“…The material characteristics of ceramics have been shown to significantly depend on prior thermal and mechanical fatigue loading 4) . Four factors have been identified to mainly influence the fracture resistance of all-ceramic restorations: restoration design, tooth preparation, cementation and material thickness [5][6][7][8][9] . The fracture resistance can be increased by an ideal combination of these four factors, however, the factors restoration material and material thickness have been reported to be of primary importance 10) .…”

The fracture behavior of CAD/CAM fabricated crowns was investigated as a function of material thickness for six silicate ceramic materials: Mark II, e.max CAD, Celtra Duo milled, Celtra Duo fired, Suprinity, Enamic. Crowns with thicknesses 0.5/1.0/1.5 mm were fabricated with CEREC and adhesively seated to dies fabricated with stereolithography technology (n=144). Thermomechanical loading and fractural loading was performed. Statistical analysis was done with one-way ANOVA and post-hoc Scheffé test. For 1.5 mm, all crowns survived fatigue testing, for 1.0 mm, survival was 100% only for materials e.max CAD and Suprinity. For 0.5 mm, best survival rate was 37.5% for Suprinity. Maximum fractural loading significantly varied among the groups. For 0.5 mm, highest value was found for Suprinity (660.1 N). Mark II showed lowest values for 1.0 mm (482.0 N), and 1.5 mm groups (634.8 N). e.max CAD showed highest values for 1.0 mm (774.2 N), and 1.5 mm groups (1,240.8 N).Keywords: Feldspathic ceramic VITA Mark II, Lithium disilicate ceramic e.max CAD, Zirconia-reinforced lithium silicate ceramic Celtra Duo and VITA Suprinity, Hybrid ceramic VITA Enamic, CERECColor figures can be viewed in the online issue, which is available at J-STAGE.

“…Luting agents should provide an adequate seal between the tooth and restoration to prevent the ingress of bacteria at the margins, while increasing fracture resistance of the restored tooth and restoration. 1 Many types of luting agents exist for the retention of fixed ceramic prostheses: contemporary zinc phosphate cements, glass-ionomers, resin-modified glass-ionomers and resin-based cements. Various investigations have reported that resin-based luting agents improve the retention and efficacy of indirect ceramic restorations, [2][3] particularly the provision of increased fracture resistance and an acceptable marginal seal of the ceramic restoration when compared to contemporary cements.…”

This study investigates the efficacy of modern "self-adhesive" luting cements on a zirconia-based ceramic following various surface preparations SUMMARY Objectives: To investigate the bond strength of modern "self-adhesive" resin cements to a zirconium-based dental ceramic following different surface preparations and storage conditions. Methods: The surface of zirconium-based ceramic discs (12 x 2 mm) were either left untreated, prepared using alumina grit-blasting or tribochemical treatment. Resin composite cylinders were bonded to ceramic specimens using Panavia-F, RelyX Unicem or Maxcem resin cements. The shear bond strength of specimens (n=10) was tested "dry," following 24-hour water immersion or a thermocycling regime.Results: For each surface preparation, a significant reduction in bond strength following 24-hour water immersion and thermocycling compared to "dry" storage conditions was identified for both Panavia-F and Maxcem. However, Unicem specimens exhibited statistically similar SBS values for tribochemically-treated specimens stored dry following 24-hour water immersion or thermocycling (11.7 ± 1.3, 14.1 ± 6.3 and 11.7 ± 4.9 MPa, respectively) (p>0.05). No significant differences in bond strength were identified for Panavia-F or Unicem specimens for any surface preparation following the thermocycling regime (p>0.05). In contrast, for each surface preparation following thermocycling (p<0.001), Maxcem exhibited a significant decrease in SBS Conclusions: The pre-treatment of a zirconiumbased ceramic surface with grit-blasting and tribochemical treatment improves the bond strength of resin cements. Following "wet" storage conditions, Panavia-F and Unicem demonstrated superior bond strength compared with Maxcem. Differences in ceramic surface preparation and the chemistry of resin cements will affect the nature of the bonding mechanism and durability of the adhesive layer.

“…The laboratory fracture resistance of dentine bonded crowns has been assessed and considered satisfactory, 1,3,4 and the aesthetics of dentine-bonded allceramic restorations has been considered to be good, 5 possibly because of the transmission of light through the restoration because the resin-composite luting materials employed in the technique 6 are more translucent than conventional acid-base luting materials. Marginal seal has been considered satisfactory.…”

Aim This paper reports a prospective evaluation of 59 dentine-bonded crowns placed in a dental school environment for patients, a majority of whom were suffering from tooth substance loss. Results Forty-eight crowns (83%) were available for examination, with their mean age since placement being 3.9 years. The mean age of the patients in whom the crowns were placed was 37.5 years. Three crowns had failed due to porcelain fractures, an overall failure rate of 6%. Two of the failures were minimal cracks of which the patient was unaware, and one, in an upper premolar tooth, because of crown fracture. No secondary caries was noted, incidence of pulp symptoms or pulp death was nil, and margins were rated as 'excellent' in 42 crowns (86%). Conclusion The dentine bonded crowns assessed in this study showed excellent retention and low incidence of fracture at four years. This technique would appear to be suitable for a variety of clinical indications, including treatment of tooth substance loss, although the results presented in this study are relatively short term in relation to the anticipated life of restorations.
