Need of Spacemaintainer in Cases of Premature Primary Teeth Extraction

The premature loss of primary teeth is commonly associated with tooth decay and its complications, as well as with traumas. The aim of the this study is to find the need of space maintainers in order to save enough space for the future permanent teeth. We examined 90 children with premature primary teeth loss in both lower and upper jaw, divided into tree groups according to the severity of the orthodontic deformation. The statistical analysis were made using T-test, ANOVA and P- value. The use of space maintainers must be considered according to the time of the loss more than according to the tooth position in the jaws. The time as a factor of space loss is more significant than the lack or the presence of malocclusions. It means that no matter the jaw of the premature extraction the space maintainer should be used less than 2 month after tooth extraction. This will maintain the correct occlusal relationships
