Methods and systems are provided repositioning teeth of a patient, which employ at least one appliance specific to the patient for placement in the patient's mouth during use. The at least one appliance includes a polymeric shell having a cavity shaped to receive teeth of the upper jaw of the patient. The polymeric shell is integral to a polymeric segment shaped to cover the hard palate of the upper jaw of the patient. The geometry and material properties of the shell is configured such that the appliance adjusts position of the teeth of the upper jaw of the patient during use. The geometry and material properties of the segment is configured such that the appliance adjusts position of the hard palate of the upper jaw of the patient during use. Additionally or alternatively, one or more appliances can be configured to contact the teeth of the lower jaw and a mandibular bone portion disposed below the gingiva of the teeth of lower jaw and adjust position of the teeth and the mandibular bone portion of the lower jaw of the patient during use.

Dental appliances, materials, and methods of forming such appliances and materials for improved laser marking are provided herein including the use of textured and/or roughened surfaces to enhance laser marking.

Systems and methods for planning a treatment for a patient’s teeth are provided. In some embodiments, a method includes receiving input data representing an initial tooth arrangement of a patient’s teeth. The method can include determining a target tooth arrangement for the patient’s teeth, the target tooth arrangement including a change in mass of at least one tooth. The method can also include generating a plurality of intermediate tooth arrangements configured to adjust the patient’s teeth from the initial tooth arrangement toward the target tooth arrangement. The method can further include generating instructions to output a visualization showing a difference in tooth mass between at least one intermediate tooth arrangement of the plurality of intermediate tooth arrangements and the target tooth arrangement.

Systems, methods, and devices for improved orthodontic treatment of a patient's teeth are provided herein. In some embodiments, a method includes determining an appliance geometry for a dental appliance. The appliance geometry can include a first region representing a shell comprising a plurality of teeth receiving cavities, and a second region representing at least one integrally formed component to be integrally joined to the shell. The method can also include generating instructions including a first digital representation of the shell based on the first region, and a second digital representation of the at least one integrally formed component based on the second region. The method can further include transmitting the instructions to a fabrication system configured to additively manufacture the dental appliance by fabricating the shell based on the first digital representation, concurrently with fabricating the at least one integrally formed component based on the second digital representation.

A system includes a partial enclosure configured to hold resin. The system further includes one or more structures configured to at least partially cover the resin. The one or more structures are configured to prevent evaporation of the resin. The system further includes a build platform configured to support an object that is being formed from layers of the resin. A first blade is configured to provide the layers of the resin to form the object on the build platform.

An orthodontic device is provided, including an anchorage structure, a palatal expansion structure, and at least one protrusion. The anchorage structure includes left and right posterior teeth caps configured to be removably worn on the posterior teeth of the maxillary dental arch; a palatal bar connecting the left and right posterior teeth caps; and an expanded arch extending from the left posterior teeth cap to the right posterior teeth cap. The palatal expansion structure includes: left and right anterior teeth parts configured to be removably worn on the anterior teeth of the maxillary dental arch; and expansion screws connecting the left anterior teeth part and the right anterior teeth part to each other and to the palatal bar. The at least one protrusion is formed on then occlusal side of the expanded arch and configured to contact the patient's mandibular dental arch when the orthodontic device is worn.
