Soft tissue closure of extraction sites: A pilot study comparing composite grafts for ridge preservation
MetadataShow full item record
Aim: This clinical pilot study compared the effects of the use of four composite treatment methods on soft tissue closure/healing in human extraction sockets. The effects of platelet-rich fibrin (PRF)-calcium sulfate hemihydrate (CSH), platelet-rich plasma (PRP)-CSH, a resorbable collagen dressing (RCD), or no grafting material on the socket closure were compared. Materials and Methods: This was a randomized, controlled study with a blinded parallel design (n=23). Patients with a hopeless tooth were randomly assigned to one of the four treatment groups. Socket measurements were obtained immediately after extraction and treatment, and after 10, 21 and 28 days. Results: There was a significant decrease in the total area of the extraction sockets in each group at all time points. Comparisons between groups did not show any significant differences in the rate of soft tissue closure (p>0.05) at any time point. Conclusion: Extraction with ridge preservation using PRF-CSH or PRP-CSH did not result in a significant effect on soft tissue closure compared to using a resorbable collagen dressing or not using any graft material.
