Class V restorations are a very common occurrence in clinics. Some reasons include an increase in non-carious cervical lesions (NCCL), root caries and the elderly population. Unfortunately, Class V restorations also represent one of the less durable types of restorations and have a high index of loss of retention, marginal excess and secondary caries. Some causes for these problems include difficulties in isolation, insertion, contouring, finishing and polishing procedures. This technique demonstrates an alternative isolation and insertion method using photocured gingival barrier in association with a flowable resin and hybrid resin composite to recreate the gingival wall with minimum or no excess.
V 类修复体在临床上非常常见。一些原因包括非龋性颈缘缺损(NCCL)、根面龋和老年人口的增加。不幸的是,V 类修复体也是保留率较低的修复体之一,其固位丧失、边缘多余和继发龋的发生率较高。导致这些问题的一些原因包括隔离、插入、塑形、修整和抛光过程中的困难。本技术使用光固化牙龈屏障结合可流动树脂和混合树脂复合材料,展示了一种替代的隔离和插入方法,以最小或无多余的方式重建牙龈壁。
