[QUOTE="steves dental lab, post: 337201, member: 1954"] I think he is talking about the stone sticking to the teeth . He said it sometimes sticks to the, acrylic meaning its mostly sticking to the teeth. All the advice given is on the other side of the denture and below the teeth that is covered with stone not where the picking takes place ,except for the putty advice . He is talking about the stone sticking to teeth which is on the other side of any separator that's added . The putty is replacing the stone so that's why its coming out so clean . No monomer is passing through the putty and reaching the teeth . The only bad thing about the putty is if you pack the denture under pressure the acrylic could move or work between the putty and teeth .
