Ear impressions

Impressions have to be made from soft silicone material. Dreve, Egger and Westone brands are recommended. It is suggested to use foam or cotton swabs to protect eardrum.

Impressions have to be made past the second bend and shall include: full concha, helix, crus helix, tragus and antitragus.

After injecting impression material into ear the mass needs to be pushed with thumb to remove air bubbles and reduce impression wastage. Typically material cures within 5 minutes. Impressions cannot be taken out before that period.

During the process, mouth should be open with bite-block inserted between teeth in order to maximally stabilize the jaw. If a bite block is unavailable then teeth might rest against something of similar size, for example a thumb. Keeping mouth open at about 2.5 cm in relaxed manner without talking and moving is required for achieving full comfort and isolation of final product.
