Novel approach to improved silanation of zirconia
Objective : The overall goal of this research was to chemically modify the surface of zirconia dental ceramics with a Si x O y seed layer to increase adhesive bonding…
Detection of free radical concentrations of three self-adhesive resin cements
Objectives : The free radical concentrations of resin materials do not only compromise the material polymerization properties but also may impact its overall biocompatibility due to higher concentrations of residual…
Effect of particle deposition protocols on flexural strength of zirconia after cyclic loading
Objectives: Although air-particle abrasion delivers advantages for improved adhesive strength of resin cements to yttria-stabilized tetragonal-zirconia-polycrystalline (zirconia), it is not widely studied whether this process impairs the mechanical properties of…
Hardness of soft liners after long-term water storage
Objectives : Denture soft liner materials are known to harden during clinical use. This study evaluated hardness changes in a variety of commercial soft liner products during long-term water storage….
Effect of silane treatment on the surface of indirect composite
Objectives : Proper cementation protocol is critical to the success of indirect restorations. Recommendation in materials and techniques however vary by manufacturer. The purpose of this study was to study…
Effect of specimen geometry on mechanical properties of a porcelain
Objectives : The objective of this study was to compare the Weibull parameters (characteristic strength, σ 0 , and Weibull modulus, m ) and slow cracking growth (SCG) parameters (stress…
Three-dimensional finite element modeling of dental implant based on micro-CT
Objectives : To describe one method for the three-dimensional finite element modeling of dental implant by combining micro-CT technique and Mimics software. Materials and methods : One dental titanium implant…
Preliminary histomorphometric comparisons of two implant biomaterials in a rabbit model
Objectives : The purpose of this study was to histomorphometrically compare a noncoated threaded zirconia implant vs. a noncoated threaded titanium implant in a rabbit model. The study tested the…
Strength degradation of dental ceramics after in vitroaging
Objectives : To evaluate the strength degradation of five ceramics (yttria stabilized zirconia, YZ; alumina polycrystal, AL; glass-infiltrated alumina–zirconia, ICZ; and porcelains VM7 and VM9, all from Vita) after in…
Effect of thermo-cycling on resin cement shear bond strength
Objectives : Repeated exposure to cyclic temperatures can result in change of bond strength. The purpose of this study is to determine the difference in shear bond strengths between a…
