TLDR
The mode of failure of resin composites bonded to ceramics has frequently been reported to be cohesive fracture of either ceramic or resin composite rather than separation at the adhesive interface, so this study was designed to question the validity of shear bond strength tests.Abstract:
Since the mode of failure of resin composites bonded to ceramics has frequently been reported to be cohesive fracture of either ceramic or resin composite rather than separation at the adhesive interface, this study was designed to question the validity of shear bond strength tests. The reasons for such a failure mode are identified and an alternative tensile bond strength test evaluated. Three configurations (A, conventional; B, reversed; and C, all composite) of the cylinder-on-disc design were produced for shear bond strength testing. Two-dimensional finite element stress analysis (FEA) was carried out to determine qualitatively the stress distribution for the three configurations. A tensile bond strength test was designed and used to evaluate two ceramic repair systems, one using hydrofluoric acid (HF) and the other acidulated phosphate fluoride (APF). Results from the shear bond strength tests and FEA showed that this particular test has as its inherent feature the measurement of the strength of the ...read more

TL;DR: Available data suggest that resin bonding to these materials is less predictable and requires substantially different bonding methods than to silica-based ceramics, and further in vitro studies, as well as controlled clinical trials, are needed.

TL;DR: Conditioning the INC-ZR ceramic surfaces with silica coating and silanization using either chairside or laboratory devices provided higher bond strengths of the resin cement than with airborne particle abrasion using 110 microm Al(2)O(3).

TL;DR: Chairside silica coating and silanization provided higher resin-resin bond strength values compared to acid etching with phosphoric acid followed by adhesive resin applications and Citric acid was the least aggressive aging medium.

A critique of bond strength measurements
TL;DR: It is shown that tensile and shear bond strengths are highly dependent on the geometry of the test arrangement and the materials involved, and there is a need for the standardization of test procedures for the measurement of bond strengths so that a universally valid comparison between different bonding agents can be performed.

The Effect of Local Interfacial Geometry on the Measurement of the Tensile Bond Strength to Dentin
TL;DR: A standardized method for the measurement of dentin bond strength is urgently needed and must take modifications of the local stress distribution at the adhesive/dentin interface into account if results from different testing centers are to be directly comparable.

TL;DR: Porcelain-fused-to-metal bond tests were analyzed for interfacial shear stress distribution using finite-element stress analysis and a high probability of tensile failure within porcelain or the interfacial region was found.
