What is the Best Way to Make An Emax Inlay?

The only way I know to accurately finish an emax inlay is to:

1) Wax up inlay over a lubricated die with die spacer, make a sharpened sprue connected to the inside of your wax up

2) Invest with a ratio allowing for a slightly looser fit than your crowns

3) Carefully devest and fit using a fit marker

4) Adjust margins with a silicone, fit, adjust contacts, smoothen with silicone

5) Glaze and stain
