Abstract

A method includes to receive, via a computing device, data representing a plurality of teeth, identify data indicating which of the plurality of teeth are unerupted or erupting, predict at least one characteristic of a tooth of the unerupted or erupting teeth after they have fully erupted using one or more tooth eruption prediction factors, generate new data representing the unerupted or erupting teeth in multiple states of eruption based upon the predicted at least one characteristic of the fully erupted teeth, and generate a series of incremental tooth arrangements with the new data to define a proposed orthodontic treatment based on the new data representing the unerupted or erupting teeth in multiple states of eruption.

Claims (9)

1. A dental appliance system, comprising:

a first appliance of a series of appliances designed to incrementally implement a treatment plan, comprising a first shell having a plurality of cavities therein designed to receive teeth of a jaw in a first stage of the treatment plan with at least one of the plurality of cavities being a cavity configured to accommodate virtual maximum dimensions, in three dimensions above the gingival line, of an unerupted or erupting tooth therein; and

a second appliance of the series of appliances, comprising a second shell having a plurality of cavities therein designed to receive teeth of the jaw in a second stage of the treatment plan the second shell having a cavity that corresponds with the cavity configured to accommodate virtual maximum dimensions of an unerupted or erupting tooth of the first shell and wherein the virtual maximum dimensions are calculated by taking the maximum dimensions of two or more virtual tooth geometry data sets of the same type of tooth.

2. The system of claim 1 , wherein the cavities configured to accommodate the virtual maximum dimensions of an unerupted or erupting tooth include a gingival edge and wherein the gingival edge is oriented and shaped based upon a prediction of the orientation and shape of the gingiva that will be adjacent to the gingival edge according to each shell's respective treatment stage.

3. The system of claim 1 , wherein the cavities configured to accommodate the virtual maximum dimensions of an unerupted or erupting tooth each differ in at least one of: size, shape, location, or orientation.

4. The system of claim 1 , wherein the cavities configured to accommodate the virtual maximum dimensions of an unerupted or erupting tooth have at least one characteristic of: size, shape, location, or orientation based on data representing the unerupted or erupting teeth in multiple states of eruption that is based upon one or more tooth eruption prediction factors of at least one fully erupted tooth of a patient.

5. The system of claim 1 , wherein the cavities configured to accommodate the virtual maximum dimensions of an unerupted or erupting tooth have at least one characteristic of: size, shape, location, or orientation based on data including at least one of: a size, shape, location, and orientation of a tooth adjacent to the unerupted or erupting tooth.

6. The system of claim 1 , wherein the cavities configured to accommodate the virtual maximum dimensions of an unerupted or erupting tooth have at least one characteristic of: size, shape, location, or orientation based on data including at least one of: a size, shape, location, and orientation of an opposing tooth to the unerupted or erupting tooth.

7. The system of claim 1 , wherein the cavities configured to accommodate the virtual maximum dimensions of an unerupted or erupting tooth have at least one characteristic of: size, shape, location, or orientation based on data including at least one of: a size, shape, location, and orientation of a tooth that is the same type of tooth to the unerupted or erupting tooth.
