Abstract
There is provided a method for producing a dental prosthesis comprising: obtaining three-dimensional digital data relating to a patient's dentition; designing a virtual prosthesis for the dentition using the three-dimensional digital data; transmitting digital data corresponding to the virtual prosthesis to an automated prototyping system; producing a prototype of the dental prosthesis with the automated prototyping system, the prototype made of a material that can be ablated; covering at least the prototype with a hardening material and removing the prototype from within said hardening material to produce a mold for the dental prosthesis; casting the dental prosthesis by filling the mold with a metal and removing the hardening material.

A method for producing a dental prosthesis comprising:
- obtaining three-dimensional digital data relating to a patient's dentition;
- designing a virtual prosthesis for said dentition using said three-dimensional digital data;
- transmitting digital data corresponding to said virtual prosthesis to an automated prototyping system;
- producing a prototype of said dental prosthesis with said automated prototyping system, said prototype made of a material that can be ablated;

- casting said dental prosthesis by filling said mold with a metal and removing said hardening material.
A method of manufacturing a pattern of a dental prosthesis from a wax material, comprising the steps of:
- (a) forming a model of a patient's dentition including surfaces corresponding to the dental structure nearby the location that the dental prosthesis is to be placed in the mouth of a patient;
- (b) scanning said surfaces of the model to collect three dimensional digital data corresponding to the said surfaces;
- (c) displaying on a monitor screen of computer aided design equipment an image of a proposed dental prosthesis based, at least in part, on the collected three dimensional digital data corresponding to said surfaces;
- (d) with the aid of said computer aided design equipment, modifying said image so that said image displayed on the monitor screen substantially corresponds to the dental prosthesis to be manufactured;
