Özet

This randomized controlled clinical trial evaluated the effect of mineralized plasmatic matrix (MPM), comprised of synthetic graft and platelet concentrates, on new bone formation and volume stability over time in maxillary sinus lifting (MSL). Unilateral MSL was performed in 20 patients with either beta-tricalcium phosphate (beta-TCP) or MPM grafts (10 sinuses each). Six months postsurgery, specimens were obtained with a trephine bur prior to implant placement in 39 cases. Volumetric changes in sinus augmentation were analyzed between 1 week (T-I) and 6 months (T-II) postsurgery. Histomorphometric and histological analyses of biopsy samples revealed mean new bone percentages of 35.40% +/- 9.09% and 26.92% +/- 7.26% and residual graft particle areas of 23.13% +/- 6.16% and 32.25% +/- 8.48% in the MPM and beta-TCP groups, respectively (p < 0.05). The mean soft-tissue areas in the MPM and beta-TCP groups were 41.48% +/- 8.41% and 40.83% +/- 8.86%, respectively (p > 0.05). Graft reductions between baseline and 6-months postprocedure in the beta-TCP and MPM groups were 17.12% +/- 13.55% and 14.41% +/- 12.87%, respectively, with significant graft volume reduction observed in both groups (p < 0.05) while there is no significant difference between MPM and beta-TCP groups (p > 0.05). Thus, MPM, representing growth factors in a fibrin network, increases new bone formation and has acceptable volume stability in MSL procedures
