Heliosit Orthodontic is a light-cured, highly translucent luting composite for orthodontic brackets (made either of metal or ceramic material).
After the enamel has been etched with phosphoric acid (37%), Heliosit Orthodontic is applied to establish a sound bond (metal and ceramic surfaces have to be pre-treated according to manufacturer’s directions).
The monomer matrix consists of urethane dimethacrylate,Bis-GMA and decandiol dimethacrylate (85 wt%). The filler consists of highly dispersed silicon dioxide (14 wt%). Additional contents are catalysts and stabilizers (1 wt%).
- Cementation of brackets in orthodontics
- Flexural strength: 80 MPa
- Bond strength of brackets on etched enamel:ceramic: 10 MPa, metal: 12 MPa
- Store at 2–28 °C / 36–82 °F
Direction to Use
- Step 1.
Clean enamel surface thoroughly.
- Step 2.
Isolate with cotton rolls and blown air.
- Step 3.
Etch enamel surfaces (e.g. with Total Etch for 30 to 60 seconds). Heavily fluoridated enamel may have to be etched longer.
Note: The etched enamel surfaces should be of a white chalky appearance. If this is not the case (e.g. because of contamination with saliva), etch again for another 30 seconds.
- Step 4.
Rinse and dry the etched enamel surfaces thoroughly.
- Step 5.
Apply Heliosit Orthodontic to the undersurface of the metal bracket cleaned according to the instructions of the manufacturer.
Note: Prepare ceramic brackets according to the instructions of the manufacturer.
- Step 6.
Position the bracket on the tooth surfaces. Cure with a halogen light (e.g. Astralis) from the cervical for 20 seconds to fix the bracket in place. For complete polymerization, cure for another 20 seconds from the incisal. After the second polymerization phase, the bond strength of the material is high enough to allow the removal of excess and the exertion of immediate stress required for correcting the positioning of teeth.
- No dosing or mixing required
- The light-cured material allows the bracket to be conveniently positioned on the tooth surface without any time constraints
- The exceptional translucency of the material enables a thorough cure when it is exposed to polymerization light
