PRESERVATION OF DISTAL BONE DEFECT AFTER SURGICAL EXTRACTION OF IMPACTED THIRD MOLAR

Extracted teeth are still considered a clinical waste and therefore being discarded. It is evident that obtained and prepared autogenous dentin graft (ADG) may be used for guided bone regeneration (GBR) because of similar biochemical characteristics to human bone. Aim: 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 extraction sites or bone deffects. Monitoring the clinical and radiological parameters in the postextraction defects of the alveolar ridges for a period of 6 months, proving the rapid healing capacity of ADG on the bonе and soft tissue structures in the jaw bones. Methods: Clinical measurements were performed using a questionnaire for monitoring the postoperative clinical manifestation, bone measuring calipers and for measuring the horizontal changes of the alveolar ridge and a graduated probe for measuring vertical dimensional changes, also paraclinical-radiological examinations to follow-up bone density. Results: During the follow period of six months, clinical measurements of post-extraction dimensional changes of the alveolar ridges shows 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 the gold standard due to its osteogenetic, osteoinductive and osteoconductive effects on bone tissue regeneration.
