Body and Plunger
Body and Plunger

Esprit’s body and plunger are a true innovation. The body houses a stainless steel spring that is enclosed in a smooth, stainless steel sheath to protect the soft tissues from painful pinching. The end caps of the body are laser welded onto the body, making them completely durable. The plunger has a dual telescoping feature, and the plunger cap—like the end caps—is laser welded to provide ultimate durability.

Push Rod with Mesial Hook
Push Rod with Mesial Hook

The push rod is designed to prevent binding and contains a welded stop to prevent it from bottoming out. The mesial attachment has rounded edges for complete comfort, and it can be easily removed with a pair of Weingart pliers. Like other features of Esprit, the mesial hook is laser welded to provide outstanding durability. Plus the crimpable end is easy to clamp shut, and the cut angle prevents rolling while also eliminating the need for a comfort bend.

Distal Clip
Distal Clip

Esprit offers two types of distal attachment. Both attachments are easy to install and provide reliable treatment. The first type of attachment is the distal clip. The clip consists of the clip, two pins, a rotating “horn,” and a hook that can be bent. This bendable hook provides complete control, allowing the clinician to bend it in to restrict movement or bend it out to increase movement. The clip locks closed easily and stays closed during the entire treatment. It’s CNC machined for complete durability, and its rounded edges provide maximum patient comfort.

Euclid Pin
Euclid Pin

The patented Euclid pin gives the clinician an additional option when determining which type of distal attachment is best. The pin is easy to attach and requires no measuring or cutting prior to placement. It has a small notch that allows it to easily bend in only one spot, and it’s tapered, so it fits all headgear tubes. Like other Esprit components, the Euclid pin is CNC machined for precision and strength, and it’s smooth for patient comfort.

  1. OE Admin

    I have been using the Esprit Class II corrector for more than a year and I am very pleased with its performance. No breakages, adequate range of mandibular motion and a relatively low profile that is less likely to produce cheek discomfort among patients. – Dr. Carlos Flores Mir
