Space Maintainer

 

 

Space maintainers are appliances which are frequently used in the preventive and interceptive stages of orthodontic supervision. As the name implies, these orthodontic appliances are aimed at preserving or maintaining the space already available for the eruption of the teeth while avoiding loosing space by preventing tooth migration. 

They “hold” in place the permanent teeth already erupted while other teeth complete their eruption. Space maintainers are usually utilized when there is a lack of space for the eruption of the permanent teeth and when teeth have an abnormal eruption pattern (which is visible on a panoramic radiograph).
