Dr Lincoln Harris shares his protocol for polishing composite resin fillings. He offers tips for polishing anatomy without removing it and the products used to achieve these effects.

Cup One

From a white one gloss cup to purple and then to orange. To create texture on the surface of the tooth watch how Dr Harris skips the first polishing cup and moves straight to the second cup in the series.

Cup Two

One can not be aggressive enough to actually smooth the big scratches of the big anatomy. It will start polishing and it will round things over but if there is a bit of a scratch in the tooth it's not going to be removed.

Surface texture

It is basically is a bunch of scratches so if the goal on the surface of the finished resin is to have some sort of texture, some scratches will need to remain.

Polishing then is just a process of making scratches smaller. 

Start with big scratches, smooth them down to small scratches, then make them very small scratches.

Finishing

It can take a dreadfully long time. Sometimes finishing can take nearly as long as it took to put the filling in place, however finishing really does make a big difference.

This is why sometimes dentists bring patients back for a second visit to do the finishing when they're fresh.

 Dr Harris Shares Which Polishing Cups He Uses

Watch how he uses a diamond bur while spinning the cup to sharpen the polishing edge making it more flexible so that it can be bent subgingival.

Do you want a smooth and glossy finish, or a glossy texture? Dr Harris demonstrates which cups to use in order to create different results.
