Zirconium oxide: Properties, contraindications ikakhulukazi ukusebenzisa amazinyo

Zirconium oxide is eside kakhulu isetshenzisiwe amazinyo, futhi lubonakala ngokuqina ukuqina yayo futhi ukuhambisana ne imvelo. Konke lokhu kuqinisekiswa izifundo zokwelapha eziningi.

Izinzuzo nezidumbu

Zirconium oxide isetshenziswa ukudala imiklamo eminingi kanye, ikakhulukazi, izinhlaka kwezindlu kusekelwe kuyo une-ukunemba emangalisayo. Konke lokhu kwenziwa ngokusebenzisa ubuchwepheshe yezokwelapha zesimanje. Imikhiqizo esekelwe le nto okuhlala, ngokusobala akekho ukuhlukanisa umkhiqizo yokufakelwa amazinyo zemvelo.

Zirconium oxide uphahlwe a zobumba mass ekhethekile, okuyinto has a odabuka yemvelo. Konke lokhu kwenza umkhiqizo ophelele njengoba kuqhathaniswa ezivamile izakhiwo metal-Ceramic esetshenziswa wodokotela bamazinyo.

Ithebhu zirconium oxide, veneers namabhuloho - ziyaziswa njengamalungu izinto okuhlala kanye biocompatible.

A Uhlaka namanje ngesisekelo le nto uyakwazi ukwehlisa odongeni ukujiya elethwesa imiqhele, ngokulandelana, we machining kanzima izicubu amazinyo ukujula nayo iyancishiswa. Ngenxa yalesi ukwesekwa emlonyeni kungaba basindiswe, futhi sokwenziwa ukuze kube lula.

Izici zonke-Ceramic

Zirconium oxide isetshenziswa ukudala imiqhele, lapho aluminium sengezwe. Zibizwa ngokuthi nangokuthi metal-mahhala. Ngalezi zitho namuhla lalivamile futhi zinezikhathi amandla zabo eziphakemeyo. sici yabo eyinhloko - ukungabi khona izingxenye zensimbi okusezingeni eliphezulu design yobuhle.

Metal-free umqhele zirconia futhi alumina kuwumphumela ukwethulwa ubuchwepheshe okusezingeni eliphezulu yesimanje ukuze amazinyo. Akukhona nje kuphela, eliqinile, biocompatible emazinyweni, kodwa futhi ukukhanya esobala. Ngaphandle, akekho umuntu ucabanga ukuthi lokhu kuphela umqhele, ngakho-ke ubukeka zemvelo.

Dala imiqhele non-metal

zobumba ezinjalo kusetshenziswa kakhulu ekukhiqizeni hhayi kuphela wonke umqhele, kodwa futhi inlays futhi veneers. Uma lwezimpawu ezifakwe mnyama noma umqhele ubudala umbala, zirconium oxide elisemandleni enkabeni yalo, kuyosisiza ukuba uthuthukise.

Ngo womshini udokotela isidumbu kususa ukhonkolo we dentition isiguli, bese wenza imodeli wax kwezindlu kusekelwe kuyo. It is ukuskenwa futhi agcinwe kwikhompyutha ke ukudala ifomu ngakuthathu ahlelelwe ukuhlangabezana ukuncipha esizayo. Khona-ke uzimele ibekwa idivayisi Milling ekhethekile lapho nepepper zirconium oxide.

It is ke sintered e esithandweni design, ezuza amandla. Futhi ekugcineni, uzimele uphahlwe mass sobumba. Umphumela etholwe biocompatible imiqhele amazinyo, zirconium oxide kule sici kubalulekile.

mbumbulu

Lokufakelwa kwezitho we zirconium oxide ezimweni eziningi kahle ziqondakala umzimba womuntu. Ziyakwazi okuhlala kanye enokwethenjelwa, akukho ingozi kwenqatshwa futhi ukutheleleka.

