Problems solved by technology

The design of such a restoration will result in the restoration not being able to be inserted into the mock-up of the patient's tooth-set when the mock-up of the patient's tooth-set is manufactured from a material that is not easily displaced / deformed by the dental technician

Embodiment Construction

[0219] In the following description, reference is made to the accompanying drawings, which show by way of illustration only how the invention may be practiced.

[0220] exist figure 1 , 2, 3, 5 and 7. Illustrative examples of abutments for dental implants used as dental restorations. The restoration can obviously also consist of or comprise other parts, for example crowns, bridges, removable dentures or dentures.

[0221] figure 1 A schematic diagram showing the conflict of the volumes of the virtual model of the restoration and the gingival part of the virtual model of the tooth set.

[0222] In procedures related to dental implants and corresponding dental restorations, such as the abutments shown, dental technicians often position the implant simulant in the gingival portion of the mockup when making the mockup of the set of teeth. In some cases, the restoration interferes with the gingival portion of the mock-up of the tooth set such that the restoration cannot be inser...

Abstract

The present invention provides a method of generating and modifying a virtual model of a tooth set, wherein the method enables the insertion of a restoration into a physical model of the tooth set manufactured from the virtual model of the tooth set.

Description

technical field [0001] The present invention generally relates to a method and system for generating a virtual model of a set of teeth in order to manufacture a physical model of the set of teeth, and to a solid model of the set of teeth. [0002] The invention may be used, for example, in dental implants and other applications where a restoration is to be inserted into the gingival portion of a mock-up of a set of teeth. Background technique [0003] When designing a patient's dental restoration, dental technicians often use a solid model of the patient's set of teeth. In many cases it is preferred to design the restoration, eg the abutment and the corresponding crown or bridge, to be shaped such that it displaces gently a part of the patient's gingiva. The design of such a restoration will result in the restoration not being able to be inserted into the mock-up of the patient's set of teeth when the mock-up of the patient's set of teeth is manufactured from a material tha...
