After a tooth extraction both hard and soft tissues undergo dimensional changes. The use of a
ridge preservation technique at the moment of the tooth extraction could help could help to prevent the
volume loss, thus simplifying the subsequent prosthetic and/or implant therapy. Some studies were conducted
in order to examine the biomaterials and the surgical technique used for ridge preservation procedures.
Clinical, histological, volumetric and molecular outcomes were registered and analyzed in different
studies, in order to comprehend the biological events and the consequences of a socket preservation
procedure and to allow the clinician to make the correct choice.
