Abstract

A preparation kit for preparing dental prosthetic devices in-house at the site of a dental procedure, without requiring an external third-party lab to prepare the final prosthetic device. The kit contains a porous block, a thermoset polymeric resin, and an initiator, where the resin and initiator are both packaged in substantially airtight and substantially opaque packaging. The resin and initiator are combined together to form a resin mixture which is then infiltrated into the pores of the porous block to form an esthetic material. A digital scan of at least a portion of a patient'"'"'s jaw is used to provide the desired shape of the dental device to a cutting mechanism, which then cuts the filled or un-filled porous block based on the shape provided to it from the digital scan.
