Maryland Orthodontic Assistants

Trapezio is proud to be an approved training program in Maryland for those individuals seeking to become a Dental Assistant Qualified in Orthodontic Duties.

In order to meet the requirements in Maryland and be eligible to sit for the MDO exam, orthodontic team members can complete our Academy of Orthodontic Assisting Level 1 and 2 programs*.  Upon successful completion of both levels, students will apply to sit for the exam (offered by DANB) and then apply to the Maryland Board.  Visit the links below for additional information and applications.

Current Certified Orthodontic Assistants (COAs) can apply directly to the Maryland Board for state registration.
