High impact information on Shear Strength

• The shear strength of the primed and 4-META resin-bonded specimens was 37.2 MPa after 50,000 thermocycles, with only a small decrease in bond strength [1].
• Mechanical tests of this bond show that its shear strength is adequate to withstand the stresses likely to be produced by occlusal forces [2].
• Epiphyseal plate shear strength in rats treated with a diphosphonate [3].
• A direct comparison of surface loading, interface shear strength, and interface hydrolytic stability was made between a phosphonate and two siloxane monolayers formed on the native oxide surface of Ti-6Al-4V [4].
• The positive influence of TiO2 addition on the shear strength was revealed [5].

Biological context of Shear Strength

• This study aimed to compare biological properties, including osteoconduction, osseointegration, and shear strength, between plasma-sprayed hydroxyapatite (HA) and HA/tricalcium phosphate (TCP) coatings, using a transcortical implant model in the femora of canines [6].
• Blasting of the surface of titanium-alloy implants did not have an effect on the area of bone formation around the implants, but it did significantly affect the area of bone formation on the implant and the shear strength at the bone-implant interface [7].
• The interface shear stiffness of the two porous systems was equivalent; however, the attachment shear strength of bone growth into carbon-coated porous titanium was significantly increased compared with that of bone growth into the uncoated porous titanium [8].

Anatomical context of Shear Strength

• The purpose of the present study was to evaluate the interface shear strength of unloaded titanium implants with a sandblasted and acid-etched (SLA) surface in the maxilla of miniature pigs [9].
• The interfacial shear strength and bone tissue response was investigated for an arc deposited (AD) commercially pure titanium implant surface, with (AD/HA) and without (AD) plasma-sprayed hydroxyapatite (HA) coating [10].
• Shear strength after ethylenediaminetetraacetic acid conditioning of dentin [11].

Associations of Shear Strength with chemical compounds

• There appeared to be no advantage to multiple layers of beads, and the plasma-sprayed cobalt-chromium and grit-blasted titanium surfaces showed lower shear strength and bone apposition than the other groups [12].
• We have investigated the bone-implant interface shear strength of hydroxyapatite (HA)-coated Ti-6Al-4V (HA-coating A) (roughness average, Ra = 3.4 +/- 0.5 microns) and HA-coated Ti-6Al-4V with a rougher surface (HA-coating B) (Ra = 8.4 +/- 1.8 microns) [13].
• 4-META/MMA-TBB cement had a significantly higher interfacial shear strength than the conventional PMMA cement: 201 N and 90 N, on average, for the implant-cement interface (p<0.01); and 138 N and 89 N, on average, for the bone-cement interface (p<0.01), at 12 weeks [14].
• The interface shear strength of the dense alumina was significantly lower than that of other implants at both 4 and 12 weeks after implantation [15].
• The mean shear strength of the silane-coated samples ranged from 18.2 to 24.1 MPa, and the mean shear strength of the uncoated samples ranged from 7.6 to 15.0 MPa [16].

Gene context of Shear Strength

• The shear strength and rigidity of the wet masses were in the order of EC FP > SMCC 50 > MCC PH101 > HPMC, whereas the elastic recovery was in the opposite order [17].
• Among these four materials, the cells on collagen-coated polystyrene have the highest cell adhesive shear strength and cell detachment surface energy (1500 Pa and 29 pJ on average, respectively), followed by the cells on fibronectin-coated polystyrene (1000 Pa and 16 pJ, respectively) [18].
• Samples oriented with tubules along the long axis of the specimen and tested with shear force applied perpendicular to the tubule direction had significantly higher (p < 0.05; two-way ANOVA) shear strength (78.0 +/- 8.5 MPa) [19].
• The purpose of this study was to compare the retention and shear strength of teeth restored with the Para Plus post (P) and the C post (C1 and C2) systems [20].
• Bone-implant contact and interface shear strength of BMP-2 implants were lower than HA implants at 2 weeks [21].

Analytical, diagnostic and therapeutic context of Shear Strength

• The shear strength of polymethyl methacrylate bonded to titanium partial denture framework material [22].
