An evaluation of the effect of the adhesive luting on microleakage of the IPS empress crowns.

In an ongoing search for improved aesthetics, new materials and techniques are being developed and evaluated for clinical application; all-ceramic crown systems are among them. This paper presents an in vitro evaluation of the effect of dentin and porcelain bonding, with luting resin, on microleakage of porcelain crowns. Clinical application is discussed, and three cases are used to illustrate the procedure. The learning objective of this article is to enhance the knowledge of the more recent developments in dental materials and application techniques.
