Abstract
Systems and methods for improved visual prosthetic and orthodontic treatment planning are provided herein. In some aspects, a method for preparing a tooth of a patient is disclosed. The method may comprise building a model of a dentition of the patient including a model of the initial shape of tooth. The method may also include determining a final prepared shape of the tooth. In some aspects, the method may also include generating a treatment plan comprising a plurality of steps to modify the initial shape of the tooth to the final prepared shape of the tooth. The method may also include rendering visualizations for the plurality of steps of the treatment plan. The visualizations may depict the removal of tooth material to modify the initial shape of the tooth to the final prepared shape of the tooth.
Claims36
A method for orthodontic treatment, the method comprising:
- receiving a three-dimensional composite model of an initial shape of a plurality of teeth comprising a plurality of voxels, wherein the three-dimensional composite model is based on a three-dimensional surface model from a three-dimensional surface scan of a patient's dentition and a volumetric model from a scan of an internal structure of the patient's dentition;
- and
- wherein a voxel of the plurality of voxels comprises a defect type;
- generating a treatment plan comprising a plurality of steps to modify the plurality of teeth and one or more orthodontic movement steps comprising movement and/or rotation of one or more teeth;
- identifying a modification of a shape of a tooth of the plurality of teeth from an initial shape of the tooth to a final shape of the tooth;
- and
- rendering a visualization for one or more steps of the plurality of steps of the treatment plan, the visualization indicating tooth material to be removed to modify the initial shape of the tooth to the final shape of the tooth.
A method for orthodontic treatment, the method comprising:
- receiving a model of a dentition of a patient comprising a model of an initial shape of a plurality of teeth;
- generating a treatment plan comprising a plurality of steps to modify the plurality of teeth and one or more orthodontic movement steps comprising movement and/or rotation of one or more teeth;
- identifying a modification of a shape of a tooth of the plurality of teeth from an initial shape of the tooth to a final shape of the tooth;
- rendering a visualization for one or more steps of the plurality of steps of the treatment plan, the visualization indicating tooth material to be removed to modify the initial shape of the tooth to the final shape of the tooth;
- receiving an updated dentition model after removal of a portion of material according to a step of the treatment plan, the updated dentition model comprising an updated model shape of the patient's tooth;
- comparing the updated dentition model with a dentition model for the step of the treatment plan;
- and
- indicating remaining material that should be removed according to the step of the treatment plan.
A system for aiding in orthodontic treatment, the system comprising:
- one or more processors and memory, wherein the memory comprises instructions executable by the one or more processors to cause the system to:
- receive a three-dimensional composite model of an initial shape of a plurality of teeth comprising a plurality of voxels, wherein the three-dimensional composite model is based on a three-dimensional surface model from a three-dimensional surface scan of a patient's dentition and a volumetric model from a scan of an internal structure of the patient's dentition;
- and wherein a voxel of the plurality of voxels comprises a defect type;
- generate a treatment plan comprising a plurality of steps to modify the plurality of teeth and one or more orthodontic movement steps comprising movement and/or rotation of one or more teeth;
- identify a modification of a shape of a tooth of the plurality of teeth from an initial shape of the tooth to a final shape of the tooth;
- and
- render a visualization for one or more steps of the plurality of steps of the treatment plan, the visualization indicating tooth material to be removed to modify the initial shape of the tooth to the final shape of the tooth.

- receive an updated dentition model after removal of a portion of material according to a step of the treatment plan, the updated dentition model comprising an updated model shape of the patient's tooth;
- compare the updated dentition model with a dentition model for the step of the treatment plan;
- and
- indicate remaining material that should be removed according to the step of the treatment plan.
