Bond Strength of Metal and Ceramic Brackets on Resin Nanoceramic Material With Different Surface Treatments.

HFA and Nd: Yag laser are effective surface conditioning methods for resin nanoceramics. OPA combined with silane application caused optimum SBS and can be used as an alternative to HFA. Surface texture changes should be considered to determine surface damage while deciding the optimum surface conditioning method for ceramics other than SBS.
