Abstract
Methods and apparatuses for taking, using and displaying three-dimensional (3D) volumetric models of a patient's dental arch. A 3D volumetric model may include surface (e.g., color) information as well as information on internal structure, such as near-infrared (near-IR) transparency values for internal structures including enamel and dentin.
Claims20
A method of tracking a region of a patient's dental arch over time, the method comprising:
- collecting a first three-dimensional (3D) volumetric model of the patient's dental arch, wherein the 3D volumetric model includes surface values and near-infrared (near-IR) transparency values for internal structures within the dental arch;
- identifying a region of the 3D volumetric model;
- flagging the identified region;
- collecting a second 3D volumetric model of the patient's dental arch;
- and
- displaying one or more images marking, on the one or more images, a difference between the first 3D volumetric model and the second 3D volumetric model at the flagged region.

A method of tracking a region of a patient's dental arch over time, the method comprising:
- collecting a first three-dimensional (3D) volumetric model of the patient's dental arch taken at a first time, wherein the 3D volumetric model includes surface color values and near-infrared (near-IR) transparency values for internal structures within the dental arch;
- identifying, using an automatic process, a region within the 3D volumetric model to be flagged from a first record of a plurality of records, wherein each record comprises a plurality of images of a patient's dental arch each taken using an imaging modality, further wherein each record of the plurality of records is taken at a different imaging modality;
- flagging the identified regions;
- correlating the flagged region with each of the records of the plurality of records by correlating the 3D volumetric model of the patient's dental arch with each of the records of the plurality of records;
- collecting a second 3D volumetric model of the patient's dental arch taken at a separate time;
- and
- displaying a difference between the first 3D volumetric model and the second 3D volumetric model at the flagged region.
4 more elements
A method of tracking a dental feature across different imaging modalities, the method comprising:
- collecting a first three-dimensional (3D) volumetric model of the patient's dental arch, wherein the 3D volumetric model of the patient's dental arch includes surface values and internal structures within the dental arch;
- identifying a region of the patient's dental arch from a first record of a plurality of records, wherein each record comprises a plurality of images of a patient's dental arch each taken using an imaging modality, further wherein each record of the plurality of records is taken at a different imaging modality;
- flagging the identified region in a corresponding region of the 3D volumetric model of the patient's dental arch;
- correlating the flagged region with each of the records of the plurality of records by correlating the 3D volumetric model of the patient's dental arch with each of the records of the plurality of records;
- and
- saving, displaying and/or transmitting images including the region of the patient's dental arch.
3 more elements
A system comprising:
- one or more processors;
- and
- a memory coupled to the one or more processors, the memory configured to store computer-program instructions, that, when executed by the one or more processors, perform a computer-implemented method comprising:
- collecting a first three-dimensional (3D) volumetric model of the patient's dental arch, wherein the 3D volumetric model of the patient's dental arch includes surface values and internal structures within the dental arch;
- identifying a region of the patient's dental arch from a first record of a plurality of records, wherein each record comprises a plurality of images of a patient's dental arch each taken using an imaging modality, further wherein each record of the plurality of records is taken at a different imaging modality;
- flagging the identified region in a corresponding region of the 3D volumetric model of the patient's dental arch;
- correlating the flagged region with each of records of the plurality of records by correlating the 3D volumetric model of the patient's dental arch with each of the records of the plurality of records;
- and
- saving, displaying and/or transmitting images including the region of the patient's dental arch.
