Can the Application of Multi-Mode Adhesive be a Substitute to Silicatized/Silanized Y-TZP Ceramics?

Abstract

This study evaluated the effectiveness of a multi-mode adhesive (SBU-Scotch Bond Universal/3M) as a substitute for silica coating and silane application on the bonding of zirconia ceramics to resin cement. One-hundred and twenty sintered zirconia ceramic blocks (5 x 5 x 5 mm) were obtained, finished by grounding with silicon carbide paper (#600, #800, #1000 and #1200) and randomly divided into 12 groups (n=10) in accordance with the factors “surface treatment” (ScSi - silicatization + silanization; ScSBU - silicatization + SBU; SBU - SBU without photoactivation and SBUp - SBU photoactivated) and “ceramic” (Lava / 3M ESPE, Ceramill Zirconia / Amann Girrbach and Zirkonzahn / Zirkonzahn). Dual resin cement cylinders (RelyX Ultimate/3M ESPE) were subsequently produced in the center of each block using a silicon matrix (Ø=2 mm, h=5 mm) and photoactivated for 40 s (1200 mW/cm2). The samples were stored for 30 days in distilled water (37ºC) and submitted to shear bond strength test (1 mm/min, 100 KgF). Data (MPa) were analyzed under ANOVA (2 levels) and Tukey test (5%). Complementary analyzes were also performed. ANOVA revealed that only the factor “surface treatment” was significant (p=0.0001). The ScSi treatment (14.28A) promoted statistically higher bond strength values than the other ScSBU (9.03B), SBU (8.47B) and SBUp (7.82B), which were similar to each other (Tukey). Failure analysis revealed that 100% of the failures were mixed. The silica coating followed by the silanization promoted higher bond strength values of resin cement and ceramic, regardless of the zirconia ceramic or SBU.

Effect of surface treatments on the bond repair strength of resin composite to different artificial teeth

“…Shear, microshear, tensile and microtensile tests can be used to evaluate bond strength. Despite the limitations of the shear test, sample standardization and easy preparation, as well as suitable laboratory equipment make this test a commonly used methodology to determine the adhesive strength of dental materials [12,15].…”

“…And, when followed by the application of the adhesive system, the higher bond strength values were achieved. A bonding agent has long been used with composite resin in restorative dentistry [12]. It improves surface wettability by causing the resin infiltrate into microscopic surface irregularities [8,17].…”

“…After, each tooth was sectioned into 4 parts that were embedded in chemically activated acrylic resin (Jet-Classic, São Paulo, Brazil) prior to receive different surface treatments. The groups were randomly assigned according to the surface treatment: subgroup c-did not received any surface treatment; subgroup a-application of an adhesive system layer (Signum Connector, Heraeus Kulzer, GER) polymerized for 40 s as per the manufacturer's instructions (1200 mW/cm 2 -Radii Cal, SDI, Australia); subgroup S-sandblasting with Al 2 O 3 particles (50 µm) [12] for 10 s with a distance of 10 mm and a pressure of 2.8 bar; and subgroup Sa-sandblasting followed by an adhesive system application. The group's distribution is summarized in Table 1, and Fig.…”

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

“…The association of methods has shown better bond strength results than their separate use. Thus, aluminum oxide sandblasting followed by the application of zirconia primers, as well as tribochemical silica coating followed by silanization, are the two most popular methods for bonding to zirconia ceramic [19,22,23]. However, the most suitable clinical protocol is still under discussion for zirconia ceramic [20].…”

Cerámicas: una actualización

“…Por su inercia química muchos investigadores sugieren realizar tratamientos en la superficie interna de ella para mejorar su adhesión. Tratamientos como el arenado triboquímico (Sistema Cojet o Rocatec 3M ESPE, St.Paul, MN; EEUU) es actualmente el gold estándar cuando de adherirla con cementos resinosos se trata [56][57][58] .…”
