How to Use This Calculator
- Measure recession depth (mm) from CEJ to gingival margin and recession width (mm) mesiodistally.
- Enter the number of sites requiring grafting.
- Set the Miller recession class (I–IV) to indicate prognosis for root coverage.
- Review Graft Dimensions (mm), Donor Site Size, and expected root coverage percentage.
- Use graft dimensions to harvest the correct size connective tissue graft from the palate.
How the result changes with Recession depth (mm)
| Recession depth (mm) | Total graft area (mm²) |
|---|---|
| 1.7 | 47 |
| 3.45 | 65 |
| 5.55 | 86 |
| 7.3 | 103 |
What each input means
- Recession depth (mm)
- Vertical depth of gingival recession from CEJ.
- Recession width (mm)
- Mesiodistal width of the recession at the CEJ.
- Number of sites
- Number of teeth with recession requiring grafting.
- Miller class (1-4)
- Miller recession classification: I-IV.
What each result means
- Total graft area (mm²)
- Total connective tissue graft area needed.
- Graft length per site (mm)
- Required graft length per recipient site.
- Graft width per site (mm)
- Required graft apicocoronal dimension.
- Expected root coverage (%)
- Predicted percentage of root coverage based on Miller class.
- Expected coverage (mm)
- Predicted root coverage in millimeters.
- Est. total cost ($)
- Estimated total grafting cost.
How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersRecession depth (mm) = 3, Recession width (mm) = 4, Number of sites = 1, Miller class (1-4) = 2 = 4 input(s) provided
- Calculate Total graft areaTotal graft area60 = 60
- Calculate Graft length per siteGraft length per site10 = 10
- Calculate Graft width per siteGraft width per site6 = 6
