title: An improved technique for the retention of polycarbonate crowns.
abstract: The following conclusions may be drawn from this study: Composite resins do not bond to polycarbonate crowns. A technique for priming the internal surfaces of polycarbonate crowns is indicated, in order to create such a bond. Priming the polycarbonate crown with methyl methacrylate monomer alone produces a bond with composite resins. Priming the polycarbonate crown with a syrup of methyl methacrylate monomer and (poly) methyl methacrylate powder appears to produce a stronger bond with composite resins than the monomer alone.
