A two-step functional impression technique for the fabrication of an implant-retained silicone auricular prosthesis

Abstract

Excessive movement of the underlying tissue bed can lead to poor retention of an implant-retained silicone auricular prosthesis. This article describes a 2-step impression technique with a secondary functional pickup impression of the wax pattern. A wide range of tissue movements can be recorded while maintaining a stable relationship between the abutment analog assembly and retentive elements. The definitive cast is modified accordingly to provide an accurate reproduction of the patient's tissues during function, thus, increasing the overall retention and stability of the definitive prosthesis.
