I went to your course a few years ago. I could not get this technique to work in practice because when the caries is apical to the PDL of the rest of the tooth the bottom of the band either cuts into the gums causing bleeding or the surrounding gum does not let the band seat apically enough to reach the bottom of the prep. This technique only seems to work on a typodont with no PDL. Why can't a band be made with the bottom of the band extending apically to the rest of the band like the old molar bands?
@GarrisonDental4 жыл бұрын
I am sorry you are having difficulty. This is an extremely difficult procedure the deeper you go subgingival, but I assure you the band works on more than the typodont. I use it exclusively and like anything else, practice and experience make the difference. Sometimes I do place another sectional matrix band between the reel-matrix DME band and the tooth so that the reel-matrix DME band acts essentially as a retainer to hold the other sectional matrix band tightly against the tooth. We have tested the design you mention and it was less effective than placing another sectional matrix band in place for a few reasons. - Dr. Matt Nejad
@gregwarrior3 жыл бұрын
practitioner here, i also have this problem , it’s due to big mesial and distal height difference,this causes instability when tightening the band. I solve this by detaching the bad from the reel and customizing it a bit. But the biggest trick that makes a difference is to simply do gingivectomy. it’s just impossible to get a reliable seal when soft tissue is present. I’ve tried multiple products from multiple companies , Torr VM , garrison, polydentia, dentsply, bioclear. Non will give you a reliable seal unless you do soft tissue management!
@ronyeahright9536 Жыл бұрын
usually when seating any matrix band, if you have one side that has very deep decay and can't get that side of the band fully down there, take the band out, and use some crown and bridge scissors to cut out a "U" shape on the OPPOSITE side of the problematic deeper side; this will allow the band to go deeper and hopefully reach the bottom of the prep.

Also, how do you account for bonding to cementum? Would you use GI cement for marginal elevation, or do you stick to composite resin?
@taylorshank94432 жыл бұрын
Using a 4th generation bonding system (kerr optibond fl) can achieve a bond strength of around 40mpa, similar to that found at the natural DEJ. I use composite, not GI or RMGI. “Open sandwich” techniques are not recommended anymore as the GI has poor resistance to wear and degradation over time

Why Dr Matt Nejad use plastic model wiout applying rubberdam isolation for demonstration?
@GarrisonDental Жыл бұрын
Thanks for the question. For demonstration purposes, rubber dams are not placed on the typodonts (unless it's a video on how to place rubber dam). Also, depending on how deep the margin goes subgingivally, you may not be able to place a rubber dam until you've built up your margin to be supragingival.

@jameshastings72523 жыл бұрын
This procedure is used to raise the root surface/restorative margin to the level of the gingiva or slightly above. Although it's possible to "just...take an impression" your restoration margin will be subgingival and is likely to create chronic inflammation, bone loss and eventual failure of your restoration. This is an alternative to invasive crown lengthening and subsequent creation of a food trap and inability to cleanse the area properly. Once you have mastered the Deep Margin Elevation procedure it's not time comsuming and it creates value. And you must charge for it.
@sorinher13 жыл бұрын
This technique seems to be very unpredictable and unsafe.Bonding strength of the composite to dentin is very weak and because of the future leakeage after the composite contraction you can expect secondary carries.The elevated margin can also fracture as a result of pression from the crown or onlay margin.I prefer to crown al the cavities margins and even CLP.Maybe reinforced glass ionomer cement would be a better choice for this sensitive technique.
@BiomimeticDentistry3 жыл бұрын
@@sorinher1 Hi Sorin. Thank you. Interestingly, the scientific publications are in complete contrast to what you are saying. Of course adequate isolation is essential but doing good dentistry is a prerequisite to anything lasting. If you are being honest, every dental procedure is technique sensitive, from a simple amalgam to a gold crown. I think its time to stop using the excuse of technique sensitivity and focus on doing good work. Using glass ionomer would be a terrible idea for this but it is a difficult procedure that many have mastered and it has been published and used for over 10 years now.
@BiomimeticDentistry3 жыл бұрын
Also, it is much more manageable to maintain optimal isolation with the band in place and rubber dam while you elevate the margin, than it is to cement and remove excess cement and polymerize without contamination. The matrix forms a seal and a wall, but even the best rubber dam would be very difficult to maintain an optimal enviornment during cementation when you are 2-3 mm subgingival.

Wow! a quick question, can we do this then continue with regular composite filling right? just change the matrix band and use tofflemire or sectional right? thank you!

Yes! That's exactly right. You use the margin elevation band to build up the margin on teeth where the margin is subgingival. Then, you are able to switch to your regular matrix or tofflemire system to complete the restoration.

Great presentation! Thank for sharing. Is the Reel Matrix tensioning instrument easy to tight and untight the reel matrix? It looks bulky to be used to tight the reel matrix in areas of Upper first or second molars? Thanks
@GarrisonDental7 ай бұрын
It is fairly simple to tighten the bands down and not too difficult to loosen it. Normally you would loosen it up enough after restoring until you can get leverage to pull the band off the tooth, so you aren't tightening and loosening the band repeatedly. As far as being bulky, once the band is placed, you no longer have the tensioning instrument in your way, unlike a tofflemire retainer. The "neck" of the instrument is long enough to reach in areas that may be difficult otherwise.
@jstimmel13 жыл бұрын
I really liked the video and your approach to these types of cases! I understand why you like to use heated, packable composite, but are you ever concerned about being able to cure adequately? In the typodont case the lingual cusps are missing so I don't think getting the curing light close to the composite would be too hard, but what if the lingual cusps were intact and you couldn't place the curing light very close to the composite? Would you consider some type of auto-polymerizing material?
@BiomimeticDentistry3 жыл бұрын
Thank you! No, it's really not a concern to cure in a deep box. Simply cure from the buccal and lingual sides. If necessary, you can use an extension on your curing light (Ultradent makes one for the Valo which I recommend) but I hardly use that. I prefer to use light-cured only so I have full control of the contour and also you need to be quick to avoid moisture, heme, or any other contamination so light-cure is ideal for this. When you cure from the buccal and lingual, its unlikely that any portion of the composite is more than 4 mm away from the light and that will do the trick. All the Best, MN

What are your techniques to get inverted rubber dam on the deep margins to complete the DME process? Maybe your next video ;)
@GarrisonDental4 жыл бұрын
That sounds like a great idea for another video. When doing the DME process my goal is to keep the rubber dam displaced laterally away from the tooth while I place the matrix band in. I have my assistant help me move the dam out of the way by stretching it while the band is placed, then once the DME band is in position, the dam applies pressure against the band and helps maintain the isolation. I am not super concerned with inverting the dam. If the DME band is placed directly above an inverted dam, then it will usually interfere with the band functioning as intended and the dam will often will push the band out of the sulcus. - Dr. Matt Nejad
