- To obtain : ✔ Desired anatomy ✔ Proper occlusion ✔ Reduction of roughness, depth of gouges & scratches
- Polished surface should be smooth enough to be well tolerated by oral soft tissues and to resist bacterial adhesion & excessive plaque accumulation.
- When plaque deposits exist on restorative material surfaces, they should be easily removable by brushing & flossing.
⭐ BENEFITS ⭐
- BETTER GINGIVAL HEALTH:- A well contoured & polished restoration resists the accumulation of food debris and pathogenic bacteria. ✔ Food glides more freely over occlusal & embrasure surfaces during mastication.
- CHEWING EFFICIENCY:- Strength is improved especially in surfaces where more occlusal forces are applied.
- PATIENT COMFORT:- Patient can detect a surface roughness change of less than 1um ✔ Smooth restoration surfaces minimize wear rates on opposing & adjacent teeth.
- ESTHETICS:- Finishing and polishing aid in esthetics.
- TARNISH & CORROSION:- It can be reduced in metallic restoration.
- HYGIENE:- Smoother surfaces have less retention areas & are easier to maintain in a hygienic state when preventive oral care is practiced ( dental floss & toothbrush bristles )
