Abstract
Systems and methods are provided for preparation of orthodontics and prosthodontics. A method may include scanning a patient's teeth to form first 3D data of the patient's teeth including a removable element that obscures part of the dental surfaces of the patient's teeth and non-obscured tooth surfaces, removing the removable element form the patient's teeth so that the removable element no longer obscures the part of the dental surfaces of the patient's teeth, and scanning the previously obscured part of the dental surfaces of the patent's teeth and the non-obscured tooth surfaces.
Claims30
A dental system for intraorally scanning a patient's teeth for a dental procedure, the dental system comprising:
- a hand-held intraoral scanner;
- and
- a computer readable medium including instructions that when executed by a computer system, causes the computer system to:
- receive first 3D intraoral scan data of the patient's teeth from the hand-held intraoral scanner;
- display, to a display, a first 3D surface model of the patient's teeth, wherein the first 3D surface model of the patient's teeth is based on the received first 3D intraoral scan data of the patient's teeth;
- receive user input defining a surface portion of the first 3D surface model to be removed;
- after receiving the user input, remove, from the displayed first 3D surface model, the surface portion of the first 3D surface model to be removed according to the user input;
- after removing the surface portion of the first 3D surface model, receive second 3D intraoral scan data of the patient's teeth from the hand-held intraoral scanner;
- replace at least a portion of the removed surface portion of the first 3D surface model with at least a surface portion of a second 3D surface model based on the received second 3D intraoral scan data of the patient's teeth to produce a composite 3D surface model of the patient's teeth that is based on the first 3D intraoral scan data and the second 3D intraoral scan data;
- and
- output, to the display, the composite 3D surface model of the patient's teeth.

- and
- output, to the display, the composite 3D surface model of the patient's teeth.

- receive user input via the displayed first 3D surface model at least defining a surface portion of the first 3D surface model to be retained;
- after receiving the user input, receive second 3D intraoral scan data of the patient's teeth from the hand-held intraoral scanner;
- replacing at least a portion of the first 3D surface model not to be retained according to the user input with at least a surface portion of a second 3D surface model based on the received second 3D intraoral scan data of the patient's teeth to produce a composite 3D surface model of the patient's teeth that is based on the first 3D intraoral scan data and the second 3D intraoral scan data;
- and
- output, to the display, the composite 3D surface model of the patient's teeth.
