Evaluation of the Effectiveness of Odontogenic Grafts Obtained From Human Teeth on Bone Formation

Tooth extraction triggers a cascade of biological events mediated by the local inflammatory response following surgical intervention and by the loss of masticatory stimulation to the periodontium. These factors disrupt the homeostasis and structural integrity of the periodontal tissues. Following tooth loss, bone remodeling is initiated and continues for several months, with the majority of dimensional and morphological changes occurring within the first three months. This early alveolar bone resorption may compromise future implant placement and prosthetic rehabilitation.

Previous studies by Schmidt-Schultz and Schultz have demonstrated that biologically intact growth factors can be preserved within the collagenous extracellular matrix of ancient human bone and teeth. These findings suggest that stored dentin may retain biologically active growth factors and provide regenerative benefits comparable to those of freshly prepared dentin, while eliminating the need for simultaneous multiple surgical interventions. Moreover, the volume of particulate dentin exceeds twice the original root volume, allowing for the acquisition of sufficient graft material for clinical application.

Based on these biological and volumetric advantages, the use of autogenous stored mineralized dentin grafts (ASMDG) has emerged as a promising approach for alveolar socket preservation. ASMDG may contribute to limiting post-extraction alveolar ridge resorption and maintaining ridge dimensions during the critical early healing period.
