METHOD FOR DETERMINING A MAP OF THE CONTACTS AND/OR DISTANCES BETWEEN THE MAXILLARY AND MANDIBULAR ARCHES OF A PATIENT
The invention relates to a method for determining a map of the contacts and/or distances between the teeth of the maxillary arch and the mandibular arch of a patient, characterised in that it comprises the following steps: obtaining the mandibular kinematics recorded on the patient; obtaining surface grids of the maxillary arch and the mandibular arch and resetting said grids relative to one another; creating a reduced grid of at least one of said arches, comprising the selection, in the grid of said arch, of the grids in which the nodes are located at a distance of less than 1 cm from the grid of the opposite arch; creating, for each grid of said reduced grid, a bounding box comprising a plurality of voxels surrounding said grid; using the mandibular kinematics, calculating a network of contacts comprising, for each voxel of the bounding box, information on the existence of a contact between said voxel and a node of the grid of the opposite arch during a relative movement of the mandibular arch in relation to the maxillary arch.
The invention relates to a method for modeling the mandibular kinematics of a patient. Said method includes: acquiring at least one stereoscopic image of the face of the patient by means of a stereoscopic camera; building, from said stereoscopic image, a three-dimensional surface model of the face of the patient; identifying characteristic elements of the face of the patient on said stereoscopic image or on said three-dimensional surface model of the face of the patient; determining reference points, axes, and planes for the face of the patient on said stereoscopic image and on said three-dimensional surface model of the face of the patient, respectively, on the basis of said characteristic elements; obtaining a three-dimensional model of the maxillary dental arch and a three-dimensional model of the mandibular dental arch of the patient; registering the three-dimensional models of the dental arches relative to the reference planes of the three-dimensional surface model of the patient; recording the mandibular kinematics of the patient; and applying said recorded mandibular kinematics to the three-dimensional models of the registered dental arches such as to animate said three-dimensional models.
The invention relates to a method for designing a dental appliance for a facial skeleton including dental crowns and the roots corresponding thereto, said method including the following steps: producing a volumetric image of the facial skeleton, in the form an initial digital file, using medical imaging; modifying said volumetric image by means of the computer processing of said initial digital file, and obtaining a modified digital file, said modification including at least one tooth movement with a view to implementing a desired correction of the dentition; designing said dental appliance using said initial digital file and said modified digital file, and producing a file capable of being used by digitally controlled machines capable of manufacturing a dental appliance. In the step of modifying the volumetric image, for each tooth that is moved, the crown thereof is individualized and the root corresponding thereto is associated therewith, characterized in that said volumetric image of the facial skeleton includes the image of the mandibular joint and a record of the movements of the mandible over the course of a plurality of movements of said mandible, so as to account for the possible movements of said joint after capturing the movement of said mandible.
