Recommended NeoDiamond Shapes for Crown & Bridge Preps
Highest Rated Zirconia Cutter
Rated as best cutting and lowest cost for Zirconia crown removal by an independent research test of 14 competitive burs. Select grit ensures smooth, efficient performance.
Chamfers are the preferred preparation for Porcelain Fused to Metal (PFM) crowns. Restorative material brands include Captek®, In-Ceram® and Wol-Ceram.®
Modified Chamfer Preparations
Modified Chamfers are the preferred preparation for CAD/CAM alumina based crowns. Restorative material brands include Procera® and Sirona Cerec inLab®.
Shoulders are the preferred preparation for full porcelain crowns. A flat-end taper diamond creates a shoulder with a sharp internal angle. This finish line can be modified to a chamfer or bevel, or refined with end-cutting diamonds.
Modified Shoulder Preparations
Modified shoulders, with a rounded internal angle, are the preferred preparations for the following types of full coverage crowns and bridges:
1) Pressable ceramic (IPS Eris®, IPS Empress®, OPC®, Finesse,® All-Ceramic®, Authentic®).
2) Zirconia-based (Cercon®, Lava®, Everst®, DCS Smart Fit®).
3) Fiber-reinforced or composite-based (Belleglass HP®, Sculpture/FibreKor®, ArtGlass®, Targis/Vectris®).
Recommended Shapes for Today's Popular Esthetic Procedures.
Prepare and finish repeatable, predictable esthetic laminate veneers. Using selected NeoDiamond shapes, clinicians are provided an excellent method of consistently following fundamental preparation protocols for adequate space and proper marginal placement for quality restorations.
Produce simple, consistent tooth preparations that conform to specific guidelines of the Cerec CAD/CAM system, using selected NeoDiamond shapes. Create proper anatomical occlusal morphology—essential for excellent Cerec restorations using selected finishing shapes.
Excellent, Economical Finishing Diamonds
Smooth the surface of composite, glass ionomer and porcelain restorations. Extremely uniform coating of 30 micron grit allows smooth cutting, without vibration or damage to composites, glass ionomers or porcelain. Use with minimal pressure, adequate water and consistent wiping motion.
Cutting Zirconia Crowns
The NeoDiamond Z-Class 1116Z is ideal for zirconia crown removal.
Use this diamond on the BruxZir®, Incoris TZ1 Cerec®, and Lava® crowns. Use shape 0118M for endo access.
Cutting Lithium Disilicate Crowns
These ceramic crowns are made by E.max®, Cerec, and Sirona®. A coarse diamond is recommended to cut through the material.
Cutting PFM Crowns
To remove porcelain fused to metal crowns, use a coarse diamond to cut through the porcelain layer. Then use a carbide metal cutter, NeoMax2 to cut the metal and remove the crown.
