Abstract: A method for generating optimal arch forms for a patient's dental arch is presented. The method comprises: receiving first positional digital data for one or more teeth from a reconstructed 3D digital volume of the patient dental arch; (b) generating second positional digital data for the one or more teeth according to a desired dental arch form for the patient; (c) calculating a first displacement data for one or more teeth according to the first positional and second positional digital data; (d) detecting teeth collision values based on the first displacement data; (e) calculating a second displacement data for one or more teeth based on the detected teeth collision values; and (f) reporting a combination of the first displacement data and second displacement data for repositioning one tooth or more teeth of the dental arch.

Abstract: At least one embodiment of a method for dynamically assisting a practitioner in preparing a dental bone grafting operation, the method comprising:—providing an image representing a 3D volume of a portion of a jaw member where bone grafting is to be carried out;—adding to the image a representation of a 3D virtual object representing dental bone graft material;—estimating a value of a geometric characteristic relating to the bone graft material to be used, as a function of geometric characteristics of the represented 3D virtual object;—enabling a user to modify the representation of the 3D virtual object; and—upon modification of the representation of the 3D virtual object, updating the estimated value of the geometric characteristic, according to the modification of the representation of the 3D virtual object, the estimated value assisting the practitioner in determining the dental bone graft material needed.

Abstract: A method and system for fabricating a dental appliance for orthodontic treatment. The method comprises the steps of obtaining three-dimensional dental data from a patient scan, locating initial tooth positions, generating optimal arch forms, and determining a digital model for fabricating an orthodontic aligner with additive device. The system comprises a scanning apparatus to acquire three-dimensional dental data, and a computer apparatus programmed with instructions for generating optimal arch forms, and determining a digital model for fabricating an orthodontic aligner with additive device.

Abstract: A method for intraoral imaging generates one or more output imaging signals from an intraoral probe and acquires multimodal image content from intraoral surface locations according to tissue response from the one or more imaging signals and associates spatial coordinates to the acquired multimodal image content. A surface contour of the patient dentition is generated by stitching the acquired multimodal image content and preserving the association of spatial coordinates with the stitched multimodal image content. Tooth outlines for one or more teeth are generated from the generated surface contour and the generated outlines arranged as a dental chart representing a spatial ordering of the one or more teeth and of supporting gum tissue adjacent to the teeth. The dental chart is populated by analyzing the acquired multimodal image content and associating the analysis to positions on the dental chart according to the preserved association of spatial coordinates and is displayed.

Abstract: Method for allowing patient review of virtual restoration element in video of dentition. At least one restoration element for at least one selected tooth of patient dentition is designed using 3D dentition models based on CAD/CAM techniques. Then, real-time video of the patient's dentition including the at least one selected tooth is displayed, where the video orientation is controlled by the patient. Then, the displayed real-time video of the dentition is modified in real-time including the at least one selected tooth to show the at least one restoration element registered to physical teeth in the real-time video of dentition to replace the at least one selected tooth in the modified displayed real-time video of the dentition.
