How to Use This Calculator
  1. Enter the Restoration M-D Length, B-L Width, and Height in millimeters to define the restoration envelope.
  2. Select the Block Material (Lithium Disilicate, Zirconia, or Composite/PMMA) — zirconia automatically applies shrinkage compensation.
  3. Set the number of Units to Nest to maximize block utilization across multiple restorations.
  4. Enter the Block Cost to calculate the Cost per Unit after nesting.
  5. Review the Recommended Block size, Material Utilization %, and Green State Length for zirconia milling.

What each input means

Restoration M-D Length
Mesial-distal length of the restoration.
Restoration B-L Width
Buccal-lingual width.
Restoration Height
Occlusal to margin height.
Block Material
Mill block material. Zirconia requires shrinkage compensation.
Units to Nest
Number of restorations to mill from one block.
Block Cost
Cost of the mill block.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Restoration M-D Length = 12, Restoration B-L Width = 10, Restoration Height = 8, Block Material = 1 = 6 input(s) provided
  2. Calculate Recommended Block
    Recommended Block
    C14 (14×12×18) = C14 (14×12×18)
  3. Calculate Cost per Unit
    Cost per Unit
    35 = $35
  4. Calculate Required Length
    Required Length
    13 = 13
  5. Calculate Material Utilization
    Material Utilization
    42.6 = 42.6
