Session II: Bone Preservation for Compromised Extraction Sites


Site Development for Implant Placement: Concepts, Procedures, and Techniques


Sonia S. Leziy
Friday, June 7
3:30 pm - 4:30 pm
Grand Ballroom (Salon E, F)

It is well established that tooth extraction impacts the dimensions of the alveolar ridge. This reduction largely affects the buccal aspect of the extraction site, although ridge height changes also can be significant in the case of multiple adjacent extractions. These changes can negatively impact the esthetic outcome of implant treatment and increase the complexity of reconstructive surgery. Clinicians continue to seek treatment approaches to minimize or ideally prevent bone loss following tooth loss; these include ridge enhancement with orthodontic site development, tissue contour support with ridge preservation protocols, and surgical protocols that take advantage of anatomy at the time of extraction coupled with restorative techniques to support soft tissues and seal the extraction wound. This presentation will explore current clinical strategies that can minimize dimensional tissue changes in immediate and delayed implant placement procedures.

Dr Leziy is a member of the editorial boards for several journals, including Spectrum Dialogue, Teamwork, and the Journal of Esthetic and Restorative Dentistry. She has published extensively on implant esthetics and surgical protocols and contributed to the textbook Interdisciplinary Treatment Planning: Principles, Design, Implementation (Quintessence, 2008). Dr Leziy lectures internationally on the subject of implants and advanced esthetics/periodontal surgery. She maintains a full-time private practice in the Imperio Group Dental Health Specialists with Dr Brahm Miller and Dr Priscilla Walsh. She is also a Fellow of both the Royal College of Dentists of Canada and the International Congress of Oral Implantologists and a member of the British Columbia Society of Periodontists, the Canadian Academy of Periodontists, the American Academy of Periodontists, and the American Academy of Esthetic Dentistry.
