Step 1: Isolation
Isolation in quadrants utilizing a clamp and rubber dam

Step 2: Preparation
Removal of old dentistry

Step 2: Preparation
After rendering cavity as caries-free, enamel margins are beveled

Step 2: Preparation
Cavity is etched, and a dentin-bonding agent is placed and polymerized for 30 seconds

Step 2: Preparation
Flowable composite is placed, then polymerized for 40 seconds

Step 3: Bonding
Composite resin is laid out in 2mm x 1mm increments in the light well of a composite heater

Step 3: Bonding
Resin carried to the cavity

Step 3: Bonding
Bend microbrush at desired angle to aid in ergonomics, and used in patting motion to condense resin

Step 4: Resin Build-Up
The dentin mass is modeled on a cusp-by-cusp bases, oblique layering and polymerizing each separate cusp to reduce “C-Factor” stresses

Step 5: Finishing
Enamel tints are applied. The enamel shade composite is built up. Each increment is polymerized for three seconds.

Step 5: Finishing
Initial and Final polishing

Result
Final restoration and esthetic integration
