ABSTRACT
Aim: To Study the effect of mineralized plasmatic matrix(MPM) for 3-dimensional augmentation of anterior maxillary ridge deficiency.
Materials and Methods: Ridge augmentation was performed on 10 patients suffering horizontal and vertical bone loss in anterior maxilla using MPM covered by PRF membrane. Implant placement was done in grafted areas in second stage surgery. Grafted areas were evaluated preoperatively and post-operatively and after 6 months using CBCT.
Results: The apical and middle parts of the graft in horizontal levels remained without loss at the study intervals while coronal parts at horizontal level of the graft was lost and showed also native bone loss.
All cases showed statistically significant (P=0.05) bone loss in apical width value. There were a median decrease in point 1 (-1.205 mm) and in point 2 (-1.485 mm). In middle width median bone loss decrease in point one by (-3.15mm) and in point 2 (-2.68mm). In crestal width there were median decrease in bone in point one by (-2.425mm) and in point 2 (-1.95mm). All cases showed statistically significant bone loss in height with a median value of (-1.045 mm) at point 1 and median value of (-1.145 mm) at point 2.
Conclusion: Using MPM covered with PRF membrane only is not a siutable in augmentation of vertical and horizontal maxillary alveolar ridge augmentation. Using space maintainance, avoiding removable appliances and simultaneous or at least implant placement within 4 months after MPM insertion are keyfactors in success of MPM.
