“…Intra-oral repair of cohesively fractured ceramic crowns with resin composite can be considered a cost and time effective method with the advantage of maintaining the restoration substructure and therefore protecting the underlying tooth 54,55) . The alternative is to replace the crown, removal of which is a difficult process, and producing an aesthetic replacement.…”

The objectives were to evaluate the fracture resistance and stress concentration in zirconia/composite veneered crowns in comparison to zirconia/porcelain crowns using occlusal fracture resistance and by stress analysis using finite element analysis method. Zirconia substructures were divided into two groups based on the veneering material. A static load was applied occlusally using a ball indenter and the load to fracture was recorded in Newtons (N). The same crown design was used to create 3D crown models and evaluated using FEA. The zirconia/composite crowns subjected to static occlusal load showed comparable results to the zirconia/porcelain crowns. Zirconia/composite crowns showed higher stress on the zirconia substructure at 63.6 and 50.9 MPa on the zirconia substructure veneered with porcelain. In conclusion, zirconia/composite crowns withstood high occlusal loads similar to zirconia/porcelain crowns with no significant difference. However, the zirconia/composite crowns showed higher stress values than the zirconia/porcelain crowns at the zirconia substructure.

“…To date, documentation on the clinical performance of repaired restorations is sparse and scanty 10) . Different repair protocols have been developed, and evaluated by researchers, to enhance the functionality, longevity, and esthetics of ceramic restorations: acid etching (e.g., hydrofluoric acid, acidulated phosphate fluoride, and phosphoric acid) 2,[11][12][13][14] , airborne particle abrasion with aluminum oxide 15) , and airborne particle abrasion with silica coating [16][17][18] . However, there is no agreement on which repair system is the efficient one that guarantees favorable clinical outcome 16) .…”

This study evaluated the repair bond strength of a nanohybrid resin composite to a novel CAD/CAM hybrid ceramic based on four intraoral ceramic repair systems. Vita Enamic (VE) CAD/CAM hybrid ceramic was used in this study. Specimens were divided into five test groups according to the repair method performed on the ceramic surface: Gr C (No treatment; control); Gr CZ (Cimara Zircon); Gr PR (Porcelain Repair); Gr CR (Clearfil Repair); and Gr CS (CoJet system). Nanohybrid resin composite (GrandioSO) was packed onto treated ceramic surfaces for adhesion testing using microtensile bond strength test. Debonded specimens were examined with a stereomicroscope and SEM to determine the fracture mode. Data were analyzed using ANOVA and Tukey's HSD test. PR and CZ repair systems significantly enhanced the bond strength of nanohybrid resin composite to VE CAD/CAM hybrid ceramic when compared with the other tested repair systems.

“…The repair is characterized by a faster and low-cost method if compared to replacement of the entire restoration (3)(4)(5). This study has shown that using the correct surface treatment for each ceramic is the key for success in repair procedure.…”

“…The feldspathic ceramics used as veneer are commonly affected by shipping, fracture or excessive wear, mainly when supported by zirconia frameworks (2). In this way, direct repair with a composite resin appears as an attractive alternative due to the low cost, fast resolution, and preservation of supporting structures (3)(4)(5).…”

The aim of this study was to evaluate the efficacy of different surface conditioning methods on the microtensile bond strength of a restorative composite repair in three types of dental ceramics: lithium disilicate-reinforced, leucite-reinforced and feldspathic. Twelve blocks were sintered for each type of ceramic (n=3) and stored for 3 months in distilled water at 37 °C. The bonding surface of ceramics was abraded with 600-grit SiC paper. Surface treatments for each ceramic were: GC (control) -none; GDB -diamond bur #30 µm; GHF -hydrofluoric acid (10%); GT-tribochemical silica coating (45-μm size particles). Treatments were followed by cleaning with phosphoric acid 37% for 20 s + silane + adhesive. The composite resin was used as restorative material. After repair, samples were subjected to thermocycled ageing (10,000 cycles between 5 °C and 55 °C for 30 s). Thereafter, the samples were sectioned into 1.0 mm 2 sticks and tested for microtensile bond strength with 0.5 mm/min crosshead speed. Data were compared by two-way ANOVA and Tukey's test (α=0.05). The superficial wear with diamond bur proved to be suitable for feldspathic porcelain and for leucite-reinforced glass ceramic while hydrofluoric acid-etching is indicated for repairs in lithium disilicate-reinforced ceramic; tribochemical silica coating is applicable to leucite-reinforced ceramic. Predominance of adhesive failures was observed (>85% in all groups). In conclusion, the success of surface treatments depends on the type of ceramic to be repaired.
