ABSTRACT:
The dental sleeve has a cylindrical or a cylindrical and conical shape having a height and circumference corresponding to that of the tooth stump or model to be enclosed. In terms of material, it is a composite foil which includes at least two layers and in which the inner layer, and optionally also the outer layer, consists of fine gold or a gold alloy, while the other layer or layers consist of platinum, palladium, silver, indium or iridium or of alloys of such metals or of alloys of such metals and gold. The cylindrical shape is produced by spot-welding the inner gold layer on the two narrow sides of the foil with a special welding technique. The dental sleeve is used as a carrier for a composite ceramic crown.
