A dental prosthesis is made by first forming a model of a patient's dentition.
A three dimensional digital data corresponding to the surfaces of the model is
then created. Based on this data, a three dimensional digital data file is then
created substantially corresponding to the dental prosthesis to be manufactured.
The three dimensional digital data of the dental prosthesis to be manufactured
is next transmitted to automated prototyping equipment, and using the automated
prototyping equipment, a wax pattern of the dental prosthesis is manufactured based
upon this three dimensional digital data of the dental prosthesis. Finally, using
this wax pattern in the lost wax investment casting process, the dental prosthesis
is made. Prior to investment casting, marginal edges of the wax pattern are adjusted manually.
