摘要： 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.
