Why use the Greater Curve system for composites?
Most interproximal composite techniques have one thing in common. Force teeth apart with a wedge and separating spring combination. Moving teeth to restore interproximal decay presents problems:
- Wedging teeth produces inconsistent contacts. Especially MOD's. One side tight- the opposite side not so tight. The dentist loses time redoing the contact.
- A wedge can create a contact with excellent buccal to lingual width but the wedge prevents a contact with depth. A thin marginal ridge contact appears clinically complete, but permits food impaction. Short teeth are particularly difficult. Simply not enough room for hardware.
- A wedge on anterior teeth yields straight line emergence contours resulting in unsightly black triangles. Furthermore, the traditional mylar strip – wedge combo are deplorable at achieving moisture control.
The Greater Curve system addresses these concerns. The solution is simple. Restore teeth in a neutral position. Eliminate the need for wedging.
- Hardware greatly simplified. A retainer and band is all that is needed.
- Build tight contacts with width and depth.
- Teeth with wide interproximal embrasures are easily restored.
- Fabricate anterior restorations with rounded emergence contours.
- Greater Curve hardware is minimal, hence you save money.
