New 3M ESPE Astringent Retraction paste

New Products Restorative Haemostasis

3M ESPE introduces its latest impression-taking breakthrough: the 3M ESPE Astringent Retraction Paste. Designed with an extra-fine tip that can be inserted right into the sulcus, the retraction capsule is the first gingival retraction system that delivers astringent retraction paste using common composite dispensers.

The time-savings enabled by the retraction capsule make it a convenient alternative to traditional gingival retraction methods such as retraction cord and other retraction pastes. Compared to retraction cords, the innovative system can cut up to half the time from the gingival retraction procedure, and is up to 30 percent faster than the leading retraction paste while effectively deflecting the marginal gingiva and providing long-lasting hemostasis.

3M ESPE developed the retraction capsule to give dentists a simple and time-saving solution for effective retraction. Shaped like a hummingbird's bill, the capsule's patented extra-fine tip is designed to actively open the sulcus and easily deliver the high-viscous astringent paste into the sulcus. And just as a hummingbird's bill has flexibility to allow more control, the capsule also has a flexible, soft-edge tip and an orientation ring, like a perio probe. Both of these features allow dentists more precise control and easy intra-oral handling.

The process to use the product is easy: the dental professional can simply fix the retraction capsule in a composite dispenser, then insert its tip into the sulcus and slowly inject the material. After two minutes, the retraction paste can be removed with an air-water spray. Each unit-dose retraction capsule contains 15 percent aluminum chloride, recently recognized by researchers as being as effective as epinephrine soaked cord in reducing the flow of sulcular fluid.1 The single-use capsule also helps dentists avoid problems caused by cross-contamination. Because it's disposable, there are fewer preparation and process steps than competitive pastes.

International field testing with more than 250 dentists has provided significant support for the product's ease of use. Testing with dentists who currently use retraction paste found that users appreciated the retraction capsule's easier application of retraction paste into the sulcus and better inter proximal access. Dentists who currently use gingival retraction cord were impressed by the retraction capsule's convenience, and also appreciated the lower risk of post hemorrhage when using the capsules versus retraction cord. Overall, 84 percent of field test participants stated they would recommend the product to their colleagues. Astringent Retraction paste capsules are suited for any situation where a temporary retraction of the marginal gingiva and a dry and clean sulcus are required, such as material-based and digital impression taking and preparation of Class II and V fillings.
