Embodiment Construction

[0068] The following is a detailed description of exemplary embodiments, with reference to the accompanying drawings, in which like reference numerals identify like structural elements in each of the several views.

[0069] Where they are used, the terms "first", "second", etc. do not necessarily denote any ordinal or priority relationship, but may be used to more clearly distinguish one element or time interval from another.

[0070] The term "exemplary" indicates that the description is used as an example, not to imply that it is ideal or preferred.

[0071] The term "in signal communication" as used in this application means that two or more devices and / or components are capable of communicating with each other via signals traveling over some type of signal path. Signal communication can be wired or wireless. The signal may be a communication signal, a power signal, a data signal or an energy signal, which may transfer information, power and / or energy from a first device a...

Abstract

A method for generating a digital model of dentition, executed at least in part by a computer, acquires a 3-D digital mesh that is representative of the dentition along a dental arch, including includes braces, teeth, and gingival tissue. The method modifies the 3-D digital mesh to generate a digital mesh dentition model by processing the digital mesh and automatically detecting one or more initial bracket positions from the acquired mesh, processing the initial bracket positions to identify bracket areas for braces that lie against tooth surfaces, identifying one or more brace wires extendingbetween brackets, removing one or more brackets and one or more wires from the dentition model, and forming a reconstructed tooth surface within the digital mesh dentition model where the one or morebrackets have been removed. The modified 3-D digital mesh dentition model is displayed, stored, or transmitted over a network to another computer.

Description

technical field [0001] The present disclosure relates generally to manipulating elements represented by three-dimensional meshes, and more particularly to methods and apparatus for crown surface characterization in surface profile images that have been obtained using reflectance imaging. Background technique [0002] Dental / orthodontic practitioners are increasingly interested in using three-dimensional (3-D) imaging and 3-D image processing for computer-aided diagnosis, for prosthetic design and manufacturing, and for overall improved patient care . For cephalometric and analysis, 3-D imaging and 3-D image processing offer significant advantages in terms of flexibility, accuracy, and reproducibility. 3-D cephalometric analysis overcomes some of the disadvantages associated with conventional methods of two-dimensional (2-D) cephalometric analysis, such as 2-D geometric errors such as perspective projection, magnification, and head positioning in the projection . 3-D cepha...
