Can anyone tell me what opaque they use for titanium implant bars. We have had some issues with it delaminating.
Thanks
Thanks
We use GC products, We use GC metal primer after we sandblast, and steam clean the bar. We then apply THIN layers of Gradia G11 opaque and on the final cure we sprinkle what ever polymer I will be using to process with. This allow true chemical bonding of the opaque to the bar and the acrylic to the opaque. Just one time having to strip a bar will tell you that it indeed is the best results obtainable.
GC is good!
But I still prefer to use Rocatec to create a mechanical/chemical bond between Ti and the opaque layer.
Anodize it! That won't delaminate.
Between metal primer and the fact that it is an oxide layer with sharp finish lines on the Ti framework, would that not facilitate for a good bond between the Ti and the acrylic? I am asking out of curiosity. Just a theory of mine. Although I am not a chemist, but do use a lot of common sense. I may be 180 degrees the wrong way in my thinking, maybe not. I've got a few patients with this currently. They will be in for hygiene and I will be following these cases very closely. Any input is appreciated, this is why I asked about a hybrid thread. Works here just fine I guess.
I would second John on his answer......
My reason is to prefer to opaque, because, my frame design is actually support the teeth itself, and that is require dentin colored opaque.....
I am using the Rocatec system for years now......finishing about an average of 2 cases per week without having zero de-bonding issues!
