Impression procedure for creating a partial auricular prosthesis

Severe anatomic undercuts associated with tissue remnants or a defect site can often be an obstacle in achieving an accurate impression for a facial prosthesis. This article describes a procedure that overcomes the problems encountered in achieving an accurate impression. The distinct properties of 2 impression materials are applied to create a 3-piece impression that can be reassembled to develop an accurate stone master cast. (J Prosthet Dent 2000;83:648-51.)
