I use Surpass for everything.

I like Bioclear matrixes for anterior fills, but Dr.Clark's technique calls for using a single step bonding agent. His rationalle is that by placing the BA then the flowable then the paste, the injection moulding fills in all the voids. But if I use surpass, I want to cure the BA with a little flowable first. that defeats the point of injection moulding.

How do I reconcile the Surpass protocol with the Bioclear matrix technique?

Is it ok to co-cure? I would think that not enough light energy gets to the BA layer!

What if I use Injectafil as the paste composite? Again, I am concerned that the light energy getting through the Injectafil will be inadequate to cure the BA.

What are your thoughts?

Thanks in advance,

Rix

I've been using both Simplicity for 8 years and Surpass for over 4 years. Dr. Kanca has said you can co-polymerize your Simplicity 2 or Surpass 3 (after thoroughly drying both) with your flowable of choice. I would not do this alongside your packable composite. It may work, but it only takes 10 seconds more to do it right. I don't know Dr. Clark's technique, so take it for what it's worth.

I personally place the 3 surpasses, then the bioclear matrix, then a touch of flowable and cure-- then I will bulk cure the rest of the packable when using the bioclear matrices--
This method makes certain that your hybridized layer is solid-- if you try to place the matrix after the initial cure, you can blocked out by the surpass sneaking into/below the contact.

The bioclear technique is nice when teeth are fairly monochromatic- but most of the time, I like to layer a couple of different shades/translucent composites to get the desired esthetic effect.

hope that helps--

Brad,
yeah, that sounds good. I'll try that next time.

But I still think that it will defeat the purpose of injection moulding to eliminate voids at the margins.
But definitely worth trying.

I agree that it is only really good for the monochromatic teeth situations.

Thanks,
