“…During the repairing process, clinicians should be careful to eliminate the causes of ceramic fractures, such as bruxism and premature occlusal contacts in the lateral movements. In addition, it is important to apply proper ceramic repairing material and surface treatment for long‐term clinical success …”

“…The filler type of composite has effects on bond strengths of the repair . Large particle size or hybrid‐type composites have been reported to have higher bond strengths than small particle sized composites at the ceramic interface . In this study, nano‐hybrid composite resin was used for the repair.…”

“…However, hydrofluoric acid is a poisonous and caustic liquid that is extremely irritating to the skin and lungs, and concerns about its use intraorally have been reported 26) . Thus, in intraoral repair, phosphoric acid is preferred for etching and decontamination of bonding surfaces 27) . Additionally, phosphoric acid has previously been proposed as a ceramic surface cleaning agent based on the assumption that it is a good organic solvent 27) .…”

Influence of surface treatment of contaminated lithium disilicate and leucite glass ceramics on surface free energy and bond strength of universal adhesives

This study investigates the influence of surface treatment of contaminated lithium disilicate and leucite glass ceramic restorations on the bonding efficacy of universal adhesives. Lithium disilicate and leucite glass ceramics were contaminated with saliva, and then cleaned using distilled water (SC), or 37% phosphoric acid (TE), or hydrofluoric acid (CE). Specimens without contamination served as controls. The surface free energy was determined by measuring the contact angles formed when the three test liquids were placed on the specimens. Bond strengths of the universal adhesives were also measured. Saliva contamination and surface treatment of ceramic surfaces significantly influenced the surface free energy. The bond strengths of universal adhesives were also affected by surface treatment and the choice of adhesive materials. Our data suggest that saliva contamination of lithum disilicate and leucite glass ceramics significantly impaired the bonding of the universal adhesives, and reduced the surface free energy of the ceramics.

The purpose of this study was to evaluate of shear bond strengths between two ceramic repair systems and different ceramic infrastructure materials. One hundred cylindrical specimens of ceramic infrastructure were fabricated with non precious metal alloy, zirconia, alumina, galvano, and glass ceramic: 20 non precious metal alloy (NP), 20 zirconia (Z), 20 alumina (A), 20 galvano (G), and 20 glass ceramic (GC). Specimens were divided into 2 subgroups. One half of the specimens were applied by Clearfil™ (CR) repair system and, another half of that were applied by Cimara&Cimara(®) Zircon (CZ) repair system. Bonded specimens were stored in 37°C distilled water for 24 h and were thermocycled at 5-55°C for 1,200 cycles with a 30-sec dwell time and 5-sec transfer time. Shear bond strengths were determined with a mechanical testing device. And mode of failure was recorded. Mann Whitney-U and Kruskal Wallis tests were applied to the data at 95% confidence interval level. Infrastructure groups displayed the following values in megapascals: NP = 10.70 ± 1.88; Z = 9.15 ± 0.80; A = 11.65 ± 0.70; GC = 10.95 ± 0.80; and G = 6.88 ± 0.88. The Mann Whitney-U test results showed no significant difference between the repair systems. The Kruskal Wallis test results demonstrated significant difference between the infrastructures. The lowest bond strength values were observed in G group. In conclusion, average bond strength values were in accordance with previously reported values, therefore it can be suggested that intraoral repair of ceramic restorations can be temporary, but a satisfying alternative for patients.
