Titanium-Prepared Platelet Rich Fibrin in the Sinus Lifting Procedure

Blood samples were collected from the each participant's arm in the test group by 20 ml syringe and then was transferred into 10ml grade IV titanium tube without anticoagulant. After centrifugation of blood samples (2800 rpm, 12 minutes) at room temperature, the T-PRF clot was removed from the tubes with sterile tweezers. 6 blood tubes were collected for a sinus floor elevation/lifting operation and 6 T-PRFs were prepared for each participant.

After careful elevation of the schneiderian membrane without perforation, allograft was only used for augmentation of the sinus floor in the control group.
