SDF · Framework Logic

Aging patternshow dentistry changes over decades.

Aging patterns explain how teeth, bone, and prior dental work change over time — often quietly. Within the Structural Decision Framework (SDF), aging is not “background.” It changes structure, force tolerance, timing windows, and long-term stability.

How SDF evaluates aging patterns
Structure
Enamel thins, dentin fatigues, bone remodels, and old margins weaken. Options narrow when structure is gone.
Force
The same bite forces become more damaging when support is reduced and contacts drift into overload.
Timing
Early intervention can preserve options. Late intervention often becomes damage control with fewer predictable paths.
Long-term stability
Stability becomes less about “perfect dentistry” and more about predictable load, maintenance reality, and failure risk.
What changes over decades
  • Teeth become thinner, not stronger.
  • Microfractures accumulate quietly and then show up “suddenly.”
  • Old restorations change load pathways and create stress risers at margins.
  • Bone is always remodeling, especially after extractions or long-term missing teeth.
  • Force patterns drift when molars are lost, often pushing load forward to the front teeth.
Why what works at 35 can fail at 75

Aging doesn’t just raise risk. It narrows options. The same cavity, crack, or worn edge can behave very differently depending on remaining structure, force direction, and how much fatigue has already accumulated. In SDF, we treat aging as a first-class variable because it changes predictability and the timing window for preserving long-term stability.

Applied aging scenarios

These scenarios apply aging patterns to real decisions — where options narrow, risk changes, and timing becomes the difference between preservation and damage control.
