“…The detailed characteristics of the implants used in the present study were previously reported [ 9 ]. In brief, two-piece implants, consisting of a Ti (Grade 2 ASTM F67) screw as an intrabony portion and a transgingival insert made of Ti (Grade 2 ASTM F67) or zirconia (0.05 wt% Al 2 O 3 -doped 3.0 mol% Y 2 O 3 -stabilized tetragonal zirconia polycrystal, Tosoh, Tokyo, Japan), were fabricated (Sky Blue, Fukuoka, Japan).…”

Currently, along with titanium (Ti), zirconia is widely used as an abutment material for dental implants because it makes it possible to avoid gingival discoloration; however, the epithelial sealing capability of zirconia remains unknown. The purpose of the present study is to elucidate the localization of integrin β4 subunit (Inβ4), one of the main proteins in the attachment structure between gingival junctional epithelial (JE) cells and substrata. Maxillary first molars were extracted from rats, and implants were placed with Ti or zirconia transgingival parts; then, the localization of Inβ4 was observed. Morphological and functional changes in rat oral epithelial cells (OECs) cultured on a culture dish (Dish) and Ti and zirconia plates were also evaluated with Inβ4 immunofluorescence histochemistry and Western blotting. After four weeks of implant placement, the morphology of the peri-implant epithelium (PIE) and the localization of Inβ4 around the Ti and zirconia transgingival parts were similar. However, both exhibited markedly shorter Inβ4-positive bands in the PIE than in the JE around natural teeth. Decreased expression levels of Inβ4 were observed in OECs cultured on Ti and zirconia plates compared with those cultured on Dish. In conclusion, although inferior to natural teeth, zirconia implants are thought to have epithelial sealing properties comparable to those of titanium.

“…[ [387] , [388] , [389] , [390] , [391] , [392] , [393] , [394] , [395] ] Parallel observations were being made from groups investigating implant osseointegration; osseointegration was dependent on implant material, rougher surfaces promoted osseointegration, and adsorbed protein content controlled osseointegration [ [396] , [397] , [398] , [399] , [400] , [401] , [402] ]. Since then, only a handful of studies have confirmed that physicochemistry and topography control HD in vitro [ 403 ] and in rat models [ 384 , [404] , [405] , [406] ], and specifically that HD formation (in rats at least) is generally higher on zirconia than titanium [ [407] , [408] , [409] ]. Overviews of the effects of surface topography on implant soft tissue responses may be found elsewhere [ 347 , [410] , [411] , [412] ].…”

“…Zirconia can be used in patients with titanium allergy and shows it has advantages over titanium for use in oral areas where aesthetics require the use of a material with a color similar to that of natural teeth [ 5 , 6 , 7 ]. In addition, compared to titanium implants, zirconia has excellent biocompatibility and shows a lower adhesion of bacteria, thereby reducing the risk of peri-implantitis [ 8 , 9 , 10 , 11 , 12 ].…”

Plasma treatment on a zirconia surface prevents bacterial contamination and maintains osteoblast activity. To assess the degree of adhesion of Porphyromonas gingivalis on a zirconia surface after non-thermal plasma (NTP) treatment, specimens were treated with plasma for 60, 300, and 600 s, after which P. gingivalis was inoculated onto the surface and incubated for 48 h. To assess osteoblast activity after NTP treatment, osteoblasts (MC3T3-E1) were dispensed onto the specimens contaminated with P. gingivalis immediately after NTP for 60 and 120 s, followed by incubation for 48, 72, and 96 h. P. gingivalis was cultured after 60 s of NTP treatment of zirconia. The NTP and control groups showed no significant difference (p = 0.91), but adhesion was significantly increased following NTP treatment for 300 s or longer (300, 600 s groups) (p < 0.05). After NTP treatment of P. gingivalis-contaminated zirconia, osteoblast activity significantly increased at 72 and 96 h (I60 and I120 s group) in the groups treated with plasma (p < 0.017). Application of NTP to dental zirconia implants for 60 s not only inhibits the proliferation of P. gingivalis, which causes peri-implantitis but also increases osseointegration on zirconia surfaces contaminated with P. gingivalis.
