Hard- and soft-tissue concepts for alveolar ridge preservations
Speaker: PD Dr. Ronald E. Jung, Switzerland
Every dentist is confronted on a daily base with the question: what to do with extraction sockets? Millions of extractions are going to be performed worldwide and no clear strategies and indications regarding ridge preservation are available. Strategies for handling of extraction sockets can either try to preserve hard and soft tissue or try to optimize hard and soft tissue by grafting procedures. Based on new techniques to evaluate volume changes over the time different therapies will be evaluated and qualified. The advantages and the limitations of different techniques will be discussed. Today’s possibilities to regenerate hard and soft tissues by means of soft tissue alternatives will be presented. Based on an overall comparison of the different techniques for hard and soft tissue preservation clinical concepts for various situations will be defined.

The management of soft tissues in post-extractive site and periodontal plastic surgery
Speaker: Dr. Daniele Cardaropoli, Italy
Treatment of gingival recessions is usually performed surgically according to the principles of GTR for mucogingival therapy. The use of coronally advanced flap (CAF) together with connective tissue graft (CTG) can produce predictable outcomes in terms of recession coverage, gain of keratinized tissue and improvement of gingival thickness. However, the graft harvest may have high morbidity resulting from the second surgical site, patient discomfort, post-surgical bleeding and limited supply of donor tissue. In the last years, alternative procedures to CTG have been evaluated to limit invasiveness and pain. After tooth extraction, bone resorption of varying amounts always occurs since the edentulous site of the alveolar process undergoes both qualitative and quantitative changes. The preservation of the ridge by grafting the post-extraction socket is able to compensate for physiological bone remodelling. Best techniques and choice of biomaterials used to achieve optimal ridge preservation will be discussed.
