Abstract
A support for sustaining and/or forming a dental prosthesis, comprises an axle, an anchoring part which can be anchored in a bone or a master model, and a head part which protrudes out of said bone or master mode. The head part has intermediate spaces distributed around the axis, i.e., several first intermediate spaces forming a divided circle, and a second, wider and/or deeper intermediate space. A cap can be fixed to the support. The cap has at least one projecting part for engaging in an intermediate space and, optionally, can be configured for fixing in several different rotational positions or a single rotational position, the support allowing exact positioning. The cap can also be produced without a projecting part of the type mentioned. The same support can be used to form different types of dental prostheses.
