EVALUATION OF MINERALIZED PLASMATIC MATRIX AS A GRAFTING MATERIAL VERSUS BETA TRICALCIUM PHOSPHATE IN IMMEDIATE IMPLANT PLACEMENT OF MANDIBULAR MOLARS (A RANDOMIZED CONTROLLED CLINICAL TRIAL)

INTRODUCTION: One of the recent grafting materials is mineralized plasmatic matrix (MPM). It is an autologous blood product with a high concentration of platelets and fibrin in addition to 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 versus Beta-Tricalcium phosphate (β-TCP) in osseointegration during immediate placement of implant at the mandibular molar area. MATERIALS AND METHODS: Randomized clinical trial done on sixteen patients, with strongly decayed mandibular molars. All patients were divided into 2 equal groups: In group A, 8 immediate implants were placed in mandibular molars using MPM as a graft in the peri-implant gap. While in group B, eight immediate implants were placed in mandibular molars using β-TCP as a graft in the peri-implant gap. Bone density, marginal bone loss, implant stability and peri-implant probing depth were evaluated clinically and radiologically after 6 months for all patients. RESULTS: Group A showed statistically higher mean implant stability and bone density percent change after six months than group B. However the mean marginal bone loss was statistically lower. For both groups, during the six months follow up period, there was no significant difference regarding the peri-implant 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 β-TCP.
