An interventional study of Platelet rich fibrin and Placebo in Paresthesia, Anesthesia, Local and Neurosensory Disorder, sponsored by Shiraz University of Medical Sciences. Status unknown at 2 sites in Iran, Islamic Republic of. Open to participants aged 18 Years to 40 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2017-12-07.

Patients who have mandibular deformity and will undergo bilateral sagittal split osteotomy will be included in the study.One side of the osteotomies randomly will be considered as study group and another side as a control group.In the study group , platelet rich fibrin will be placed after osteotomy and before rigid fixation.In the control group, fixation will be done without Platelet-rich Fibrin (PRF).Neurosensory disturbance will be evaluated 6 and 12 months after surgeries.

Before starting the surgical procedure, 20 mL of venous blood will take and placed in a centrifuge for 12 minutes with 28000rpm. After centrifugation, the cap will be removed from each tube and they will be placed into a sterile rack L-PRF™. Fibrin matrix will prepare. The L-PRF™ will be removed from the tube. Then, the clot right beneath the red blood cell clot will be placed on the surface tray and covered. Five minutes will be waited before removing and using the fibrin matrix.Neurosensory disturbance will be evaluated in 6 and 12 months after osteotomies by two-point discrimination (TPD) test and pin tactile discrimination(PTD) tests.
Exclusion Criteria:
One side of osteotomies will be considered as a treatment arm (randomly) which Platelet rich fibrin will be used with rigid fixation
Biological: Platelet rich fibrin
In control site , placebo gel will be placed before rigid fixation
Biological: Placebo
Platelet rich fibrin will be prepared by taking 20 cc blood and centrifugation with 28000 rpm.
In control group , after spliting the osteotomy site before fixation a placebo gel will be placed
Two-point discrimination (TPD) test
Two point discrimination will be measured based on the distance of two points (mm)
Time frame: TPD will be assessed after 6 months
Two-point discrimination
Two point discrimination will be measured based on the distance of two points (mm)
Time frame: Two-point discrimination will be evaluated after12 months intervals
Plan to share: Undecided
