How to Use This Calculator
- Enter Defect size (cm²), Prosthesis type (1-4), and Retention method (1-3).
- Set Implant anchors.
- Review the Material volume (cc) result.
- Use Fabrication time (hours) and Patient appointments to inform your decision.
How the result changes with Defect size (cm²)
| Defect size (cm²) | Material volume (cc) |
|---|---|
| 11 | 8.8 |
| 36 | 28.8 |
| 65 | 52 |
| 90 | 72 |
What each input means
- Defect size (cm²)
- Approximate surface area of the defect.
- Prosthesis type (1-4)
- 1 = obturator, 2 = nasal, 3 = orbital, 4 = auricular.
- Retention method (1-3)
- 1 = adhesive, 2 = mechanical/undercut, 3 = implant-retained.
- Implant anchors
- Number of craniofacial implants for retention.
What each result means
- Material volume (cc)
- Estimated silicone or acrylic material needed.
- Fabrication time (hours)
- Estimated total fabrication time.
- Patient appointments
- Number of clinical appointments required.
- Retention score (0-100)
- Expected retention effectiveness.
- Prosthesis lifespan (months)
- Expected prosthesis service life.
- Est. total cost ($)
- Estimated total treatment cost.
