cavity having an undercut that is adapted to surround a lower base of the worn ball head or the non-worn ball head and to hold the shell on the first retention element or is adapted to surround a lower base of the worn ball head or the non-worn ball head and to support retention on the first retention element, the circumferential extension surrounding the neck;
- wherein the interior cavity is connected with the first retention element with a material fit or a shape fit;
- wherein the shell has a ball-shaped outer surface configured as a second retention element which is a patrix;
- wherein an adhesive material is located between an inner surface of the interior cavity and a surface of the retention element;
- and
- wherein the extension is made of a material that is different from and more elastic than the ball-shaped body.
