Comparison of CTG and T-PRF on Peri-Implant Soft Tissue

A total of 40 ml blood sample was collected from the antecubital vein of the patients' right or left arms with 10 ml injectors. 40 ml blood was transferred to a grade-IV titanium tube for the T-PRF group. The titanium tubes containing the blood samples were instantly centrifuged in a tabletop centrifuge at room temperature. The blood samples of the T-PRF group were centrifuged clockwise at 2700 RPM for 20 minutes. Subsequent to the centrifugation process, the clots of the T-PRF group were removed from the tubes with sterile tweezers, separated from the RBC base with scissors, and left for over 20 minutes on sterile woven gauze to release the serum slowly from the collected clots. The implants were placed in thin tissues, and the thickness of the thin tissues was simultaneously increased with T-PRF.

The implants were placed in thin tissues, and the thickness of the thin tissues was simultaneously increased with CTG. Autogenous connective tissue graft was harvested according to a single incision technique.
