“…The resulting compressive stress state manifests as a significantly increased characterised mean deflection of the polished reference surface, demonstrated as increased convexity (Table 1). Therefore the extrapolation of Nathanson's theory by Rosenstiel et al [9] which related polymerisation shrinkage of resin-based cements to a beneficial compressive M a n u s c r i p t 17 stress state across the entire ceramic defect integral is in alignment with the results of the current study. This is possibly emphasised further in the bi-axial flexure strength results where in excess of a two-fold strength increase was observed following resincement coating -independent of the output intensities used in the current investigation.…”

“…Ceramic surfaces are frequently alumina particle air-abraded [2,3] or acid-etched [4,5] to create a micro-mechanically retentive surface conducive to bonding to the dental cement. It has been reported for several classes of ceramic material that pre-cementation surface modification impacts on the flexural strength [3,[5][6][7][8][9]. The observed strength modification is often accounted for by Griffith's theorem relating the strength of a brittle system to the severity of the critical defect [10].…”

Objectives: The hypothesis tested was that processing, pre-cementation and cementation techniques can modify the profilometrically measured deformation of a ceramic.Methods: Three-point flexural moduli of a resin-cement were characterised following light irradiation at 430 and 180 mWcm-2. Thirty IPS e.max Ceram discs were prepared and a reference surface produced by polishing. Discs were annealed, alumina particle air abraded and resin-coated. Profilometric evaluation was performed following each pre-cementation or cementation operative technique using a contact diamond stylus profilometer. Bi-axial flexure strength of the resin-coated discs, light irradiated at 430 and 180 mWcm-2 (Groups A and B), and the un-coated discs (Group C) was determined. Data were analysed by a one-way analysis of variance with post-hoc Tukey tests (P<0.05), or repeat measure analyses when appropriate.

“…For the double layered specimens, biaxial flexural strength was calculated using the following equations with the porcelain on the compression side (top layer; porcelain) and TZP on the tension side (bottom layer; TZP), and following conditions: Young's modulus 210 GPa for TZP and 70 GPa for porcelain, and Poisson's ratio 0.25 ( Fig. 1) 7,26) .…”

This study aims to investigate the effectiveness of monolithic translucent TZP with different colors and porcelain-layered TZP by evaluating their colors and strengths. Different mixing ratios of Zpex to Zpex-Yellow as translucent TZP, conventional opaque TZP (TZ-3YB-E) (Tosoh, Tokyo) as a control, and veneering porcelain (CERABIEN ZR, body porcelain, Noritake, Tokyo) with shade A3 as a typical shade. Disk-shaped specimens of 13 mm diameter and 1.5 mm thickness were prepared. These specimens were observed under reflected and transmitted light, and the translucency parameter (TP) values were measured. Strength was also evaluated with flexural strength in a biaxial bending test. The TP values of the monolithic TZP, Zpex100>Zpex70>Zpex50>TZ3YB, were larger in this order. The flexural strength of all the monolithic TZP showed approximately 1,000 MPa. It is suggested that colored translucent TZP is clinically useful when used as monolithic restorations.

“…However, there is significant laboratory and clinical evidence to suggest that the application of adhesive resin cement can act to reinforce ceramic restorations and improve clinical longevity [3][4][5][6][7]. The clinical performance of resin bonded ceramic inlays, onlays, crown and veneers have been well documented [8][9][10][11][12][13][14][15] and in some cases have been shown to compete favorably with cast metal restorations [16].…”

The goal of this work is to quantitatively examine the effect of adhesive resin cement on the probability of crack initiation from the internal surface of ceramic dental restorations. The possible crack bridging mechanism and residual stress effect of the resin cement on the ceramic surface are examined. Based on the fracture-mechanics-based failure probability model, we predict the failure probability of glass-ceramic disks bonded to simulated dentin subjected to indentation loads. The theoretical predictions match experimental data suggesting that both resin bridging and shrinkage plays an important role and need to be considered for accurate prognostics to occur.
