Adjunctive Use of Polynucleotide and Hyaluronic Acid-based Gel in Alveolar Preservation After Tooth Extraction

Alveolar ridge resorption after tooth extraction is a physiological process that continues throughout the patient's life due to the loss of the periodontal ligament and lack of mechanical stimulation. Alveolar ridge preservation (ARP) techniques aim to minimize dimensional changes in the ridge after tooth extraction. These techniques involve grafting the socket to fill the bed and/or sealing it with a biomaterial. Currently, there is a polynucleotide and hyaluronic acid-based gel (Regenfast®) on the market that has proven useful in treating residual periodontal defects. Hyaluronic acid-based gels also appear to enhance the regenerative potential of critical bone defects in both in-vitro studies on rats and clinical studies. Therefore, this study aims to evaluate the clinical and histological effects of polynucleotide and hyaluronic acid-based gel in alveolar preservation procedures.
