Abstract: Objective To explore the feasibility of the design and manufacture of a personalized wedge by three-dimen-sional reconstruction technology and rapid proto-typing technology. Methods The head CT scan was performed on a patient with congenital microtia who was prepared for the auriculocephalic angle reconstruction. The 3D image was reconstructed by the CT data and the model of the wedge was designed. Then it was printed by the rapid proto-typing technology. Results A personalized EH composite wedge was acquired. Conclusion It is realizable to design and manufacture a personalized wedge by three-dimensional reconstruction technology and rapid proto-typing technology.

Key words: Three dimensional reconstruction, Rapid proto-typing, Auriculocephalic angle reconstruction
