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.
