Finishing and Polishing

 

1. Unpolished Integrated Abutment Crown.

2. Use Superior grade Diamond Fine Cut Carbide bur with double blue band to remove entire superficial layer.

3. Use a soft white silicone disc to finish shaping and cutting the surface.

4. Use a super-fine grade carbide bur to further prepare the surface.

5. Use the pink silicone polishing disc alternating back and forth with the white silicone disc until the desired anatomical contouring and surface texture is attained.

6. Use the nylon bristle brush to cut and smooth the surface.

7. Polishing is achieved with a soft bristle brush and polishing compound using slow circular motions. Keeping the crown wet during polishing will prevent overheating.

8. Complete the polishing process with a buff cloth wheel.

9. Final Integrated Abutment Crown.

 

 

 

Note: Do not substitute a glaze for polishing. Glazes only last 6-8 months intra-orally. For permanent shine it is essential that the crown be polished mechanically.

 

Keys to Success

  • Remove entire superficial layer prior to polishing for long-term maximum aesthetics.
  • Polish at slow speeds keeping the crown wet to avoid heating of material.
  • Never use glaze material.
