Titanium is known as the exotic "space age" metal because of its light weight and high performance in aeronautics. This wonder metal has many advantages as a prosthetic material such as excellent biocompatibility, high strength to weight ratio, low density, sufficient corrosion resistance, and low cost compared to noble alloys and therefore, has gained popularity in dentistry. [1-3] Today titanium and its alloys are used in dental implants, implant frameworks, crowns and bridges, resin bonded bridges, post and core, partial and complete denture frameworks. [4] Many of these restorations are luted with resin cements. The strength of the cement/metal bond is significantly affected by 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 Al 2 O 3 particles and application of alloy primer), group 2 (grit blasting using 110 μm Al 2 O 3 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 Al 2 O 3 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 Al 2 O 3 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.

PURPOSE To evaluate the micro-shear bond strength (μSBS) of different bonding protocols to commercially pure titanium (CP Ti) using two universal adhesives and Alloy Primer. MATERIALS AND METHODS A total of 120 cubes of CP Ti were airborne-particle abraded and then divided into 6 groups (n = 20 each) according to bonding protocol: (1) Scotchbond Universal (SU; 3M ESPE), (2) Alloy Primer (AP; Kuraray) + SU; (3) G-Premio Bond (GP; GC); or (4) AP + GP. The specimens from groups 1 to 4 were cemented with RelyX Unicem (3M ESPE), while those from groups 5 and 6 were cemented using Panavia F2.0 cement (PAN; Kuraray) without and with prior AP application, respectively. After 24 hours, half the specimens were subjected to μSBS measurement and the other half to thermocycling (5,000 cycles) before testing. Data were analyzed using Shapiro-Wilk, two-way analysis of variance, Games-Howell, and independent sample t test (α = .05). RESULTS The μSBS values obtained from the AP + SU group were signi...
The Micro-Shear bond strength of different cements to commercially pure titanium
Journal of Clinical and Experimental Dentistry, 2019
Background: The most appropriate luting agent for attaching the prefabricated Ti-based insert of hybrid abutments to its ceramic component has not yet been determined. This study was done aimed at examining the micro-shear bond strength (μSBS) of different cements to commercially pure titanium (Cp Ti). Material and methods: A total of 100 milled cubes of Cp Ti was airborne-particle abradedusing 250 μm aluminum oxide particles. Specimens were then divided into 5 groups (n=20) according to the type of resin cement used: (1) Panavia F.2, (2) Rely X U200, (3) Panavia SA LUTING Plus, (4) GC Fuji I, and (5) GC FujiCEM 2. After 24h storage, half of the samples were subjected to 5000 cycles of thermal aging. Next, the bonded samples were tested in the micro-shear mode. Data (MPa) were analyzed using a two-way ANOVA and the post hoc Tukey test (α=0.05). After debonding, each sample was examined for the failure mode classification. Results: The highest μSBS value in the study cements was obtained for Panavia F.2 cement (P<0.001) with no significant difference with Rely X U200 (P=0.07). The μSBS values of both GI-based cements were significantly lower than those of resin cements. Thermal aging decreased the μSBS values of all groups (p=0.003) significantly. The mainly occurred failure mode in all groups was the adhesive feature. Conclusions: Resin cements demonstrated acceptable bonding to Cp Ti, yet Gl-based cements did not. From among the cements examined, Panavia F.2 can be considered as thebest option for bonding to Ti.
Effect of Thermocycle and Bonding Agents on the Bond Strength of Titanium-resin Cements
Bezmialem Science, 2021
Objective: This research aimed to evaluate the effect of different resin cement (RC) types, compare the effect of surface treatments and bonding applications and evaluate the effect of thermal cycling on bond strengths to Titanium (Ti) surfaces. Methods: A total of 240 Ti discs (10x3 mm) were randomly divided into two groups. Half of the specimens were sandblasted with 110 µm Al 2 O 3 particles, whereas the other half had no surface treatments (non-treated). Both sandblasted and non-treated specimens of each surface treatment type were divided into five subgroups, which received one of the following surface conditions and luting selfadhesive resin cement: (a) Panavia SA Cement, (b) Clearfil SE Bond + Panavia SA Cement, (c) RelyX U200, (d) Single Bond Universal + RelyX U200 and (e) MIS Crown Set Cement. A mould with a 4-mm diameter and 2-mm thickness was applied to the central region of the specimens. Each group was divided into subgroups, according to whether performing thermocycling or not. The shear bond tests were conducted at a crosshead speed of 1 mm/min. Data (N) were analysed using one-way analysis of variance and Tukey's honestly significant difference tests (p<0.05). Results: The sandblasted + bonding agent groups provided higher shear bond strength than the non-treated groups for all RC types (p<0.05). Sandblasted Clearfil SE Bond + Panavia SA Cement (non-thermocycled) showed the highest values (182.761±41.55), whereas the MIS Cement (17.681±9.33) and Panavia SA Cement Amaç: Bu çalışmanın amacıfarklı rezin simanların, kumlama yüzey işleminin, bonding ajanlarının ve yaşlandırmanın Titanyum (Ti)rezin siman (RS) arasındaki makaslama bağlanma dayanımına etkisinin değerlendirilmesidir.

Quintessence international (Berlin, Germany : 1985), 2007
To assess the effect of metal conditioners on the bond strength between resin cements and cast titanium. Commercially pure titanium (99.56%) was cast using an arc casting machine. Surfaces were finished with 400-grit silicon carbide paper followed by air abrasion with 50-Microm aluminum oxide. A piece of double-coated tape with a 4-mm circular hole was then positioned on the metal surface to control the area of the bond. The prepared surfaces were then divided into 4 groups (n=10): G1, unprimed Panavia F; G2, Alloy Primer-Panavia F; G3, unprimed Bistite DC; G4, Metaltite-Bistite DC. Forty minutes after insertion of the resin cements, the specimens were detached from the mold and stored in water at 37 degrees C for 24 hours. Shear bond strength was performed in a testing machine (MTS 810) at a crosshead speed of 0.5 mm/min. Data were analyzed using ANOVA and Tukey's test with a .05 significance level. The fractured surfaces were observed through an optical microscope at 103 magni...
