Abstract
Early Childhood Caries (ECC) is a public health problem of global proportions, which involves the early carious involvement
of the primary maxillary incisors followed by the maxillary and mandibular first primary molars and the mandibular cuspids. For
many years, the preformed paediatric metal crown (stainless steel crown (SSC)) was considered as a gold standard. However, to
over disadvantages of SSC preformed pediatric zirconia crowns are introduced recently. Some drawbacks which limit the use of
zirconia crowns are that it requires significantly more time to prepare the tooth for fitting the crown and its inability to manipulate
its margin and adaptability. To overcome disadvantages of Preformed Zirconia Crowns Computer-aided design and manufacturing
(CAD/CAM) technology came to rescue and made enormous improvements since its introduction. In this article, through a clinical
case, we present the protocol and implementation of a paediatric zirconia crown prepared with digital workflow and its followup.
the restoration performance is excellent exhibiting no chipping, no discoloration, and displays an excellent marginal fit and no
plaque deposition.
