About interproximal strips
An interproximal strip is the cutting grade, used to take material off the contact between two teeth. Published work reports that reducing enamel between teeth raised surface roughness whatever the instrument used, and that the oscillating metallic strip gave the lowest roughness of those tested. The same work lists the type and grit size of the abrasive coating, the rotational speed and the operator control over the instrument among the factors behind the roughness produced.
A strip is a thin flexible band coated with abrasive, pulled through by hand between two teeth where no rotary instrument fits. The FDA names the polishing agent strip in its Class I list of abrasive devices and accessories (21 CFR 872.6010). Published work on reducing enamel between teeth lists the available systems as hand-held abrasive strips, tungsten carbide or diamond burs, and powered systems such as mechanical oscillating disks or strips. One kind used in that work is described as a double-sided metallic electroplated abrasive strip 6 mm wide.
A strip is also used to adjust a restoration already in place: published work describes a diamond strip adjusting the tightness of a proximal contact by sawing a constant amount of material between the new restoration and the neighbouring tooth. The same work notes a strip can be used once the prosthesis is seated, so a contact can be adjusted even after cementation. It also gives the thickness of the diamond strips tested as roughly 65 to 75 microns, more than the 13 to 30 microns of shim stock.
How the types of strip differ
- Polishing strips — The finishing and gloss grades, used after the shape is set.
- Interproximal strips — Removes material from a contact; published work puts it alongside burs and discs as a stripping instrument, with polishing to follow.
- Polishers — Named for what it does rather than for the band it comes on.
What to look at when choosing a strip
Grit and backing: published work describes metallic electroplated abrasive strips and names the type and grit size of the abrasive coating as a factor in the surface produced.
Thickness: published work gives the diamond strips tested as roughly 65 to 75 microns thick, and notes that this makes them hard to insert between a restoration and the neighbouring tooth depending on periodontal health and tooth mobility.
One side or two: published work describes both single-sided diamond-coated discs and double-sided manual metallic strips in the same comparison.
Hand or handpiece: the same work ran the diamond-coated discs and the oscillating strips at 5,000 rpm with continuous water, while the manual strips were pulled by hand.
What follows: published work found polishing produced smoother surfaces in every group, and describes it as an indispensable step after reduction.
