Planes of reduction for the mandibular molar

Burr used for occlusal reduction is a 1 mm bur (round)

  • the purpose of using only a 1 mm burr when you need 1.5 -2 mm of clearance is so that you can reduce, then slowly but surely finish and get it to the right clearance

Steps:

B- Plane

  • Start by reducing 1 aspect of the mesiobuccal cusp on the b-plane
  • *Utilize the burr as a cutting and measuring tool simulatenously *
  • tip the cusp about 35 degrees to the horizontal (the steepness of the incline to the triangular ridges)
    • this helps to try and reduce the ridges uniformly

A- plane Functional cusp bevel

  • this helps to parallel the opposing inclines

Polishing

Use the flame burr to round off all sharp edges
