The aim of this study was to assess the clinical performance of computer-aided design and computer-aided manufacturing resin nanoceramic posterior restorations fabricated by CEREC Omnicam system.
Fifty-seven Lava Ultimate posterior restorations were placed in 44 patients by one operator. Restorations were cemented using a resin cement system (Duo-Link). The clinical performance of the restorations was evaluated with USPHS guidelines in a mean time of 45-month. Data were statistically analyzed using Kaplan-Meier and Log Rank (Mantel-Cox) tests (SPSS 22.0, α = 0.05).
Thirty-eight restorations in 26 patients were evaluated at recall examinations by two evaluators other than the clinician who had placed the restorations who were blinded to groups. The survival rates of Lava Ultimate were 86.8%. A total of 5 (13.2%) failures were found. After a mean time of 45-month survival rate of vital and non-vital teeth were 90 and 83.3% respectively. The failures were not significantly influenced by gender, tooth arch, restoration size, the treated region and vitality.
Chair-side posterior resin nanoceramic restorations were clinically successful restorations with a survival rate of 86.8% after a mean time of 45-month.
Chair-side CAD/CAM resin nanoceramic restorations can be a successful choice for vital and non-vital teeth with acceptable survival rates.
本研究旨在评估 CEREC Omnicam 系统制作的计算机辅助设计和计算机辅助制造树脂纳米陶瓷后修复体的临床性能。
由一名操作员将 57 个 Lava Ultimate 后修复体放置在 44 名患者中。使用树脂粘接系统（Duo-Link）粘接修复体。在平均 45 个月的时间内，根据 USPHS 指南评估修复体的临床性能。使用 Kaplan-Meier 和 Log Rank（Mantel-Cox）检验（SPSS 22.0，α=0.05）对数据进行统计学分析。
在召回检查中，由两名评估员评估了 26 名患者中的 38 个修复体，这两名评估员除了放置修复体的临床医生外，均对分组情况不知情。Lava Ultimate 的存活率为 86.8%。共发现 5 例（13.2%）失败。经过平均 45 个月的随访，活髓牙和无髓牙的存活率分别为 90%和 83.3%。失败情况不受性别、牙弓、修复体大小、治疗区域和活力的显著影响。
椅旁后树脂纳米陶瓷修复体是一种临床成功的修复体，在平均 45 个月的随访后，存活率为 86.8%。
椅旁 CAD/CAM 树脂纳米陶瓷修复体可为活髓和无髓牙提供可接受的存活率，是一种成功的选择。
