Examined one of my original Sonicfills. It was a 2 years old large MO composite on #31. Margins were excellent except for a small hard pit void on an occlusal margin. I don’t blame that on the SonicFill material, I can be guilty of such a thing with any composite material. This is conjecture, but I believe the downward forceful pressure of the stamp technique will reduce the occurrence of marginal defects.
Creating a color blend for Class V’s can be frustrating. Give this technique a try. As an added bonus you will realize a stronger bonded restoration.
Using SureFil SDR flow as the first layer over the entire surface of the prep creates a low stress strong bond to dentin. The SureFil also creates a semi translucent layer which is covered by the Filtek Supreme Ultra “Body” layer. The result is a blended composite that reflects light much like the surrounding tooth structure. If the color is off, the result will still look respectable.
This is one of my earliest cases using the Greater Curve matrix. The Greater Curve matrix was introduced in 2006. Today, I would have built up the mesial and then squished the partial into a sea of soft composite.
Under a rubber dam positioning marginal ridges on multiple teeth can be tenuous. If the marginal ridges are too high there is a risk of adjusting through the contact when finalizing the occlusion. The Greater Curve system allows you to create contacts with depth. The risk of adjusting through the contact is mitigated.
A fun case. Overlapped anteriors can be difficult to restore. The Greater Curve system makes them more manageable.
