find a spot where the reline is separated from the denture and start drooping monomer slowly for 10-15 min most of it will peel out . f... the smell of the bur grinding that crap it is unbearable with 3 masks
I use a combination of the stippler which holds 3 of the round burs,#25 razor ( careful) and Permaliner by protech kit comes with 3 cutter burs that remove what’s leftover easily, if it’s thin the latter works great by itself. also keystone carries the Z bur which was made to remove silicone type materials.
