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.
Claims20
A system for accounting for changes in surface topology when scanning a patient's teeth for a dental procedure, the system comprising:
- a hand-held intraoral scanner;
- and
- a computer system operatively connected to the hand-held intraoral scanner and comprising instructions that, when executed by the computer system, causes the computer system to:
- receive, at a first time, initial scan data of a first surface portion of tissue and a second surface portion of tissue from the hand-held intraoral scanner, the first surface portion of tissue having a first surface topology;
- display a first model of tissue of the patient, wherein the first model of tissue of the patient is based on the initial scan data of the patient's teeth and comprises surface data representative of the first surface portion of tissue and the second surface portion of tissue;
- receive user input, via the displayed first model, demarcating the surface data representative of the first surface portion of tissue and the surface data representative of the second surface portion of tissue;
- receive, at a second time, after the first time, rescan data from the hand-held intraoral scanner of an intraoral cavity of the patient, the rescan data including surface data of the first surface portion of tissue;
- update the first model by modifying only at least a portion of the surface data representative of the first surface portion of tissue according to the user input using at least a portion of the rescan data including the first surface portion of tissue;
- and
- output the updated first model of the patient's teeth with the at least the portion of the surface data updated using the rescan data.
A system for accounting for changes in surface topology when scanning a patient's teeth for a dental procedure, the system comprising:
- a hand-held intraoral scanner;
- and
- a computer system operatively connected to the hand-held intraoral scanner and comprising instructions that, when executed by the computer system, causes the computer system to:
- receive initial scan data of a first surface portion of a prepared tooth and a second surface portion of the prepared tooth from the hand-held intraoral scanner, the first surface portion of the prepared tooth having a first surface topology, the initial scan data associated with a first plurality of captured images of a patient's prepared tooth, the initial scan data being received from the hand-held intraoral scanner at a first time;
- display a first model of the patient's prepared tooth, wherein the first model of the patient's the prepared tooth is based on the initial scan data of the patient's prepared tooth and comprises surface data representative of the first surface portion of the prepared tooth and the second surface portion of the prepared tooth;
- receive user input, via the displayed first model, removing the surface data representative of the first surface portion of the prepared tooth and keeping the surface data representative of the second surface portion of the prepared tooth;
- receive, at a second time, rescan data of the patient's prepared tooth from the hand-held intraoral scanner, the rescan data including surface data representative of the first surface portion of the prepared tooth and the surface data representative of the second surface portion of the prepared tooth;
- update the first model by adding the rescan data including surface data representative of the first surface portion of the prepared tooth without modifying the surface data representative of the second surface portion of the prepared tooth;
- and
- output the updated first model of the patient's teeth updated using the rescan data.
