How to Use This Calculator
  1. Enter Number of implants, CBCT voxel size (mm), and Intraoral scan accuracy (mm).
  2. Set Guide type (1-3).
  3. Review the Total system deviation (mm) result.
  4. Use Angular deviation (deg) and Apical deviation (mm) to inform your decision.

How the result changes with CBCT voxel size (mm)

What each input means

Number of implants
Number of implants in the surgical guide.
CBCT voxel size (mm)
CBCT scan voxel size (smaller = higher resolution).
Intraoral scan accuracy (mm)
Manufacturer-stated accuracy of intraoral scanner.
Guide type (1-3)
1 = conventional lab, 2 = 3D printed, 3 = milled.

What each result means

Total system deviation (mm)
Cumulative positional error from all sources.
Angular deviation (deg)
Expected angular deviation of placed implant.
Apical deviation (mm)
Expected deviation at the implant apex.
Safety zone (mm)
Minimum distance to maintain from vital structures.
Fabrication time (days)
Business days for guide fabrication.
Est. guide cost ($)
Estimated cost for the surgical guide.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Number of implants = 2, CBCT voxel size (mm) = 0.2, Intraoral scan accuracy (mm) = 0.05, Guide type (1-3) = 2 = 4 input(s) provided
  2. Calculate Total system deviation
    Total system deviation
    0.26 = 0.26
  3. Calculate Angular deviation
    Angular deviation
    4.1 = 4.1
  4. Calculate Apical deviation
    Apical deviation
    1.08 = 1.08
