Direct 3D-printed orthodontic aligners with torque, rotation, and full control anchors

Direct 3D-printed orthodontic aligners with torque, rotation, and full-control anchors divots are provided. An example process generates multiple virtual models of orthodontic treatment based on progressive moduli of elasticity (MOE) of different materials that will be used to 3D-print a progressive set of 3D-printed aligners. A progression of 3D-printed aligners applies modeled forces to the divot anchors positioned by the models and to the teeth, in treatment stages that are also computed by the models. One class of the example 3D-printed aligners may have flat occlusal biting surfaces, enabling simultaneous treatment of bite correction, temporomandibular joint disorder (TMD), lower jaw growth, and sleep apnea, along with orthodontic movement of teeth. An example 3D-printed aligner has a micro blower for creating air pressure to treat apnea. The aligner may have a microprocessor, sensors, data handling, and data transmission, for controlling actions of the 3D-printed aligner.
