design for a fixed and a ausnehmbaren prosthesis between two healthy or restored pfeilerelementen

摘要

The present invention relates to methods of producing a fixed or removable tooth prosthesis comprising a single element or multiple elements in the region of the frontal and lateral teeth between two pillar elements which are left as intact as possible. It is not absolutely necessary for the pillar elements to be free of restorations at the point of attachment of the structure. For the structure, an individually cast plate of a metal of choice (1) provided with an opening of defined dimensions at the approximal side at the level of the contact point of the pillar is fastened on the particular pillar by means of the etch-bonding technique. Thereupon, an oval adapter piece (3) (17) having a wedge-shaped or undercutting loop-shaped incision in its top side and a tapering opening in the middle is provided with a screw thread and cast on, welded on or cemented. A moveable-cut metal pin (8) is guided through the coinciding openings of the oval adapter piece and the plate and cemented in the small channel prepared in the pillar element (20). The pin is secured from the outside with a securing screw (12) which is tightened with a screwing instrument in the appropriate depression (15) in the top side of the screw. At the same time, the hemispherical base (13) of the securing screw fits in the concave surface (11) of the countersunk pin head. IMAGE
