Retracto are polyester cords impregnated with aluminium chloride hexahydrate for the temporary retraction and haemostasis of the gingival margin. They are also available as non impregnated. The mechanical use of the retraction cord causes compression. The compression contracts the treated tissue and causes haemostasis.
The retraction cord is available in 2 versions: Retracto impregnated / non impregnated braided is slightly more compact and firmer than Retracto impregnated / non impregnated twisted and is preferable when increased retraction is required.
