Dental appliance with cavity for an unerupted or erupting tooth

A method for accommodating an unerupted or erupting tooth during at least a portion of a treatment plan, comprising:

• predicting at least one of a size, shape, location, and orientation of an unerupted or erupting tooth;
• determining a scaling factor for a first projected dimension of a cavity for accommodating the unerupted or erupting tooth as the tooth erupts;
• and
• creating a vitual shell on a computing device having a plurality of cavities to receive teeth of a jaw, wherein at least one of the plurality of cavities created is the cavity for accommodating the unerupted or erupting tooth.

A non-transitory computing device readable medium having instructions stored thereon that are executable by a processor to cause a computing device to:

• identify, via a computing device, whether a patient's arch contains an unerupted or erupting tooth;
• obtain dimensional tooth data for at least on dimension of at least one tooth based on one or more tooth eruption prediction factors;
• determine a first projected dimension for the unerupted or erupting tooth based on the dimensional tooth data;
• determine a scaling factor for the first projected dimension of a cavity of a dental appliance positioned to accommodate the unerupted or erupting tooth as the tooth erupts;
• and
• create the dental appliance configured to reposition at least one tooth of the patient based on the one or more tooth eruption prediction factors and the dimensional tooth data, wherein the dental appliance includes the cavity sized according to the determined scaled first projected dimension for the unerupted or erupting tooth.
