Abstract

A method in the preparation of a dental restoration, in which the dental restoration has an implant unit and a head structure interconnectible with one another, comprises the steps of providing an auxiliary material, providing a computerized head receiving surface representation (A′), manufacturing from the auxiliary material a measuring element having a measuring surface (M) and an implant unit coupling surface (X). The measuring surface (M) is adapted such that it can be captured by an optical measuring device, and the measuring element coupling surface (X) is adapted for mating with the head receiving surface (A). The method may help making the preparation of a dental restoration more time and cost efficient.
