The purpose of this book is to set out a simple yet rigorous protocol that can routinely be used to achieve satisfactory results for composite partial restorations. Inlays and onlays allow significant conservation of sound tooth structure without undermining the tooth’s mechanical and physical properties. Composite inlays offer two crucial properties: the opportunity for correction before cementation and, above all, long-term reparability.A multidisciplinary approach is of fundamental importance in a process that involves restorative, periodontal, and endodontic dentistry, which is an essential characteristic of indirect adhesive techniques in posterior sectors.
