ABSTRACT:This paper aims to describe the stereolithographic rapid prototyping of the ear prosthesis in an anotia case and to evaluate the advantages and disadvantages. Virtual model of the patient’s head was produced from the computerized tomography scan of the patient. Three-dimensional image of the healthy contralateral ear was extracted, inverted and re-located on the virtual model. Data was transferred to the stereolithography unit and the thermoplastic prototype of the prosthesis was made. Prototype was duplicated with set-up wax. Wax prototype was processed with polydimethyl siloxane elastomeric material by using pack and press technique. The system used was easy, time consuming and successful. Nevertheless, high cost and the irradiation during the computerized tomography imaging should be considered.
