  • Publication number: 20200253692
    Abstract: The present invention is drawn to methods and means for easily, quickly and inexpensively producing one or more dental restorations—suited to each individual patient's needs, and having high quality and excellent fit—thereby reducing fit-issues and consequent rejections by patients. This is accomplished by a process which includes, scanning tooth/teeth of interest to create an “external prep” data file, preparing the tooth/teeth of interest for the dental restoration, scanning the prepared tooth/teeth of interest and saving this in an “internal prep” data file, volumetrically registering the “external scan” and the “internal scan” data files to each other in “digital space,” shaping both the inside and outside a generic dental restoration blank shell based on the “external prep” and “internal prep” data files to produce a patient-specific dental restoration, and then fastening the prepared dental restoration to the tooth/teeth of interest.

  • Publication number: 20030228559
    Abstract: This invention relates to a device to assist a person reading printed text and writing text and, more specifically, to such a device which simplifies and stimulates interest in reading and writing, and methods of use thereof. In an embodiment of this invention, a transparent medium has a plurality of parallel lanes placed thereon. Coloring is placed along the lanes. In another embodiment, there is a lane generator, and a tint generator produces a tinted coloring wherein a printed text located within the lanes is displayed on an electronic medium. Visual perception of the lanes having the coloring aids to simplify and stimulate reading and writing.

  • Patent number: 6641340
    Abstract: The present invention is directed to enhancing the accuracy with which tooth restorations are performed, including the manner by which a tooth is prepared and fit with a dental prosthetic, such as a crown or bridge. Further, the present invention is directed to reducing the skill-dependent tasks associated with tooth restoration, including root canals, while at the same time, improving the precision with which these procedures are performed and by aesthetics of the prosthetic. By improving the accuracy of restoration procedures, any need to repeat these procedures for a given patient can be eliminated and patient comfort can be improved. In addition, by improving the precision with which a prosthetic is prepared for attachment to the prepared tooth of a patient, and/or fit to patient, durability and longevity of the prosthetic are improved.

  • Patent number: 6527550
    Abstract: The present invention is directed to enhancing the accuracy with which tooth restorations are machined, using a device which can accurately copy mill a dental prosthetic blank from a previously formed dental prosthetic model, and which can closely replicate the feel of a dental tool to which dentists are accustomed. The device uses a tool supported on a linear rotary axis to mill the dental prosthetic blank. In addition, exemplary embodiments are directed to the preparation of a hybrid dental prosthetic blank which can be easily machined.
