Conventionally dental crown manufacturing was done by Investment Casting only. This process goes through various steps. Each step adds error to the final part. It is very tedious for manufacturer to follow individual steps for each patient. This work presents the Rapid Prototyping as a best tool for dental prosthesis and crown manufacturing. Requirement of Rapid Prototyping system is CAD model in .Stl File Format. Two methodologies were used for CAD models development. First type of CAD model was constructed with Dental wings client software and 3S laser scanner. Dental cast model was used for scanning which was prepared for particular patient after preparation of tooth. MIMICS software was used for the development of 3D model of required tooth using CT scan images. Alternate different thicknesses crown models were prepared from MIMICS tooth model using 3-MATIC software. Both the Methodology provides CAD models in .stl file format which can be manufacture with RP system.
