About Lynch Biologics
Lynch Biologics is a regenerative medicine and tissue engineering company supplying advanced biotechnology products that promote healing and tissue regeneration spearheaded by GEM 21S®, and other widely used regenerative products, for periodontal and oral and maxillofacial indications. Their products have been used to help millions of patients regenerate lost bone and soft tissues and continue to be among the most popular grafting products with our dental colleagues.

GEM 21S® Growth-factor Enhanced Matrix was developed utilizing innovative tissue engineering principles which combine a bioactive protein (highly purified recombinant human platelet-derived growth factor, rhPDGF-BB) with an osteoconductive matrix (beta tricalcium phosphate, ß-TCP).

This completely synthetic grafting system is engineered to stimulate wound healing and bone regeneration when implanted in the body by triggering a cascade of molecular events that continues on even after the implanted rhPDGF-BB is gone.
