Aggressive periodontitis poses a great challenge to clinicians with regards to stabilization of periodontal disease and prosthetic rehabilitation. Implant placement in patients diagnosed with aggressive periodontitis is often considered "taboo" due to the multiple complicating factors of this disease and the rapid nature of destruction of the periodontal attachment apparatus. The preprosthetic implant site preparation is the most important, but most often overlooked procedure in implant dentistry. This book has been written with the sole aim of encouraging the implant practitioners in providing an esthetic and functioning dentition for such patients by performing the most valued step of pre-prosthetic site preparation to achieve fine quality and quantity of bone for implant placement.
