The aim of this case report was to present a minimally invasive and esthetic treatment approach for the replacement of missing teeth removable partial dentures retained by zirconia ceramic resin-bonded attachments.
The resin-bonded attachments were digitally designed and milled using CAD/CAM technology from monolithic 3Y-TZP zirconia ceramic. The resin-bonded attachments had an optimized attachment design approved for zirconia ceramic. The preparation was based on general preparation guidelines for resin-bonded attachments and resin-bonded fixed dental prostheses (RBFDPs). After placement of rubber dam, the resin-bonded attachments were bonded with a phosphate monomer-containing luting resin.
The presented resin-bonded attachment-retained removable partial denture was successful over 30 months of clinical observation without any complications. The patient was satisfied with the minimally invasive treatment procedure.
Zirconia ceramic resin-bonded attachments fabricated with a special attachment design are an esthetic and minimally invasive treatment approach. However, clinical data on the long-term outcome of zirconia resin-bonded attachments are still needed. (Quintessence Int 2023;54:220-226; doi: 10.3290/j.qi.b3819523).
本病例报告旨在介绍一种采用氧化锆陶瓷树脂粘结附件固位的可摘局部义齿修复缺失牙的微创且美观的治疗方法。
采用CAD/CAM技术，从整块3Y-TZP氧化锆陶瓷数字化设计并铣削树脂粘结附件。树脂粘结附件具有经批准用于氧化锆陶瓷的优化附件设计。预备工作基于树脂粘结附件和树脂粘结固定义齿（RBFDPs）的一般预备指南。放置橡皮障后，用含磷酸盐单体的粘结树脂粘结树脂粘结附件。
经过30个月的临床观察，所呈现的树脂粘结附件固位的可摘局部义齿成功，无任何并发症。患者对微创治疗过程满意。
采用特殊附件设计制作的氧化锆陶瓷树脂粘结附件是一种美观且微创的治疗方法。然而，仍需要关于氧化锆树脂粘结附件长期疗效的临床数据。（《精华国际》2023年；54:220 - 226；doi: 10.3290/j.qi.b3819523）
