摘要： An intra-oral scanning device includes a light source and an optical system, and communicates with a display system. The device captures images of an object of interest, e.g., patient teeth or associated anatomy, by projecting the light source as a first series of frames, and a second series of frames. The first series of frames projects first pattern data, and the second series of frames projects second data. The second series of frames are interleaved between frames in the first series of frames. The frames in the first series are partially-illuminated and are used to capture data for a 3D model. The frames in the second series are preferably fully-illuminated and are used to generate a live preview of the object. By displaying the live preview frames in juxtaposition to the 3D model, the operator is provided with visual feedback of the object.

摘要： A method and apparatus are provided for a swept source optical coherence tomography (OCT) system utilizing a fast scanning mechanism in the sample arm and a slowly swept light source. The position data is collected rapidly while the wavelength of the source is swept slowly. The system reduces the sweep speed requirements of the light source enabling higher power, greater imaging range, and linear sweeps of the source frequency. The OCT components (or most of them) may be implemented within a hand held imaging probe. In operation, a triangulation scan may be used to orient the imaging probe with respect to a fixed coordinate system; preferably, OCT data captured by the device is then transformed to that same orientation with respect to the fixed coordinate system to improve the scanning results.

摘要： The present disclosure describes methods, systems, and devices for combining multiple images onto a 3D model. The textures of the images are applied to the 3D model dynamically so that the textured 3D model is viewable from different viewpoints in real time. The present disclosure also describes methods, systems, and devices for selecting the images and portions of the selected images to map to defined areas of the 3D model. In addition, the present disclosure describes how to remove the effects of directional lighting from the images. Some aspects of the present disclosure are particularly useful in the context of dental preparations. In some instances, a 3D digitizer is used to produce 3D models of dental preparations that are rendered on a display in real time and are fully 3D dimensional, while accurately depicting the surface textures of the item(s) being digitized.

摘要： A method of producing a crown for a custom implant abutment is carried out as follows. The method begins by preparing a patient's existing dental structures, viz., positioning a dental implant in the patient's mouth. Using a scanner device and associated modeling software, a first 3D model is obtained of a sufficiently large portion of an implant abutment to be attached to the implant. This scan is performed extra-orally. Preferably, the sufficiently large portion is that portion of the abutment bounded by a margin curve. After the implant abutment is attached to the implant (intra-orally), the scanner is used to obtain a second 3D model of the implant abutment attached to the implant (i.e., an intra-oral scan). Using the modeling software, the first 3D model is then aligned to the second 3D model. Thereafter, a boundary curve on the first 3D model is identified. Using the boundary curve to trim the first 3D model, the system then produces a third 3D model. Using the boundary curve, the third 3D model and the second 3D model, the system then creates a fourth 3D model, which is a model of a virtual dental item. Using a computer-assisted milling machine, the model of the virtual dental item is then used to produce an actual crown, which is then attached to the implant to complete the process.
