Introduction: One of the recent grafting materi‌als is mineralized plasmatic matrix (MPM). It is an autologous blood product with high concentration of platelets and fibrin in addition with bone particles. Its fibrin combined with the bone particles and the grafting material can be shaped easily. MPM became favourable in improving treatment outcomes of dental implants due to the efficiency of bone formation.
Objectives: To compare clinically and radiologically the efficiency of MPM verses beta tricalcium phosphate in osseointegration in immediate placement of implant at mandibular molar area.
Materials and Methods: Randomized clinical trial done on sixteen patients, with strongly decayed mandibular molars. All patients separated into 2 equal groups: In group A, 8 immediate implants were placed in mandibular molars using MPM as graft in the peri implant gap and in group B, eight immediate implants were placed in mandibular molars using beta tricalcium phosphate as graft in the peri implant gap. Patients were clinically and radiologically evaluated for six months.
Results: Group A showed statistically higher mean implant stability, statistically higher bone density percent change and statistically lesser mean marginal bone loss after six months than beta tricalcium phosphate. For both groups, during the six months period, no significant difference in peri implants probing depth.
Conclusion: MPM enhances formation of bone in mandibular area, and provides better bone density, implant stability and less marginal bone loss compared to beta TCP.
