Abstract: A method, system and computer readable storage media for proposing and visualizing orthodontic treatments. A patient may use a mobile device such as a smart phone to quickly and inexpensively visualize an orthodontic treatment for misaligned teeth and overlay it on a 3D model of the face and jaw, with a depth sensor being used to detect depth information. The orthodontic treatment may also be visualized in an augmented manner for a clinician. 3D data of the orthodontic treatment may be used for further analysis or fabrication of a treatment appliance.

Abstract: The invention relates to a system and a method for determining the color of teeth or tooth surfaces, wherein the system comprises a 2D or 3D camera and an attachment on said camera, which sets a geometry of a captured image in such a way that, compared to capturing an image without the attachment, the distance, spatial angle and orientation of tooth surfaces relative to the camera are restricted. The attachment according to the invention can in particular be fitted to the camera in a simple manner.

Abstract: A method and system for dynamically providing visual feedback about a quality of data collected during intra-oral scanning Images or light patterns are projected onto an object such as teeth for 3D measurement and for relaying feedback about a quality of the 3D measurement to a user. In this way unsuccessful registrations surface areas of the teeth that have not been acquired yet may be corrected by informing the user to repeat scans at corresponding locations in the intra-oral cavity.

Abstract: A method, system and a computer readable storage media for operating dental machines through an augmented reality control interface A hands free interface may enable the control of a dental machine during dental treatment by using dexterous parts of the body other than the upper limbs (e.g. by using the lower limbs) on a first user/control interface to send instructions corresponding to a second user/control interface that is different from the first user/control interface.
