Abstract

See full text

Systems, methods, and devices for producing appliances for expansion of the arch of a patient. Methods may include forming a shell from a prepolymer material, the shell including teeth receiving structures configured to receive at least a portion of the patient's teeth. The prepolymer material may be crosslinked to provide a first crosslinked polymer having a first degree of crosslinking. Methods may also include forming a force generating portion connected with the shell. The force generating portion may be configured to span a space between opposing posterior teeth of the patient and to apply an expansion force between the opposing posterior teeth of the patient. The force generating portion may be formed from the same prepolymer material as the shell. Forming the force generating portion may include varying crosslinking to provide a second crosslinked polymer having a second degree of crosslinking that is different than the first degree of crosslinking.
