Unfortunately, a smooth transition is often disrupted by the premature loss of teeth. Tooth decay, trauma from a fall, or some other accidental injury are just some of the common causes of early tooth loss. When tooth loss occurs, pediatric space management is the key to preventing a serious malocclusion in the permanent dentition. In the posterior quadrants, the early loss of primary teeth often results in a reduction of arch length. This change can directly affect the normal eruption of the adult teeth. If space loss has not already occurred, rapid intervention with a space-maintaining appliance is of utmost importance. In the anterior region, space maintenance is important to maintain normal speech, function, and esthetics.
