Wax up technique

This video shows a wax up technique using a dipping pot. The wax up takes about 6 minutes per unit. A small bridge framework is waxed, sprued and invested.

I have never found a problem with investment cracking even though I don't apply a wax layer over the bar. I use 4mm Metrodent plastic sprues and Shera fina 2000 investment. These work a treat.

Fairplay......... you do your own investing and casting

I have just bought the Etkon system as well as already having Lava, so the future looks like having much less waxing for me!

I noticed you don't put any metal support for porcelain at the marginal ridges...or maybe it just appears that way on your video

Nice casting work.

Do you apply a layer of waxer to the plastic spreader bar?

Many plastic sprues tend to have a higher CTE than the wax, which tends to crack the investment during burnout. Obviously you arent having problems, perhaps this plastic is a specific type?

For me your method to made this brigde isn´t correct. The dental structures/morfology are too bad. just have a little bit details when it is needed more details to reproduce real dental structure

Very similar to methods of jewellery patterns I have made before!

I do my bridges the same way, and have great results as well
