Adhesive Class VI Resin Composite Restorations of Worn Mandibular Incisal Edges: A Two-year Case Report
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.SUMMARY
Lower anterior teeth exhibiting ‘cupped’ incisal edges, non-carious cervical lesions.
Relationship of anterior teeth in initial protrusive movement.
Isolation with rubber dam.
Appearance of incisal tooth surface following air abrasion, showing removal of shiny dentin layer. (Large defect on a different patient pictured for clarity.)
Restorations of microhybrid resin composite immediately after placement.
Restorations after two years, showing continued attrition of resin composite.
Restorations after two years, facial view.
