Platelet rich fibrin membrane: An effective biological dressing for the regeneration of lip defects – A case report

The face is a highly esthetic zone. Any facial injuries if not treated in tiSme can cause disfigurement and have a detrimental effect on the quality of life of the individual. Many studies are done in the field of tissue engineering which involves the application of growth factors to regenerate the lost facial tissues for a better esthetic outcome. Platelet concentrates (PCs) are widely used in the medical field for the regeneration of soft tissue. Platelet-rich fibrin (PRF) is a second-generation PC that consists of a fibrin matrix polymerized in a tetra molecular structure that incorporates platelets, leucocytes, cytokines, and circulating stem cells. PRF membrane can be used as a biological dressing over maxillofacial wounds. This case report presents a unique way of regenerating the lost soft tissue of the lip by local application of PRF membranes as a biological dressing.
