Space maintenance is pretty straightforward. But what can be done in case it has been many years since extraction of milk teeth and space “loss” has already occurred?
That is when we “regain the space”. Why? Because we do not want the permanent teeth to erupt crookedly!
“If braces are anyway needed, why should we go through all this earlier? Can’t we correct it in one go?”..This is another question normally asked by parents. You have to understand, the main aim is to reduce the severity and duration of orthodontic treatment later. Also, we are trying to bypass crowding and avoid extraction of permanent teeth while fixing braces, which may otherwise be required.
The designs are similar to space maintainers, except a spring or screw may be inserted to open up space
How much time should these be worn? Depends on amount of space needed to “regain”. Your dentist will generally start fixed treatment with braces soon after this step.
