For Anterior Preparation

• Slice cut the interproximal area of the anterior tooth. Use the long axis of the bur. After slice cut, retract tissue with retraction cord.
• Reduction of incisal edge. Reduce the incisal edge 1.5 – 2.0 mm. Angle the diamond toward the lingual to stay parallel with the incisal line.
• Prepare the labial surface. Cut lateral guide grooves 1.0 mm deep on the labial surface to guide the depth of the cut
• Reduce the labial surface to the depth the lateral guide grooves
• Prepare the labial and lingual cervical area. Cut from the lowest point of the cervical scallop mesially and distally on the labial and lingual surfaces. Make sure to reduce enough in the
  center of the labial and lingual surfaces. Reduce enough in the center of the labial surface and
  not too much in the interproximal subgingival cervical areas
• Prepare lingual space. Do not cut too much of the axial lingual wall
• Free enamel at cervical area
• Prepare the shoulder margin. Smooth and finish the enamel at the cervical area
• Smooth and finish the shoulder prep by using the outside 1/3 of the bur cutting edge that is
  away from the long axis of the prep. Move the bur in the direction of the rotation
• Place the bur vertically on the shoulder margin surface, not parallel to the long axis of the tooth
  preparation
• Completed preparation. Imagine the final shape while cutting the preparation

For Premolar Preparation

• Preparation of lower premolar (1st bicaspid).
• Reduce the four surfaces of the premolar. A slight undercut will occur while following the lingual inclination of the premolar. The bur, when placed correctly against the occlusal plane, will tip toward the buccal surface.
• Reduce the apex of the buccal cusp following the inclined plane angles
• Utilizing the premolar anatomy. The occlusal surface is prepared similar to an anterior
  preparation
• To make broad mesial and distal pits in the occlusal surface, reduce toward each interproximal direction

For Molar Preparation

• Preparation of upper molar
• Reduce occlusal surface to create occlusal space. Use shape of the bur top to cut the central groove and to shape the side areas for the pits of the crown
• Use the nipple part of the bur top to smooth and finish the overall edge of the occlusal and axial
  angle
