title: Silane based concepts on bonding resin composite to metals.
abstract: BACKGROUND
  The longevity of silane promoted adhesion of surface conditioned metallic materials is of concern in dentistry and poses both a functional and esthetic dilemma for the patient and dental professionals. Several methods for surface conditioning exist, but some are employed more frequently in clinical practice.
  
  
  OBJECTIVE
  This overview aims to characterize and discuss the most commonly used surface conditioning methods based on silanization. The primary chemical features in silane treatment will also be presented.
  The literature regarding silane utilization was systematically selected and 68 cited references published during 1967-2005 were reviewed. Technical descriptions of different silica-coating (silicatization) methods are presented and some comparative clinical and in vitro experiences are reported. Some other surface condition methods applied in dental laboratories were also selected for presentation.
  
  
  CONCLUSIONS
  It is concluded in this overview tribochemical silica-coating followed by a mandatory silane coupling agent application is a clinically proved, relevant adhesion promotion method to enhance the bonding of resin composites to metallic dental materials.
