Matrix Band - Precontour Interproximal Region - Complex Direct Restorations

This little tip may play a huge role when placing large, complex restorations (amalgam and composite). Preburnish the interproximal regions of your metal matrix band to obtain a better contact and gingival health - and decrease the likely hood of food impaction from the buccal and lingual. Of course, if contours and contacts are a huge issue - a full coverage restoration (indirect), will hopefully solve those problems.
This was a great tip that I read about in Sturdevant's and Summit's textbooks - later shown to me by Dr. Queso. (Thanks Ryan).

This tooth is a part of a demonstration of complex amalgam restorations. The pins are controversial, however, a discussion regarding complex amalgam restorations is not complete without bonding, slots, grooves and pins. More to follow!

After 2 years, finally this guy clear all my confusion of toffimire bands.

thank you Mr all things dentistry for making my every day dental practice better

I"m thinking that perhaps wedging will seal off the gingival portion (sorry I didn't place that into this video), and if that doesn't help - there are a few instruments (interproximal carver) that can help during carving. I'll have more of that in a few days. I just posted is an interesting tip regarding customizing wedges from a fellow resident. I can't post links in the reply!
Thanks for the comment. Ashley

This is awesome, most of the offices I work in don't even have sectional matrix available, and it's been a struggle to get a good contact!

Thank you very much for the demonstration, It's the small things that really matter.

Thank you doc...your suggestions are so valuable!!

[@fishribbon]

Thanks, Doc, for distilled info

Thank you. This issue of the wedge interfering with the natural desired contour usually occur if the wedge hight is protruding coronally too much above the gingival margin, or if the clinical crown is too much short. Ideally the wedge should be not protuding too much coronally after being wedged tightly so you will have enough clearance in interdental triangle area to perform the matrix burnishing and contouring. So how to get to this ideal wedge is by 2 main strategies: 1) By "removing" the excess wedge which is coronal to the gingival margin by large round carbide or by large spoon excavator (excavate in one direction to avoid dislodging the wedge). Then you just move the wedge out a little just to allow your matrix to slide in then tighten the wedge again.
2) sometimes you have to remove (excise) a lttle of interdental papilla to to allow the wedge contact to tooth to be more apical to your gingival margin.

All your solutions will cause lots of bleeding though.

Or something called anotomical wedge

Cool vid, I wonder if you could use SSC contouring pliers to tuck in the gingival and bulge out the contact more naturally too.

Sir, how to prevent gingival laceration during matrix placement.

Thank you

[@drhakimvaaand2936]

hi dr
nice explanation
what's the reason of burnishing matrix?

[@vilelaclaurevilelaclaure4547]

thanks for recomend

[@staver76]

What do you think of this vs a dixieland precontoured band?

[@skdavidnba]

thank you!!

[@jonathanwirth3420]

Are those guitar strings sticking out of that tooth you're restoring?

[@mukeshadwani4695]

Thankyu sir🙏

[@yuianleo]

thx a lot, this is useful!

[@erodoeht]

Hi Mark thanks for the tips. Just wondering though, after burnishing as such, how do you deal with the possible issue of knife edge overhangs that may result because of the curved matrix?

[@lauralove3162]

Manicure 💅

[@dr.danielespinel1690]

easier make it outside the patience mouth that give de contact forme with the matrix inside the mouth. thanks a lot. :-)

You don't need pins with composite if you are bonding to dentin and enamel. Waste of time and completely unnecessary in my opinion!!

In the video he said its for an unrelated amalgam video.
