 The study found no significant difference in shear bond strength between monocrystalline and polycrystalline ceramic brackets when bonded to unruffened or roughened resin composite discs, but a higher frequency of resin composite fracture was observed with the polycrystalline brackets. It is concluded that debonding any type of ceramic bracket from a resin composite surface may cause damage to the resin composite itself.
