Rapid maxillary expansion (abbreviated RME) is done by a fixed appliance designed to widen the upper jaw’s bony base. It was first introduced by Angell in 1877. However, he was not taken seriously as the mere possibility of expansion of the bony palate was disputed and the procedure was initially forgotten about for decades. It […]

After having completed the orthodontic treatment, the anterior teeth have a lifelong tendency to relapse into the old tooth position. To prevent relapse, permanent stabilization of the anterior teeth in particular is required after active treatment. Fixed and removable retainers Retainers are all braces that are used to stabilize the position of teeth after orthodontic […]
Retention
All measures to stabilize an orthodontic treatment result after the end of active treatment are called retention in orthodontics. Retention is a necessary part of orthodontic treatment because all tooth movements tend to return towards their initial state after the end of treatment. This is especially true for the anterior teeth, whose permanent straightening naturally […]

Root cement

Root resorption refers to apical granulomas on the roots of the teeth which can lead to the appearance of small dimples or even to the disappearance of whole root tips. This can of course happen as part of the normal bite, even in the absence of any orthodontic treatment, but it does tend to be […]
