应用龈壁提升术修复牙体缺损的研究进展

Research progress on deep margin elevation in tooth defect restorations

当牙体邻面缺损位于龈下时,龈壁提升术是目前临床上越来越流行的治疗手段。随着粘接技术的发展,保存牙科概念的盛行,因为其微创,所需治疗时间少、使后期修复更加便捷等特点越来越被临床医生所选择。但至今对龈壁提升术尚无明确的定义和规范统一的临床操作方法,亦无足够的体外实验及临床随机对照实验来验证龈壁提升术的科学性和可靠性。因此,本文从多方面评价龈壁提升术,对上述相关问题作一综述。

Deep margin elevation has become a popular technique for restoring tooth defects with a proximal cavity margin located beneath gingival tissues. With advances in materials technology and the prevalence of minimally invasive methods, less invasive, less time-consuming and less complicated restorations have become feasible. However, a clear definition or a standard operating method on deep margin elevation and sufficient in vitro studies or in vivo randomised controlled trials have yet to be performed to verify the scientificity and reliability of this technique. This article aims to retrospectively evaluate deep margin elevation.
