title: Space maintenance in the primary and mixed dentition.
abstract: The maintenance of arch length in the primary, mixed and early permanent dentition is important for the normal development of the occlusion. Premature loss of primary teeth can result in the loss of arch length leading to malocclusion. Space maintenance can often prevent space loss and either prevent the development of a later malocclusion or reduce its severity. The pattern of space loss depends on many factors including age, stage of development, which teeth have been lost, the presence of crowding or spacing, and occlusal relationships. Careful consideration of many factors is required when deciding whether space maintenance is indicated. Radiographs and space analysis can be helpful. Space maintainers can be fixed or removable. Band and loop space maintainers have fewer problems than other types. Frequent follow-ups to check for any problems following space maintainer insertion is recommended.
