Would you like to improve patient outcomes by learning to repair unsightly post-extraction bony defects with ridge preservation techniques?

You can achieve more predictable prosthetic and esthetic results for your patients through careful management of the extraction site following tooth removal. Through this unique continuing dental education course, you will gain practical experience with techniques and materials used in ridge preservation, a type of bone grafting that involves placing a regenerative bone graft and/or membrane into one or multiple tooth sockets to prevent bone loss and improve cosmetic results. Hands-on exercises on specially designed dental models will give you valuable experience with: 1) extraction site preparation, 2) bone graft and membrane selection and placement, and 3) closure of various types of defects. Don’t miss this opportunity to develop the knowledge and skills to enhance esthetic and post-operative outcomes for your patients. 


Through illustrated lectures and hands-on exercises you will learn how to:

  • determine the requirements for bone graft and membrane use—why, what, when.
  • evaluate the extraction site.
  • select the appropriate site preservation technique.
  • identify the different types of materials used for grafting.
  • select the appropriate grafting material(s) for the presenting defect.
  • perform site preservation and closure of various types of defects.
