Harvard Self-Bond 5ml = 8.5g 7TH BONDING SYSTEM
- Harvard Self-Bond is a simple to use. 5ml = 8.5g
- self-etching light curing
- one component adhesive.
- It ensures a strong bonding of composites to enamel and dentin.
- No extra etching necessary
- Only one layer necessary
- Easy application
- Hydrophilic for wet-bonding technique
Harvard Self-Bond is designed for bonding of light cure composites to enamel and dentin
1. Cavity preparation
After isolation (best with a rubber dam) prepare the cavity with minimal tooth reduction.
Margins should have a slight (0.5-1.0 mm) bevel placed in the enamel to increase the surface area for greater bond strength.
2. Pulp protection
Cavity floor of deep excavations should be covered with a thin layer of calciumhydroxide material (e.g. Harvard CalciumHydroxide).
3. Application of Harvard Self-Bond
Apply Harvard Self-Bond with a brush onto the slightly moist enamel and dentin surfaces for 30 seconds with agitation.
The material should build a homogeneous layer. Air thin gently for 10 seconds to remove the volatile components and to disperse the adhesive. Then light cure with a suitable dental light unit for 20 seconds before placement of a composite.
4. Placement of the restorative
Apply the restorative material according to the instructions of the manufacturer.
Best results are obtained with application of a thin layer of a light cure flowable composite (e.g. Harvard RestoreFlow) followed by the application of a moldable composite (e.g. Harvard Restore) according to the instructions.
· Avoid contact with skin, mucous membrane and eyes.
· Unpolymerized Harvard Self-Bond may have an irritant effect and can lead to sensitization against methacrylates.
· Commercial medical gloves do not protect against the sensitizing effect of methacrylates.
