The authors describe a study in which they placed 126 Class V composite resin restorations without mechanical retention, divided into three groups of 42, in 23 patients. They followed the performance of the restorations over a three-year period. For all three groups, restorations were placed using All-Bond 2 dental adhesive and Z100 composite resin; A.R.T. Bond and Brilliant Dentin composite; and Prisma Universal Bond 3 and Variglass VLC polyacid-modified composite resin. The authors evaluated retention as well as color stability, wear resistance, sensitivity, sulcular depth, loss of attachment, bleeding on probing and crevicular fluid flow. Based on their results, the authors propose that restoration of Class V lesions without using mechanical retention could be expected to succeed in seven of 10 restorations over a three-year period using these restorative systems.
作者描述了一项研究，他们在23名患者中放置了126个无机械固位的V类复合树脂修复体，分为三组，每组42个。他们对修复体的性能进行了为期三年的跟踪。对于所有三组，修复体均使用全粘结2型牙科粘合剂和Z100复合树脂、A.R.T.粘结剂和亮牙本质复合树脂、以及普瑞玛通用粘结剂3型和Variglass VLC聚酸改性复合树脂进行放置。作者评估了固位情况以及颜色稳定性、耐磨性、敏感性、龈沟深度、附着丧失、探诊出血和龈沟液流动情况。基于他们的结果，作者提出，使用这些修复系统，在三年时间里，10个V类洞病变修复体中预计有7个在不使用机械固位的情况下能够成功。
