摘要： A digitized image of an object may include representations of portions of th e object that are obscured, occluded or otherwise unobservable. The image may be a multi-dimensional visual representation of dentition. Characteristics of t he dentition and its surfaces, contours, and shape may be determined and/or analyzed. A light may be directed toward and reflected from the dentition. T he reflected light may be combined with a reference to determine characteristic s of the dentition, including obscured areas such as subgingival tissue.

摘要： The present invention relates generally to mill blank constructions to facilitate the manufacture of dental restorations. A given mill blank is formed in a shape (i.e. with a given geometry) that has been predetermined t o reduce material waste when the mill blank is machined into the final part. A set of two or more blanks each having such characteristics comprise a smart blank ~library~. In one embodiment, a smart blank library includes a sufficient number of unique blanks such that, when the geometry of the designed restoration is known, the smart blank with a highest yield can be selected for use in milling the restoration. The ~yield~ of a given smart blank represents the amount of material of the smart blank that is actually used in the final restoration. Automated processes for smart blank inventory management and smart blank selection are also described.

摘要： An intra-oral imaging system (100) has an imaging device (102), a processor (104), and a head mounted display (HMD) (106). The HMD (106) may be worn by an operator (112). The intra-oral imaging system (100) displays a computer- generated image in the HMD (106) which displays a tangible object (108) in a n operator~s view. The computer-generated image may be projected in the field of view of the operator (112).
