<![CDATA[Siloranes are a class of composites introduced in dentistry, introduced by Weinmann et al in 2005. Theterm silorane is derived from siloxane and oxirane. The combined form of these two chemical compoundsforms siloranes, which are biocompatible and hydrophobic in nature. The polymerization mechanism ofsilorane composites is described as a cationic ring opening polymerization reaction that causes opening andexpansion of the polymeric chain. This reduces the volumetric shrinkage when compared to methacrylatebased composites. This article highlights the composition and properties of silorane composites.]]>
