What makes "survival" special?
- Outcome is time-to-event (implant failure time, time to caries recurrence, etc.).
- Some subjects are censored (event not observed by study end).
- Kaplan-Meier estimates survival as a step function.

Real Dental Scenario: Implant Survival Over 60 Months
A clinic placed 50 dental implants and followed them for up to 60 months. Some implants failed (turned red), some patients were lost to follow-up / censored (turned gray), and the rest survived (remain green). Watch the study unfold, then see the Kaplan-Meier curve built step-by-step.

Dental example
Implant survival is often reported with Kaplan-Meier curves, and groups (e.g., smoker vs non-smoker) can be compared using the log-rank test.
