“…20,21 Nevertheless, zirconia has some limitations linked to its high elastic modulus (at about 240-260 GPa), hardness (at about 1.2 GPa), and ultralow chemical reactivity. The elastic modulus of zirconia is significantly higher than that recorded on cortical bone (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) GPa) that can result in stress shielding and peri-implant bone loss. The high hardness and chemical resistance is a limitation for surface modification procedure involving conventional grit-blasting and etching procedures.…”

“…[13][14][15][16] The main benefits of zirconia compared to titanium implants include no metal aura in cases of deficiency of the buccal bone wall and/or thin mucosal biotype, corrosion resistance, and hypoallergenicity. 17,18 The color of zirconia can vary depending on the oxide content to mimic the color of natural teeth, which is a significant advantage to overcome aesthetic issues of titanium-based implant systems. 19 Additionally, zirconia is a biologically inert material possessing high biocompatibility that can provide osseointegration.…”

Custom‐made root‐analogue zirconia implants: A scoping review on mechanical and biological benefits

The aim of this study was to conduct a literature review on the potential benefits of custom-made root-analogue zirconia implants. A PubMed and ScienceDirect bibliographical search was carried out from 1969 to 2017. The increased interest in zirconia-based dental structures linked to aesthetic and biological outcomes have been reported in literature. Recent technological advances have focused on novel strategies for modification of zirconia-based surfaces to accelerate osseointegration. However, only a few studies revealed mechanical and biological benefits of custom-made root-analogue zirconia implants and therefore further studies should investigate the influence of different design and surface modification on the performance of such implants. Custom-made root-analogue zirconia implants have become a viable alternative to overcome limitations concerning stress distribution, aesthetics, and peri-implantitis induced by biofilms. However, further in vitro and in vivo studies on surface-bone interactions and mechanical behavior of zirconia should be evaluated to reduce clinical issues regarding mechanical failures and late peri-implant bone loss. © 2018 Wiley Periodicals, Inc.

Although yttria‐stabilized tetragonal zirconia polycrystals (Y‐TZP) ceramics have been widely used as restorative materials due to their high mechanical strength, unique esthetic effect, and good biocompatibility, their general application to implant materials is still limited by their biological inertness and hydrothermal aging phenomenon. Existing studies have attempted to investigate how to enhance the bioactivity or hydrothermal aging resistance of Y‐TZP. Still, more studies need to be done on the modification that combines these two aspects. In this study, Y‐TZP was prepared by 77S bioactive glass (BG) sol and akermanite (AKT) sol infiltration and microwave sintering, which provided Y‐TZP with high bioactivity while maintaining resistance to hydrothermal aging. Results of phase composition evaluation, microstructural characteristics, and mechanical property tests showed that modified Y‐TZP specimens exhibited little or no tetragonal‐to‐monoclinic (t → m) transformation and maintained relatively high mechanical properties after accelerated hydrothermal aging treatment. The in vitro biological behaviors showed that the introduction of 77S BG and AKT significantly promoted cell adhesion, spreading, viability, and proliferation on the surface of modified Y‐TZP ceramics. Therefore, this modification could effectively enhance the bioactivity and hydrothermal aging resistance of Y‐TZP ceramics for its application in dental implant materials.
