Basic ABC Orthodontics

Revisiting ABC orthodontics…

The unlocking principles still apply

Dr. Michel Champagne, BA, DMD, MAGD, IBO, CDE 

Orthodontic therapies are multiplying like little bunnies leaving the clinician with more and more choices. What is the best solution for the next case that comes your way:

  1. Slow or rapid maxillary expansion
  2. One or two phases
  3. Surgically assisted maxillary expansion
  4. Expansion supported by mini-screws
  5. Fixed orthodontics with brackets
  6. Orthodontics with clear aligners
  7. Hybrid approach (aligners et fixed)
  8. or any other approach.

You may have a problem choosing, not mentioning what might come out as a new approach…next month???. As a clinician, each new case confronts us with a choice influenced by the patient major complaints, our own observations, the anticipated cooperation, the age, the length of treatment, the retention and many other factors. In this tornado of choices, going back to the basic ABC principles that I could also call the TVAP (Transverse, Vertical, AnteroPosterior) may help us in our case planning. The logical order to look at a case is always the same no matter what technique you will be using (there will always be exceptions). We have to evaluate the case needs in unlocking first in the Transverse dimension, second in the Vertical dimension, finally in the Antero-Posterior dimension and then plan accordingly.

Evaluating the transverse needs is of prime importance for the growing patient because the maxillary transverse growth will end first. A non treated transverse anomaly has a major impact on the airway, the vertical and the AP. Even in the permanent dentition, the transverse should always be evaluated because the transverse will ease the treatment of other dimensions whatever the technique you use (fixed brackets, aligners or hybrid). Go back to the infoletter of March 9 2019 ”Is Unlocking…the Key to Success”.

In our present orthodontic world were techniques are multiplying at a fabulous rate, it is always good to keep a sound and logical approach to our treatments.
