Extractions in orthodontics: aligners, braces, microimplants, transpalatal arches
Course overview
To extract or not to extract, that is the question. And we have prepared a comprehensive answer!
Analysis from A to Z of extraction methods in orthodontic treatment, selection thinking strategies and clinical cases. With the new course you will learn:
biomechanics of treatment with extraction
protocols for serial tooth extraction and germectomy in mixed dentition
protocol for the treatment of Class 2 with extraction
aligner therapy with extraction
features of the use of transpalatal arches (TPA) and their modifications
lingual orthodontic protocols for space closure.
We invite you to study and close this issue, based on the most modern research and protocols!
