Characterization of Wet Powder-Sprayed Zirconia/Calcium Phosphate Coating for Dental Implants

Abstract: The present study revealed a higher stability and firm adhesion of the mixed coating compared with a pure calcium phosphate coating. We also successfully demonstrate the particular versatility of the WPS technique for dental implants by coating a complex curved surface.

“…Airbrush spraying of ceramic slurries is a versatile method that allows the coating of substrates having complex shape with an adequate control of coating thickness [17][18][19][20]; however, there is a paucity of studies about its use in the field of bioceramics. Very recently, Pardun et al reported the characterization of wet nanopowder-sprayed zirconia/HA composite coatings on dental implants (screws) [21]. To the best of the authors' knowledge, the use of airbrush spraying on orthopaedic implants has been never documented and, accordingly, the present article represents a pilot study.…”

“…Airbrush spraying of ceramic slurries is a versatile strategy to produce coatings with good control of the thickness [17][18][19][20] and promising possibilities of scaling up from the "Lab scale" to industrial production. However, there is a relative paucity of studies concerning the layer-wise deposition of ceramic slurries for biomedical applications [21,22] and the full potentialities of this approach are still unexplored. We also developed a mechanical model based on the concepts of quantized fracture mechanics (QFM) [23] to describe the bonding strength of the glass-ceramic coating to the alumina substrate.…”

“…The coatings were applied with the WPS technique, which suitability was already shown in previous works. 19,31 Since bone is a porous material, the obtained porous coatings represent a more natural morphology with varying pore sizes in order to facilitate cell anchoring and thus bone ingrowth. Moreover, Mg-addition was considered to increase the coating biocompatibility due to a more similar bone composition.…”

“…This is supported by the comparison of the B3B results of specimens with Mg-containing coatings and the reference sample TZCP. Despite the presence of monoclinic and cubic zirconia in the coating 19 TZCP exhibits a good and with uncoated TZ comparable mechanical strength since no interface layer between coating and substrate was formed. Therefore, it can be hypothesized that the coating phase composition has only a negligible influence on the strength without the existence of an interface layer.…”
