Zirconia

Metal-zvedongo korona zvinoshandiswa mazino tsika kwenguva yakareba uye zvikuru zvinobudirira. Vane yakasimba, asi vane zvimwe zvainovhiringidzawo maererano nechitarisiko. mhenyu zino zvazviri akasikwa chete zvishomanana, sokunge ukasachenjerera sarudza mavara Ceramics. Izvi imhaka yokuti simbi kuumbwa ine ruvara rwaro, chifukidzo zvizere kuti hakuwanzoshandi. Chimwe zvakaipira prostheses izvi - kunaka simbi migumisiro pamusoro matadza. Ceramic korona havana zvainovhiringidzawo izvi, asi havasi zvinenge simba korona resimbi puranga.

In dentistry ano, kusarudzwa zvinhu nokuda prosthesis kufungwa kwete chete kwayo functionality, asiwo aesthetics. Zirconia, iro rakashandiswa prosthetics mu okurapa kubva 1969, vari kuramba kushandiswa nokuda kwezvifananidzo zvaAtemisi mazino prostheses. Dzimwe nguva, pasina kushandisa makemikari zita rake chairo, zvinhu izvi anongonzi zirconium. In dentistry, kakawanda kushandiswa pakugadzira mutumbi mazino korona.

Nekorona zirconium dioxide, anokwanisa wokushandura chiedza, rakafanana translucency dzinongoitika mazino, saka tsvaka dzinongoitika uye havasi zvakasiyana dzinongoitika mazino. Muchiitiko ichi vaine mukurumari akafanana simba korona zvesimbi.

In anogadzira zvinhu denture umbowo korona kazhinji vainyungudutsa. Korona zirconia - anosara. A Laser scanner vagara vandifungira pezvakaita korona yemberi, humboo chinogadzirwa ne purogiramu yekombiyuta, uye kombiyuta muenzaniso mazano rekorona. Zvadaro rinokosha midziyo, maererano purogiramu yepakombiyuta akafanorongerwa akaurayiwa achicheka kubva chete chimedu zirconia. The zvichiguma korona haana chete yakakwirira nemazvo asiwo kunovimbisa akakwana chitarisiko.

Munguva ichangopfuura, korona yacho zvedongo zvinhu chete yakaiswa mberi mazino, kureva kwavo kushandisa zvakanga zvakafanira, asi, aesthetic zvikonzero pane kushanda. Kushandisa zirconia haana painogumira. Zvakakodzera kuti prosthetic Anterior uye posterior meno, uye blends zvakakwana chete anodyara. Achishandisa ruzivo urwu, kugadzirwa nekorona kuroorwa uye kuwedzerwa mabhiriji. Zirconia - hypoallergenic uye zvachose bioinert pachinhu mumuviri womunhu zvinhu anogona saka kushandiswa prosthetics kunyange asingatani neutachiona wevarwere. Maererano dhigirii Bioinert inodarika kunyange ndarama.

Zirconia ane yakakwirira kumbogadzirwa kuti mudziye ehupfumi, saka korona kudzivirira mazino kubva tembiricha akanyanyisa. Uyu Boon vaya varwere meno tisanzwe inopisa uye kutonhora chikafu.

Chitunha korona chitete chaizvo, Ukobvu ndiyo 0,4 chete mm. Naizvozvo, nenyama yose denture mamiriro rinopa zvachose nguva imwe muropa "mazino itsva." Kunze pepuranga rakagadzirwa zirconia kusiyana simbi hakuiti deform pamwe nguva. Nokuti veneering Ceramic inoshandiswa, rakagadzirirwa zvakananga kuti chinangwa ichi uye vane translucency zvakafanana.

Vanhu vakawanda vanoziva kunzwa kutya kukuvadza ari zino korona pa chikafu zvakare zvikukutu raskusyvanii. zirconia achaita kubvisa zvose kufunganya ichi. Kana paine hairline mitswi, mashoko anonaya nechivako wayo chete panguva samolecular chechetere.

Kana iri mazino prosthesis sezvo simbi kana simbi-zvedongo korona, ari matadza kazhinji anooneka dema bezel. Mazino pamwe zirconia marangwanda, kunyange kushandiswa nguva refu, haakonzeri chero kuchinja matadza.
