MAKING GREAT IMPRESSIONS: A Fast, Safe and Simple Retraction Technique Using Expasyl
Dr Christopher C.K. Ho، Australia
Expasyl is a paste-like material that is used for gingival retraction and haemostasis leaving the prepared field clean, retracted and dry ready for impressions or for other restorative procedures. This product is primarily composed of kaolin (a clay substance) and aluminum chloride (an astringent that controls gingival bleeding).
It is dispensed into the sulcus with a special delivery gun. It is thick and firm allowing the material to gently displace the gingival tissue. The haemostasis is achieved with the presence of the aluminum chloride. It creates a beautifully dry and clean sulcus that is ready for an impression or restorative procedure in a much shorter time than conventional techniques and is gentler to the soft tissues.
