Universal Sealant and Bond Enhancer Ortho Solo™ is a universal sealant and bonding primer for use with light cure and chemical cure bonding systems. Ortho Solo’s hydrophilic property makes it moisture tolerant. Ortho Solo incorporates a bond-enhancing property designed to improve adhesion to the tooth at the adhesive interface. The glass filler is designed to act as a stress and shock absorber, helping prevent cracks that can lead to bond failures. No air-dry or light-cure step is needed. Includes a compound that displaces moisture, making the technique more forgiving when a dry field is inadvertently compromised.
