Abstract: Systems and methods for planning a treatment for a patient's teeth are provided. In some embodiments, a method includes receiving a treatment plan including a target tooth arrangement including a change in mass of at least one tooth. The method can also include outputting a graphical user interface including a visualization of the treatment plan. The visualization can include a plurality of digital models, each digital model representing an intermediate tooth arrangement configured to adjust the patient's teeth toward the target tooth arrangement. The visualization can also include a heatmap overlaid onto at least one digital model of the plurality of digital models. The heatmap can show a difference in tooth mass between the target tooth arrangement and the corresponding at least one intermediate tooth arrangement of the at least one digital model.

Abstract: Network enabled 3D printing and automated processing techniques for oral devices are disclosed herein. An example technique includes receiving, via a network (120), a data file representative of a mouth of a user, and printing, by a 3D printer (112), a 3D oral device based on the data file. The example technique may further include automatically ejecting, from the 3D printer, the 3D oral device, and scanning, by a scanner (114), the 3D oral device to generate a 3D scan file of the 3D oral device. The example technique may further include comparing the 3D scan file with the data file to determine at least one feature represented in the 3D scan file that exceeds a deviation threshold relative to a corresponding respective feature represented in the data file; and finishing, by a finishing module (116), the 3D oral device by smoothing the at least one feature on the 3D oral device.

Abstract: Processes and devices for dental restorations employ molding tools that isolate individual tooth surfaces onto which dental composite material is to be applied and cured into individual cavities to prevent bonding of adjacent teeth. The processes and tools utilize matrix separators between teeth and a molding tool having matrix guide pockets that receive edges of the matrix separators to define the individual cavities.
