1. Begin with a slice cut in the interproximal area, using the long axis of the bur. Retract tissue with retraction cord after the slice cut.
2. Reduce the incisal edge by 1.5 – 2.0 mm, angling the diamond toward the lingual to stay parallel with the incisal line.
3. Prepare the labial surface by cutting lateral guide grooves 1.0 mm deep to guide the depth of the cut.
4. Reduce the labial surface depth to match the lateral guide grooves.
5. Prepare the labial and lingual cervical area, cutting from the lowest point of the cervical scallop mesially and distally on both surfaces. Ensure sufficient reduction in the center of the labial and lingual surfaces, avoiding excessive reduction in the interproximal subgingival cervical areas.
6. Prepare the lingual space, being cautious not to cut too much of the axial lingual wall.
7. Free enamel at the cervical area and prepare the shoulder margin. Smooth and finish the enamel, ensuring the bur is placed vertically on the shoulder margin surface and moved in the direction of rotation.
8. Complete the preparation by envisioning the final shape while cutting.

Premolar (1st Bicuspid) Preparation:

1. Reduce all four surfaces of the premolar, allowing for a slight undercut following the lingual inclination. The bur, correctly positioned against the occlusal plane, will tip toward the buccal surface.
2. Reduce the apex of the buccal cusp, following inclined plane angles.
3. Utilize premolar anatomy for the occlusal surface, similar to an anterior preparation.
4. Create broad mesial and distal pits in the occlusal surface, reducing toward each interproximal direction.

Upper Molar Preparation:

1. Reduce the occlusal surface to create space, using the bur’s top shape to cut the central groove and shape the side areas for crown pits.
2. Employ the nipple part of the bur top to smooth and finish the overall edge of the occlusal and axial angle.
