Abstract
A method for visualizing patient dentition acquires a contour image of patient dentition and segments the contour image to identify one or more segmented teeth. At least one deciduous tooth among the one or more segmented teeth is identified. A virtual model of a target dentition arrangement of the patient dentition is generated, wherein the at least one deciduous tooth is replaced by a replacement permanent tooth.
Claims20
A method for visualizing a patient dentition orthodontic treatment comprising:
- acquiring a surface contour model of patient dentition;
- segmenting the surface contour model to identify one or more segmented teeth;
- identifying at least one unerupted tooth within the surface contour model, wherein the at least one unerupted tooth is identified using at least one of three-dimensional volume acquisition or panoramic radiography;
- accessing shape and size information for the unerupted tooth based, at least in part, on the at least one of the three-dimensional volume acquisition or the panoramic radiography;
- identifying a substitute model tooth based at least in part on the shape and size information for the unerupted tooth, wherein the substitute model tooth reflects a replacement permanent tooth model;
- and
- generating a virtual setup of the patient dentition, wherein a location corresponding to the at least one unerupted tooth is replaced by the replacement permanent tooth model.
A method for visualizing a patient dentition orthodontic treatment comprising:
- receiving a plurality of segmented teeth from a virtual model of an initial tooth arrangement;
- identifying at least one unerupted tooth within the surface contour model, wherein the at least one unerupted tooth is identified using at least one of three-dimensional volume acquisition or panoramic radiography;
- accessing shape and size information for the unerupted tooth based, at least in part, on the at least one of the three-dimensional volume acquisition or the panoramic radiography;
- identifying a substitute model tooth based at least in part on the shape and size information for the unerupted tooth, wherein the substitute model tooth reflects a replacement permanent tooth model;
- and
- generating a virtual setup of a target tooth arrangement wherein a location corresponding to the at least one tooth is replaced by the replacement permanent tooth model.
An apparatus for providing a virtual setup for orthodontics assessment, the apparatus comprising:
- an imaging apparatus configured to acquire a surface contour of patient dentition;
- a processor programmed with instructions that
- (i) segment the dentition surface contour to identify one or more segmented teeth;
- (ii) identify at least one unerupted tooth within the surface contour model, wherein the at least one unerupted tooth is identified using at least one of three-dimensional volume acquisition or panoramic radiography;
- (iii) access shape and size information for the unerupted tooth based, at least in part, on the at least one of the three-dimensional volume acquisition or the panoramic radiography;
- (iv) identify a substitute model tooth based at least in part on the shape and size information for the unerupted tooth, wherein the substitute model tooth reflects a replacement permanent tooth model;
- (v) generate a virtual setup of a target dentition arrangement, wherein a location corresponding to the at least one unerupted tooth is replaced by the corresponding permanent tooth model;
- and
- a display in signal communication with the processor, and configured to display the virtual setup.
