The Blue View VariStrip is a contoured anterior matrix that provides the optimum curvature
and band height for virtually every anterior restoration. The 0.0020" thin plastic anatomical
strip is tapered from one end to the other. You can place the strip interproximally and then slide
it until the tooth height is perfectly matched. The precontouring easily re-creates the occlusogingival anatomy, avoiding flat embrasures.

Do you cut windows while doing Class IIIs? Otherwise how do you get contacts with the
GC in place? ■

Class III using Greater Curve and Activa. Easy-peasy. ■

When you blow out the contact, the most useful tip for me has been to turn a sectional
matrix band on its end and apply finger pressure from the lingual. Gets nice contacts and very
useful for diastema closure as well. Took Jason Smithson's Cosmedent anteriors class, which was
extremely helpful. ■

I assume you are having a hard time achieving a contact?
If your prep extends to the buccal, you need to bevel the margins of the buccal-facing portion of the prep. If you make the bevel margins irregular (starburst bevel) they will blend nicer.
(Prep from lingual.)
Control bleeding if necessary. #00 cord and or 2 percent lido 1:50k epi will be very helpful.
Nothing worse than having to redo a filling because of preventable contamination.
Place a matrix of your choosing. A basic Mylar will work in all situations. Fancier matrices
will reduce the skill needed to achieve reasonable contours and reduce your finishing time. Make
sure you are able to stabilize the matrix with a wedge and that the shape of the wedge does not
interfere with the shape of the contour you are trying to create. If the wedge is too tall, then you
can customize it with a bur to scallop the area under the contact.
Bleeding controlled, matrix properly wedged, bonding done, place a very small amount of
flowable inside the buccal margin of the box, wipe out most of it with a microbrush so there is
just a skim of the flowable left in the prep. Do not cure; inject-place a small amount of comp in
the box so it pushes that flowable buccal. Use a thin plastic to shape the comp on the facial of
the tooth to achieve the contour that you want and to cover the beveled areas you cut. Finish the
buccal contours before you cure. Be sure to not have this composite you injected/placed cover
the interproximal contact area; just build buccal to the contact. Cure this layer.
With the next layer you can build your contact. You can place an increment of comp in the
depth of the prep and work against the entire contact area, being sure to seal the incisal and
apical portions of the box. Before you cure, take an instrument and pull the composite toward
the contact and hold while curing. Your instrument will push through the composite but all
you have to do is not lock the instrument in the composite while curing. The larger amount
