Definition : Stainless Steel Crowns are for protection of restoration of caries infected deciduous tooth.
Function : Stainless Steel Crowns protect the restoration of caries infected deciduous teeth while allowing normal mastication and maintaining adequate space for the eruption of permanent teeth.
Deciduous Teeth : The 20 deciduous teeth usually begin to erupt at the age of 6 months and continue to about the age of 30 months. Deciduous teeth are naturally replaced by permanent teeth between the ages 7 to 12 years.
Permanent Teeth : There are 28 permanent teeth. The first molar (back teeth) starts to appear between the ages 7 and 7 years and continue erupting until the ages of 10 to 12 years.
Applications : Dental Caries (tooth decay) is the most common disease known to humans and often destroys deciduous teeth if they are not cleaned and taken proper care daily.
In cases of decay, the teeth can be restored in many ways. However, damaged teeth when repaired often fall under the heavy forces of mastication (chewing).
For that reason, Stainless steel (KIDS Crowns) are used in order to restore the teeth and to enable them to withstand the forces of chewing without breaking.
Deciduous teeth which are severely compromised by caries (decay) are frequently treated and restored with stainless steel crowns (KIDS Crowns).
Sometimes deciduous teeth are so badly decayed that they require root treatment. Such treated teeth are considerably weakened and can be fitted with Stainless Steel Crowns (KIDS Crowns) to preserve them until they are replaced by permanent teeth. Deciduous teeth fitted with Primary Stainless Steel Crowns exfoliate (come out) naturally with the appearance of the underlying permanent tooth. Primary Stainless Steel Crowns stay attached to the treated tooth on exfoliation.
