When polishing composite restorations, what is the recommended progression of abrasives?

When polishing composite restorations, the recommended progression of abrasives is from coarse to fine. This approach allows for the effective removal of surface imperfections and achieves a smooth, polished finish on the restoration. Using coarse abrasives initially helps to eliminate any gross irregularities and effectively shapes the surface. As the polishing process continues with progressively finer abrasives, it refines the surface further, reducing scratches and enhancing the shiny appearance of the composite material.

Starting with a coarse abrasive is essential because it provides the necessary cutting action to address larger flaws. Following this with medium and then fine abrasives gradually smoothens the surface without risking damage to the restoration. This systematic progression is crucial to achieving a smooth, highly-polished finish that not only improves aesthetics but also contributes to the longevity of the restoration by reducing plaque accumulation and enhancing wear resistance.
