Abstract: A method of designing a dental prosthetic is provided. The method includes converting a scanned model of at least part of a mouth of a patient into an object file adapted to be read by a three dimensional sculpting software application, and importing the object file into the three dimensional sculpting software application. The method also includes selecting a virtual target surface for the dental prosthetic in the object file, and forming a virtual negative surface from the virtual target surface. The method further includes building a dental prosthetic object file from the virtual negative surface. The dental prosthetic object file corresponds in shape to the dental prosthetic. A computer-readable medium having stored thereon computer-executable instructions is provided. The computer-executable instructions cause a processor to perform a method for creating a dental prosthetic when executed.
