Clinical tips
The use of attachments on all premolars and molars is useful to control the maxillary expansion during buccal movement, which releases an extrusive force on those attachments. The result is the creation of a couple of forces generating a movement, thereby facilitating the buccolingual control of premolars and molars. In other words, a controlled buccal movement of their roots can be achieved. In addition, the extrusive force will improve the final intercuspation in the premolar and molar areas, reducing the bite-block effect described for aligner orthodontics.
This case shows how it is possible to perform the orthosurgical traction of an impacted lower premolar with aligners, buttons and elastics, without braces and wires. This was greatly appreciated by the patient and the parents. Comfortable and aesthetic solutions can be a fundamental requirement for teenagers.
Comparison of this case with patients prescribed aligner changes every 2 weeks
A regimen of aligner changes every 2 weeks could provide similar results but would extend the treatment time by up to twice the duration. Furthermore, the orthodontic traction of impacted teeth can be extremely variable in terms of required time. This is the main reason why, in cases where no complex movements are required to prepare the traction, weekly aligner changes are recommended, in order to avoid a long treatment duration and [...]
