The physiological remodeling following tooth extraction may compromise the stability of removable dentures as well as the insertion of dental implants, thus increasing the need for demanding bone augmentation procedures. This preclinical animal study aims at histologically/ immunohistochemically and volumetrically evaluating the performance of differently conditioned (i.e. periodontally diseased, healthy) tooth roots serving as autografts for alveolar ridge augmentation procedures at deficient extraction sockets in a standardized rat model. Spontaneous extraction socket healing will serve as control. All extraction sockets will be covered with a free gingival graft harvested from the palate. This “socket sealing” technique aims at securing the position and stability of the tooth roots and/ or the blood clot within the extraction sockets of all groups investigated. This project will provide the fundamental basis for an alternative biological approach for the future clinical management of compromised extraction sockets.
