Anyone casting to TI interface?

[charles hallam cdt]

Have cast gold adpt ucla interfaces but not tried ti

Wouldn't you have to cast it under vacuum?

Hey we already had a v word thread. Don't start that again.

Sorry, I'll fix it.
Wouldn't you have to cast it without any air present?

 

[charles hallam cdt]

What would ya say if I told ya I tried it with success. No lack of air

What did you cast to it?

 

[charles hallam cdt]

High pd alloy noble. Drilled mechanical retention holes in the screw channel. Of course only trying it for screw retained crown. Dr. Wants pfm.

Expect a remake...Ti is covered with oxides at casting temp, so there's no metal to metal bond present. Eventually will become loose due to galvanic reaction...seen one of those not to long ago...dentist wasn't thrilled with her lab...just sayin'

I'd say you are working without a net.
I don't think the traditional gold UCLA abutment exists just so companies can sell more gold.
Why do you wish to go this route rather than just casting to a UCLA?

just cast the mesio structure separately and then cement it to the ti base.

 

[charles hallam cdt]

Even with mechanical retention cut in. Yes I noticed the extreme oxide after casting and porc bake. Dr is aware of what I'm doing was very up front with him.

That will b my next step if this fails. Hear 3m makes a good cement

Nice. How about the patient?

I know the patient also. They kow they're the proverbial guinea pig. If fails I will replace. No charge of course

 

[charles hallam cdt]

The whole reason trying this is I'm tired of paying $250 for ucla abuts from noble.

 

[2thm8kr]

Other companies make aftermarket UCLA type abutments for most Nobel platforms.

....and people are worried about sending stuff to China because they don't know what they are getting....

This is why the FDA or some other Federal agency will eventually be more involved in dental labs.

If cut a horizontal and vertical retention groves, it's not going to fail. No matter what oxide forms.
My two cents! Mill customs is my choice

I'm not trying to hide or b deceive. If I thought what I was trying was going to cause lawsuit I wouldn't do it. Have you never experimented in the lab
