I'm doing my first "screwmentation" with zirconia coming up what is the best way to bond the resin to close the access hole. The same would apply to
Closing Endo access. I use surpass as my bonding agent and have an air abrasion unit.

Thanks all

Jake

Nothing bonds to zirconia so it really doesn't matter. Be sure to sandblast the internal of the crown prior to cementing it to the abutment (keep the abutment screw access filled with teflon tape). The next step is to torque down the abutment/crown complex. Then Surpass 1-2-3-composite or you can do Interface (dwell 10 secs then dry) and Surpass 2-3-composite. Best of luck - Tom

Thanks Tom

I thought interface doesn't do anything to zirconia.

It will help you adapt resin to the zirconia. Do sandblast the zirconia first.
