Abstract: A method is provided for enhancing the results of an optical scan of the surface of an object such as human dentition in which the surface may be dry or wet. The method includes the step of applying a composition to the surface, wherein the composition includes a volatile component that rapidly evaporates resulting in the transformation of the residual composition to a durable, water insoluble, non sticky film on the surface, whether applied in a dry-field or in a wet-field environment. The composition generally includes an agent that improves the quality of the optical return signal to a 3D optical scanner. The method further includes the steps of scanning the surface having the film with an optical scanner and then, once scanning has been completed, using an organic solvent, such as a mouthwash containing alcohol, to remove the film from the object's surface.

Abstract: Systems and methods are disclosed to fabricate a restorative prosthesis. The system includes a scanner to intra orally capture color and translucency information along with a three dimensional (3D) shape of the dentition being reconstructed. The system also includes a computer aided design (CAD) module to receive the color and translucency information and the 3D shape to render a color accurate representation of the prosthesis for review, wherein the color, translucency and surface information is combined in a single digital prescription which is electronically transferred to a laboratory or CAD/CAM system for fabrication. The system provides the capability for 3D shape, color and translucency characteristics of the final prosthesis to be measured and quantitatively compared to the prescribed requirements.

Abstract: Systems and methods are disclosed to preview a scan includes placing a three dimensional (3D) scanner probe near an object to be scanned; scanning a portion of the object to generate a 3D model of the scanned portion of the object; and displaying the 3D model of the portion as a live 3D preview of the 3D model, wherein the live 3D preview provides feedback on the probe's position and orientation relative to the object.

Abstract: Methods and systems for treating teeth include capturing a digital dental model taken within an oral cavity; modifying the digital model in planning a dental treatment or in designing a tooth die model for a dental prosthetic; creating physical models from the original or modified digital models: and using the physical models as a pattern for fabrication and fit check of a dental prosthetic.

Abstract: Systems and methods optically image a dental structure within an oral cavity by: directing air at a tooth-gum interface of the dental structure through at least one air nozzle movably coupled to an intra-oral track; coating the dental structure with a substance to enhance the image quality; and capturing one or more images of the dental structure through at least one image aperture, the image aperture movably coupled to the intra-oral track.

Abstract: A system optically images a dental structure within an oral cavity. The system includes an intra-oral track adapted to be inserted inside the oral cavity; an image aperture movably coupled to the intra-oral track and adapted to capture one or more images of the dental structure; and an image processor coupled to the image aperture to generate a three-dimensional (3D) model of the dental structure based on the images captured by the image aperture.
