What MARPE is, in Mark's own words.
The problem this course solves
MARPE failure is 80% case selection.
Mid-palatal suture maturation stage on CBCT > chronological age. Always.
The standard MARPE failure pattern is not surgical. It is selecting the wrong patient: a closed mid-palatal suture, a fused circumzygomatic ridge, a parasagittal bone density profile that won't yield under expansion forces. Age tells you very little. CBCT tells you almost everything.
Module 1 walks through CBCT-based selection: how to stage suture maturation (Angelieri A–E), how to read CVM in parallel, and how to write a one-paragraph case-selection note that protects you when an expansion stalls.

What you'll do
After this course you can do, not just describe.
Four operator-level competencies. The course is structured backwards from these. Each module is judged by whether it gets you closer to the claim below.
- 01 Classify mid-palatal suture maturation (Angelieri A–E) on a CBCT axial slice in under 90 seconds.
- 02 Decide MARPE vs SARPE vs adjunct surgical assistance with a written, defensible note that survives second-opinion review.
- 03 Place mini-screws on a trajectory that clears the greater palatine artery and nasal floor, every time, regardless of palatal vault depth.
- 04 Document a post-expansion case in a format that referrers, insurers, and journals all accept without rework.

Lecturer
Mark Radzhabov, MARPE lecturer.
This course was assembled from cases Mark and his department treated. The lessons reference the failures as carefully as the successes.
Dr Mark Radzhabov is an orthodontist and head of an orthodontic department, with 12 years of clinical practice and 8 years of focused research on MARPE outcomes in adult and adolescent patients. He lectures at OrthodontExpert and treats a referral-base of complex transverse-deficiency cases.
The MARPE course in front of you is the same teaching curriculum he runs internally with his residents. It exists because he was repeatedly asked by colleagues to put it on video; the trial cohort of 110+ orthodontists is what convinced him to release it publicly.

FAQ
Things people ask before they buy.
Six straightforward answers. If you have a different question, write to mark@ortodontmark.com — Mark replies personally to pre-purchase questions inside 24 hours.
How long does the course take to complete?
Total runtime is around 14 hours of video plus the resource library. Most working orthodontists complete it in 4–6 weeks at 2–3 hours per week. You have lifetime access, so there is no deadline.
What is included in the $1899 tier that the others don't have?
One thing: dedicated weekly time with Mark for three months, including a recurring slot on his calendar and unlimited case submissions during that window. If you don't have an active or upcoming case to work on, the $899 tier is the better fit.
Do I need prior MARPE experience?
No. The course assumes a licensed orthodontist who is comfortable reading a CBCT but has not necessarily placed mini-screws. About 30% of past cohort participants had zero MARPE cases on their record at enrolment.
What is the refund policy?
30 days from purchase, no questions asked. Refund is processed through whop.com directly. Lifetime access cancels with the refund (you keep the resource downloads taken during the window only if you don't request the refund).
What format is the content in? Can I watch on mobile?
Video is hosted on the course platform (Whop). 1080p with subtitles in English, Russian, Portuguese, and Spanish. Mobile, tablet, and desktop all supported. Downloadable PDFs for the resource library.
Is the certificate recognised by my board?
The certificate is a course-completion certificate, not a board credential. It is acceptable as proof of CPD in jurisdictions where self-directed online study qualifies (most of Europe, Latin America, parts of Asia). Check your local CPD rules. If your board requires a specific provider, contact Mark before purchasing.
