Abstract
Capturing obscured areas in an oral cavity of a patient by providing a dental instrument with a camera to capture at least an area of operation of the dental instrument and comparing two-dimensional (2D) images from the camera with a three-dimensional (3D) model of the patient's jaw to compute a position of the camera or dental instrument in relation to the patient's jaw. Information about a deviation of one or more actual dental process parameters from one or more corresponding planned dental process parameters are displayed.
Claims30
A method comprising:
- providing a dental instrument:
- providing a camera fixedly attached to or integrated into the dental instrument;
- capturing, by the camera, invisible or poorly visible areas in an oral cavity of a patient by configuring the camera to capture at least an area of operation of a drill of the dental instrument;
- comparing two-dimensional (2D) images from the camera with a three-dimensional (3D) model of the patient's jaw to compute a position of the camera or dental instrument in relation to the patient's jaw;
- computing a positional relationship between the drill of the dental instrument and the jaw based at least in part on the computed position of the camera or dental instrument and a distance between the drill and the camera or dental instrument;
- computing and presenting information about a deviation of one or more actual drilling parameters from one or more corresponding planned drilling parameters to aid a user during drilling.
A computer system comprising:
- at least one processor configured to perform the steps of:
- providing a dental instrument;
- providing a camera fixedly attached to or integrated into the dental instrument;
- capturing, by the camera, invisible or poorly visible areas in an oral cavity of a patient by configuring the camera to capture at least an area of operation of a drill of the dental instrument:
- comparing two-dimensional (2D) images from the camera with an existing three-dimensional (3D) model of the patient's jaw to compute a position of the camera or dental instrument in relation to the patient's jaw;
- computing a positional relationship between the drill of the dental instrument and the jaw based at least in part on the computed position of the camera or dental instrument and a distance between the drill and the camera or dental instrument;
- computing and presenting information about a deviation of one or more actual drilling parameters from one or more corresponding planned drilling parameters to aid a user during drilling.
A non-transitory computer-readable storage medium storing a program which, when executed by a computer system, causes the computer system to perform a procedure comprising the steps of:
- capturing, by a camera fixedly attached to or integrated into the dental instrument, invisible or poorly visible areas in an oral cavity of a patient by configuring the camera to capture at least an area of operation of a drill of the dental instrument;
- comparing two-dimensional (2D) images from the camera with a three-dimensional (3D) model of the patient's jaw to compute a position of the camera or dental instrument in relation to the patient's jaw;
- computing a positional relationship between the drill of the dental instrument and the jaw based at least in part on the computed position of the camera or dental instrument relative to the jaw and a distance between the drill and the camera or dental instrument;
- computing and presenting information about a deviation of one or more actual drilling parameters from one or more corresponding planned drilling parameters to aid a user during drilling.
A system comprising:
- a dental instrument comprising a drill;
- a camera fixedly attached to or integrated into the dental instrument and configured to capture invisible or poorly visible areas of the areas in an oral cavity:
- a screen configured to display the captured invisible or poorly visible areas of the areas in an oral cavity;
- wherein the screen is further configured to display or present a deviation of one or more actual drilling parameters from one or more corresponding planned drilling parameters to aid a user during drilling
