Pediatric space management is the key to preventing a serious malocclusion in the permanent dentition . The early loss of primary teeth often results in a reduction of arch length .This change can directly effect the normal eruption of the adult teeth . If the permanent teeth are not going to erupt within six months of the loss , a primary tooth appliance therapy is indicated.
Premature loss of anterior teeth in the young child can be due to tooth decay, trauma from a fall , or some other accidental injury . Space maintenance is important to maintain normal speech , function , and esthetics.
