The management of the ridge alterations that take place following tooth extraction is of great interest for Implant Dentistry. The current presentation will describe a series of studies regarding the various ways to approach the post-extraction bone diminution. It will be demonstrated that the anatomy of the alveolar process influences the amount of post-extraction bone loss. The benefit of a minimally invasive tooth extraction for the socket healing will also be discussed. The use of ridge preservation, a clinical procedure that aims at preserving the ridge volume within the envelope existing at the time of extraction, and ridge augmentation, a procedure that aims at increasing the ridge volume beyond the skeletal envelope existing at the time of extraction, will be described. Clinical cases that illustrate the surgical technique and outcome of ridge preservation and augmentation procedures will be discussed.
“Soft tissue Grafting for improving Peri-implant health”
The lack of keratinized mucosa represents a challenge for the clinician. It may not only lead to esthetic but also biological problems. The current presentation will explain the fate of the keratinized tissue after tooth extraction, describe the peri-implant soft tissues and discuss the scientific evidence that addresses the effect of the lack of keratinized mucosa on the peri-implant health. Furthermore, clinical cases will be presented to describe the indication and surgical techniques for keratinized tissue augmentation around implants.
