Abstract:It is generally accepted that a micrometer scale roughness supports the osseointegration of titanium implants. While abrasive technologies can easily be employed to create a micro-topography on titanium surfaces, the preparation of rough ceramic surfaces is more challenging. Typically, abrasive treatments of yttriastabilized tetragonal zirconia polycrystal (Y-TZP) surfaces result in rather smooth topographies (R a < 0.6 μm). Furthermore, when this sandblasting process is performed after firing, a transformation of the tetragonal into the monoclinic phase is observed. Exceeding phase transformation may lead to a decreased flexural strength and an increased brittleness -two highly undesirable processes for a ceramic for load bearing applications. In the present study Y-TZP surfaces were sandblasted between the presintering and the final sintering step. Instead of corundum particles, sintered Y-TZP grit was employed for blasting. By varying the particle size and the sandblasting pressure, moderately rough (R a ~ 1.7 μm) and rough (R a ~ 3 μm) Y-TZP surfaces could be prepared. The resulting rough Y-TZP materials were analyzed with respect to their microstructure, flexural strength and 3D surface topography. The results of the subsequent in vitro and in vivo experiments reveal a cytocompatibility and a bone-implant contact that is well comparable to the reference material titanium SLA (sandblasted, large grit, acid etched).

“…Zirconia enjoys popularity in the dental community due to its bright coloring, and is recommended in cases where the quantity of soft tissue would not be enough to mask the gray color of Ti, especially in areas of esthetic concern 6) . Futhermore, zirconia was found to be as biocompatible as Ti 7,8) .…”

Initial attachment of human oral keratinocytes (HOKs) cultured on mirror-surfaced commercially pure titanium (Ti) or yttriastabilized tetragonal zirconia polycrystals (TZP) was investigated. Numbers of viable attached HOKs, their mRNAs and proteins expression of laminin γ2 and integrin β4 were evaluated using the WST-1 assay, quantitative real-time PCR and enzyme-linked immunosorbent assay, respectively. Localization of laminin γ2 and integrin β4 was observed using immunofluorescent staining. Cell spreading was evaluated by measuring the perimeter of actin on fluorescent stained images, and cell morphology was examined using scanning electron microscopy. At 1 h TZP elicited less of initial attachment than Ti in terms of mRNAs expression and proteins expression of laminin γ2 and integrin β4 (p<0.05). However, at 48 h TZP was showed similar initial attachment in comparison to Ti. Therefore, it was suggested that TZP has a potential to form epithelial attachment like Ti.

Loaded Custom‐Made Zirconia and Titanium Implants Show Similar Osseointegration: An Animal Experiment

Abstract: Within the limits of this animal experiment, it can be concluded that the custom-made zirconia implants osseointegrated to the same extent as custom-made titanium control implants and show the same peri-implant soft tissue dimensions.
