How To Get Good Contact On A Class II Composite Restoration

[@jerryhill4893]

Something to consider. I don't ever use flowable in the box, due to the polymerization shrinkage that occurs. Since flowable is unfilled with particles, it has the highest shrinkage of all. Thus, more opportunity for leakage and recurring decay. Good luck.

bad camera position, really want to see the beginning of making the hole in detail

Look at the tooth in the beginning and look at it at the end. Your lingual embrasure needs work... way too bulky and contact is too wide. You should have held the band against the lingual end of the tooth with a flat composite instrument while curing it so that you could keep the buccal contact correct but keep the lingual embrasure from looking too bulky. If you took an x-ray and looked at the radiograph, I'm also guessing that the marginal ridge contour in your composite is straighter (less round) than the natural tooth was, so floss won't be guided through the teeth naturally.. this is caused from not shaping the composite before curing along the marginal ridge area. You will spend more time shaping composite after it's cured than if you do it in the soft stage. The last thing I would have done differently is shape the occlusal anatomy to almost perfect before curing. Once you cure and then touch a drill to the composite, you introduce microfractures in the composite and potentially lower the lifespan of it. It's always worse to contour composite with burs after curing in terms of longevity. Keep in mind you'll probably have to adjust further once you check the bite, which is even more drilling on the composite.

relax buddy.

Kevin Pham naa he’s right. Dentists should only be posting videos if the end result is ideal. Not shoddy like this.

Such a good comment!

Tanks for sharing. Good techniques

I'm a 2nd year dental student at ACTA (Netherlands), and I know there are multiple ways of working, but I noticed some things of which I am instructed not to do, so I am wondering what are your thoughts about these observations; No suction when rinsing etch - etch may affect other teeth Fluid between tooth and matrix when bonding - no water allowed Blowing on bonding before hardening - creating air bubbles, no even spread and spreading bond all over the place Using flowable - no proof of better adaptation + not strong

[@matthewscott9311]

you are supposed to gently blow air on bond for 5 seconds to spread it around before curing.

[@ypherrist2792]

According to Grossman's, air is lightly blown on primer for solvent to evaporate

wees kritisch over wat je ziet op internet ! denk dat de 1e flow laag goed uitgehard is ? Hierbij mijn tips voor een goede kl-II restauratie : 1) efficiënt omgaan met materiaal , je ziet hoe onnodig veel composiet was verspild op deze video. 2) Probeer eest de cervicale afsluiting & randlijst goed te herstellen. Nu heb je als het ware een klasse I caviteit. Ga door alsof je een klasse I gaat restaureren ( laag gewijs ! ) 3) Goed modelleren = minder afwerken. Probeer dit binnen 30 mins af te maken :) In de praktijk besteed je normaal gesproken rond 30 mins aan klasse II ( prep+ rest) ! heel veel succes.

[@marcofontainhas7791]

You need some water molecules, most solvents on the adhesive are hidrophilic

[@iraxican]

1. although Enamel should be dry, Dentin should be kept wet before applying bonding because the bonding components are hydrophilic so they displace the water inside the dentinal tubules and create a hybrid layer. 2. You're supposed to blow gentle air on bonding until there is no material wiggling, this is done in order to evaporate the solvent.

Nice music😉 Thank you for your time and effort😇

[@lannyrubindds7071]

Great video Thanks. one quick question. at the end when you went in with the round bur was that on a slow speed or high speed handpiece??

[@zlenkodmd]

I once did and my instrument got stuck inside composite lol. Everything ended well.

[@melvoulgaropoulos6707]

Try using a disc next time to shape your interproximal contact. The lingual embrasure has not been opened enough.

[@MyGabriella21]

Such a waste of material;/

Nope. Not good

[@yeahperry]

what matrix system is being used in this video?

[@emaxdentistry8747]

triodent matrices

[@rakeshyadav-ri4vn]

there also a product from dentsply matrix

[@mouhammadjawad8371]

Sectional matrix system.

[@zolimak927]

Oh! Thought it was Palodent Plus

[@tmary98]

We have something similar and we call it a V3 ring!

[@ahmadsaeed3157]

Can anyone name the instruments used during the entire procedure ?

[@jaganjthaliath5073]

thank you

Thanks a lot !!

[@viet4life714]

How long did it take you to prep it?

[@moonmoon-r3r]

No thanks, very sloppy job in my opinion
