Composite Attachment Finishing Burs (CAB) are exquisitely manufactured fine diamond burs that have been specifically engineered to provide rapid and accurate removal of excess composite resin after placement of attachments associated with clear alignment therapy. They are equally as effective in gently removing attachments with minimal enamel impact at the end of treatment.
The design and diminutive size allow the user to easily manoeuvre the bur around even the most delicate attachment shapes, ensuring that no residual resin is left on the enamel, which may impinge upon the seating of the aligner.
The burs are delivered in packs of 2 or 5, in 2 diamond head sizes 3.5mm and 6.0mm and 3 grits, depicted by the different band colours: blue, red and yellow:
- A Blue band bur for rapid reduction and removal of excess resin
- A Red band bur for initial finishing of the excess resin and ename
- A Yellow band bur for establishing a high polish of the enamel, to use for trimming and finishing attachments. After they have been placed and fully cured, identify any excess by visual inspection or by the use of ultraviolet LED.
Remove a blue CAB bur from the package with tweezers and place into a high-speed turbine using finger pressure only.
Select a size that allows the easiest access and maximum control.
Gently polish away the excess composite, trying to avoid touching the body of the attachment.
Once the excess has been removed, change to the red bur and polish the attachment-enamel interface.
Then swap to the super-fine yellow band bur and polish the enamel to a high lustre.
When utilising the burs for the removal of attachments at the end of treatment, take the blue CAB bur from the package with tweezers and place into a high-speed turbine using finger pressure only. Gently polish away the body of the composite attachment, until you get close to the enamel.
Once the body of the attachment has been removed, change to the red bur and polish the attachment completely away, back to the enamel surface.
Then swap to the super-fine yellow band bur and polish the enamel to a high lustre. The application of topical fluoride is highly recommended.
