Session II: Bone Preservation for Compromised Extraction Sites


How To Preserve the Ridge: A Key Question in Clinical Practice


Christoph H. F. Hämmerle
Friday, June 7
8:15 am - 9:15 am
Grand Ballroom (Salon E, F)

A very large number of teeth are extracted in dental practices every day. The question for every dentist is how to best deal with an extraction socket. No clearly defined strategies regarding ridge preservation are presently available, and various techniques for handling extraction sockets have recently been published showing controversial data. Through the use of newly developed methods to quantitatively assess volume changes of the ridge, this presentation will evaluate the advantages and disadvantages of these techniques. Future possibilities will be presented for regeneration of hard and soft tissues of the ridge applying bioactive molecules. Novel carriers and matrices allow for reduction in the normal dosage of growth factors and more widespread use of this technology in daily practice. An algorithm will be provided on how to best deal with various clinical situations regarding hard and soft tissue preservation of the ridge.
