How to Use This Calculator

Enter defect depth (mm) and defect width (mm) from probing and radiographic measurements.
Set the number of remaining bony walls (1, 2, or 3) for the intrabony defect.
Enter the number of defect sites to be grafted in this procedure.
Review Graft Volume (mm³ and cc), recommended graft material quantity, and membrane size.
Order graft material based on the calculated volume plus a 10–20% overage buffer.
