Evaluation and comparison of the effect of different surface treatment modifications on the shear bond strength of a resin cement to titanium: An in vitro study

Abstract

The purpose of this study was to evaluate and compare the effect of grit blasting, chemical treatment, and application of alloy primer combinations on the shear bond strength (SBS) of a self-cure resin cement to titanium surface.Materials and Methods:Fifty cast commercially pure titanium discs (9 mm × 2 mm) were divided into five groups (n = 10), which received the following surface treatments: Control group (no surface treatment), group 1 (grit blasting using 110 µm Al2O3 particles and application of alloy primer), group 2 (grit blasting using 110 µm Al2O3 particles and chemical treatment using 1N HCl), group 3 (chemical treatment using 1N HCl and application of alloy primer), and group 4 (Grit blasting using 110 µm Al2O3 particles, chemical treatment using 1N HCl and application of alloy primer). Superbond C and B resin cement was applied to the treated titanium surfaces including controls. SBSs were determined after thermocycling for 5000 cycles. Data (megapascal) were analyzed by ANOVA and Bonferroni test.Results:Group 4 (grit blasting using 110 µm Al2O3 particles, chemical treatment using 1N hydrochloric acid, and application of alloy primer) produced the highest bond strength followed by group 1, group 3, group 2, and the control group which showed the least bond strength.Conclusion:(1) Air-abrasion with alumina particles increases the micromechanical retention of the resin to titanium. (2) The alloy primer promotes wettability, which increases the adhesive bonding of resin cement to titanium. (3) Chemical treatment using hydrochloric acid effectively pretreats the titanium surface thereby increasing the SBS values.

The Comparison of Different Surface Preparation Methods in Terms of Shear Bond Strength of Tri-ceram Porcelaintitanium Alloy

“…The success of the porcelain-fused-alloy restoration depends widely on the strong bonding between porcelain and the titanium. In the current work, the titanium surface treatment with 10% HCl has provided strong SBS values, and acid etching was found to be more effective than alumina airborne-particle abrasion, laser etching and C. In fact, acid etching has been indicated as mostly quite effective method for increasing SBS in titanium-porcelain system (1)(2)(3)(4)12,16,18). Therefore, the present results obtained with 10% HCl are in consistent with the previous studies related to surface acid treatment.…”

“…48% H 2 SO 4 ) different than HCl (3,12,16). On the contrary, even 1 N (about 3%) HCl is known to erodes the titanium surface effectively and to provide increasing SBS values (18).…”

“…Several studies have been carried out to investigate the effects of surface preparation on shear bond strength (SBS) of metal-porcelain complex. The SBS values for titanium-porcelain complex have been evaluated by several methods such as acid etching (1-17), alumina airborne-particle abrasion (7)(8)(9)(10)(11)(12)(13)(14)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30), laser irradiation (6,15,16,22,27,30), fluoride etchant application (8,9,12,13), nanotechnology (10), machining/milling/thermic treatments (8,9,13,23,26,31) and cooperative use of simple surface preparation methods (2)(3)(4)9). The SBS has also been investigated for the influence of various parameters such as acid types and concentrations (2)(3)(4)…”

“…In the other words, a completed picture has not been obtained yet. Therefore, the studies on the SBS of titanium-ceramic complex are still interest of clinical research, and such studies appear frequently on the recent literature (5,10,11,13,14,18,(28)(29)(30)35,42). For these reasons, a new study done by using the simple surface preparation methods and specific parameters may contribute to complementary studies in this field.…”

Evaluation of the effect of silicone residue after different surface treatments on shear bond strength of glass ionomer cement to the dentin surface

“…[ 13 17 18 21 22 23 ] Group II revealed the presence of residual silicone film interspersed with smear layer. Hence, the reduced SBS[ 24 25 ] indicating adhesive type of failure. Group III revealed cracking and the presence of GIC remnants on the dentin surface correlating with the cohesive type of failure.…”
