OptiBond Solo Plus is a single-component dental adhesive designed for both direct and indirect bonding applications. It is 15% filled with the same 0.4 micron filler found in the Kerr Point 4 composite.

The filler not only reinforces the hybrid zone but also penetrates the dentin tubules, creating a true "structured bond" not found in unfilled or even "nano" filled adhesive systems.

This unique technology provides the highest level of protection against microleakage, while sustaining high bond strengths to a variety of surfaces.

It is the most used 5th generation bond in the UK, same as ExciTE F, Prime and Bond NT and iBond Total Etch.
