      A question again if you can help im using semi only because i cast nobel implants castable that has precious base. People told me that they use a non precious metal to cast and they dont have problems of merging the two metals. Do anybody know anything. I dont want to use semi precious any more and my doc likes nobel

      Didn't like the answer you got yesterday? If people have told you that you can do it, why aren't you?

      Why not use a non precious ucla base if you must cast in non precious. Here in the UK there are several 3rd party manufacturers selling them, eg Talladium and Omnident.

      You can Google it and find 100 places that say not to do it but if we can find just one person to say it's okay on an Internet forum we'll be good to go.......

      True, which is why I haven't yet dipped my toe in using these abutments, but here in europe they seem to be getting more popular. For instance Straumann bought into Medentika principally for the reason that 3rd party companies are proving to be very popular on a component cost basis. eg below

      http://us10.campaign-archive2.com/?u=8416b9250c26e99453134362f&id=b1e57d4de9&e=aa26fa5cdf

      So I would imagine that there are a lot of labs and techs/surgeons using these components regularly. I heard a rumour that Straumann may soften their stance on crco abutments in the near future and mill them from custom cad designs Hmmmm2.

      don't use non precious. as a general rule for almost anything, including UCLAs, that's what you should think.
      just don't use non precious.

      CrCo may not react with Ti, but the NB UCLA bases are in fact Au, it says on the package. CrCo and gold could have a reaction. But really why spend $300 on an abutment just to cast a nickels worth of metal over it..?

      ..because the lab fees are too high and this is forcing some drs to become techs through no fault of their own?

      If you are looking for cheap then buy a plastic UCLA pattern and cast the interface.

      All quality UCLA abutments use a non oxidizing gold which allows for the bond of precious metal. It has been proven that an alloy like 65sf is the best material for this abutment. PD based alloys are the worst and ironically are the #1 alloy used today.

      You will destroy the gold if you chuck NP at it.
