How to Use This Calculator
- Enter the current clinical crown height (mm) measured from the gingival margin.
- Input the desired crown length (mm) needed for the restorative procedure.
- Set the biologic width (mm) — typically 2–3 mm of supracrestal tissue attachment.
- Enter the number of teeth requiring crown lengthening.
- Review Bone Removal Required (mm), Estimated Healing Time, and procedure complexity rating.
How the result changes with Desired crown length (mm)
| Desired crown length (mm) | Bone reduction needed (mm) |
|---|---|
| 5.6 | 3.1 |
| 9.6 | 7.1 |
| 14 | 11.5 |
| 18 | 15.5 |
What each input means
- Current clinical crown (mm)
- Current visible clinical crown height.
- Desired crown length (mm)
- Target clinical crown length after surgery.
- Biologic width (mm)
- Supracrestal tissue attachment (typically 2-3mm).
- Number of teeth involved
- Number of teeth requiring crown lengthening.
What each result means
- Bone reduction needed (mm)
- Amount of alveolar bone to remove.
- Soft tissue removal (mm)
- Amount of gingival tissue to remove.
- Procedure type (1-2)
- 1 = gingivectomy only, 2 = osseous surgery.
- Healing time (weeks)
- Expected soft tissue healing period.
- Wait for restoration (weeks)
- Recommended wait before final restoration.
- Est. total cost ($)
- Estimated cost for all teeth.
How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersCurrent clinical crown (mm) = 5, Desired crown length (mm) = 10, Biologic width (mm) = 2.5, Number of teeth involved = 2 = 4 input(s) provided
- Calculate Bone reduction neededBone reduction needed7.5 = 7.5
- Calculate Soft tissue removalSoft tissue removal5 = 5
- Calculate Procedure typeProcedure type2 = 2
