This book presents up-to-date information on promising indications for ultrasound in contemporary periodontics and implant therapy with the aim of assisting researchers and dental practitioners to use this novel imaging modality to advance research and patient care. Readers will find clear guidance on the application of ultrasound for evaluation of periodontal and peri-implant tissues. The mechanism of ultrasound imaging is explained in detail and compared to other imaging modalities. Furthermore, the role of ultrasound in the planning and execution of implant surgery and the assessment of implant stability is discussed. The book closes by considering the potential dental applications of functional ultrasound and volumetric ultrasound. This book will potentially be of high values for dental surgeons, periodontists, general dentists, orthodontists, dental hygienists, dental assistants, dental researchers and other practitioners, etc.

Hsun-Liang Chan, DDS, MS, is Clinical Associate Professor and Assistant Program Director of the Periodontics Graduate Program in the Department of Periodontics and Oral Medicine at the University of Michigan School of Dentistry, Ann Arbor, MI, USA. He earned his DDS from Taipei Medical University, Taiwan in 2003 and his MS/Certificate in Periodontics in 2011 from the University of Michigan School of Dentistry with a prestigious award, Sigurd P. Ramfjord Award for Excellence in Graduate Periodontics.  He received several other awards from the American Academy of Periodontology (AAP), including Fellowship to the Institute for Teaching & Learning (2011), Abram and Sylvia Chasens Teaching and Research Fellowship (2011), Nevins Teaching and Clinical Research Fellowship (2013), Outstanding Teaching and Mentoring in Periodontics (2015) and AAP Sunstar Innovation Award (2018).Dr. Chan limits his practice to periodontal and implant therapy. His main focuses in clinical research and patient care are development of innovative imaging technology, especially ultrasonography, minimally invasive regenerative approaches, e.g. microsurgery, and image-guided surgeries. To date he has authored approximately 100 peer-reviewed journal articles.
