Peri-Implant Case Definitions (2017)
Peri-implant health, mucositis or peri-implantitis by the 2017 World Workshop case definitions, with or without a baseline record.
Open the calculator → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- Bleeding or suppuration on gentle probing
- Yes
- Baseline radiograph and probing record available
- No
- Without a baseline: deepest probing depth
- 7 mm
- Without a baseline: radiographic bone level
- 4 mm
Result: Peri-implantitis (no baseline): bleeding or suppuration on gentle probing with a probing depth of 7 mm (6 mm or more) and a bone level 4 mm (3 mm or more) apical to the most coronal part of the implant within bone.
The tool opens with these values already filled in. Replace them with your own.
What you enter
- Bleeding or suppuration on gentle probing
- Baseline radiograph and probing record available
- With a baseline: bone loss beyond initial remodeling
- With a baseline: probing depth increased
- Without a baseline: deepest probing depth
- Without a baseline: radiographic bone level
