Prevention of the mesialization towards the support zones, support of the masticatory function and reduction of the speech impediment
Description:
Proper function is only guaranteed if special attention is paid to the good adjustment of the space maintainer
The gingival margin is slightly erased because of the missing undercut areas on the deciduous teeth. This way the children’s denture gets good support.
As the deciduous crowns are normally quite small, the retention elements are bent out of thinner wire than usual. The Adams clasp is recommended for this appliance. It should be bent with due care and should adapt exactly.
The preformed teeth are grinded in shape if deciduous preformed teeth are not available. Eventually they are set onto the cast with small spaces.
On the anterior and posterior teeth a small bit of gingival tissue is modeled. This enhances the support and optimizes the esthetics as the upper lip does not seem so retruded.
The prepared teeth are fixed with a barrier of silicon or plaster in order to eliminate the wax and replace it with acrylic. A normal expansion screw can be incorporated to activate the plate according to the growth of the patients jaw.
The base of the plate of the space maintainer can be made with the normal spray-on technique.
