Abstract:
1. A method for producing an appliance for repositioning teeth, the method comprising: producing an activatable dental appliance comprising a shell having teeth receiving cavities shaped to receive and apply a resilient force to a patient's teeth, wherein producing the activatable dental appliance comprises forming a bump at a predetermined location in at least one of the teeth receiving cavities such that the bump is configured to deliver one or more forces to a tooth received in the at least one of the teeth receiving cavities, the bump being in a non-activated first state where the bump extends outward and away from the at least one of the teeth receiving cavities, and the bump further configured for inversion into an activated second state where the bump extends inward toward the at least one of the teeth receiving cavities so as to contact a received tooth, wherein the shape of the bump in the activated state is substantially the same as the shape of the bump in the non-activated state.
