I've been using VOCO products for years, too many to count, and I continue to be impressed with them. Today I'm excited to tell you about a new material the company has recently announced in the U.S. called GrandioSO 4U.
I was lucky enough to get some to try and test before it came to market and I can tell you this material is really impressive. The two things I'm most impressed with are the 4mm depth of cure (which I tested) and the shade matching. The 4mm depth of cure is a *true* claim and that depth of cure is achieved with a 10 second cure with a high powered light (>1100mw/cm2). That is paired with a 91% fill ratio and a 1.41% shrinkage. That means they polish extremely well and should hold up well over time. Many of the composites on the market that are deeper curing also have higher percentages of volumetric shrinkage. That can lead to microscopic breaks in the bond at the margin which contributes to marginal breakdown and recurrent decay. Also, most of the "bulk fill" materials available don't have the best aesthetics. GrandioSO 4U matches extremely well in the cases I've done and that low volumetric shrinkage is something I'm excited about.
We've seen some composites come to market in the last few years that have a "one shade works for everything" claim. Those systems are pretty good and I like them. However, everyone I've talked to has said that there are times that those materials don't blend as well as expected. That's been my experience as I've used them. Usually there is a decent match, but not always.
GrandioSO 4U makes shade matching more predictable with a "Cluster-Shade" system. This shade system covers all 16 of the Vita shades with just five shades. For those special cosmetic cases there are two extra shades of Bleach and Opaque.
VOCO makes amazing high quality products and I think you're really going to like GrandioSO 4U. Here is what the smart folks at VOCO have to say about it:
The most tooth-like universal composite in 5 shades with a 10 second 4 mm depth-of-cure
After 10 years of research and development, VOCO sets the bar higher by introducing GrandioSO® 4U, a 91% filled universal nanohybrid composite. It has tooth-like physical properties when it comes to elasticity, flexural strength, and thermal expansion behavior. Combined with a very low shrinkage of only 1.41% and a high wear resistance it raises the bar for longevity. Utilizing Visual-Transformation-Technology (VTT), GrandioSO 4U delivers a perfect balance of natural opacity for optimal esthetics and fast working speed with a depth of cure of 4 mm in 10 sec. Its Cluster-Shade system covers all 16 VITA® classical shades using just 5 shades, significantly streamlining inventory and shade selection. 30-50% less resin compared to classic composites gives GrandioSO 4U a superior non-stick consistency and makes the material extremely color-stable. 900% Al radiopacity sets a new standard for x-ray identification.
Unlike traditional layering composites or less aesthetic bulk fills, GrandioSO 4U delivers both simplified workflows and superior outcomes in a single material.
