Is BTM a synthetic skin graft?
Excuse me, could you please clarify what you mean by "BTM"? Is it a specific product, acronym, or technology you're referring to in the context of synthetic skin grafts? As far as I'm aware, the term "BTM" isn't commonly associated with medical or surgical procedures, including synthetic skin grafts. Could you provide more context or detail about what you're asking, so I can give you an accurate answer?
