Problems solved by technology

Each tooth is individually removable from the artificial gingiva, and although the visible crown of each tooth varies according to normal anatomy, the pegs are the same for each tooth, so there is no need to provide students with the correct position for each tooth instructions

Embodiment Construction

[0282] In the following description, reference is made to the accompanying drawings, which show by way of example how the invention may be practiced.

[0283] figure 1 An example of a flowchart of one embodiment of the method is shown.

[0284]A virtual model of the tooth group is generated in step 101 and is based on a virtual representation of the tooth group. The virtual representation may be provided by scanning an impression of the set of teeth or directly scanning the set of teeth in the patient's mouth using an intraoral scanner. A virtual model may include one or more teeth. The virtual model may have been previously generated and the invention is not limited to methods involving generating the virtual model.

[0285] Each of the teeth is configured in step 102 to be placed in the model as a removable part, and each removable part is adapted to fit into a corresponding cavity in the gingival portion of the model.

[0286] Means for supporting and positioning each o...

Abstract

Disclosed is a computer-implemented method of generating a virtual model of a set of teeth for manufacturing a physical model of the set of teeth, the method comprising: - providing a virtual model of the set of teeth (402), the model comprising a gingival part (401) and a tooth configured to be part of a removable component (405) in the model; - generating a cavity (407) in said gingival part, said cavity comprising a cavity wall, into which cavity said removable component fits such that an interface between the removable component (405) and the wall of the cavity (407) is defined, where the removable component (405) and the cavity (407) are configured to provide a gap at said interface; and - providing means (409) for supporting and positioning the removable component (405) in the cavity (407), where the means for supporting and postitioning are generated on one of said removable component and said cavity wall such that the means (409) for supporting and positioning extends across said gap between said removable component (405) and said cavity wall; - wherein the area of contact between the removable component (405) and the cavity wall at said interface is controlled by the shape of the adjoining surfaces of the means (409) for supporting and positioning and the other of the removable component (405) and the cavity wall.

Description

technical field [0001] The present invention generally relates to a computer-implemented method and system for generating a virtual model of a set of teeth for use in manufacturing a physical model of the set of teeth, and to a physical model of the set of teeth. Background technique [0002] When a patient needs a dental restoration such as a crown, bridge, abutment, or implant, the dentist will prepare the tooth, such as grinding down the damaged tooth to create a preparation to which the crown can be glued. An alternative treatment is to insert an implant, such as a titanium screw, into the patient's jaw and fit a crown or bridge over the implant. After preparing teeth or inserting implants, the dentist can make impressions of the maxilla, mandible and occlusal registration or a single impression in a double-sided tray (also called a triple tray). [0003] The impression is sent to the dental technician who will make the restoration. The first step in fabricating a rest...
