If you have a problem bonding attachments to porcelain crowns or bridges, there are at least two products that may help you have better success.
One is Ormco's Porcelain Primer. Etch the tooth normally, apply the primer without washing off the phosphoric acid, and proceed normally.
Another product is Den-Mat's Porcelain Repair Kit, available through your local dental supplier. The kit is normally used to repair fractured porcelain, and it bonds quite well. The kit is expensive, but worth it if your bonds hold. Undoubtedly, there are other products on the market which will do a job similar to these two products.
Removing the bonded attachment from porcelain has not been a problem. Getting the bonds to stay has been the problem.
