Abstract: A method of making a physical object by additive manufacturing. In the method a hardenable primary material is provided, the object is built up by successively hardening layers of the hardenable primary material, and the object is cleaned from excess material by moving the object and thereby generating a mass inertial force in the excess material. The invention facilitates the making of objects by additive manufacturing.

Abstract: A method of making a dental restoration has the steps of: determining a virtual space available for accommodation of a dental restoration for a tooth to be restored; retrieving a predefined virtual master dental restoration surface from a database; fitting the virtual master dental restoration surface in the space to provide a virtual outer dental restoration surface; creating a virtual inner dental restoration surface independent of a shape of the tooth to be restored; providing a virtual model of a dental restoration based on a combination of the virtual outer dental restoration surface and the virtual inner dental restoration surface; and fabricating the dental restoration based on the dental restoration model.

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.

Abstract: A method for designing a dental restoration of a type comprising a dental implant, a dental super structure, and a dental abutment for connecting the implant and the super structure. The method comprises the steps of retrieving a predetermined computer model of an abutment, using a user-created computer representation of a surface of the dental implant for providing a computer representation of an implant receiving surface, and for providing the predetermined abutment model with the implant receiving surface representation to provide a user-adapted abutment model. The method may help minimizing the time and costs in the preparation of a dental restoration.
