Correction of dental Class III with posterior open bite by simple biomechanics using
an anterior C-tube miniplate.
- Korean J Orthod 2012;42(5):270-278
Q1. I would like to congratulate the authors for publishing the article, which shows
a precise, controlled and simple solution for a critical clinical situation. Accor
ding to Figure 5, correction of the posterior open bite occurred in just 4 months.
The figure also shows the left posterior occlusion reached a more desirable relationship
than the rights after 4 months. This posterior occlusal imbalance, perhaps due to
unequal bilateral arch force, seems to require some additional correction of right
mandibular posterior teeth during the finalization of the orthodontic therapy.
Q2. Another question. As the teeth positions improved, has there been any height changes
of brass wire in C-tube miniplate? Also, I can assume that the amount of force delivered
can be controlled by the thickness of the wire in the reverse curve. What is the average
force level advocated by the authors for this therapy?
