I was very pleased with both results as they give you 4 samples. As far as I know the laser is for the N.P. only. Someone correct me if I'm wrong. Spend time in making sure all undercuts are not present and the laser copings are sweet. What I haven't found out yet is how are the laser copings holding up long term. Is there a bonding issue? I just don't know but I would like to see some studies on this. The induction copings have silver in the PFM metal, I'm not sure I want to deal with the silver but in reading past posts it's not a issue with many labs.
I been using laser copings from dale and bego,, both are excelent , you can have noble and high noble laser sinter coping also from dale.,
now , on the non precious metal copings, to answer your bonding question. I experimented before starting to use these copings and found that
the best way to handle them is the following
since degassing is not necesary with these copings, and since we are already used to the degassing step, what I ended up doing and still do
is insted of the degass step, I do a extra opaque fireing, the way i do the first is extreammly thing just bearly a wash almost nothing.,
2nd ussual first opaque and ,and 3rd ussual 2 nd opaque.
after doing this I tried to break off the porcelain of some crowns to see how the opaque holds up and sure enough it remains bonded lot 70% nicer
than regular 2 opaque technique.
.
for me its hard to return to wax and cast, laser sintering is the way to go, I tried printed and cast also, but you have to adjust to fit, not like laser , laser fits like if they where painted on.
