Abstract
A method, user interface and system for detecting and monitoring development of a dental condition. In particular, detecting and monitoring such a development by comparing digital 3D representations of the patient's set of teeth recorded at a first and a second point in time. For example, determining tooth movement for at least one tooth between the first and second point in time based on derived distances.
Claims1
A non-transitory computer readable medium encoded with a computer program for causing a processor to perform a method for detecting or monitoring a dental condition of a patient's teeth, wherein the method comprises:
- obtaining a first digital 3D representation of the teeth recorded at the first point in time and segmenting the first digital 3D representation such that a first 3D tooth model is formed for at least one tooth;
- obtaining a second digital 3D representation of the teeth recorded at the second point in time and segmenting the second digital 3D representation such that a second 3D tooth model is formed for the least one tooth;
- aligning the first and second 3D tooth models;
- comparing one or more corresponding regions on the aligned first and second 3D tooth models;
- and
- subsequently detecting a change in a parameter representing a dental condition based on the comparison, wherein, when a detected change exceeds a set threshold, an operator is prompted through a graphical user interface.
