Abstract:
Objective: Adequate alveolar ridge is needed for a successful implant placement to attain predictable long-term functioning and an esthetic treatment outcome. Various bone graft materials such as platelet-rich fibrin (PRF) and mineralized plasmatic matrix (MPM) are widely used in oral and maxillofacial surgery to stimulate a new bone tissue formation and accelerate healing. So, this study aimed to evaluate and compare the effect of (PRF) and (MPM) grafting materials in alveolar socket after extraction using cone beam computed tomography (CBCT) imaging to evaluated bone density, bone height and bone width.
Patients and methods: Twenty patients with permanent tooth indicated for extraction were collected from outpatient clinic in the Faculty of Dentistry, Al-Azhar University (boys- Cairo). The patients were divided randomly into two groups: study group, where ten patients' sockets were filled with mineralized plasmatic matrix (MPM) and control group where ten patients socket filled with platelet-rich fiber (PRF).​
Results: The results of this study showed an increase in bone density in the study group, in comparison according to height and width, both groups showed statistically significant decrease in bone height and width, but the study group show lower decrease in bone height and width than the control group.
Conclusion: The bone graft mixed with platelet has a superior biological effect on bone regeneration. Using MPM in socket preservation has a better radiological evidence to bone formation than PRF alone.
