As more and more people today are choosing dental implants over traditional methods of tooth replacement, a corresponding rise in the number of individuals with post-implant complications can be expected. Consequently, the significance of treating conditions such as peri-implant infections is mounting. This book provides a clear and easily comprehensible description of periimplant tissue anatomy and structure as well as of the etiological and pathogenetic factors associated with peri-implantitis. Clinical features and current options for diagnosis of peri-implant disease (including radiological and microbiological procedures) are discussed in detail based on numerous case studies. Using a modular treatment approach placing special emphasis on clinical relevance, this book provides a comprehensive and critical introduction to non-surgical procedures, including laser therapy and implant surface decontamination, antimicrobial and antiphlogistic treatments, and surgical procedures, including resective and regenerative procedures as well as explantation.
