[Prosthetics]  impression for Zr custom abutment

what is the best way to make a final impression of a Zr CAD/CAM custom abutment and is it true that if you take the custom abutment out it will be useless becuase you won't have the correct orientation!!!

Hi, Katie. That is a good question. To be honest with you i dont have any experiece with syringe mixing of impergum. My only experience is with using pentamix machine. I believe that they are both same materials and work just as well. If you are happy with the way you have been using impergum, I am sure it will work just as well for implant impressions as well. - mark kwon

Hi Mark! I know you recommend using Impergum for impressions for implants. I do use Impergum now, but the traditional way of mixing it. What are your thoughts on the syringe mixing Impregum (like the PVS we use)? Is it just as accurate?

I don't quite understand the question but I will do my best to answer them. In my opinion, the best impression material is Impergum, hands down. It's poly-ether.. Hydrophilic and sets hard. Especially useful when using closed tray technique. As far as the answer to your second question is No. You should be able to re-orient the abutment provided that it is engaging type the connection. Hope that helps. - mark
