As we know, bonding has become increasingly prevalent in today’s dentistry. While bonding is indeed here to stay it’s undeniably technique sensitive. The following are three simple universal steps we can use to greatly improve our predictability with bonding.
1. Read: Understand and follow the instructions for the particular system or systems you decide to implement. While most systems today come with very clear instructions, if something is not clear to you don’t guess; instead contact the technical support department of the manufacturer.
2. Isolation: When it comes to bonding, isolation is critically important. The better you isolate the better your results. The most predictable ways I’ve found to achieve excellent isolation are with a rubber dam, an Isolite or the Isodry system. While there are advantages to each of these, if you are not familiar with the Isolite or Isodry systems, I highly recommend them. In many cases these can be an excellent alternative to rubber dam isolation.
3. Keep the chemistry right: Bonding agents typically have more than one component in each container. It’s important to be sure to mix them up prior to use by inverting the container a few times. This will ensure a good mix and also minimize the formation of bubbles. In addition some of the components in our bonding agents are inherently prone to evaporation and this evaporation can alter their chemistry and thereby affect their performance.
To minimize this risk be sure to wait prior to dispensing them until you are ready to use them. Immediately put the caps back on after you dispense the needed amount. Another thing to consider for the best possible chemistry is to use a unidose version of your preferred system. Doing this ensures that you have fresh chemistry every time you open a new dose.
