It has taken me two years to write this book. I have gone through many references and also refer live cases of peri-implantitis and clinically determine the soft and hard tissue changes during the process. I'd like to help young practitioners who came across such cases in day in and day out. Guidance is required before any novel deed. My mentors guided me through this book and showed me a path to enlighten you in the path of clinical periodontology. Ok then go and buy it.
