Tooth extraction procedure initiates a number of physiological processes in order for the created wound to heal. Bone resorption, being one of the consequences of the aforementioned processes, compromises prosthodontic rehabilitation of the patient due to the reduction in the dimensions of the alveolar ridge, particularly in implant-prosthetic therapy. In the case where there is not enough bone volume at the implantation site, the alveolar ridge needs to be augmented. It is possible to prevent a more significant reduction of the alveolar ridge through the socket preservation procedure. Shortly after tooth extraction, the post-extraction socket is filled with augmentation material. Autografts, allografts, xenografts, and alloplasts are used for this purpose. Motivated by the similarity between bone tissue and hard dental tissue, researchers considered dentin, in the form of autologous tooth dentin graft, as the alveolar bone augmentation material. Both the alveolar bone and teeth share the same embryological origin, the cranial neural crest. Moreover, dentin tissue is a hard dental tissue, very similar in composition to bone tissue. Autologous dentin graft is obtained by grinding the tooth into dentin particles and chemically processing them. Use cases of dentin graft range from socket preservation techniques to bone augmentation in sinuses and bone defects. Among its properties are osteoinduction, osteoconduction, progressive resorption, and replacement by bone tissue. Besides being bioactive, it is also biocompatible. It performs without eliciting an immune response, a foreign material reaction, or infection. Research shows promising results using dentin graft for augmentation in terms of alveolar ridge preservation and implant stability.
