The answer lies in understanding what the under- lying goals and objectives are in conveying knowledge. A “true” teacher shares the gift of wisdom and experience without the expectation of receiving anything in return. It is this act of sharing in itself that yields fulfillment. In a dental world filled with both academic and clinical rivalry, it is unusual today to find a teacher who is not driven solely by the need to “self-promote” and to continually create opportunities to showcase his or her most successful treatment outcomes. It is with this in mind that Dr Raigrodski has written a book for our profession in which he teaches with no other reason than to share his knowledge with dentists who will greatly benefit from its content. This book is dedicated to providing a better understanding of the soft tissue–restorative interface and its influence on the final restorative result. It provides a simplified, well- organized, evidence-based, step-by-step approach to achieving esthetically pleasing restor- ative outcomes. To achieve a predictable soft tissue outcome around natural teeth or dental implants re- quires not only strict discipline in the clinical protocol but also a keen understanding and control of tooth contour and emergence profile. As this text illustrates—with superb detail and interdisciplinary treatment—the ultimate challenge lies in all of the fine details and nu- ances of crafting the provisional restorations as well as the definitive ones. As with all experienced teachers, Ariel has recognized the value of collaboration on a project of this magnitude. As you make your way through this textbook, you will begin to appreciate the level of commitment that the University of Washington graduate students have made with their own teaching contribution to the profession. There was great sensitivity to pre- senting information in a way that would be clearly understandable and most user-friendly. Soft Tissue Management: The Restorative Perspective will provide substantial and tangi- ble tools to restorative dentists, which will subsequently help them become more “com- plete” clinicians to their patients. As dentists become more capable of controlling the “soft tissue frame,” they will better be able to meet or exceed their patient’s ever-demanding expectations. Gerard J. Chiche Michael Cohen Augusta, Georgia Seattle, Washington vi Preface Ten years ago, I was invited to give a lecture on how to manage soft tissue from the per- spective of the restorative dentist. The request came from a group of dental practitioners who had been working comprehensively in an interdisciplinary manner to provide better care for their patients. However, many times they were frustrated with the definitive treat- ment outcome in terms of how the restorations blended with the soft tissue. I carefully developed the lecture, and with time it grew into a program, with inspiration from my gradu- ate students, colleagues, and mentors as well as my experience in private practice. It has culminated in this book. Soft tissue management from the restorative perspective is a topic that is fundamental for success in providing patients with esthetic and functional restorations and for improved pa- tient care. This is where the beautiful artistic work of the dental technician meets with the finish line of the tooth preparation and with the dentogingival complex at the soft tissue– restorative interface. Creating and managing the soft tissue frame is the essence of restor- ative dentistry, and it is a constant challenge for clinicians, regardless of the type of restora- tion (tooth borne or implant supported) being provided. In every step of restorative therapy, the soft tissue may be susceptible to trauma that may or may not be reversible and may adversely affect the desired esthetic outcome. Much has already been written on this topic from both research and clinical perspectives. The vision for this book, however, is to provide clinicians with evidence-based concepts that will guide them as technologies and materials in dentistry continue to evolve. The goal is to demystify clinical restorative procedures and help restorative dentists ensure better control of the soft tissue frame (also known as the pink esthetics) during all clinical steps of restorative therapy while enhancing a healthy and esthetic treatment outcome. Therefore, the book offers a simplified approach for soft tissue management during restorative therapy and practical tools that restorative dentists may apply in their daily practice. Writing this book provided me with a great opportunity to learn more and augment my knowledge and clinical skills. I can only hope that this book similarly provides restorative dentists with practical, tangible, and valuable tools based on sound scientific concepts that will help them in their everyday practice. Acknowledgments First, I would like to thank all the contributors to this book as well as all the faculty members at the University of Washington, especially Deans Martha J. Somerman, Timothy A. DeRouen, and Joel H. Berg. In addition, this book would not be possible without the inspiration and collaboration of my graduate students in the Graduate Prosthodontics program. I am also in debt to all the clinicians and dental technicians (including Kimiyo Sawyer and her team from Cusp Dental Laboratory) whose excel- lent work is depicted in the cases presented in this book (see page x). Carole Green and Jeff Meadows from the Graduate Prosthodontics clinic and my office manager, Paige Moody, have offered me significant support and assistance, for which I am grateful. Many thanks as well to Heather Bright from the Seattle Study Club and Michelle Butcher from the Graduate Prosthodontics program. I am also grateful for the education I received at the Hebrew University School of Dental Medicine in Jerusalem, Israel, and at Louisiana State University School of Dentistry. My deepest appreciation and gratitude go to my program director, Israel M. Finger, and my master research mentor, Shawky E. Mohamed, for their wisdom and guidance. Finally, I must express my eternal gratitude to Gerard J. Chiche, who continues to inspire me as an excellent teacher, superior clinician, and a genuine human being, and Michael Cohen, who has inspired me to write this book and continues to be a mentor, a friend, and a family. vii Contributors Matthew R.
