Structural reserve declines over time.
The Card
One model. One card.
Every SDF model is captured as a single collectible card — its identity, its lens, its tension. Hover to feel the foil.

Inside the Model
Read the diagram.
The card names the idea. The diagram shows how it behaves over time, what reduces structural reserve, and what every clinical decision is really weighing.

SDF Doctrine

Teeth do not fail randomly. They lose structural reserve over time.
Explanation
As enamel wears and internal stress accumulates, the tooth becomes more vulnerable to fracture and decay.
Key takeaways
- Teeth weaken gradually, not suddenly
- Early intervention preserves structure
- Waiting increases complexity of treatment
