The Occlusal Reduction Bur

The Occlusal Reduction bur, developed by Dr. Athas Kometas, DMD,
is a dental diamond bur that allows for precise occlusal reductions.

The bur is useful in occlusal reduction and lingual reduction by acting as a router of the occlusal surface. Its coarse diamonds result in a dental bur that quickly reduces the occlusal surface of teeth.

Occlusal reduction burs are available in 1.5mm, 1.8mm, 2.0mm, 2.2mm and 2.4 depths that correspond to proper coclusal reduction for various restoration materials.

A 1.0mm bur is also available for maxillary anterior palatal reduction.

The Occlusal Reduction Bur is a patented diamond bur design that allows access to the pits and fissures of the tooth from a vertical orientation.
The bur has a unique angled stop that limits the bur at the designated depth. A cross-hatched pattern is formed on the occlusal surface that when connected yields a perfect inclined plane reduction.

The bur is available in 1.5mm, 1.8mm, 2.0mm, 2.2mm, and 2.4mm depths corresponding to proper occlusal reduction for various restorative materials. A 1.0mm bur is also available for maxillary anterior palatal reduction.

Directions For Occlusal Reduction & Crown Preparation

I. Select the appropriate occlusal reduction bur for the restorative material.

1.5mm Green	–	Gold Crown
1.8mm Orange	–	Short Clinical mandibular premolar PFM Crown*
2.0 mm Yellow	–	All Ceramic, Captek, Cerec & PFM Crowns*
2.2 mm Blue	–	Long Clinical PFM Crown*
2.4 mm Red	–	Used to level occlusal plane on a superupted tooth

*Ideal porcelain fused to metal is 1.5mm to 2.00mm of porcelain and the coping thickness.

II. Start the depth grooves in the facial groove and extend into all fissures. Keep the ORB perpendicular to the external surface of the tooth for greatest accuracy. Allow the self-limiting feature to touch the occlusal surface and then push the bur laterally. Place extra depth grooves if possible from cusp tip to cusp tip, overlapping the functional cusp.
III. Use your preferred axial reduction bur to remove any remaining occlusal tooth structure to achieve the ideal inclined plane reduction Many dentists use the ORB to remove the remaining tooth by lightly “painting away” the tooth structure between the depth cuts keeping the bur perpendicular to the external tooth surface.
IV. Finish the axial reduction and pack a small retraction cord If no build-up is necessary, pack a secondary cord and proceed to impression and temporization.
