System and methods for casting physical tooth model

Abstract

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.
