Five essential ele- ments contribute to this: 1. Conical connection to prevent microleakage. 2. Triple treated surface to optimise the transition from primary to secondary stability. 3. Platform switching to accommodate the biologic Principles of bone healing and augmentation To understand bone healing and the options for augmentation of complex defects, refer to the previ- ous publications.1–3 We also repeat essential knowl- edge of the previous article (implants 4/2013).
