Greater Curve Standard Brass Band- MODL composite #2

Posted on October 23 2018

Introduction:

The malleability of the Greater Curve brass makes it easier to burnish desirable contours and make contact openings.

 

Before #2

Step 1

 

Prep

Step 2

Considered recommending a crown, but there was sound dentin supporting the remaining cusps.

Step 3

The brass is very malleable. Note how the brass remains crimped over the adjacent tooth's marginal ridge which made it easy to visualize placement of the contact opening. I tried to position the mirror in order to show the contact opening but I could not get the mirror angled properly.

Composite

Step 4

I used Activa A2 as a base and placed Filtek on the occlusal surface.

Step 5

Conclusion:

Activa (Pulpdent)

Advantages:

1) Easy and fast to place because it is a flowable.

2) So far it appears to wear as well as any other composite.

3) Margins are stain resistant and blend well

Disadvantages:

1) Easy to capture bubbles on the margins and within the composite.

2) More fracture prone than conventional composite. Pulpdent says otherwise, but that has not been my observation.

 

Based on my observations from above, this is how I use Activa clinically:

• Class V's. It blends beautifully against the tooth. Margins are stain resistant.

• Buildup under crowns. I like the bioactivity.

• Conservative Class II’s, Class III’s.

• As a base under large Class II’s and Class IV’s. I place Filtek over the Activa for color control and fracture resistance.

    Very nice. Now dump the Activa and switch to Beautifil Flow by Shofu. Shade A-2 blends with almost anything……hard as rock…….ZERO bubble internally.

    The U band is good for Class V’s because it is very open and provides access. I use the stainless U band for Class V’s because it is easier to get the base of the band past the prep at the gingival margin.
    Also, the U band is good for wide embrasure contacts on molars.

    I use both the brass and the stainless. Depends on the situation. When it is easy to slip the band around the tooth and below margins, the brass is the way to go due to malleability.

    The stainless band is better choice for:
    1) Tight intact contacts. The brass scrunches more readily and will not slide through a tight contact.
    2) Deep preps. The brass can crimp when it gets hung up on a deep margin. (Stainless a good choice for Class V’s.)
    3) Aggressive tightening for a gingival seal. Can not turn the screw as tight for the brass. It will break.

    Are you using brass bands majority of time?

    So I should use the brass bands now instead of the steel wide bands? I need to get used to the U bands still.
