Effect of Local Application of Platelet-Rich Fibrin Scaffold Loaded With Simvastatin Versus Bone Powder on Peri-Implant Bone Changes
Effect of Local Application of Platelet-Rich Fibrin Scaffold Loaded With Simvastatin Versus Bone Powder on Peri-Implant Bone Changes
This study is conducted A- To investigate that PRF loaded with osteopromotive pharmacological drug can be a great aid in implant rehabilitation, and whether it could be a replacement for the other high price bone graft materials or not.
This will be done through:
B- Evaluate the effect of statins on osteoblasts activity and expression of various osteogenic products in vitro.
Twenty four patients requiring rehabilitation by immediate implantation in an extraction socket were recruited for this study. The Patients were divided into three groups (n=8), For the first group; immediately after extraction, PRF alone was added into the extraction socket prior to implant insertion. For the second group, PRF + 1.2mg Statin powder are inserted into the extraction site before implant insertion. For the third Group; PRF + Bone powder are inserted into the extraction site before implant insertion. A conebeam CT was used to evaluate the effect on bone changes and bone density around implant sites, for every patient in all implant groups immediately after the surgery and at follow-up time. In vitro experiment: isolation of human Adipose mesenchymal stem cells (hAd-MSCs), characterization and osteogenic differentiation will be done. The cells were divided into two groups one control group and the other statin group. Osteogenic markers were measured in both groups and statistical analysis performed
