About
This study aim to investigate the effect of albumin gel- and platelet- rich fibrin(Alb-PRF) combined with advanced platelet-rich fibrin (A-PRF) on alveolar ridge preservation by comparing alveolar ridge morphometric changes (hard and soft tissue), prospects and treatment complexity for placement of prosthetically guided dental implant, early oral wound healing outcomes evaluated by the Inflammatory Proliferative Remodeling Scale, and patient reported outcome measures, in Type I/II Diabetes Mellitus patient, versus spontaneous healing
Full description
Diabetes is a well-established risk factor for oral diseases that often lead to extractions and tooth loss in the population, while diabetic patients also have increased susceptibility to wound infections.
Albumin gel-platelet-rich fibrin (Alb-PRF) and advanced platelet-rich fibrin (A-PRF) are third-generation of platelet concentrates derived from a donor's blood by following a simple centrifugation protocol, heat treatment of platelet-poor plasma, and mixing of liquid-PRF from the same preparation.
This study proposes a novel alveolar ridge preservation technique based on the application of A-PRF inside the extraction socket to sustain the release of growth factors during the early wound healing phase, together with periosteum inhibition by overlaying an Alb-PRF membrane with slow biodegradation and space maintenance properties over the bone to reduce post-extraction alveolar ridge resorption.
