This book was inadvertently published with the below error:

A complication in its broadest sense can be defined as an infrequent and unfavourable evolution of a medical/dental treatment or as a circumstance/difficulty that complicates the outcome in implant dentistry (ID)/tooth-preserving surgery (TPS).

Complications in ID can be classified as biological, associated with peri-implant tissues such as the mucosa and alveolar bone, and hardware-related complications referring to the implant itself as well as prosthetic components (Braegger and Heitz-Mayfield 2015). Complications associated with dental implants can lead to implant failure and to its l...
