“…The methods necessary for creating strong adhesion to a zirconia surface are a matter of controversy. However, some previous studies reported that MZR retention depends on mechanical roughening of the inner surface and chemical treatments with adhesive monomer in primers for zirconia (21,28). Primers or adhesives containing MDP after low-pressure sandblasting are an excellent option for bonding to zirconia (37)(38)(39).…”

“…However, several concerns remain regarding preparation design, wear resistance and antagonist wear, bonding effectiveness, and the inherent opaque color of the material. Recent in vitro studies of the basic properties and clinical performance of zirconia restorations yielded promising findings (17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28). Although several clinical reports have highlighted the effectiveness of MZRs, including single restorations and fixed partial dentures for teeth and implants (29)(30)(31), few studies have investigated the outcomes of MZRs.…”

Retrospective clinical evaluation of posterior monolithic zirconia restorations after 1 to 3.5 years of clinical service

This retrospective study analyzed clinical outcomes of monolithic zirconia restorations (MZRs) and factors related to restoration success. Patient records were searched to identify those provided MZRs (Cercon ht) for premolars or molars between April 2012 and March 2016. All MZRs were placed according to a standardized protocol. Kaplan-Meier analysis was used to assess MZR performance and failure after recall appointments at 1 year or later. In total, 101 patients received 148 MZRs. Mean duration of follow-up was 25.0 ± 9.9 months. Six MZRs required replacement: three because of pulpal complications, one because of root fracture of an abutment tooth, one because of restoration fracture, and one because the tooth was used as an abutment tooth for a fixed partial denture after root fracture of an adjacent tooth. The cumulative MZR survival (success) rate at 3.5 years was 91.5% (95% confidence interval, 82.1% to 100%). The findings of this short-term retrospective study indicate that posterior MZRs are a therapeutic option for certain patients. In addition, several clinical procedures contribute to MZR success, including preparation design and occlusal and adhesive surface treatments.

Creating an alkaline environment prior to 10-methacryloyloxydecyldihydrogenphosphate (MDP) conditioning improves the resin bonding of zirconia. The present study evaluated the effects of four alkaline coatings with different water solubilities and pH values on resin bonding of MDP-conditioned zirconia. Two alkaline nanoparticle coatings were studied in particular. Thermodynamics calculations were performed to evaluate the strengths of MDP-tetragonal phase zirconia chemical bonds at different pH values. Zirconia surfaces with and without alkaline coatings were characterized by scanning electron microscope (SEM)/energy dispersive spectrometer and Fourier transform infrared spectroscopy; alkaline coatings included NaOH, Ca(OH) 2 , nano-MgO, and nano-Zr(OH) 4 . A shear bond strength (SBS) test was performed to evaluate the effects of the four alkaline coatings on bonding; the alkaline coatings were applied to the surfaces prior to conditioning the zirconia with MDP-containing primers. Gibbs free energies of the MDP-tetragonal zirconia crystal model coordination reaction in different pH environments were −583.892 (NaOH), −569.048 [Ca(OH) 2 ], −547.393 (MgO), and −530.279 kJ/mol [Zr(OH) 4 ]. Thermodynamic calculations indicated that the alkaline coatings improved bonding in the following order: NaOH > Ca(OH) 2 > MgO > Zr(OH) 4 . Statistical analysis of SBS tests showed a different result. SBSs were significantly different in groups that had different alkaline coatings, but it was not influenced by different primers. All four alkaline coatings increased SBS compared to control groups. Of the four coatings, nano-Zr(OH) 4 and -MgO showed higher SBS. Therefore, preparing nano-Zr(OH) 4 or -MgO coatings prior to conditioning with MDP-containing primers may potentially improve resin bonding of zirconia in the clinic.

“…The physical properties of resin luting cements have been improved using nano-sized fillers and modifying the resin matrix formulation (19). The versatility of universal adhesive systems and improved mechanical properties of the resin luting cement offer a new and simplified approach to bonding ceramic restorations to teeth (20,21). Since the recent development of resin luting cements for universal adhesive systems, little information is currently available about their wear properties.…”

Simulated localized wear of resin luting cements for universal adhesive systems with different curing mode

et al. 2018

View full text Add to dashboard Cite

This study evaluated the simulated localized wear of resin luting cements for universal adhesive systems using different curing modes. Five resin luting cements for universal adhesive systems were evaluated and subsequently subjected to wear challenge in a Leinfelder-Suzuki wear simulation device. Overall, 20 specimens from each resin luting cement were photo-cured for 40 s (dual-cure group), and 20 specimens of each material were not photocured (chemical-cure group). Simulated localized wear was generated using a stainless steel ball-bearing antagonist in water slurry of polymethylmethacrylate beads. In addition, scanning electron microscopy (SEM) observations of resin luting cements and wear facets were conducted. Significant differences in simulated wear and SEM observations of wear facets were evident among the materials in the dual-and chemical-cure groups. The simulated wear and SEM observations of wear facets of G-CEM LinkForce and Panavia V5 were not influenced by the curing mode.SEM observations of resin luting cements were material dependent. In most cases, dual curing appears to ensure greater wear resistance of resin luting cements than chemical curing alone. The wear resistance of some resin luting cements appears to be material dependent and is not influenced by the curing mode.
