How Can We Help?

How do I close an open contact?

Ask yourself the following:-

Is the poor contact big enough to inject flowable?

If not use a high speed hand-piece to do a saucer prep on the proximal surface to open the gap then use one of the method below.   If yes, just  use one of the two methods that we recommend (see below).

Method 1: Place OVC Wedge, dry, apply bonding agent, dry, then inject flowable resin as deep as possible and manipulate with a fine instrument to ensure bubbles are released. Add more flowable or regular composite incrementally and then fully cure from all directions. Note: Do not use self etching bonding agents. Bonding agent will go onto the neighbouring proximal contact. Non self-etching bonding agents do not bond well to unetched enamel and can be prised apart with a flat plastic. This will enable flossing.
Use a high speed hand-piece to do a saucer prep on the proximal surface to open the gap. If yes: There are two methods that we recommend (see below).

Method 2: Alternatively, you can recover using a sectional matrix system such as the Dentsply Sirona Palodent Plus or Triodent V3 System. If required you can open the contact a little further so that you have better access. The composite will bond very well with the OVC.
