The Structural Decision Framework
The Structural Decision Framework (SDF) is a clinical decision model used to evaluate long-term dental outcomes before recommending irreversible treatment.
Many dental decisions focus on procedures.
We focus on long-term outcomes.
We focus on long-term outcomes.
Core variables
Structure
How much healthy tooth or bone remains. And what structural failure pattern is forming.
Force
How bite pressure distributes across teeth and restorations over time.
Timing
Whether a condition is stable, progressing, or structurally compromised.
Long-term stability
What happens over 5–10 years under continued load and maintenance reality.
Dental treatment is often irreversible. SDF reduces irreversible mistakes by modeling long-term outcome patterns before intervention.
Framework logic domains
SDF operates across seven structural domains. These pages explain the logic that powers the model.
Replacement decisions
Tooth replacement changes load distribution and maintenance reality.
- Implants vs bridges vs leaving space
- Bone response and structural tradeoffs
- Long-term stability planning
Restoration thresholds
When small damage becomes structural failure. And when monitoring is safer.
- Filling vs crown thresholds
- Crown vs root canal decision points
- Monitoring vs intervention timing
Force & stability
Force drives failure patterns. Stability changes outcomes.
- Grinding and overload patterns
- Bite instability and collapse risk
- Force-aware planning before treatment
Aging patterns
How teeth, bone, and prior work change over decades.
- Options narrow as structure is lost
- Force tolerance shifts over time
- Timing windows close quietly
Failure patterns
How fillings, crowns, root canals, bridges, and implants fail over time.
- Predictable failure modes by category
- Force and structure as root causes
- Why redo work cascades
Tissue & bone stability
When soft tissue and bone define what stays predictable.
- Recession causes and stability limits
- Thin bone and envelope constraints
- Graft timing and long-term outcomes
System-wide planning
When one-tooth dentistry hides system collapse.
- Staged planning and sequencing
- Full-mouth risk mapping
- Bite collapse trajectories over time
