eBrace Lingual Bracket System is custom made. The precise brackets and archwires are respectively made by the advanced prototyping machines and wire bending robots. Each set of appliance packed in the box is directly delivered to one doctor and designed only for a particular patient. The brackets can be bonded in one time with the help of transfer tray. Every aspect of the treatment has been considered and users can even see the result before the treatment.
Characters of eBrace：
Completely invisible and esthetic
Efficient treatment speed
Comfortable with small and arc bracket body
No damage to the appearance
Three kinds of bracket materials for option
Manufacture of eBrace:
1. Impression-Taking and Set-up
Clinically, a two-phase silicone impression is first taken. The casts produced from this impression are used to prepare an individualized ideal set-up. Set-up can be made by manual and virtual.
2. Scanning the Tooth Surface with a 3-D Scanner
The set-up is digitized at the orthodontic practice with a high-resolution 3D scanner. The outcome of the scanning is a compound surface consisting of more than 100,000 minute triangles.
3. Generating Individualized Bracket Bases
In contrast to existing lingual brackets, individualized bases are generated on the lingual surfaces of the teeth for the brackets presented here. The pad surfaces are generated large enough to provide even greater bonding strength and exact form-fit properties. The subsequently defined thickness is 0.3-0.5mm, depending on the alloy used and e·Brace mesh designed to cast out together.
4. Manufacturing the Bracket Body
The integrated bracket body, comprising the slot, wings, hooks, and wire-support structures, is designed with CAD/CAM software. Compared with conventional lingual brackets, the lingual bracket has an extremely low profile, which allows a simplified ligation procedure without compromising control over tooth positions. Digital libraries allow the clinician to select various features of the appliance, such as vertical or horizontal insertion of edgewise or ribbon archwires.
5. Manufacturing the customized lingual archwires
The highly complex geometries resulting from this individualization are bent and programmed into the archwire by state-of-the-art bending robots. Superlastic archwires are reprogrammed during the bending process and heat treatment meet stable shape. This is the only way of ensuring full manufacturing accuracy even in the anterior region where the archwire has a characteristic, platform shape.
