In vitro considerations in the production of dimensionally accurate earmoulds. I. The ear impression.
As the first part of a study on the fabrication of earmoulds, the dimensional accuracy and stability, as a function of time, of a wide range of polymer-based impression materials has been studied. The results demonstrate that addition cured silicones are the most promising materials in terms of their accuracy and dimensional stability.
