Microtensile bond strength of resin-based composites to Ti–6Al–4V

Effect of Air Abrasion and Different Silicoating Techniques on the Bond Strength of Particulate Filler Composite to Titanium

“…However, one of the problems associated with titanium metal-composite restorations is insufficient ability to bond resin to titanium metal castings. The deficient bonding of indirect composites to the metallic alloys could promote the formation of marginal gaps and causing weak bond strength [2,3,6,8,9]. Like other metal alloys, use of titanium alloy for fixed partial denture requires a strong and stable bond between metal and esthetic veneering material (porcelain or composite resin) or metal and resin cement [11,13].…”

“…Although various metal alloy can be used to fabricate fixed partial dentures, titanium presents several advantages as a prosthetic material, such as excellent biocompatibility, good mechanical properties, high corrosion resistance, low density and low cost compared to noble metals [2][3][4][5][6][7][8][9][10][11]. However, problems with porcelain bonding have been reported when titanium is used in metal-ceramic restorations as thick and non-adherent layers of titanium oxide are formed.…”

“…For this reason, particulate filler composite resin materials used on titanium castings as an alternative to porcelain fused to metal restorations for esthetic anterior/posterior restorations [9][10][11][12]. Indirect lightcured composite resins have been extensively used in tooth restoration because they can provide acceptable aesthetics, wear resistance similar to tooth structure, and are easy to manipulate in the laboratory and to repair [3,8,9]. However, one of the problems associated with titanium metal-composite restorations is insufficient ability to bond resin to titanium metal castings.…”

“…Macro-(mesh, beads, rough surface with particles) or micro-mechanical treatments (air-abrasion with alumina particles, electrolytic etching, porous metal coating, and acid etching), chemical treatments (4-META composites, phosphate-based composites) and adhesive layer application (tin plating, titanate coupler, silane coupling, carboxylic monomers, a phosphate monomer) were the only mechanisms for bonding composite materials to metallic substrates [2,3,[6][7][8][9]14]. …”

“…The development of new processing methods-such as lost-wax casting, computer-aided machining and electric discharge machining-has allowed the use of pure titanium and its alloys for dental implants, surgical splints, stents and fasteners, partial denture frameworks, fixed partial dentures and root posts [1][2][3][4][5][6][7][8][9]. Although various metal alloy can be used to fabricate fixed partial dentures, titanium presents several advantages as a prosthetic material, such as excellent biocompatibility, good mechanical properties, high corrosion resistance, low density and low cost compared to noble metals [2][3][4][5][6][7][8][9][10][11].…”
