The production of impression materials has a long tradition at Dreve.
Our comprehensive Otoform® product range offers the right material with the right properties for every impression. From our world-renowned classic Otoform® AK to the color-changing Otoform A softX®: Rely on our many years of experience in the research and production of first-class impression materials.
The optimum consistencies for every impression situation ensure precise and detailed impressions and, last but not least, trouble-free further processing of the impressions in the earmold laboratory. The easy handling and the short setting times of only 180 seconds provide you with top impressions in record time.
Our popular impression material Otoform® A softX now shows you that the material has cured by changing color.
This involves a chemical reaction of the color pigment in conjunction with the curing process: when the silicone is pink, the impression can be removed. A fingernail test is no longer necessary!
How does it work?
Addition-curing silicones cure in a hydrosilylation reaction under platinum catalysis. By using a color pigment that simultaneously changes its chromophoric structure and thus its color through chemical reaction, it is possible to indicate the curing of Otoform® A softX in the patient's ear by a color change from purple to pink. This color-cure technology makes ear impressioning even easier and safer.
The addition-vulcanizing Otoform® Xpand expands gently in the ear during impression taking.
The impression material is advantageous for soft ear tissue, as it extends in the ear proportionally.
In addition, it is also favorable for the fitting of hearing protection and power hearing aid systems. Otoform® Xpand guarantees a high sealing of earmolds. It is pressure building like a putty material, but allows a simple ear impression taking without much effort thanks to the creamy-fluffy consistency and excellent flowability.
Impression material with a paste-like consistency, which is also absolutely thixotropic and therefore does not flow out of the ear.
After curing, the impression can be easily removed from the ear and has a high tear strength. We recommend Otoform® A soft for pressureless impressions and for CIC devices.
Impression material in pasty consistency, which is at the same time absolutely thixotropic and therefore does not flow out of the ear.
After curing, the impression can be easily removed from the ear and has a high tear strength. Especially recommended for CIC impressions, very narrow ear canals or for pain-sensitive persons.
Proven kneadable impression material, non-sticky and pliable, in a slightly pressure-building consistency.
Uniform but measured pressure is applied to the ear tissue. Otoform® Ak is particularly advantageous in the case of less resilient ear tissue for a perfect fit of the earmolds.
The pink impression material is a soft, smooth-running and non-sticky mousse.
Noticeably elastic, it is pleasant to work with and easy to apply. Due to its special flowability, it is ideally suited for deep ear impressions (CIC).

Otoferm® Protect is ideal for the direct fitting of BTE, splash water plugs (swimming plugs) and hearing protection earmolds. The product is handled like our Otoform® impression materials, has a short curing time and is easy to process. Manufactured earmolds are floatable on the water surface.
