Advanced Layering with Composites, Part II: Class IV and Class III Restorations: Why Can They Be So Unpredictable?

Course overview

Following Part I, Part II will help clinicians understand difficult direct restorations, such as Class IVs and Class IIIs, in order to treat them more efficiently. The optical phenomena of light interaction between the margin of dental enamel and composite will be thoroughly explained, allowing clinicians to prevent and treat the dreaded glass effect among other problems usually faced in that region. In addition, an overview of secondary optical phenomena, such as opalescence and fluorescence and the importance they play in the esthetic zone, will be discussed.
