Abstract
An image processing method for use in dentistry or orthodontic is provided. Two images of teeth one being a two-dimensional image and one a three-dimensional image are combined in a manner to allow the use of information obtained from one to the other. In order to combine the two images a set of basic landmarks is defined in one, identified in the other and then the two images are registered.
Claims23
An image processing method comprising:
- (a) applying at least a first imaging technique and a second imaging technique to acquire a first, two-dimensional image of at least a first portion of teeth and a second three-dimensional virtual image of at least a second portion of the teeth, respectively, there being at least a partial overlap between said first and second portions;
- and
- (b) defining a set of basic landmarks in either one of the two images, locating said set in the other of the two images and registering said set in the two images.
A method according to any one of claims 14, wherein step (a) comprises applying a third imaging technique to acquire a third image comprising at least a profile of facial aspects.
A method according to any of claims 14, wherein said three-dimensional image comprises substantially all teeth of at least one jaw, and the two-dimensional image is positioned on the mid palatal plane of the three-dimensional image.
An image processing system comprising:
- (i) a first utility for receipt of first data representative of a first two-dimensional cross-sectional image of at least a first teeth portion;
- (ii) a second utility for receipt of second data representative of a second, tree-dimensional virtual image of teeth model of at least a second teeth portion;
- (iii) a module for defining basic landmarks in both images and for generating data representative thereof;
- and
- (iv) a processor associated with said first and said second utility and with said module, for receiving said first and said second data and for mapping elements in one of the two images to the other of the two images according to the data representative of said basic landmarks.
