Claim 10:
11. A method for fabricating an orthodontic appliance configured to reposition a patient's teeth, the method comprising:
providing a polymerizable composition, the polymerizable composition including a first polymerizable component and a second polymerizable component, the polymerizable composition characterized by an initial ratio of the first polymerizable component to the second polymerizable component; and
fabricating a portion of the orthodontic appliance by applying radiation to the polymerizable composition, wherein the portion of the orthodontic appliance comprises:
a first region including a first ratio of the first polymerizable component to the second polymerizable component, the first ratio being different from the initial ratio, and
a second region including a second ratio of the first polymerizable component to the second polymerizable component, the second ratio being different from the initial ratio and the first ratio.
