    摘要： 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.

    摘要： 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. For example, when the interior of a prosthetic is not precisely fit to the prepared tooth of a patient, as in a case where the coping is undersized relative to the prepared tooth, buckling of the coping can occur. As a result, the buckling of the coping can cause the porcelain exterior of the prosthetic to crack. Because exemplary embodiments of the present invention provide a precise and accurate fit, they avoid such buckling of the prosthetic's interior, and therefore, improve the longevity of the prosthetic.

    摘要翻译： 本发明旨在提高执行牙齿修复的精度，包括牙齿的准备方式和与牙科假体（例如牙冠或牙桥）配合的方式。 此外，本发明旨在减少与牙修复相关的技能依赖性任务，包括根管，同时提高这些程序的执行精度以及假肢美观。 通过提高恢复程序的准确性，可以消除对给定患者重复这些程序的任何需要，并且可以改善患者的舒适度。 此外，通过提高制备用于附着到患者​​准备的牙齿上的假体和/或适合患者的精度，改善了假体的耐久性和寿命。 例如，当假体的内部不准确地配合到患者的准备的牙齿时，如在相对于准备好的牙齿的应对尺寸过小的情况下，可能发生应对的屈曲。 结果，应对的弯曲可能导致假肢的瓷器外部破裂。 由于本发明的示例性实施例提供精确和精确的配合，所以它们避免了假肢内部的这种屈曲，并因此改善了假肢的寿命。
