Class III Composite steps:
Acid etch → rinse & dry
Prime → air dry
Adhesive → cure w/ 18J light
Place composite & cure after each increment
A2D = dentin
A1E = enamel
Pull-through = lingual → facial
Cure F and L
Finish and polish
Finishing = shaping, contouring, and smoothing the resto
Polishing = imparts the shine/surface luster


Contouring Proximal
Mesial surface → medium-orange SOFLEX disc @ 4500 RPM
Gingival embrasures → no. 12 blade
remove small amounts at a time to avoid chipping
Blade dulls quickly
Contouring Lingual
Carbide football/egg to remove → excess and contour lingual @ FG 6000 RPM
Carefully use SOFLEX disc if needed @ margins
Contour, finish, and polish from composite TOWARD the tooth
avoid forming flat/concave contours in resto/tooth structure


Polishing cups order

Green → blue → grey (no water)
Green = Jiffy Polisher
removes roughness left by diamond bur
Blue = Gloss Plus Polisher
further smooth the resto
Grey = HiLuster Plus
obtain high gloss
