Abstract

Disclosed is a bur unit for manufacturing a dental workpiece, which mills a blank material such as zirconia with a desired ratio to copy or imitate the upper structure of a tooth or dental implant. The bur unit includes discrete and dedicated burs that are installed on a tracking device and a machining tool to easily track the inner surface of a model body and directly mill the inner surface of a blank material. The bur unit includes a guide tool installed on the tracking device and having a diameter corresponding to an abutment that is coupled to an inner surface of the model body, and a milling tool installed on the machining tool to cut an inner surface of a blank expanded through a primary sintering process. The milling tool has a diameter that is greater than that of the guide tool by a shrinkage rate of the blank after a secondary sintering process.
