Soft denture liners and tissue conditioners have been used in dental works for several decades. They can be defined as soft, resilient, elastic materials, which from a cushioned layer between the hard denture base and the oral mucosa. They are broadly divided into two groups of materials. The first group is the temporary soft materials which includes tissue conditioners. They are typically based on poly (ethyl methacrylate), an aromatic ester and ethyl alcohol. The second group includes the semipermanent soft lining materials based on silicone rubber or acrylic resin. Their useful properties have been studied and improved in many researches. This review describes their history, important properties, indications in use and also some recently related researches about force absorption and distribution to the underlining structure.
