i've been using a wedge and matrix band and trying to push the composite against the band but then it seems like i just BARELY dont make contact. anyone have any tips on consistently getting good contacts?
 
I have a couple questions for you first:

1. Are you placing the wedge properly, I mean really jamming the wedge as far as you possibly can?

2. How much composite are you placing in the proximal box? Are you placing it in steps or filling the box all at once?

3. Are are you sure you're not placing the matrix band upside down? (silly but possible)


In regards to the second question, make sure you are placing it in increments and while you are curing the composite, place a composite instrument in the box and put pressure on the band against the adjacent tooth. Also, make sure that wedge is practically buried interproximally, just absolutely bury it in there, and don't use the smallest wedge.
 
Pre-wedging is also important. Learned this the hard way my 3rd year. Make sure you wedge the teeth apart while you are preparing the tooth. You get more seperation and thus much better contacts. Keep trying!
 
Burnish, or get a ring system.
 
Burnishing the matrix with a ball burnisher against the adjacent tooth helps me.
 
I pull the matrix band towards the adjacent tooth while curing each increment.
Burnishing helps also though it is not really necessary if you're using a ring system.
Is your wedge big enough? If you are still only working on dentoform teeth then you probably need a bigger wedge and wedge the heck out of it. Getting a contact is much easier in the mouth.
 
for us if we face problem such like that our instructor teach us something that when you start to fill the box with composite first of all you make a small ball of composite then polymer it after that we put the first layer on the gingival wall without polymerization then embed the ball on it and against the matrix and turn the light to set the composite on this position when you finish you already make a good contact need only to fill the gab and by this method you don't need to be afraid form loosing the contact

i hope i was clear enough

i've never heard about this technique before! how exactly do you determine the size of the composite ball?
 
its simple tech, the guide in deterring the size of composite ball is the cavity volume you don't need to measure it just by your imagination you made the ball
i hope it was clear
 
Ring system matrix bands, good wedging and burnishing the band (with ball burnisher or condenser) against the adjacent tooth work very well for me.

I use the same technique, it works great. Old school is best school 🙄
