    Abstract: Disclosed is a method for planning, visualizing, and/or optimizing dental restoration on at least a part of the pre-prepared teeth of a patient, wherein said method comprises the steps of:
    - providing at least one 3D digital model of at least a part of the pre-prepared teeth;
    - designing at least one dental restoration CAD model based on the 3D digital model of at least a part of the pre-prepared teeth;
    - providing at least one 3D digital model of at least a part of the prepared teeth, where the prepared teeth are provided by preparing the pre-prepared teeth by dental restorative work, at least partly based on the dental restoration CAD model; and
    - aligning the 3D models of the pre-prepared and the prepared teeth.

    Abstract: Method for designing a partial removable denture for a patient comprising the steps of:
    - providing a 3D scan of the patient's teeth;
    - virtually designing a framework;
    - virtually designing at least one telescopic double crown,
    wherein the at least one telescopic double crown comprises an internal crown which is defined as a primary part, and an external crown which is defined as a secondary removable part, and wherein virtually designing the at least one telescopic double crown further comprises the steps of:
    - virtually designing the primary part;
    - virtually designing the secondary part; and
    - automatically generating the external surface of the primary part and the internal surface of the secondary part to have matching shapes,
    where at least a region of the external surface of the primary part and the corresponding region of the internal surface of the secondary part are substantially straight having the same well-defined angle.

    Abstract: System and computer-implemented method of designing and/or manufacturing a post and core to match a bore of a tooth, said method comprising the steps of: a) obtaining at least one impression of a set of teeth comprising a bore; b) scanning the impression of the set of teeth comprising the bore; c) providing a three-dimensional scan representation of the impression comprising the bore; d) transforming the three-dimensional scan representation to a three-dimensional positive working model of the set of teeth and the bore; and e) designing a post and core model from the positive working model of the bore. The invention relates in particular to CAD/CAM design and/or manufacture of post and core.

    Abstract: The present invention provides a method for computer-controlled creation of non-occluding earpieces with tube bore. The non-occluding earpieces are created based on a three-dimensional computer model of at least part of the outer ear and at least part of the auditory canal. The said model is created by a laser scanner, in the ear scanner or by other means. The said three-dimensional computer model is virtually modified to create the non-occluding earpieces and the tube bore. Finally the physical non-occluding earpieces are manufactured using rapid prototyping equipment.
