A detailed resource on periodontics, this volume addresses the full spectrum of periodontal issues. The book's coverage extends logically from the anatomy of the periodontium through to treatment options, and elucidates the relationship between periodontal and restorative dental therapies. The section dedicated to implants in the periodontally-compromised patient reflects the increasing importance of this form of oral rehabilitation. This section includes new chapters on implant placement in the aesthetic zone and issues related to supportive therapy in the implant patient. With an approximate 25 per cent increase in length, this fourth edition keeps pace with the level of interest and growth of research in periodontology. Chapters included in previous editions have been updated and many new chapters added, including modifying factors in periodontal disease, risk assessment, and genetics in relation to periodontitis.
