How to Use This Calculator
- Enter Location (1-3), Abutment condition (1-3), and Distal extension (0/1).
- Set Aesthetic demand (1-3).
- Review the Attachment type (1-3) result.
- 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
- Identify Input Parameters4 parametersLocation (1-3) = 1, Abutment condition (1-3) = 1, Distal extension (0/1) = 1, Aesthetic demand (1-3) = 2 = 4 input(s) provided
- Calculate Attachment type2 = 2
- Calculate Retention forceRetention force8 = 8
- Calculate Aesthetic scoreAesthetic score95 = 95
