Methods for interproximal reduction using 3d scanner

A system for performing an inter-proximal reduction procedure, the system comprising:

• an intra-oral scanning system configured to obtain imaging of a first tooth of a patient;
• a display screen configured to display imaging from the intra-oral scanning system;
• and
• a controller comprising a non-transitory computer-readable storage medium having instructions stored therein for causing the system to perform the following steps:
• receive a treatment plan including a specification for performing an interproximal reduction procedure on a first tooth;
• receive imaging from the intra-oral scanning system, the imaging representing at least a portion of the first tooth after removal of tooth matter during the inter-proximal reduction procedure;
• compare the imaging to the specification to determine conformance of the first tooth to the treatment plan;
• and
• generate guidance data based on compared imaging, wherein the guidance data indicates an amount of additional tooth matter to be removed to conform the first tooth to the specification.
