Abstract：
Many authors have advocated retentive tooth preparations for resin composite restorations intended to halt progression of incisal edge attrition with worn concave dentin, probably due to frustration with adhesive restorations being lost from these defects. Unfortunately, this technique further removes the dentin these restorations are intended to preserve. The purpose of this article is to demonstrate a purely adhesive, less invasive technique for restoration of worn concave incisal edges, which includes air particle abrasion and increased etching time for the sclerotic dentin and unprepared enamel. Favorable two-year results for mandibular anterior teeth opposed by natural teeth are reported.
摘要：
许多作者主张使用树脂复合材料修复体的固位牙齿制剂，旨在阻止磨损的凹面牙本质的切缘磨损的进展，可能是由于这些缺陷失去了粘合剂修复体的挫败感。不幸的是,该技术进一步去除这些修复物旨在保存的牙本质。本文的目的是演示一种纯粘合剂，微创技术修复磨损的凹形切缘，其中包括空气颗粒磨损和硬化牙本质和未准备好的牙釉质的蚀刻时间增加。据报道，与天然牙齿相对的下颌前牙的两年效果良好。
