NCT03159338

Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Two-point discrimination (TPD) test

    Two point discrimination will be measured based on the distance of two points (mm)

    TPD will be assessed after 6 months

  • Two-point discrimination

    Two point discrimination will be measured based on the distance of two points (mm)

    Two-point discrimination will be evaluated after12 months intervals

Study Arms (2)

treatment group

ACTIVE COMPARATOR

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

Control group

PLACEBO COMPARATOR

In control site , placebo gel will be placed before rigid fixation

Biological: Placebo

Interventions

Platelet rich fibrin will be prepared by taking 20 cc blood and centrifugation with 28000 rpm.

treatment group
PlaceboBIOLOGICAL

In control group , after spliting the osteotomy site before fixation a placebo gel will be placed

Control group
