Hey all I'm new here but will get straight to the point.
Im tired of rocking bridges and have seemed to try everything with little luck. Let me give a quick detail of my technique. I use hot melted wax for initial application and hot melted wax for build up of copings. (I get absolutely perfect adaptation most of the time.) My waxer is set to 305 degrees all day. So for bridge wax up I'll wax up the copings add collars and trim margins then put back on model. Ill then wax in the pontics and finish. Now we check everything on solid model so ill now cut the bridge with a razor blade stick the wax pattern on the trimmed solid model and reattach it with duralay and ive also tried super glue. Many times it works. Many times it doesnt and ill end up with a tiny rock - and with very large bridges even though it seems great on the solid model theyll end up rocking after casting. I keep up on my water powder ratio's every day as well. My copings require very little work to get perfect fits. Oh I also most of the time use a direct spruing technique - For example a large plastic sprue with reservoir to pontic and wax leads coming from reservoir to abutments. Any suggestions? Im baffled.
