ADDLER DENTAL LAB ZIRCONIA PEAR SHAPE BUR LOW SPEED 2.35 SHANK

A pear-shaped zirconia bur is a versatile tool in a dental lab, primarily used for:

1. Gross Reduction and Shaping: The wide, rounded body of the bur is excellent for removing large amounts of zirconia from a block or a milled crown. This is often the first step in shaping a restoration after it has been milled.
2. Contouring and Refining: The tapered tip allows for intricate detail work. This is crucial for refining the anatomy of a crown, creating precise occlusal (biting) surfaces, and carving detailed grooves and fissures.
3. Adjustments: It is used to make adjustments to the margins and contacts of a zirconia restoration to ensure it fits perfectly on a model or die.
4. Creating Retention: In some cases, the pear shape can be used to create retention features in the tooth preparation or the restoration itself, ensuring a secure fit.
