Abstract
Rubber dam application has become an essential part of restorative dentistry. In late 2019, dentistry faced a new challenge with the COVID-19 pandemic and therefore, the implementation of extra isolation methods became crucial. This article introduces a classification of dental floss ties used with a rubber dam, including the "simple" ties that are subdivided into traditional ties, single-loop self-ligating ties and double-loop self-ligating ties, and a new state-of-the-art design. The "compound tie" design incorporates a combination of one or more subdivisions of the simple ties. This new design may provide better isolation and more consistent gingival tissue retraction. Furthermore, due to the advanced technique applied, the tie will offer improved stability and prevent the sheet from sliding over the dental floss tie from all surfaces.
