## Abstract

A method for treating an orthodontic condition can include receiving patient data, such as through a website, accessing a database having information derived from patient treatments, generating a model of an orthodontic condition defining one or more anatomic features of a set of teeth, identifying a diagnosis of an orthodontic condition and identifying a treatment regimen for the diagnosis. A method can include tagging an anatomic feature with an electronic identifier and automatically generating a tooth setup. A system can include a server and a database, which can include information relating to patient treatments, and a website for receiving patient data. A system can include an electronic model representing anatomic features of a patient's teeth and an application adapted to identify a diagnosis and a treatment regimen for an orthodontic condition, which can include executing artificial intelligence and/or other algorithms.

## Claims

### Claim 1

A method for delivering a diagnosis and identification of a treatment for an orthodontic condition, comprising:
providing a graphical user interface that prompts a user for electronic patient data regarding the orthodontic condition;
providing access, through the graphical user interface, to a database that comprises or has access to information derived from patient treatments, the information derived from patient treatments including an electronically stored data set for each patient treatment, wherein each data set includes data that represents at least one of (a) a location and position of one or more teeth subject of a corresponding patient treatment and (b) a previously diagnosed orthodontic condition for the corresponding patient treatment;
comparing coordinates that represent at least two anatomic features of a set of teeth to at least a portion of the information derived from patient treatments accessible via the database;
identifying a best fit data set that represents a statistical or prioritized best fit for the coordinates;
identifying at least one diagnosis of the orthodontic condition by prioritizing at least a portion of the data from a plurality of the data sets; and
delivering an electronic treatment model of the orthodontic condition that provides to the user one or more of (a) a diagnosis, (b) the diagnosis along with a probability value representing a likelihood the diagnosis is accurate, and (c) a plurality of diagnoses along with a plurality of probability values.

### Claim 2 (depends on 1)

The method of claim 1, wherein each of the plurality of probability values represents a likelihood that a corresponding one of the plurality of diagnoses is accurate.

### Claim 3 (depends on 1)

The method of claim 1, further comprising identifying at least one treatment regimen for the at least one diagnosis by prioritizing at least a portion of the data from a plurality of the data sets, and delivering an electronic treatment model of the orthodontic condition that provides to the user one or more of (a) a treatment regimen, (b) the treatment regimen along with a probability value representing a likelihood the treatment regimen is accurate, and (c) a plurality of treatment regimens along with a plurality of probability values.

### Claim 4 (depends on 3)

The method of claim 3, wherein each of the plurality of probability values represents a likelihood that a corresponding one of the plurality of treatment regimens is accurate.

### Claim 5 (depends on 3)

The method of claim 3, wherein the at least one treatment regimen for the at least one diagnosis includes at least one of a treatment approach, a corrective appliance and a combination thereof.

### Claim 6 (depends on 3)

The method of claim 3, further comprising outputting to the user a plurality of treatment regimens along with a plurality of probability values, wherein each of the plurality of probability values represents a relative likelihood that a corresponding one of the potential treatment regimens will be effective to reorient one or more teeth of the set of teeth represented in the electronic treatment model, and wherein the plurality of treatment regimens include at least one of interproximal tooth reduction, tooth extraction, tooth restoration and a combination thereof.

### Claim 7 (depends on 3)

The method of claim 3, wherein the information derived from patient treatments includes data representing treatment time for one or more patient treatments and the method further comprises outputting to the user at least one of an estimated treatment time and an average treatment time for the at least one treatment regimen.

### Claim 8 (depends on 3)

The method of claim 3, wherein at least one of the at least one diagnosis and the at least one treatment regimen is the same as that for a patient treatment corresponding to the best fit data set.

### Claim 9 (depends on 1)
