2. The method of claim 1, wherein the set of diagnostic data is indicative of at least one of:

(a) which teeth are present, (b) condition of the teeth, (c) position of the teeth in a respective dental arch, (d) relationship of at least one tooth to other teeth, (e) size of the teeth, or (f) alignment of the teeth.

3. The method of claim 1, wherein the first evaluation routine further comprises detecting whether there is conflicting data in the set of diagnostic data.

4. The method of claim 3, wherein the set of diagnostic data comprises data of the patient'"'"'s teeth from a plurality of views, and wherein the first evaluation routine comprises matching data of the patient'"'"'s teeth from a first view of the plurality of views to data of the patient'"'"'s teeth from a second view of the plurality of views.

5. The method of claim 3, further comprising generating feedback information if conflicting data is detected in the set of diagnostic data.

6. A computerized system for dental treatment planning, comprising:

a fabrication machine; and

one or more computers that include one or more processors and memory, including instructions executable by the one or more processors to cause the one or more computers to at least;

receive, by the one or more computers, a set of diagnostic data comprising one or more malocclusions and a current arrangement of a patient'"'"'s teeth;

execute, by the one or more computers, a first evaluation routine for the set of diagnostic data comprising validating the set of diagnostic data at least against one or more case selection criteria for a desired treatment system, wherein successful validation indicates that the patient'"'"'s teeth are acceptable for treatment using the desired treatment system;

after successful validation by the first evaluation routine, execute, by the one or more computers, a second evaluation routine that evaluates the distance the patient'"'"'s teeth move between the current arrangement and an initial desired arrangement against a magnitude of movement included in the one or more case selection criteria;

after successful evaluation by the second evaluation routine, generate, by the one or more computers, a treatment plan comprising data sets for moving the patient'"'"'s teeth from the current arrangement toward the initial desired arrangement of the patient'"'"'s teeth using the set of diagnostic data; and

output the data sets to the fabrication machine, the data sets being a shape of a plurality of appliances for treating the patient, wherein the data sets are configured to control a fabrication machine to produce the plurality of appliances for treating the patient according to the outputted data sets.

7. The system of claim 6, wherein the instructions further cause the one or more computers to:

generate a first set of questions relating to a treatment goal for the patient'"'"'s teeth;

receive, in response to the first set of questions, a set of treatment goal data relating to a desired arrangement of the patient'"'"'s teeth; and

execute a third evaluation routine for the set of treatment goal data comprising validating the set of treatment goal data against at least one of the sets of diagnostic data or one or more case selection criteria for the desired treatment system, thereby determining feasibility of the treatment goal.

8. The system of claim 7, wherein the first set of questions are generated based on the set of diagnostic data.

9. The system of claim 7, wherein the instructions further cause the one or more computers to:

generate a second set of questions relating to a desired treatment path for the patient'"'"'s teeth;

receive, in response to the second set of questions, a set of treatment path data relating to a desired treatment path for moving the patient'"'"'s teeth toward the desired arrangement; and

execute a fourth evaluation routine for the set of treatment path data comprising validating the set of treatment path data against at least one of the sets of diagnostic data, the set of treatment goal data, or the one or more case selection criteria for the desired treatment system, thereby determining feasibility of the desired treatment path.

10. The system of claim 6, wherein the set of diagnostic data is indicative of at least one of:

(a) which teeth are present, (b) condition of the teeth, (c) position of the teeth in a respective dental arch, (d) relationship of at least one tooth to other teeth, (e) size of the teeth, or (f) alignment of the teeth.

11. The system of claim 6, wherein the first evaluation routine further comprises detecting whether there is conflicting data in the sets of diagnostic data.

12. The system of claim 11, wherein the sets of diagnostic data comprise data of the patient'"'"'s teeth from a plurality of views, and wherein the first evaluation routine comprises matching data of the patient'"'"'s teeth from a first view of the plurality of views to data of the patient'"'"'s teeth from a second view of the plurality of views.

13. A computerized system for dental treatment planning, comprising:

a fabrication machine; and

one or more computers that include one or more processors and memory, including instructions executable by the one or more processors to cause the one or more computers to at least;

receive, by the one or more computers, a set of diagnostic data comprising one or more malocclusions and a current arrangement of a patient'"'"'s teeth;

execute, by the one or more computers, a first evaluation routine for the set of diagnostic data comprising validating the set of diagnostic data at least against one or more case selection criteria for a desired treatment system, wherein successful validation indicates that the patient'"'"'s teeth are acceptable for treatment using the desired treatment system;
