Omnichroma Results Continue to Impress


In Chicago this past spring (2019) Tokuyama introduced OmniChroma composite.  This has been a game changing restorative material for a lot of doctors.

I was fortunate enough to be able to beta test the material and I am now approaching about 13-14 months of clinical cases.  What I am seeing clinically is cases that are holding up well.  Margins are intact, material wear is minimal, they are still highly polished, and the shade match is still “spot on”.

For those of you who don’t know the details of Omnichroma, it is a composite resin that is designed to be a single shade to match all clinical situations.  The company accomplishes this through a pretty unique filler particle system.  Composites are normally resin with a mix of filler particles for strength and polishability.  Most composites use a variety of sizes of these particles, larger ones for strength and smaller ones for polish and under high magnification, these particles look like tiny pieces of gravel.

Because of the non-uniform shapes of these particles, light is bounced around at a myriad of different angles. 

What Tokuyama managed to do was to figure out a way to make filler particles that are round spheres.  These spheres cause the light the reflect and refract in uniform ways that allow the composite to pick up the shade of the surrounding tooth structure.  This means that Omnichroma comes in a single shade and, when the material is polymerized, that single shade picks up the nuances of the surrounding tooth structure to create a near perfect match.

When Tokuyama approached me about the product, I must admit I was a bit skeptical.  However some experimental time testing it on extracted teeth showed me that my concerns were unfounded.  Now 13-14 months into my usage of the material, I continue to be impressed with it.

If you are looking for way to simplify your restorative procedures, I definitely feel you should give Omnichroma a try.
