Just busted off a set of one month samples of Surpass.

The average (which I have not finally calculated) is well over 60 mPa, with one sample reaching 70.9 mPa, a new high single test sample number for me.

This stuff is amazing. Very Happy

Don't worry master. I was just wondering. I follow your steps to the anal degree. My thinking is someone will miss this step and want to know if he has clinical bond strength. Also always looking to save a second or two. time is money you know.

have a blessed holiday. all the best,
stu

Success is the best way to save money.

Happy Holidays, Satch!

Currently in the midst of a series of long term SBS tests concerning mechanically assisted bonding. Preliminary results on flat dentin show Surpass head and shoulders above anything else out there! Second place goes to Simplicity. Prelude had about 1/2 the SBS numbers of Surpass. Adper Prompt finished a very dismal dead last! The others were somewhere in the middle but nothing is even close to Surpass!!

This is such a great product.

I know some might think that's just hyperbole, but it's not. The material is just ever so good.

In the most recent experiment concerning mechanically assisted adhesion, Simplicity SBS to dentin average was in the mid to upper 40's while Surpass was mid to upper 50's. Nothing else tested was higher than mid to upper 30's.

Sorry for the delay but I was away fishing in Fla. NOT catching - just fishing! Have a lot of very clean washed lures.

Just going over the condition of restorations (in-vivo) which were placed a bit over a year and a half ago using Surpass. Many of these are really heroic efforts replacing large amounts of tooth structure. Documented the first 100 restoratons looking at retention and margin quality. Not one restoration has failed and the margins appear spectacular!

Super Stuff!!!

The bond strength to dentin seems spectacular. How does the bond strength to enamel compare with a phosphoric acid etched system - for example Optibond Solo?

When I was at Tufts, we ran Surpass against Excite and H3PO4 etched enamel. We got 46 MPa for Excite, and 49 MPa for Surpass. I'd expect Solo to exhibit similar numbers.

Acid etched enamel tops out around 45-50 MPa in our test methodology no matter whose bonding system it is, provided it really etches well.

The bottom line is that it will bond to enamel as well as anything there is. If you check the website you'll see the enamel numbers for Surpass against 4th generation systems.

We did Surpass on enamel just yesterday - 2 hours 48.4 MPa

As Surpass is a universal adhesive I dumped all the wash-etch stuff years ago. Except for experimental purposes. When one does the job better in all situations why bother having several for patient use?!
