Abstract

This study evaluated the clinical performance of a polymer-infiltrated ceramic-network (PICN) material for up to 3 years. Patients (N=286) received 581 indirect restorations as crowns (417), overlays (131), and inlays/veneers (33) fabricated using the PICN (VITA Enamic) by CAD/CAM procedures using intraoral scanning (Cerec Omnicam) and milling systems (Cerec MC XL). The restorations were evaluated annually and in case of complications. Data were analyzed using Kaplan-Meier estimate. Complications were classified as biological or technical failures. Until final recall (mean observation period: 18.3 months) with a dropout rate of 4.8%, 3 biological and 10 technical complications were observed. The overall success rate of the placed restorations was 97.7%. Biological complications included pulpitis and pulp necrosis. Technical complications were debonding (n=7) and fracture (n=3). PICN materials can be used as an alternative to lithium-disilicate or zirconium dioxide for single tooth reconstructions, providing that early failures included debonding and fractures.

观察期长达三年的聚合物渗入陶瓷网单牙修复体的存活率和并发症发生率。

这项研究评估了聚合物浸润陶瓷网（PICN）材料长达 3 年的临床表现。通过口内扫描（Cerec Omnicam）和铣削系统（Cerec MC XL）的 CAD/CAM 程序，患者（N=286）接受了 581 次间接修复，包括牙冠（417 次）、覆盖层（131 次）和嵌体/veneers（33 次），均使用 PICN（VITA Enamic）材料制作。每年对修复体进行一次评估，并在出现并发症时进行评估。数据采用 Kaplan-Meier 估计法进行分析。并发症分为生物失败和技术失败。截至最后的回访（平均观察期：18.3 个月），共观察到 3 例生物并发症和 10 例技术并发症，辍学率为 4.8%。修复体的总体成功率为 97.7%。生物并发症包括牙髓炎和牙髓坏死。技术并发症包括脱钩（7 例）和断裂（3 例）。PICN材料可替代二硅酸锂或二氧化锆用于单牙重建，前提是早期失败包括脱粘和折裂。
