Biomechanical Stability of Dental Implants in Augmented Maxillary Sites: Results of a Randomized Clinical Study with Four Different Biomaterials and PRF and a Biological View on Guided Bone Regeneration

Figure 10

(a) Preparation of PRF to be applied to pure bTCP in situ hardening biomaterial when randomly assigned. The PRF-clots will be compressed to form an elastic membrane and the expressed liquid aspirated with a sterile syringe for later washout of the “Biolinker” to harden the biomaterial to a bone-block-like graft. By this procedure active angiogenic and osteoblast stimulating cells are perfused inside the hardened porous biomaterial block. (b) Torque measurement in 1 Ncm-steps with the Implantcenter II, implant motor.
