How to Use This Calculator
  1. Enter Location (1-3), Abutment condition (1-3), and Distal extension (0/1).
  2. Set Aesthetic demand (1-3).
  3. Review the Attachment type (1-3) result.
  4. Use Retention force (1-10) and Aesthetic score (0-100) to inform your decision.

What each input means

Location (1-3)
1 = intracoronal, 2 = extracoronal, 3 = stud/anchorage.
Abutment condition (1-3)
1 = excellent, 2 = moderate crown height, 3 = short clinical crown.
Distal extension (0/1)
0 = bounded saddle, 1 = distal extension (free-end).
Aesthetic demand (1-3)
1 = low, 2 = moderate, 3 = high aesthetic requirement.

What each result means

Attachment type (1-3)
1 = intracoronal rigid, 2 = extracoronal resilient, 3 = stud.
Retention force (1-10)
Relative retention force scale.
Aesthetic score (0-100)
Aesthetic concealment rating.
Maintenance interval (months)
Expected interval between component replacements.
Insertion complexity (1-3)
Path of insertion difficulty.
Est. lab surcharge ($)
Additional lab cost for precision attachment.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Location (1-3) = 1, Abutment condition (1-3) = 1, Distal extension (0/1) = 1, Aesthetic demand (1-3) = 2 = 4 input(s) provided
  2. Calculate Attachment type
    2 = 2
  3. Calculate Retention force
    Retention force
    8 = 8
  4. Calculate Aesthetic score
    Aesthetic score
    95 = 95
