“…The clinically acceptable marginal gap for CAD/CAM generated restorations are within 100 μm [24][25][26][27]. Debonding of all-ceramic fixed restorations was common in-vivo studies [50,51]. This study was performed to compare the vertical marginal gap and retention of full coverage ceramic FPDs and 3 most common designs of ceramic inlay retained FPDs.…”

“…The size of these preparation features depends on the size of the tooth. The tested design is the most used in CIRPFDs [10][11][12]50,53,58]. The dimension of the full coverage all ceramic FPDs were constructed according to Rosenstiel et al (2006) [65].…”

“…A zirconia ceramic was used due to the ability of yttriatetragonal zirconia polycrystal to prevent crack propagation and thus yield excellent mechanical performance and superior strength and fracture resistance, compared to other ceramics [11,14,15] and the production of strong inlay-anchored FPDs [31,50,68,69]. Zirconia based ceramic IRFPDs demonstrates higher fracture resistance than glass ceramic [12,70].…”

“…Dental literature is poor on studying the retentive strength of the inlay retained ceramic FPDs. Ohlmann et al (2008) [50] in a preliminary clinical study on all-ceramic inlay-retained fixed partial dentures, reported that 6 out of 13 inlay retained FPDs were subjected to debonding. .…”

“…Zirconia ceramic is nowadays widely used as a framework material in full-coverage crowns and fixed partial dentures (FPDs) due to its high flexural strength (900-1200 MPa) and fracture toughness (5-7 MPa·m 1/2 ) [4]. However, clinical research and practice have reported high incidence of veneer chipping and fracture in all major brands of porcelain-fused-to-zirconia (PFZ) systems, particularly in posterior restorations [5][6][7][8][9][10][11][12][13][14]. Examples of veneer chipping and fracture in porcelain fused to zirconia (PFZ) prostheses, after 6 months intra-oral service and mouth-motion fatigue loading in vitro, are shown in Fig.…”

Objectives-Compressive stress has been intentionally introduced into the overlay porcelain of zirconia-ceramic prostheses to prevent veneer fracture. However, recent theoretical analysis has predicted that the residual stresses in the porcelain may be also tensile in nature. This study aims to determine the type and magnitude of the residual stresses in the porcelain veneers of fullcontour fixed-dental prostheses (FDPs) with an anatomic zirconia coping design and in control porcelain with the zirconia removed using a well-established Vickers indentation method.Methods-Six 3-unit zirconia FDPs were manufactured (NobelBiocare, Gothenburg, Sweden). Porcelain was hand-veneered using a slow cooling rate. Each FDP was sectioned parallel to the occlusal plane for Vickers indentations (n = 143; load = 9.8 N; dwell time = 5 s). Tests were performed in the veneer of porcelain-zirconia specimens (bilayers, n = 4) and porcelain specimens without zirconia cores (monolayers, n = 2).Results-The average crack lengths and standard deviation, in the transverse and radial directions (i.e. parallel and perpendicular to the veneer/core interface, respectively), were 67 ± 12 μm and 52 ± 8 μm for the bilayers and 64 ± 8 μm and 64 ± 7 μm for the monolayers. These results indicated a major hoop compressive stress (~40 to 50 MPa) and a moderate radial tensile stress (~10 MPa) in the bulk of the porcelain veneer.Significance-Vickers indentation is a powerful method to determine the residual stresses in veneered zirconia systems. Our findings revealed the presence of a radial tensile stress in the overlay porcelain, which may contributed to the large clinical chip fractures observed in these prostheses.

The purpose of this study was to evaluate the effect of various surface treatments on the shear bond strength of Y-TZP (Yttria-Tetragonal Zirconia Polycrystal) ceramics with zirconia primer and two different resin cements both containing 10-methacryloyloxydecyl dihydrogen phosphate (MDP). Zirconia blocks (LAVA, 3M ESPE, St. Paul, MN) were polished and assigned to five groups according to the surface treatment: (1) no further treatment (control); (2) airborne abrasion with Al2 O3 particles; (3) Z-PRIME Plus (Bisco, Schaumburg, IL) applied on polished zirconia; (4) Z-PRIME Plus applied on zirconia after airborne abrasion; and (5) tribochemical silica-coating performed with the CoJet system (3M ESPE) followed by application of ESPE®-Sil (3M ESPE). Each group was further divided into one of two resin cements: Panavia F2.0 (Kuraray, Kurashiki, Okayama, Japan) and Clearfil SA Luting (Kuraray). Resin cement placed inside a gel-cap was polymerized on the zirconia surface. Shear bond strength was tested with a universal testing machine at 0.5 mm/min. One-way analysis of variance and paired t-test were done. (p < 0.05), and scanning electron microscope (SEM) images were taken. Zirconia primer applied after airborne abrasion significantly increased the shear bond strength resulting in the highest value for both resin cements. Control groups for both cements showed the weakest value for shear bond strength. No significant differences were found between the shear bond strengths of the individual resin cements applied to zirconia surfaces treated the same way. In conclusion, the combined surface treatment of airborne abrasion followed by a zirconia primer is recommended for zirconia bonding with Panavia F2.0 and Clearfil SA Luting cements.
