Shear Bond Strength of Metal-Acrylic Resin

Check if the same lab product or an alternative is used in the 5 most similar protocols

Each bonded specimen was embedded in an acrylic resin mold, and then placed inside an ISO/TR 11405 shear tests jig. The shear bond strengths were measured using a universal testing machine (AGS-10kNG, Shimazu Corp., Kyoto, Japan), with a load applied in the direction parallel to the bonding surface at a crosshead speed of 0.5 mm/min (Figure 2). The shear bond strength was calculated by dividing the force, at which bond failure occurred, by the bonding area.
The debonded surfaces were examined with an optical microscope (SMZ-10, Nikon Corp., Tokyo, Japan) at a magnification of ×45 to evaluate possible failure types. The observed failure modes were classified as either (i) an adhesive failure at the metal–acrylic resin interface, or (ii) a mixed failure of an adhesive failure at the metal–acrylic resin interface and a cohesive failure of the acrylic resin.

The flexural strength was determined using 3-point bending with bar specimens (n=10/group) according to ISO 6872, but without 45° edge chamfer. All specimens were loaded with the treated surface in tension. Tests were performed using a universal testing machine (AGS-10kNG, Shimazu Corp.; Kyoto, Japan) with a cross-head speed of 1.0 mm/min, and a span of 20.0 mm. The fracture load was recorded in N, and the flexural strength was calculated in MPa.

The FS and FM were tested according to ISO 4049: 2009 standards. PMMA resin specimens (2 × 2 × 25 mm) were prepared in a rectangular stainless steel mold. After curing, the specimens were removed from the mold and were placed in a water bath at 37 °C for 24 h. The three-point bending test was performed using a universal testing machine (AGS-10kNG, Shimadzu, Kyoto, Japan) at a cross-head speed of 0.05 mm/min at a controlled room temperature. The FS and FM were calculated by the following equations, respectively:

FS = 3 FL / 2 {wh}^{2}

FM = {kL}^{3} / 4 {wh}^{3}

where F is the maximum load (N) exerted on the specimen, L is the distance (mm) between the supports (20 mm), w is the width of the specimen, h is the thickness of the specimen, and k is the slope of the line segment of the load/displacement graph. Mean FS and FM were calculated in megapascals (MPa). After testing, the microstructure of the fractured surfaces obtained from mechanical testing was observed with Fe-SEM.

Femur Biomechanical Evaluation Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols

At 6 months, three animals in each group were sacrificed, and their femurs were harvested and stored at -80 °C. The distal 1/3 of each femur was resected and fixed onto a self-designed mechanical clamping apparatus, which engaged with a universal mechanical testing machine (AGS 10 KNG, SHIMADZU, Japan). The femur was kept in a physiological standing position by adjusting the clamping apparatus. The physiological position was defined that the femur has an adduction angle of 9.6 degree, and the femur axis was set paralleled with coronal plane. A pressor probe was designed to press the femoral head, which had a concave spherical shape tangent to the femoral head. Each femoral head was applied to a vertical press with a speed of 2 mm/min, and each press-displacement curve was drawn according to primary data.

To assess the SBS, “Instron” universal testing machine AGS-10k NG (SHIMADZU) was used, and the measurement was carried at Indian Institute of Chemical Technology, Hyderabad [Figure 1]. The acrylic block with crown part facing upward was placed in the lower crosshead, and the debonding force was applied parallel to the bracket base. A loop made of 0.8 mm stainless steel attached to the upper crosshead was used to apply shear force to debond the bracket. The loop portion was attached below the gingival tie wing of the bracket [Figure 2]. The shear bond was measured at 24 h after bonding.

After the specimen harvest, the ten samples in each group were quickly introduced to the biomechanical pullout test using a universal material testing system (AGS-10KNG; Shimadzu, Kyoto, Japan). The compression speed was set at 2 mm/min. The displacement versus force was recorded to calculate the maximal pullout force.

At 6 months, another 4 animals were sacrificed, and the femurs were harvested and stored at −80 centigrade. The testing process was similar with previous reports [12 (link),13 ]. Briefly, using a self-designed clamping apparatus, the proximal femurs were fixed on a universal mechanical testing machine (AGS 10 KNG, SHIMADZU, Japan). A vertical lord with a speed of 2 mm/Min was applied to each femoral head. Load and displacement data were documented and analyzed.

Powders from samples P1–P15 were mixed with Superacryl monomer (Spofa Dental) in a ratio of 2.2 g of powder and 1 g of liquid. In the dough stage (20 min after mixing the powder and liquid), the materials were placed into the metal forms and polymerized for 30 min at 60 °C and for 1 h in boiling water. Fore flexural strength metal forms dimensions: 2.5 × 10 × 65 mm were used. For each experiment, six samples of each composition were prepared. Totally 96 samples were used for the test, which was performed after 7 days of polymerization. Until testing, samples were stored in distilled water at 37 °C. Flexural strength of the samples was tested using a Shimadzu (AGS 10 kNG; Shimadzu, Japan) compressive strength instrument after entering the dimension of the sample (ISO, 2013 , Raszewski and Jałbrzykowski, 2017 (link)).

According to the ISO 10993-2:1992 animal welfare requirements and approved by the Institutional Animal Care and Use Committee (IACUC) of Xi’an Jiaotong University. Metallic Ti cylinders (2.5 mm in diameters and 10 mm high) with different coatings were implanted into femoral shafts of twenty-four 3-month-old mature New Zealand male rabbits, each 2–3 kg, based on the procedure from our previous work^{28 (link)}. Each coating was deposited on different Ti cylinders, and then each coating was tested in five different rabbits. Eight weeks after implantation, animals were anesthetized, and the implants with attached tissues were removed to be further analyzed. Amount of bone-to-implant contacts (BIC) was obtained from 3–4 sections taken from each endosseous implant.
Biomechanical pull-out tests helped to determine strength of bone-implant integration. Femora with implants, embedded in PMMA, were collected 8 weeks after the healing. Top of each implant was positioned horizontally. Each implant was removed using Shimadzu AGS-10kNG (Japan) test machine by pulling it strictly vertically at 1 mm/min cross-head speed. Maximum pull-out force was calculated from the load-displacement curve.

An “Instron” universal testing machine AGS-10k NG (SHIMADZU) was used to measure the SBS. The crosshead of Instron moved at the uniform speed of 1 mm/min. The acrylic block was positioned in the lower crosshead with the crown portion of teeth facing upward. The debonding force was applied in a direction parallel to the bracket base. A loop made of 0.8 mm stainless steel was attached to the upper crosshead to apply shear force to debond the bracket. The loop portion was attached below the gingival tie wing of the bracket. The data were analyzed by SPSS software (Statistical Package for Social Sciences, version 20.0, Chicago, Illinois, USA), and then the normal distribution of the data was confirmed by Kolmogorov-Smirnov test. One-way ANOVA test and Tukey's multiple post hoc procedures were used to compare between groups. In all statistical tests, the significance level was set at 5% (P < 0.05).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
