CO₂ laser dentin surface treatment most effectively increased ceramic shear bond strength

Abstract

CO laser irradiation increases shear bond strength for both CAD/CAM ceramics bonded to dentin.

Effect of Different Surface Treatment Methods on Bond Strength of Dental Ceramics to Dental Hard Tissues: A Systematic Review

“…All the qualified papers investigated the bond strength of dental ceramics to dental hard tissues. Fifteen of these studies described ceramics luted to human dentin [ 7 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ], two described ceramics luted to human enamel [ 30 , 31 ] and one described ceramics luted to the dentin of bovine teeth [ 32 ]. Saker et al performed a comparative study on two human dental tissues: dentin and enamel [ 33 ].…”

“…Furthermore, lithium disilicate glass-ceramic was investigated by Madina et al [ 17 ], feldspathic ceramic by Jetti et al [ 25 ], and monolithic zirconia by Reddy et al [ 20 ], Feng et al [ 23 ], Butler et al [ 29 ], and Zandparsa et al [ 30 ], while Park et al evaluated resin nanoceramics [ 7 ]. Different types of dental ceramics were compared by Kara et al [ 27 ] (feldspathic ceramic, leucite-reinforced hot-pressed ceramic, hot-pressed lithium disilicate ceramic, and zirconia) and Gamal et al [ 28 ] (lithium disilicate and zirconia).…”

“…Other self-adhesive materials evaluated were Multilink Speed, a self-curing composite resin cement, which can be light-cured if desired [ 20 ], and Clearfil Esthetic Cement [ 27 ]. Some studies also investigated the dual-polymerizing adhesive cements, including Multilink Automix [ 16 ], Variolink II [ 25 ], RelyX Ultimate [ 28 ], and Duo-link [ 29 ]. Shahin et al compared the various groups of cements, namely zinc phosphate cement (Hoffmann quick setting), glass-ionomer cement (Ketac Cem Maxi Cap), and adhesive resin cement (Panavia 21) [ 18 ].…”

“…The included studies investigated the techniques of both micromechanical and chemical bonding of ceramics to dental hard tissues. Among the methods applied to achieve micromechanical bonding, there were different kinds of mechanical treatments such as APA [ 7 , 16 , 17 , 18 , 20 , 21 , 23 , 26 , 27 , 28 , 29 , 30 , 31 , 33 ], tribochemical silica coating [ 7 , 16 , 17 , 19 , 21 , 22 , 23 , 24 , 26 , 30 , 33 ], laser irradiation [ 26 , 27 , 28 ], and wet hand grinding [ 16 ]. The second approach utilized for micromechanical bonding was a chemical-based one which involved the use of various acid solutions to etch the conditioned surface [ 7 , 16 , 17 , 20 , 22 , 25 , 27 , 28 , 30 , 31 , 32 , 33 ].…”

Bond to Zirconia Ceramic: Evaluation of Different Primers and a Universal Adhesive

“…Regarding the zirconia ceramic, neither etching with hydrofluoric acid [9,10] nor silane application, such as 3-Methacryloyloxypropyltrimethoxysilane (MPS) are effective [11,12], as this ceramic consists of Yttrium-stabilized Tetragonal Zirconia Polycrystals (Y-TZP) and has no silica in its composition [13]. Thus, various surface treatments have been proposed for zirconia ceramic, such as aluminum oxide sandblasting [9,14], tribochemical silica coating [15,16], selective infiltration-etching technique [17], and CO 2 laser irradiation [18]. Primers containing functional monomers have also been developed which promote bonding to metal oxides such as zirconia [19 -21].…”
