    摘要： A method for fabricating a dental restoration is described which comprises the steps of obtaining a dental impression of a patient using dental impression material, filling the cavity defining the impression with a filler material distinguishable from the dental material defining the impression and allowing the materials to harden to a solid block, successively removing from the block thin layers and imaging each then remaining surface of the block after each successive layer is removed to define a contour of the filler material for each layer removed, each contour corresponding to a contour of the teeth, gums and palate of the patient at a corresponding known depth of the block, generating a three dimensional computer model of the teeth, gums and palate of the patient using the contours, and converting the model to a stereolithography file for producing a castable pattern of the model or machining a restoration corresponding to the model.

    摘要： The present invention relates to improved biomedical implantable material comprising a plurality of pores, of which one or more of the pores are interconnected below the surface of the material. The improved biomedical implantable material may be used in biomedical implant devices such as orthopedic implants, spinal implants, neurocranial implants, maxillofacial implants, and joint replacement implants. The present invention also relates to a method of preparing an improved biomedical implantable material, comprising subjecting an implantable material to a pore-forming treatment and optionally further subjecting the material to a surface-modifying treatment. The biomedical implantable material may be used in other applications, which as applications where two surfaces are contacted and bonding between the surfaces is required.
