Using Occlusal Stamping with the Greater Curve
Posted on January 27 2017
Thank you Dr. Cory Glenn. This makes composites even more fun
#20 and 21
Uneven marginal ridges
Occlusal stamp for #20 made prior to prep
Triad Gel is worked around the occlusal surface with the wooden cotton applicator and then cured to the stick
Occlusal stamp for #21
You need to capture just the periphery of the occlusal surface. Further extension will get in the way.
Verifying fit of stamp on #21
#20 MOD prep. #21 DO prep.
Wedges were placed to protect the rubber dam during prepping.
Greater Curve setup on #20
Distal contact opening is evident. Contact will have width and depth and intimately touch the entire contact surface on the mesial of #19.
I placed Teflon tape over the occlusal stamp
Stamp may need peripheral adjustments to make certain it will fit within the matrix.
SonicFill placed and occlusal stamp is seated and pressure applied
Appearance after the stamp is removed
Notice the flash extending up the mesial of#19. You can see how the stamp is placing a rounded marginal ridge in the originalposition.

Final MOD #20 and DO #21
Patient enjoyed viewing the final photo. I closely duplicated the original anatomy with minimal adjustment needed after the rubber dam was removed. Reestablished the uneven marginal ridges. Achieved tight contacts with width and depth on rotated teeth. I’m happy with that.
just examined one of my original Sonicfills. It was a 2 years old large MO composite on #31. Margins were excellent except for a small hard pit void on an occlusal margin. I don’t blame that on the SonicFill material, I can be guilty of such a thing with any composite material. This is conjecture, but I believe the downward forceful pressure of the stamp technique will reduce the occurrence of marginal defects.
