Sandwich technique restoration in posterior teeth – case report.

Modern direct restorations of dental lesions with adhesive materials can be achieved through different working protocols. Among them, sandwich technique is one of the well-known procedures, especially for posterior area, in which two materials, usually glass ionomer cement and resin composite, are used together in order to obtain a monolithic dental structure, combining the properties of both materials and, thus, a superior result obtained. In this way, not only the longevity of restoration is improved, but also the tooth health and survival on dental arch are maintained. [ABSTRACT FROM AUTHOR]
