Creating amazing provisionals primes the patient for a positive treatment experience and ensures they’ll be content even before the final veneers. Read on for the last post in our four-part shrink wrap provisionals fabrication series:

Checking Occlusion and Polishing Shrink Wrap Provisionals

After cleaning off most of the excess from the provisional with a universal scaler, extra fine mosquito diamond, and a brownie, use the same diamond to open the linguo-gingival embrasures with the intent that the patient should be able to pass floss through them. This also keeps the tissue as healthy as possible for the seat later on.

Now that you’ve done all your flash trim, you should check the protrusive and right and left excursive occlusion, making sure you have even marks and no fremitus. Check intercuspal position to ensure you have no fremitus there as well, either lying back or with the patient in the alert feeding position.

With everything trimmed and ready to go, the last step is simply to polish. You can use the Brasseler Featherlite porcelain polishing system running in a latch handpiece. Utilize the first of three polishers at about 15,000 RMP, then move to the second polisher at about 10,000 RPM. They can be run at a higher speed, but you’ll get way fewer uses out of the polishers. Finally, run the last of the three polishers at about 7,000 RPM.

If you notice a porosity after cleaning out the residue from the polishing, you can use a Venus Diamond flowable that matches the esthetics of the bisacryl exactly. Fill the void by manipulating the side of the explorer to drag away excess and feather it out. Then simply light cure so that food doesn’t pack into the void.

The final step of this shrink wrap technique is to use Dialite polishing paste from Brasseler in an impregnated bristle brush to create a perfectly smooth finish. The entire process of provisionalization should take no more than about fifteen minutes.

The Shrink Wrap Technique is taught in our hands on course Excellence in Bonded Porcelain.
