INTRODUCTION
The extensively damaged teeth can be treated with the inlay and onlay. The ceramic inlays and onlays can be prescribed for the esthetic needs of the patient. Hence in our study, we aim to evaluate clinically the outcomes of the ceramic inlays and onlays for the posterior teeth.
MATERIALS AND METHODS
We piloted a retrospective analytical study from the departmental records. We included 70 patients who had a total of 160 ceramic inlays and onlays prepared between the years 2010-2020. The survival and the failure rates were noted and compared using the "Kruskal-Wallis H statistics and the Chi-square tests" deliberating < 0.05 as significant.
RESULTS
The mean survival was 6.1 ± 1.8 years. The success rate was 92.21% and the failure was 7.6%. Significant variation was seen with the survival rate between the vital and nonvital teeth and between the molars and premolars.
CONCLUSIONS
The ceramic inlays and onlays were performed successfully in the posterior teeth with a high survival rate and very low failure.
引言
大面积损坏的牙齿可用嵌体和高嵌体进行治疗。陶瓷嵌体和高嵌体可根据患者的美学需求进行定制。因此，在我们的研究中，我们旨在临床评估陶瓷嵌体和高嵌体用于后牙的效果。
材料与方法
我们从科室记录中开展了一项回顾性分析研究。我们纳入了70例患者，他们在2010年至2020年间共制作了160个陶瓷嵌体和高嵌体。记录并使用“Kruskal-Wallis H统计量和卡方检验”比较了生存率和失败率，将P<0.05视为具有显著性。
结果
平均生存时间为6.1±1.8年。成功率为92.21%，失败率为7.6%。在活髓牙与无髓牙之间以及磨牙与前磨牙之间，生存率存在显著差异。
结论
陶瓷嵌体和高嵌体在后牙的应用取得了成功，生存率高且失败率极低。
