Incisal angle adhesive resins: a 5-year clinical survey of two materials.
Two hundred and seventy-eight restoration examinations were made of Concise and Nuva-fil resins used to restore fractured incisors, over periods of up to 5 years. Following the placement of wide bevels along the fracture margins, retention was achieved by using acid-etching with bonding resins and by pins in some instances. Although the short-term results were usually reasonable, provided that the materials had been placed and finished correctly, longer-term findings revealed problems of resin darkening and corrosion staining of dentine from exposed pins. The Nuva-Fil restorations were generally superior to the Concise restorations.
