Composite Polishing Burs and Discs in Egypt

How to Polish Composite Resin Step by Step

• Finishing vs Polishing -- The Difference — Finishing removes excess composite and shapes macro-anatomy using coarse burs and discs; polishing removes micro-scratches to achieve gloss. Never skip the finishing stage -- using fine polishing points on an unfinished surface embeds composite irregularities and increases surface staining susceptibility.
• Coarse to Fine Sequence — Always follow the sequence: coarse (shape) -> medium (smooth) -> fine (pre-polish) -> superfine/ultra-fine (gloss). Skipping grits or jumping straight to fine polishing leaves subsurface scratches that appear as a milky, dull surface under operatory light.
• Sof-Lex Discs — Sof-Lex aluminium oxide discs are the gold standard for posterior composite finishing and anterior labial surface polishing. Use at slow handpiece speed (10,000-15,000 rpm) with light pressure and constant movement -- sustained pressure on one spot creates heat that can debond the restoration.
• Silicone Polishing Points and Cups — Silicone impregnated polishing points, cups and wheels are used for interproximal, sub-gingival and concave composite surfaces. Silicone points embed abrasive particles progressively -- they self-refresh and do not require lubricant, unlike diamond polishing pastes.
• Diamond Composite Burs — Fine and ultra-fine diamond burs shape cuspal anatomy and proximal contours before disc polishing. Use 30-micron fine diamonds for anatomy definition after bulk shaping, then transition to disc and silicone polishing for the final gloss.
• Polishing Pastes — Composite polishing pastes (used with a prophy cup) give the final high-gloss surface after silicone point polishing. Apply polishing paste as the last step -- it is a maintenance and finishing tool, not a substitute for the disc and silicone point sequence.

Composite Polishing Systems at a Glance

How to Finish and Polish Composite Resin

1. Check occlusion first with articulation paper -- remove premature contacts with a fine diamond bur.
2. Shape anatomy using a 12-blade carbide finishing bur or coarse polishing disc.
3. Progress through medium, fine and superfine Sof-Lex discs or silicone points at slow handpiece speed.
4. Use silicone cups or points for interproximal and concave surfaces inaccessible to flat discs.
5. Finish with a composite polishing paste on a prophy cup for the final high-gloss surface.
