Comparative analysis of two methods of socket preservation: A pilot study

Abstract

Objective. Volumetric changes of the residual alveolar ridge begin after tooth extraction. They are more pronounced in the vestibule-oral aspect than in the coronary-apical aspect. In order to preserve the volume of hard and soft tissues, several types of bone grafts, bone substitutes and biomaterials have been used. PRF (Platelet Rich Fibrin) as an autologous blood derivative has been used in recent years as a solo graft material or in combination with other graft materials. The aim of this study was clinical and radiological evaluation of two different methods of socket preservation. Methods. Two study groups of 10 subjects each, one with socket preservation with solo PRF and the other with PRF+xenograft. Dimensional changes after 4 and 6 months, density of the newly formed bone after 4 months with CBCT 3D (cone beam computed tomography) imaging technique, postoperative morbidity during the first 7 days after intervention were evaluated. Results. Statistical analysis confirmed lower bone resorption in the PRF+GRAFT test group compared to the PRF group. Better density of the newly formed bone was found in the PRF+GRAFT group and better ratio between the density in the socket and the density in the periapical region. Postoperative morbidity decreased in both groups. Conclusion. Recommendation for the use of PRF as an adjuvant with other grafts and substitutes, as well as a solo graft material.
