For over 45 years, 3M ESPE has been leading the way in the field of dental impressioning. Now the innovative Retraction Capsule sets another milestone: it is a simple and effective means of gingival retraction.

  • Easy sulcus access and effective opening due to the capsule’s fine tip
  • Effective gingival deflection, clean and dry sulcus area, plus lasting and robust haemostasis
  • Convenient and time-saving procedure: 50% faster than using cords* (*Source: Field test with 227 dentists worldwide in 2010 and 2011)

"With the new 3M™ ESPE™ Astringent Retraction Product I was most impressed with the ease-of-use, unit-dose, application system and the efficiency"
Dr. Nicola, Italy (participant of the worldwide user field test)

The Dental Advisor is recommending 3M ESPE Astringent Retraction Paste for digital and traditional impression taking.

General advantages:

  • Enables a clean, dry sulcus and a long-lasting robust haemostasis
  • Effectively opens the sulcus

Versus cords:

  • Easy and time-saving retraction process: 50% faster (Global field test with 227 dentists, internal data available on request)
  • Lower risk of bleeding / haemorrhage after removal (Global field test with 227 dentists, internal data available on request)
  • Gentle on tissue for increased patient comfort

Versus competing pastes:

  • Easier application into the sulcus and better interproximal access due to capsule’s fine tip (Global field test with 227 dentists, internal data available on request)
  • More hygienic application, avoiding potential for problems caused by cross-contamination(unit-dose)

Indications

3M™ ESPE™ Astringent Retraction Paste is indicated for the temporary retraction of the marginal gingiva to provide a dry sulcus when the periodontium is healthy, such as:

  • taking impressions (material based or digital)
  • preparation of temporary casts
  • preparation of class II and V fillings

The product must not be used in patients suffering from a diseased periodontium, open furcations, or exposed bone.

Frequently Asked Questions

For how long can the paste be left in the sulcus?

Typically, the paste should be left in the sulcus for a minimum of 2 minutes to achieve good retraction results. If a hemostatic device is applied for a too long time it may exert unwanted negative effects on the tissue health. Therefore, the hemostatic retraction paste must be rinsed off completely after this time.

How long can one store the capsule outside of the blister?

The capsule should be taken out of the blister prior to application. It should not be stored outside the blister.

How many teeth can be treated with one capsule?

The content of one unit-dose capsule is sufficient to treat up to 3 teeth. The capsules are for single use and must not be used on more than one patient.

What is the orientation ring for?

The orientation ring corresponds in size and position to the perio probe. It is a feature for more precise and easy intra-oral handling.

Why is there a lower risk of bleeding/post haemorrhage than with cords?

Cords consist of small fibres that may be incorporated in the coagulum. When the cord is removed the wound might be opened again.
The paste is washed off by air-water spray and suction resulting in a clean and dry sulcus area.

How can one judge if the retraction effect is sufficient?

The preparation margin should be clearly visible in the impression.
The amount of excessive impression material (‘flash’) that covers sulcular areas below the preparation margin is not important.

Does the 3M™ ESPE™ Astringent Retraction Paste influence the setting of impression materials?

As with all astringents, the 3M™ ESPE™ Astringent Retraction Paste may inhibit the setting of A-silicones (VPS) and Polyethers. The paste must be completely rinsed off with air-water spray and suction prior to impression taking.
