Objective: To assess the effect of posterior mandibular ridge augmentation using mineralized plasmatic matrix versus autogenous bone graft on implant body stability: a randomized clinical trial comparative study. Materials and Methods: Twenty implants were placed in eight patients with defective edentulous posterior mandibular ridge. After diagnosis of each case clinically and radiographically, patients were randomly assigned into two equal groups of 4 patients each. After implant placement, the ridges assigned to the study group received MPM {u2013} prepared by centrifugation of patient{u2018}s blood- mixed with autogenous bone graft; while ridges in the control group received the gold standard of particulate aurogenous bone graft with high-density PTFE membrane. Implant stability was assessed in ISQ unit by Osstell, and Vertical bone height was assessed by CBCT at 0 and 6 months. All demographic data and ISQ scores and CBCT measurements were collected and statistically analyzed. Results: Results showed that, there was a statistically significant increase in implant stability, and vertical bone height after 6 months in both groups (P < 0.05). The mean value of ISQ scores, buccal and lingual vertical bone height in was not statistical different between both groups neither at 0 nor at 6 months (P > 0.05). The mean Osstell gain, buccal, and lingual bone height in the study group was significantly higher than that in the control group (P < 0.05). Conclusion: The results suggest that both techniques can be used to improve implant stability. The use of MPM in osseous regeneration and implant therapy have a positive impact in the outcome of the grafting surgery. It eases and enhances the delivery and homogenization of the grafting materials
