I just broke ten Surpass one year storage samples. Now keep in mind:

- that the technique was not quite as refined as it is now.
- that I did not use new teeth (new teeth yield higher bond strengths)
- that my machine routinely generates numbers slightly lower than those at CRA or Tufts




I got 55.6 MPa at one year.

A great day in NYC with Gordon Christensen!

He put up this super picture of Surpass while he told the group how wonderful this new adhesive is. Stuffed a mike in my face and asked me to describe the protocol for Surpass. "Rub on part 1 for 10 seconds, 3 quick brushfuls of part 2 and dry the daylights out of it, paint on part 3 and thin as much as you want and light cure." "And the bond strength" asked GC. "You yourself got 51 MPa immediate". To which he said "I sure did!" And I continued "And the bond strength does not diminish over time actually increases over a year!" GC = "Did anyone notice. No rinsing of the etch. No sensitivity!" While this was going on he put up the picture of the 3 of us at CR last July. Did basically the same with Interface. Spent more time on these than any other adhesive and mentioned no other porcelain system. Several asked me about Surpass at the break. It was magnificent!!

He did mentioned that "John is my good friend, even if he is a bit grouchy".
