Use of mineralized dentin graft in augmentation of different indication areas in the jaw bones

Introduction. Extracted teeth are still considered clinical waste and therefore are being discarded. It is evident that obtained and prepared autogenous dentin graft (ADG) may be used for guided bone regeneration (GBR) due to its similar biochemical characteristics to human bone. The aim was to present a novel procedure in a clinical setting that employs freshly extracted teeth that are processed into a bacteria-free particulate dentin, and then grafted immediately into the extraction sites or bone deffects. Monitoring the clinical and radiological parameters (vertical and horizontal dimensional changes on the alveolar ridge and vertical dimension of intrabony defects at the distal aspect of the second molar after extraction of third molar) for a period of 6 months, proved rapid healing capacity of ADG on the bone and soft tissue structures in the jawbones. Material and methods. Clinical measurements were performed using a questionnaire for monitoring the postoperative clinical manifestation, bone measuring calipers for measuring horizontal changes of the alveolar ridge and graduated probe for measuring vertical dimensional changes, also paraclinical-radiological examinations to follow-up bone density. Results. During the follow up period of six months, clinical measurements of post-extraction dimensional changes of the alveolar ridges showed minimal horizontal and vertical bone resorption with preserved alveolar ridge volume, with an accelerated bone regenerative process without special postoperative complications. Conclusion. Dentin particulate grafted immediately after extractions should be considered as gold standard due to its osteogenetic, osteoinductive and osteoconductive effects on bone tissue regeneration. With the use of mineralized dentin matrix we get maximum utilization of our own biological potential without the use of other artificial graft materials.
