Accurate ear impressions are vital for prosthetic reconstruction. This study presents a novel technique using a custom wax tray and hydrocolloid to reduce distortion during ear impression procedures.

Area of Science:

  • Medical device technology
  • Prosthodontics
  • Anaplastology

Background:

  • Surgical or prosthetic ear reconstruction is required for various conditions.
  • Precise ear impressions are crucial for fabricating auricular prostheses.
  • Existing impression methods can be prone to distortion.

Purpose of the Study:

  • To describe an improved technique for taking ear impressions.
  • To minimize distortion during the ear impression process for prosthetic fitting.

Main Methods:

  • Utilized a wax-customized, rigid impression tray.
  • Employed irreversible hydrocolloid material for capturing the ear anatomy.
  • Focused on minimizing distortion during the impression procedure.
