Comparison of two impression techniques for auricular prosthesis: Pilot study. J Rehabil Res Dev. 2013;50(8):1079–88. Slideshow Project DOI: /JRRD JSP Aim – Compare accuracy of new impression technique (triple-layer impression technique [TLIT]) with conventional impression technique (CIT) to fabricate auricular prostheses. Relevance – Impression techniques play vital role in accurate reproduction of affected and unaffected ears, orientation of ear during wax try-in, and fabrication of ear prostheses.

Comparison of two impression techniques for auricular prosthesis: Pilot study. J Rehabil Res Dev. 2013;50(8):1079–88. Slideshow Project DOI: /JRRD JSP Method 10 markings made on subjects’ ears. – For 5 measurements: super aurale–sub aurale, pre aurale–post aurale, A–A1, B–B1, and C–C1) Custom-made trays recorded impressions in CIT and TLIT using alginate. – Models were cast with type IV gypsum product. Markings were transferred on cast and measures were rechecked. Evaluated: – Distribution analysis of measurement differences between CIT and TLIT. – Subject’s actual values.

Comparison of two impression techniques for auricular prosthesis: Pilot study. J Rehabil Res Dev. 2013;50(8):1079–88. Slideshow Project DOI: /JRRD JSP Results Statistically significant differences found in measurements A–A1, B–B1, and C–C1 between the two techniques compared with subject’s actual dimensions (p < 0.01). TLIT found to produce accurate models compared with CIT.

Comparison of two impression techniques for auricular prosthesis: Pilot study. J Rehabil Res Dev. 2013;50(8):1079–88. Slideshow Project DOI: /JRRD JSP Conclusion TLIT was cost effective, less technique sensitive, and tailor made to reduce chairside orientation time in wax try-in appointments for rehabilitation patients, especially those with unilateral auricular defects.
