[QUOTE="desertfox384, post: 21687, member: 1501"] What do you all use for your pontics? I'm taking a string of 12 gauge spool wax and filling in pontic areas. Ive had a few more bridges rocking recently, still trying to figure out what is going on. Most of them do not have any kind of massive rock its usually a tiny tiny lift on the distal margin. I am generally waxing slow (i think) adding small amounts at a time (adding a dab of sticky wax to connectors then waiting 3 -4 minutes or so to cool) but when you have a huge pontic or need to wax a big case in a rush I cant seem to find a way around waxing quickly and not getting big rocks. I had a case the other day it was a 4 unit bridge with a big pontic, 3 metal occlusal and a full cast molar 12-15. Waxed it twice - First time i went slow a careful and it came out with a rock, pulling up on the distal of 15. Ok so rewaxed this time quicker since its due date is creeping up and i noticed a rock on the working model in wax. Sooo i cut it waited a few minutes to cool and reattached slowly and the exact rock came back time and time again so i finally cut it and attached it with glue. Rock was gone in wax, I attach sprue leads (8 ga on this big one but usually 12ga) slowly attach sprues to preformed runner bar just like lab guys in the picture. In metal rock was back. I find myself wanting to pull my hair out again! I thought i had this problem solved and cant figure out what has changed. [/QUOTE]
