Evaluation of thermally treated platelet-rich fibrin effectiveness in maintaining alveolar dimensions after extraction.: a randomized clinical study

After dental extraction, the alveolar bone begins to absorb and remodel itself as an adaptation to this change and the bone loss is greater in the horizontal direction and at the expense of the vestibular side of the alveolar ridge and clearly in the first three months after extraction, While the vertical resorption of the alveolar ridge is clearly in the first year after extraction and continues at a slower rate. Preserving the dimensions of the alveolar bone, restoring bone loss and improving bone density are necessary criteria not only for cosmetic aspects, but also for functionality and prosthetic aspects. Evaluation of the effectiveness of the use of Alb-PRF in maintaining the dimensions of the socket through a qualitative assessment of the bone formed using CBCT, as well as the vertical and horizontal dimensions of the alveolar bone. The study was conducted on 10 patients in need of a symmetrical tooth extraction, where the procedure was carried out for a tooth on one side without taking any subsequent action. On the opposite side, the socket was filled with an Alb-PRF. After a 3-month observation, it was found that the use of an Alb-PRF contributed to a significant improvement in the radial bone density values, in addition to reducing the bone absorption rates on the side of the Alb-PRF application. The use of Alb-PRF after extraction showed very good results in improving bone density during a 3-month observation period and improvement in the vestibular, lingual/palatal and transverse dimensions of the alveolar bone.
