A prefabricated zirconia crown was considered for the tooth because the parents disapproved the color of SSC. The computer-aided design/computer-aided manufacturing (CAD/CAM) technology was used to fabricate a zirconia crown with porcelain veneering since the size of prefabricated crowns did not match the size of the respective tooth.</span></span></span></span><br> <span style="font-size:13pt"><span new="" roman="" style="font-family:" times=""><b><span style="font-size:9.0pt"><span style="font-family:" verdana=""><span style="color:#2e74b5">Conclusion:</span></span></span></b> <span style="font-size:9.0pt"><span style="font-family:" verdana="">At the 1-year follow-up, the crown fabricated with this technique showed optimal esthetics, function, and durability. Although these crowns have shortcomings such as the risk of porcelain chipping, and require greater tooth preparation than SSCs, they can serve as a suitable alternative for reconstruction of severely damaged primary teeth when esthetics is an important parameter to consider. </span></span></span></span></td> </tr> </tbody> </table> </div> CAD-CAM,Deciduous teeth,zirconia-based ceramic 168 174 http://jrdms.dentaliau.ac.ir/browse.php?a_code=A-10-297-1&slc_lang=en&sid=1 P Bakhtiary pegahbakhtiary85@gmail.com 100319475328460010432 0000000206226284 No Department of Pediatric Dentistry, Faculty of Dentistry, Tehran Medical Sciences, Islamic Azad University, Tehran, Iran P Aref parissa234@yahoo.com 100319475328460010433 0000000347813220 Yes Department of Pediatric Dentistry, Faculty of Dentistry, Tehran Medical Sciences, Islamic Azad University, Tehran, Iran
