Ormco EtchFree Bonding system: Introducing the next generation of bonding, inspired by nature

The Ormco EtchFree Bonding system adapts the technology gleaned from nature and uses it to create a new approach to bonding. This approach removes the etching step and thus the need for phosphoric acid as the active ingredient for prepping the tooth’s surface.

The system creates an effective bond by using three bonding components: EtchFree Bonding Primer, Ortho Solo bond enhancer and EtchFree Adhesive.

While typical etchants demineralize the enamel surface, EtchFree Bonding Primer uses a proprietary monomer inspired by proteins found in marine mussels to chemically prepare the tooth surface. This monomer cross-links with itself and other polymers in the system to form a matrix of co-polymers with specific adhesion properties.¹

The EtchFree Bonding system requires no acid etching mechanism to create clinically successful bonds in orthodontic cases and doesn’t damage the tooth surface. That is because the co-polymers in the EtchFree Bonding Primer bond instantly to the calcium ions in hydroxyapatite while remaining impervious to moisture. These ionically bonded polymer groups remain active and available for following resin adhesive steps.

Scanning electron microscope (SEM) images show that EtchFree Bonding Primer is less aggressive than self-etch products containing phosphoric acid. This helps preserve the natural surface of the tooth and presents a superior alternative over current etch and self-etch products when it comes to enamel health.

Dental and orthodontic bonding techniques and technology have been long overdue for innovation. With the help of nature, Ormco EtchFree rethinks how we approach orthodontic bonding without the acid etching technique that has remained mostly unchanged for decades.

EtchFree Bonding has been shown to significantly reduce procedure time, improve the patient experience, score high satisfaction by clinical staff and deliver overall improvements to clinical outcomes in orthodontic applications. EtchFree Bonding provides a chairside solution for orthodontists seeking to optimize workflow and minimize risks on bonding day.
