I made a new account for this post. I am on faculty at the MUSC college of dental medicine. I help run a surgery simulation lab for the dental students and residents using pig mandibles. Our traditional source can’t help us this year and we are looking for new sources. We need the whole mandibles with the soft tissues attached (lips and gums and whatnot). We will need approx 100 and will be paying for these.
Not sure of the price or what you may be willing to pay but IGA sells the whole head and many other grocery stores can get them if you request it. Maybe try Rizers pork and produce or some other butcher shops? Phone: (843) 866-2645
