Onlay Tooth Preparation of Amalgam Filled Tooth

75 Rating(s).


Posted on By Jens Knab In Other

Is there any rule on preparing amalgam filled tooth
especially leaving amalgam blues.Is there any effect in cementing onlay ceramic fillings if we leave amalgam blues?
We had a parafunctional patient, onlay failed/decemented after 1 month, we used variolink as instructed.Could you take a look at our scanfile, and leave your suggestion for the cause of failure?
We used emax cad blocks.

Hi Jens;
You cannot bond to amalgam.
The benefit of Emax is that it is bondable.
May I ask if you used a rubber dam to place your restoration?
Thanks,
gerald

Of course amalgam was already fully removed,
we didn use rubber dam, but cords, to prevent saliva contamination. what I mean is that dentin was still dicsolored, I guess a bonding issue due to collapsed dentine?
Thanks for you help, hope to get more feedbacks.
