A method for segmenting a 3D model image of a patient's dentition obtains a first 3D model image of the patient dentition and obtains a first segmentation of the first 3D model image, wherein the first segmentation provides at least a tooth surface contour and a tooth label for one or more teeth of the first 3D model. A second 3D model image of the patient dentition is obtained. Each segmented tooth surface contour of the first 3D model is registered to corresponding tooth surface contour of the second 3D model. A second segmentation of the second 3D model image is obtained according to the registered tooth surface contour, wherein the second segmentation similarly provides at least tooth surface contour and a tooth labeling for one or more teeth of the second 3D model image. The segmented second 3D model image is displayed, transmitted, or stored.

Tooth segmentation using tooth registration

A method for visualizing patient dentition acquires a contour image of patient dentition and segments the contour image to identify one or more segmented teeth. At least one deciduous tooth among the one or more segmented teeth is identified. A virtual model of a target dentition arrangement of the patient dentition is generated, wherein the at least one deciduous tooth is replaced by a replacement permanent tooth.

Method for virtual setup with mixed dentition

The invention concerns a method for obtaining operating parameters for an x-ray CBCT imaging apparatus in view of acquiring a set of data of a patient's maxillofacial region. The method comprises: identifying a patient's maxillofacial first region of interest (ROI1), determining a height of a horizontal plane of said patient's maxillofacial first region of interest (ROI1) when the patient is in an occlusion position or bites a patient positioning accessory, acquiring through a slit-shaped collimator window a first set of data relative to said patient's maxillofacial first region of interest (ROI1) including the horizontal plane using x-ray CBCT imaging, reconstructing an axial CBCT slice comprising the horizontal plane based on the first set of data relative to the patient's maxillofacial first region of interest (ROI1), displaying the reconstructed axial CBCT slice of the patients maxillofacial first region of interest (ROI1) from the acquired first set of data, defining at least partially a second region of interest (ROI2) based on the displayed reconstructed axial CBCT slice of the patient's maxillofacial first region of interest (ROI1) and intersecting the latter, obtaining operating parameters for an x-ray CBCT imaging apparatus based on at least the defined second region of interest (ROI2) in view of acquiring a second set of data including the defined second region of interest (ROI2).

Method and system for obtaining operating parameters for 3D x ray acquisition

Method for automatically assigning numeric labels to teeth in a dental arch map provides a segmented 3D surface image of patient dentition having identified individual teeth and determined tooth position in the dental arch. A tooth contour for the identified teeth is defined. The tooth type is identified as one of incisor, canine, premolar, or molar. A display of the tooth contour is labeled with an assigned tooth number according to the tooth position, tooth contour, and tooth type. The labeled mapping is displayed.

Dynamic dental arch map

Certain exemplary method and/or apparatus embodiments herein can include&#x2014;acquiring a set of data relative to a patient's maxillofacial region through an x-ray CT imaging apparatus, &#x2014;reconstructing two or more types of maxillofacial data volumes from the same acquired set of data, &#x2014;displaying at least one slice of the patient's maxillofacial region with a first type of data volume among the volumes (e.g., FDK volume and MAR volume), &#x2014;selecting a region of interest (ROI) in the displayed at least one slice, a first portion of said first type of data volume being displayed within the ROI, &#x2014;displaying within the selected ROI a second portion of a second type of data volume, the at least one slice of the patient's maxillofacial region being displayed with the first type of data volume while the ROI is displayed with the second portion of the second type of data volume.

X-ray CT imaging method, interface system and apparatus

The invention concerns a dental imaging apparatus comprising: &#x2014;a support frame, &#x2014;a movable gantry that comprises two opposite arms respectively supporting an x-ray source and an x-ray sensor facing the x-ray source, &#x2014;a movable patient positioning arm connected to the support frame, &#x2014;two cameras positioned on the gantry arm supporting the x-ray source and on the positioning arm so as to respectively acquire side and front images of a patient's head, &#x2014;a display assembly configured to simultaneously display in real time a side image and a front image of the patient's head taken by the two cameras.

Dental imaging apparatus with improved patient positioning

A method for generating a dental arch map for a patient acquires a 3D surface image of patient dentition and automatically segments the 3D surface image to identify individual teeth. A mapping of outlines is formed for the identified teeth. The mapping is labeled according to a tooth numbering scheme and the labeled mapping is displayed.
