Finishing and Polishing of Composite Restorations

Question 1

Finishing

Answer 1

Process of removing surface defects or scratches created during the contouring process through the use of cutting or grinding instruments or both

Question 2

Polishing

Answer 2

Process of providing luster or gloss on a material surface

Question 3

Carbide burs and diamond points

Answer 3

Carbides
1) Cuts by pulverizing
2) Resists clogging
3) But tends to dull out faster than diamond

Diamonds
1) Cut faster
2) Light touch for optimal efficiency
3) Long lasting
4) Can easily cut tooth by error

Question 4

Carbide Burs

Answer 4

Fluted Carbide burs
1. 8,12, 16, 20, and 30 fluted carbide burs in various shapes available
2. The fewer the flutes the more aggressive is the cutting
3. We use 12 fluted burs to finish the restoration

Question 5

Diamond Burs

Answer 5

1. The primary purpose for finishing diamonds is to contour the composite restoration, especially microfilled composites which are prone for surface micro cracks.
2. They come in various grit size ranging from 5 to 60 microns
