Silane coupling agents belong to a class of organosilane compounds having at least two reactive groups of different types, bonded to the silicon atom in a molecule. One of the reactive groups (eg. methoxy, ethoxy and silanolic hydroxy groups) reacts with various inorganic materials such as glass, metals, silica, sand and the like, to form a chemical bond with the surface of the inorganic material, while the other of the reactive groups (e.g., vinyl, epoxy, methacryl, amino and mercapto groups) is reactive with various kinds of organic materials or synthetic resins to form a chemical bond. As a result of possessing these two types of reactive groups, silanes are capable of providing chemical bonding between an organic material and an inorganic material. This unique property of silanes is utilized for the surface treatment of glass fiber products, performance improvement of fiber-reinforced plastics by the direct admixture to the synthetic resin, improvement of paints and other coating materials and adhesives, modification of surface properties of inorganic fillers, surface priming of various substrate materials, etc. Dental materials offer a continuously challenging forum for silanes and silanes will play an essential role in material development This overview presents a description of silanes, their chemistry, properties, use and some of the main clinical experiences in dentistry. The majority of clinical results pointed to silanes playing a significant role in the adhesion process. |
