OBJECTIVE
To clinically evaluate and compare the performance of posterior pediatric zirconia crowns with stainless steel crowns.
MATERIALS AND METHODS
Twenty nine children [3-9 years] were selected and given 70 preformed crowns [35: preformed zirconia crowns, Kinderkrown; 35: stainless steel crowns, KIDZ CROWN]. Crowns were evaluated for retention, marginal integrity, opposing tooth wear, plaque accumulation, gingival inflammation, and proximal contact at 3, 6, 9, and 12th month.
RESULTS
At the end of follow-up period overall success rate with zirconia crown was 93.5% and that of stainless steel crown was 96.7%. Statistical analysis showed no difference between the groups.
CONCLUSION
Posterior preformed zirconia and stainless steel crowns showed good clinical performance. Preformed zirconia crowns can be an option for posterior full coronal restoration when esthetics is of prime concern for the parent and child.

目的
对儿童后牙氧化锆全冠和不锈钢全冠的性能进行临床评估和比较。
材料与方法
选取29名3至9岁儿童，为其提供70个预成冠（35个预成氧化锆全冠，Kinderkrown；35个不锈钢全冠，KIDZ CROWN）。在第3、6、9和12个月时，对全冠的固位、边缘完整性、对颌牙磨损、菌斑积聚、牙龈炎症和邻面接触情况进行评估。
结果
随访期末，氧化锆全冠的总体成功率为93.5%，不锈钢全冠为96.7%。统计分析显示两组之间无差异。
结论
后牙预成氧化锆全冠和不锈钢全冠均表现出良好的临床性能。当美观是家长和孩子首要关注的问题时，预成氧化锆全冠可作为后牙全冠修复的一种选择。
