INBDE® prep — for every candidate
Case-first prep for U.S. dental students and internationally trained dentists alike: Patient Box practice, Foundation Knowledge re-taught from the start, and schedules sized for a real 3–6 month runway.

CODA-accredited first-attempt failure rate
50.5%
non-accredited retake failure rate
2025 figures from JCNDE's 2025 INBDE Technical Report, Table 16.1. “Non-accredited” is the report's label, not a nationality label. See the full pass-rate data.
Whether you're a U.S. dental student years past your early coursework or an internationally trained dentist bridging a knowledge gap, Dentovio's modules re-teach Foundation Knowledge under U.S. clinical framing instead of assuming you saw the material last semester.
Two hundred of the exam's 500 items are case-based, and Day 2 is nothing but Patient Box testlets. Practicing standalone flashcards does not build the chart-reading endurance the second day demands — so case practice is the core here, not an add-on.
One payment, no subscription clock. Your account keeps full INBDE access — including every new module as it clears review — until you pass the exam.
What's inside
The INBDE blueprint crosses 56 Clinical Content areas with 10 Foundation Knowledge areas. Dentovio's prep follows that structure — but paces it for candidates who are balancing work, are years past their foundational coursework, or are studying in a second language.
