[QUOTE="H.Ross, post: 204960, member: 15502"] Hello guys, I always do refractory models in two different ways. But I wanted to learn or adjust my method with your help. What do you suggest? 1- Pour the impression with stone, ditch the margins, duplicate it with silicone, then pour it with refractory. This method is fast and good for a maximum two unit veneers with minimal prep. 2- Pour the impression (only prep) and increase the height of stone, separate the stumps, ditch the margins, create anti rotation grooves, duplicate stumps with silicone, pour the silicone with refractory, put the refractory stumps back in impression, brush them with separator, pour impression with stumps attached using stone, Final model in picture This picture taken from Miladinov Milos page on Facebook [ATTACH=full]20863[/ATTACH] [/QUOTE]
