The recently introduced OtoVent™ EarDam System is designed to reduce the incidence and severity of discomfort for patients during the impression-taking procedure. The EarDam is made from compressible foam that stays compressed for approximately 15-20 seconds, allowing placement deep in the canal without pressure or abrasion against the canal walls. A vent tube that runs through the product allows air to vent behind the impression, eliminating suction on the tympanic membrane. The specially designed OtoControl™ Applicator provides control both in depth as well as in the lateral movement of the EarDam. Any other type of otoblock can also be used with the special OtoControl™ applicator. The Starter Kit includes three sizes of OtoVents™ (12 each), OtoControl™ Applicator and a protective case.

OTOFORM-A/K in tubs is a kneadable standard material, non-sticky and smooth, in a consistency that builds up slight pressure: an even, but dosed pressure is exerted on the ear tissue. In cases of ear tissue with minimal resilience, this is advantageous for the fitting and sealing of the earmolds, reports the company. Application is performed with the DREVE-Impression Syringe “Standard” or “CIC” (final hardness: 35 Shore A). OTOFORM-A/K in the S50 double cartridge is designed as the first non-sticky, kneadable ear impression silicone for the pressure developing impression technique in double cartridges.
