Effect of toothbrushing with different manual toothbrushes on the shear bond strength of orthodontic brackets
(2010-07-01)
The aim of this study was to evaluate the effect of brushing with a Colgate 360° or Oral B Indicator 35 toothbrush on the shear bond strength of orthodontic brackets bonded to extracted human teeth. The bristle wear and ...
Interface shear strength of geosynthetics: Evaluation and analysis of inclined plane tests
(ELSEVIER SCI LTD, 2009)
The inclined plane test (IPT) is commonly performed to measure the interface shear strength between different materials as those used in cover systems of landfills. The test, when interpreted according to European test ...
Comparative in vitro study of the shear bond strength of brackets bonded with restorative and orthodontic resins
(Sociedade Brasileira de Pesquisa Odontológica (SBPqO), 2011-01-01)
The aim of this study was to evaluate the shear bond strength of brackets bonded with different restorative systems and compare it with that afforded by an established orthodontic bonding system. Seventy human bicuspids ...
Orthodontic brackets removal under shear and tensile bond strength resistance tests - a comparative test between light sources
(Wiley-v C H Verlag Gmbh, 2008-01-01)
We have investigated if a new LEDs system has enough efficient energy to promote efficient shear and tensile bonding strength resistance under standardized tests. LEDs 470 +/- 10 nm can be used to photocure composite during ...
Shear bond strength of resin cement bonded to alumina ceramic after treatment by aluminum oxide sandblasting or silica coating
(2011-10-01)
Purpose: To evaluate the shear bond strength and bond durability between a dual-cured resin cement (RC) and a high alumina ceramic (In-Ceram Alumina), subjected to two surface treatments. Materials and Methods: Forty ...
Comparison of the shear bond strengths of conventional mesh bases and sandblasted orthodontic bracket bases
(2009-10-01)
This study aimed to compare in vitro the shear bond strength between metallic brackets (Abzil) with conventional mesh bases and metallic brackets with bases industrially sandblasted with aluminum oxide using three adhesive ...
Evaluation of shear bond strength and shear stress on zirconia reinforced lithium silicate and high translucency zirconia
(2018-01-22)
This study evaluated the shear stress distribution on the adhesive interface and the bond strength between resin cement and two ceramics. For finite element analysis (FEA), a tridimensional model was made using computer-aided ...
Proposal of a test specimen to evaluate the shear strength of vertical interfaces of running bond masonry walls
(NATL RESEARCH COUNCIL CANADA-N R C RESEARCH PRESS, 2008)
There is no normalized test to assess the shear strength of vertical interfaces of interconnected masonry walls. The approach used to evaluate this strength is normally indirect and often unreliable. The aim of this study ...
Shear bond strength of aesthetic materials bonded to Ni-Cr alloy
(Elsevier B.V., 2003-03-01)
Objectives. This study was undertaken to evaluate the shear bond strength of four materials used as aesthetic material bonded to Ni-Cr alloy.Methods. Sixty-eight alloy discs were prepared and divided equally into four ...
