Watch first

What MARPE is, in Mark's own words.

The problem this course solves

In adults, a narrow maxilla usually means a compromise.

Dentoalveolar expansion, camouflage, or a referral to surgery.

Without skeletal expansion, orthodontists fall back on alternative methods for transverse discrepancies, often limited by the patient's age or a lack of supporting structures. The treatment plan bends around what the method can do.

MARPE transfers the expansion force to bone through mini-implants. Whether it works for a given patient depends on case selection on CBCT, appliance design and the activation protocol. That is what this course teaches, step by step, in the order you use it in the clinic.

Module 3 · CBCT analysis Illustration: coronal CBCT slice of the maxilla with the midpalatal suture and a skeletal width measurement

Illustration. Midpalatal suture and skeletal width on a coronal slice.

What you'll be able to do

From CBCT to retention, the whole protocol.

The modules follow the order of a real MARPE case: diagnosis, device, laboratory, installation, activation, retention.

  1. 01 Select patients: assess the midpalatal and zygomaticomaxillary sutures and skeletal width on CBCT.
  2. 02 Choose the MARPE device and plan TAD placement with a surgical navigation template.
  3. 03 Work with your dental technician: appliance design, expansion screw, digital or analog workflow.
  4. 04 Install, activate and retain, and prevent the typical installation and activation errors.
