Adding to PFM that has been in mouth

[gacris]

Hey guys. One of my accounts wants me to add to a PFM bridge that he seated temporarily. It’s been in the patient’s mouth for about a month. It’s been so long since I’ve had to do this that I don’t recall what I used to do prior to adding. I remember letting it sit in the furnace at idle temp for a while first? Ultrasonic with alcohol? Can someone refresh my memory?

That's about all you can do. 1 Month you'll probably be ok. But definitely still a risk there. If you can do the job only using the lower fusing add-on for your porcelain you'll reduce the risk of damaging the existing restoration.

Always a risk of bubbling/blowing up of porcelain but leave in oven at idle temp for a weekend, at least one full day....then cross your fingers, do your lucky dance and pray the PFM Gods love you that day!!! All you can do.

What are you adding? A contact?
I would put up a fuss if the adjacent tooth was a 40 year old amalgam.

One month should not be a problem. I'd probably put it in the ultrasound with peroxide, to kill of the bacterias...

Soak overnight in this and then add.

Thanks for all the tips. I'm just going to cross my fingers and toes and hope for the best!

If I did the bridge I’ll add to it no problems because I record my ceramics recipes, but I’ll be hesitant to to add to someone’s else made fixed restorations, soak in the furnace and ultrasonic cleaning will do the trick

A month no problem.. Its when you get those ones that have been in the mouth for years that become headaches and the outcome is what the doc gets. No warranty implied or expressed. I still use LFC from years ago.
