Abstract: Embodiments of the present invention generate comprehensive and accurate three-dimensional (3D) models of dental anatomy from acquired Cone Beam Computed Tomography (CBCT) data of the dental anatomy and acquired Optical Coherence Tomography (OCT) data of the dental anatomy. Generating the 3D model of the dental anatomy includes identifying one or more pathology volumes within the dental anatomy, based on the CBCT data and the OCT data.

Abstract: A dental robot includes a platform and a suspension system. The suspension system supports the platform and automatically compensates for weights of the platform and a robot arm, end effector, and tooth clamp attached to the platform. The suspension system maintains a constant height of the platform above a base, absent an external force on the tooth clamp. The suspension system allows position and orientation of the platform to change, relative to the base, in response to an external force on the tooth clamp greater than about 0.1 N, such as a result of movement (change in position and/or orientation) of a subject. Consequently, the position and orientation of the platform remain fixed, relative to the subject's teeth, in response to movement of the teeth.

Abstract: An optical coherence tomography scanning system traverses its respective scan pattern quickly, typically completing an entire two-dimensional frame faster than a conventional raster scanner completes one raster line segment. To traverse the scan pattern quickly, the system takes fewer A-scans per length of scan pattern than a conventional OCT scanner. To compensate for the sparsity of the sample points along the respective scan line segments, and for gaps between respective line segments of the trajectory, the system acquires and combines several partially overlapping frames for each study.

Abstract: Provided are systems and methods for generating a three-dimensional model from an intra-oral optical coherence tomography scan.

Abstract: A method and apparatus are disclosed enabling an orthodontist or a user to create an unified three dimensional virtual craniofacial and dentition model of actual, as-is static and functional anatomy of a patient, from data representing facial bone structure; upper jaw and lower jaw; facial soft tissue; teeth including crowns and roots; information of the position of the roots relative to each other; and relative to the facial bone structure of the patient; obtained by scanning as-is anatomy of craniofacial and dentition structures of the patient with a volume scanning device; and data representing three dimensional virtual models of the patient's upper and lower gingiva, obtained from scanning the patient's upper and lower gingiva either (a) with a volume scanning device, or (a) with a surface scanning device. Such craniofacial and dentition models of the patient can be used in optimally planning treatment of a patient.

Abstract: The present invention discloses orthodontic treatment planning which enables designing the desired smile line with the help of a computer workstation. A new lip trace feature enables cutting out the portion of a photograph corresponding to the area inside the lips. The 3D model of the teeth is then completely visible when overlaid with the facial photograph. One can use this feature to superimpose the patient photo over the 3-D model of the teeth to see how much intrusion or extrusion is needed to design the smile line. Three dimensional model of dentition obtained by scanning of teeth along with the patient's two dimensional facial photograph is used to design the desired smile line for the patient by means of software instructions in the workstation.

Abstract: The present invention discloses orthodontic treatment planning using virtual articulator with the help of a computer workstation. A virtual articulator can be activated from the workstation. The virtual articulator displays opening/closing movements, and left/right excursive movements. One can also adjust the angle of the articular eminence to more accurately display the patient's chewing motion. Treatment planning simulation using virtual articulator can detect collision of teeth and lead to a treatment plan that can avoid such collisions. Composite three dimensional models of dentition obtained by scanning of teeth and through CBCT are used in identifying the articulator; which is then used in virtual simulation by means of software instructions in the workstation.
