SUG2009 – Lower endodontic arch w/ tooth #19, 20 and 28 are anatomically rooted and have the canals in place. Below the teeth there is a silicone lesion on the root tip as well. We also encased a small nylon thread right below the lesion to simulate a facial nerve. The model is incorporated with the nerve bundle below #19 and #20. The lesion can be removed and the ginigiva can be sutured back into place as well.
