Dr. Isaac SunFounder of KYT Dental Services
Dr. Isaac Sun is the founder of KYT Dental Services and the creator of the Structural Decision Framework (SDF). He’s known for a calm, long-term approach — dentistry designed to still make sense years later.
Most dentistry is judged by how it looks when it’s done. Dr. Sun focuses on what matters more: what still works after time, force, and real life have a turn.
What shaped his perspective most wasn’t a single case — it was seeing the end of the story. Late-stage patients don’t show you what was “good dentistry” that day. They show you what held up — and what quietly collapsed.
That’s why SDF exists: to make the long-term consequences visible earlier — so younger patients don’t lose options before they realize what’s happening.
Dr. Sun regularly treats late-stage patients. At that point, the mouth reveals the real outcome of decisions made years earlier — what held up, what quietly failed, and what choices removed the best options.
He noticed a pattern: many “surprises” aren’t bad luck. They’re the compounded result of force patterns, structural fatigue, timing decisions, and shortcuts that looked harmless in the moment.
The Structural Decision Framework (SDF) was built to bring that long-term truth forward — so younger patients can make decisions that protect their future options, not just today’s symptom.
