A casting chamber for casting a physical tooth model representing a
patient's tooth includes a chamber body and a lid. The chamber body
includes a cavity adapted to hold a negative impression of the patient's
tooth and to receive a cast material, wherein the negative impression and
the chamber body are registered by a registration unit. The chamber lid
is configured to seal the cast material in the casting chamber to permit
the casting material to solidify in the casting chamber to form a
physical tooth model representing the patient's tooth.
