The aim of this article is to introduce and illustrate the "Teflon tape technique," which provides good lucidity in combination with excellent isolation of the working field. It is intended to serve as a supplement to the gold standard rubber dam for the adhesive working dental practitioner. Primarily, the Teflon tape technique (Teflon is a registered trademark, and not affiliated with Teflon tape) is particularly suitable for the adhesive cementation of restorations with very thin margins. It allows free access to subgingival areas with variable gingival retraction. Furthermore, this principle can also be applied to other indications, such as Class V restorations or deep core buildups. The technique described is therefore flexible and easy to use. This combination allows a fast integration of the Teflon tape technique into the daily workflow of the dental practitioner.
