Article history: Objectives: The aim of this study was to systematically review the available literature about
Received 10 March 2017 in vitro orthodontic bond strength tests regarding bonding brackets to acrylic teeth.
Accepted 13 July 2017 Methods: A comprehensive electronic database search with no date or language limits was
Available online 20 July 2017 conducted. Relevant studies were selected based on predefined criteria: in vitro investi-
gation on the shear/tensile bond strength of brackets evaluated and expressed in meg-
Keywords: apascals and/or considering the adhesive remnant index; and studies with a clear expla-
Acrylic resin nation of the bonding technique/protocol, bonding materials and type of surface acrylic
Adhesion material used.
Crowns Results: 2044 published articles were presented by the four databases. Of the studies
Dental bonding collected from all the databases, 28 based on their title and 14 based on their abstract,
Orthodontic brackets only 10 studies fulfilled the selection criteria after being examined twice by the two
Provisional material reviewers.
Conclusion: The type of surface noticeably influenced the adhesion, and surface treatments
should be performed to improve bond strength. (Rev Port Estomatol Med Dent Cir Maxilofac.
