Mixed dentition orthodontic treatment

Learn about what is normal, what can go wrong and how to fix it
The one and a half day online course will aid general dentists who want to add mixed dentition orthodontic treatment to their repertoire without necessarily resorting to full fixed appliance treatment.

Course overview

In this interactive online course you will be guided by Dr Morris Rapaport who will cover normal occlusal development and look at the common departures from normal and look in detail at ways to treat abnormality that are appropriate to general dental practice. Hygienists and therapists interested in recognising developing occlusal abnormalities will also benefit from attending.

There will be a “tell us all just one thing you learned in this course” session at the end of day one and a self-marking test at the conclusion of day two. This enables revision of the content, reinforces it, exposes any gaps in your knowledge and enables self-reflection on how much each participant has absorbed and understood.

Please be advised that we have updated this course to be delivered fully online via Zoom.


  • From 0 to 12 years of age the normal of each developmental stage will be contrasted with the abnormal, with supporting literature cited for various treatments if treatment is indicated
  • Diagnosing space loss and space regaining, space maintaining treatments
  • Class II Functional Appliance Treatment abridged - there is a separate full day CE course (because it needs at least a full day)
  • Anterior Crossbites treatment in the deciduous dentition with differential diagnosis of Class III
  • Anterior Crossbites treatment in the mixed dentition with differential diagnosis of Class III
  • Class III mixed dentition treatments
  • Posterior Crossbite treatment with and without functional shifts
  • Orthopaedic expansion of the palate and diagnosing adenoid involvement
  • First molars impacting under Es and disimpacting methods

Learning objectives

  • How to recognise abnormality in early and mixed dentition
  • How to treat the common early and mixed dentition problems that arise

Practical advice and demonstrations

  • Fitting a band to a molar or bicuspid, using greenstick and then taking an impression before sending it to the dental laboratory
  • Designing orthodontic appliances: together we will complete a laboratory instruction slip for each of the appliances shown in the course slides
  • Using segments of fixed appliances for minor corrections and space regaining. As a demonstration we will bond some brackets onto teeth, tie or module the segment of archwire into the brackets after slipping coil spring over the wire segment. This will show not just how it’s done, but also, what instruments and materials can be used and what inventory might be needed
  • Recording a protrusive bite for a removable functional appliance
  • What you can and should do, maybe do, shouldn't do
  • When to wait and watch
  • What is not cost effective for the patient

Course presenter

Dr Morris Rapaport BDS, MDSc

Morris Rapaport first graduated in 1976 and then obtained an MDSc in Orthodontics from the University of Sydney in 1980. He is in specialist orthodontic practice in Sydney, is an Senior Clinical Lecturer at The University of Sydney and an Adjunct part-time Senior Clinical Lecturer at Charles Sturt University, a Clinical Lecturer for Invisalign in Asia-Pacific and is an Invisalign Platinum Elite Provider. He has been involved in undergraduate and postgraduate teaching for decades and has lectured nationally and internationally.

Morris has had a long interest in functional appliances and in the early 1990s developed a course in the clinical use and theoretical underpinning of functional appliances, which he delivers annually to the Sydney University postgraduate students. After receiving an award for “outstanding presentation and treatment” of a case he began treating in 1991 with the then-new Clark Twin Blocks, he published a paper in the Australian Orthodontic Journal (March 1998) demonstrating the application of the Bass Aesthetic Analysis in functional appliance diagnosis.

Morris is well known for his ability to simplify complex issues and presents them using liberal doses of humour to make lectures not only highly accessible, but enjoyable and memorable.
