A method for generating a mapping of dental occlusion generates a three-dimensional model of the patient's teeth according to acquired image data. The maxillary and mandibular arches are positioned in opposition in the generated model of the patient's teeth and a meal model generated having characteristics of a foam material. A pressure field distribution for the generated meal model is calculated for one or more pairs of opposed teeth from the generated three-dimensional model of the patient's teeth. The calculated pressure field distribution can be displayed.

Dentition occlusion mapping using elastic foam modeling

A method for generating a mapping of dental occlusion generates a three-dimensional model of the patient's teeth () according to acquired image data. The maxillary and mandibular arches are positioned in opposition in the generated model of the patient's teeth and a meal model () generated having characteristics of a foam material. A pressure field distribution for the generated meal model is calculated for one or more pairs of opposed teeth () from the generated three-dimensional model of the patient's teeth. The calculated pressure field distribution () can be displayed.

Occlusion mapping using elastic foam modeling

A method for displaying teeth of a patient, generates a three-dimensional model of the patient's teeth and displays the generated three-dimensional model. A displayed image shows a cross-sectional view of the teeth according to the position of a cutting plane extending through the three-dimensional model. The relative position of the cutting plane is adjustable according to an operator instruction. The orientation of the displayed cross-sectional view is determined by the position of the cutting plane.

Imaging apparatus for display of maxillary and mandibular arches

The invention relates to a device for measuring dental shade comprising: &#x2014;illumination means (), for successively illuminating at least one part of a tooth (D) with light of various spectral ranges, &#x2014;at least one sensor () sensitive to light coming from said tooth part, in response to the illumination, to generate for each different color of illumination, at least one measurement signal, &#x2014;means () for converting the measurement signals corresponding to said tooth part, into the coordinates of a measurement point (), in a shade space in which 'reference' points () are also defined, corresponding to the preset shades of a dental shade guide, and&#x2014;search means (), for the tooth part, for a shade corresponding to the reference point closest to the measurement point, in the shade space.
