Can you comment on the use of the interproximator and finishing tips that are quick and effective?

Hi David,

As you know, I am writing an article that features some of the concepts the Opinion Leaders conveyed upon.

I have attached an anterior case. It does not use an interproximator, and I am still not rockin’ w/the rock star finish, but I think it is good.

I tried to outline the infinity margin – can you elaborate on it so we are on the same page.

Can you comment on the use of the interproximator and finishing tips that are quick and effective? I still can’t seem to use the rubber points to my advantage.

Best,

Jeffrey

DR. CLARK'S RESPONSE:

The outline is nicely displayed and looks just right. Remember that caries resistance is augmented by the distance that we create between the cavosurface and the dentin or the DEJ. You also have ten times the enamel rods and they are all cut at an oblique angle, so this should be a bulletproof restoration.

Polishing sequence

  1. Carbide or diamond to remove gross excess. (if I get it just right I try to skip this step) Try not to touch any enamel.

  2. Brownie at right angles, wet and at medium speed, preferably in an electric handpiece

  3. Medium grit 3M disc,typically inverted

  4. Coarse pumice, the world's best pre-polisher. Evaluate the matt finish of the composite at high magnification which contrasts nicely from the shiny enamel. Back up and touch up as needed use the special Hartzell handle with a 12 blade as needed in both traditional and back action to clear the margins of flash.

  5. Finish with the SS White polisher. Deeper interprox areas can be reached with fine and extra fine 3M discs, usually inverted on the manual.


The DVD or the web shows the polish if you want to take another peek

Be patient, polishing and sculpting are a very finesse art form that very few clinicians ever master when it comes to resins or porcelain. It remains a challenge to all of us.

Cheers,

David
