The SonicFill handpiece delivers sonic energy in order to make composite resin flowable and simple to place. Once the energy is removed, the resin becomes quite firm and easy to sculpt.
What’s good about it
Its biggest advantage is the ability to bulk fill cavities very quickly. It will set with a curing light as long as it’s not more than about 5mm deep. The composite material and tooth are prepared as normal and, depending on your preference, mechanical locks can be put in place or you can rely completely on adhesion.
It is a very quick system which means there is less chance of moisture contamination. When a patient is forced to keep their mouth open for long periods because you’re adding layers of material, there’s a risk of body fluids compromising the restoration.
It’s also very adaptable. The material is easy to trim and work once the sonic energy has been released. It’s the closest thing I’ve seen to a ‘white amalgam’. Patient reports of post-operative bite or cold sensitivity are extremely rare.
The SonicFill easily fits onto a high-speed handpiece connector which, in my case, is a KaVo. It makes the whole procedure, from placing the bonding agent to finishing the restoration, much quicker.
What’s not so good
In terms of aesthetics, the composite resin is acceptable but the range of shades is limited to the light end of the spectrum. I only use it in posterior teeth and would not use it in anterior teeth. Also, if you decide to bulk fill a very large cavity (I still layer these) then there’s a risk of marginal discrepancies and join line issues. Joining lines between layers can sometimes result in staining on review.
