Abstract
The purpose of this study was to investigate the effect of posterior maxillary ridge augmentation using mineralized plasmatic matrix versus autogenous bone graft on implant body stability and bone gain in a randomized clinical trial.Twenty implants were placed in eight sinuses with a defective edentulous posterior maxillary ridge. After diagnosis of each case clinically and radio graphically, patients were randomly assigned into two equal groups of 3 patients each. After implant placement, the ridges assigned to the study group received MPM{u2013} prepared by centrifugation of patient{u2019}s blood- mixed with autogenous bone graft; while ridges in the control group received the gold standard of particulate autogenous bone graft.Implant stability was assessed in ISQ unit by Osstell, and Vertical bone height was assessed by CBCT at 4 months. All demographic data and ISQ scores and CBCT measurements were collected and statistically analyzed. Results showed that, there was a statistically significant increase in implant stability, and vertical bone height after 4 months in both groups (P < 0.05). The mean value of ISQ scores, vertical bone height was not statistically different between both groups neither at 4 nor at 9 months (P > 0.05). The mean Osstell gain, bone height in the study group was significantly higher than those in the control group (P < 0.05)
