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

Step 1

Uneven marginal ridges

Funky anatomy

Rotated Teeth

Occlusal stamp for #20 made prior to prep

Step 2

Triad Gel is worked around the occlusal surface with the wooden cotton applicator and then cured to the stick

Occlusal stamp for #21

Step 3

You need to capture just the periphery of the occlusal surface. Further extension will get in the way.

Verifying fit of stamp on #21

Step 4

 

#20 MOD prep. #21 DO prep.

Step 5

Wedges were placed to protect the rubber dam during prepping.

Greater Curve setup on #20

Step 6

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

Step 7

Stamp may need peripheral adjustments to make certain it will fit within the matrix.

SonicFill placed and occlusal stamp is seated and pressure applied

Step 9

Notice the flash extending up the mesial of#19. You can see how the stamp is placing a rounded marginal ridge in the originalposition.

Step 10

Initial shaping of margins. Bulk filled SonicFill is light cured.

#20 Completed

Step 11

 

Greater Curve setup for #21.

Step 12

 

#21 after stamping and initial cleanup

Step 13

 

Ready for dam removal

Step 14

 

Final MOD #20 and DO #21

Step 15

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.

    Marvin – The teflon tape prevents the composite from sticking to the stamp when compressing the composite into the tooth.

    Omar – There is no back pull on the uncured composite when using teflon tape around the stamp. The stamp releases cleanly.

    Karwan – I stretch the Teflon around the stamp and twist the ends to keep the Teflon secure around the stamp (I do not place the Teflon on the tooth). Purposely overfill the tooth by a slight amount so the composite will be forced against and into the tooth. You can use layering composite but a single shot (bulk) composite works best. I do not have any additional photos at this time, my plan is to make a video of this procedure in the future.

    Doc. Thanks for your nice case,in step 7 when you placed Teflon did you fold the stamp or placed Teflon on tooth and then applied pressurewhy? can you please send me my email more illustrated pictures about this point

    how much did you fill the tooth before applying the stamp? did you you overfill the tooth for this purpose? I mean did you use layering composite or not just singleshot composite and apply stamp?
    Your colleague Karwan,

    warm regards,

    Is there no worry that the negative pressure of taking off the stamp before curing and even in presence of teflon, create a void some where .

    interesting time saver. why are you using Teflon tape? why not just place stamp on tooth and compress down with an instrument like a ball burnisher?
