Ridge defects are a very common finding after tooth extraction. Recent literature has shown that the pattern of bone and soft tissue remodeling can obtain up to 50% of the original volume. Many different surgical approaches have been proposed over the years to correct ridge defects, but the results have often been inconsistent or difficult to reproduce on a daily basis.
For some time, surgeons have relied on the guided bone regeneration (GBR) technique, taking advantage of a barrier membrane to protect the blood clot, combined with different combinations of autogenous bone and bone grafts from various sources. If some kind of understanding has been reached and certain guidelines adopted for the treatment of horizontal defects, those for tridimensional and vertical defects still present a challenge.
About a decade ago, a new biomaterial became available on the market - a membrane made of collagenated equine bone called cortical lamina - which provided to be reliable and easy to handle for both horizontal and vertical defects.

Dr. Rossi graduated in dentistry with honors in Genova and then specialized in Periodontology at Boston University Graduate School of Dental Medicine in 1992. He received the M.Sc.D. in Periodontology with a publication in the Journal of Periodontology.
He has been doing research in the field of guided tissue regeneration with different groups. He has been a professor in the departments of Periodontology in different universities (Genova, Padova, Pisa, Chieti, Roma) and is a professor at the Master in Periodontology program at the University of Roma 'Sapienza since 2000.
He is a member of the Italian Society of Perio (SidP), International member of the American Academy of Periodontology and an active member of the Italian Society of Esthetic Dentistry (IAED).
Dr. Rossi is a national and international speaker and an author of publications on peer reviewed magazines. He is also a co- author of the book Bone Biomaterials and Beyond, having particularly contributed to the chapters on guided tissue regeneration.
