Clinical Evaluation of Platelet Rich Fibrin Versus Subepithelial Connective Tissue Graft for Soft Tissue Augmentation

Soft tissue biotype is a critical factor for success of implant in the esthetic zone . Different soft tissue augmentation techniques have been employed to increase soft tissue thickness such as: autogenous grafts, allografts, xenografts and living cellular construct (LCC). Studies showed that, allografts and xenografts were inferior when compared with autogenous graft . However, few studies were conducted to evaluate the efficacy of soft tissue augmentation with platelet rich fibrin in order to overcome the patient morbidity with SCTG.
