The authors describe a computer-controlled system that can partially automate the fabrication of maxillary orthodontic appliances. The system can be programmed to deposit and cure the acrylic portion of these appliances. Using this new process, the operator places the orthodontic wires and expansion screws on the surface of the dental cast, secures the cast onto the machine and describes the desired shape of the appliance via graphical user interface. The machine then applies and cures the acrylic to form the finished appliance. Only minimal grinding and buffing is required.