Mbumbulu namazinyo zemvelo abayifunayo kuleso oxide zirconium kwakwakhe has a luhlaza nomhlophe. Uma ufaka umqhele metal-Ceramic ezinjalo ngeke kutholakale ngoba design ifremu kuyodingeka umbala metallic. A sensimbi Ceramic alibonisi ngokusebenzisa, imiqhele eline-enamathela ekhethekile. Ngenxa yalokho, la lokufakelwa kwezitho musa ukudlulisa ukukhanya, nombala ukujula abanalo. Izinsini akukukhanyiselanga kusuka ngaphakathi, njengoba ifomu zemvelo, futhi khona nomzimba angaphandle emlonyeni iba sobala.

Buhle othomathikhi yokukhiqiza Imodi

Imiqhele ngaphezulu ukuthi metal-mahhala zenziwa ngobuchwepheshe ekhethekile, okuyinto kuhluke ngokuphelele imikhiqizo ezenziwe ngesandla sensimbi. Zonke izinqubo abazenzi kwimodi okuzenzakalelayo.

Ukubekezelelana igebe phakathi sokwenziwa kanye izinyo ngokwayo kungaba isukela microns 100 kuya ku-300. Ngokusebenzisa ubuchwepheshe bamuva, isetshenziselwe ukudala imikhiqizo eyenziwe zirconia, ke lancipha 30 microns. Lokhu kusho ngokunemba esiphezulu emalungeni phakathi kwamazinyo aso kanye zokuhamba.

Ukwenza amabhuloho

Ngisho ifomu enjalo ethile sokwenziwa kungenziwa ekhiqizwa ngaphandle uhlaka lwensimbi. Ibhuloho of zirconium oxide kungabuye ukusebenzisa, kodwa ngeke akwazi ukuba obuphelele ezinkulu, njengenjwayelo. nangesimo sakhe, ngokungafani metal, kuyoba sobala.

Futhi, zirconium oxide ingasetshenziswa ngesikhathi sokwenziwa ephathelene nokufakelwa, uma kudingeka ukuba isiguli sibe ezingeni lelisetulu sobuhle bayo. Futhi, njengoba kushiwo ngaphambili, bangaqashwa womshini yiluphi uhlobo sokwenziwa.

Ingaphandle

Omunye izinzuzo ukhiye imiqhele esekelwe zirconium oxide kuyinto ukubukeka zemvelo futhi likhange kakhulu. Uma nokubuyiselwa metal-Ceramic zihlale luhlaza ehlukile, kulesi simo kungenzeka eyolanda ezingeni Uhlaka akwazi ngokugcwele umbala wamazinyo lesiguli. Kungakhathaliseki uhlobo ukukhanyisa, izinyo izohlala sobala. Ngaphezu kwalokho, ngokungafani sensimbi, okuyinto nge isikhathi bathambekele mnyama futhi babe sikhubazekile, zirconium oxide, ngisho iminyaka eminingi kuyinto efanayo.

Futhi, eziningi ngokuvamile akhononde ushintsho umbala izinsini eduze imiqhele metal-Ceramic. Lokhu kwenzeka ngenxa yokuthi umklamo ifreyimu inomphumela omubi phezu izicubu eduze nalo. Yiqiniso, izinsini redden noma babe cyanosis ngaso sonke isikhathi, kodwa ngokuvamile lokho kwanele. Lokufakelwa kwezitho nge zirconia aluqede ngokuphelele lesi simanga.

ukuhambisana

Zirconium oxide muhle ngoba izakhiwo hypoallergenic. Ngaphambi le nto lalisetshenziswa amazinyo, ngokuvamile asetshenziswe ekukhiqizeni amanye amakhanda ngoba hip lokufakelwa kwezitho ukuthuthukisa amandla abo.

ukubonakaliswa nomzimba iziguli phakathi nokufaka amazinyo yokufakelwa noma amathebhu ngokuvamile zenzeka njalo ngokwanele. Ngaphezu kwalokho, lezi ukusabela ungaboniswa ngisho nalapho esebenzisa yizicukuthwane zinhlobo metal (igolide, i-platinum, palladium, nabanye). Imiqhele noma zirconium oxide amabhuloho ngoba abantu abaningi abaphethwe komzimba bawukuphela Isixazululo ukuze alethe amazinyo.

inkinga ezinyweni ukuzwela futhi ngokuvamile. Phakathi mkhuba wokufakelwa kungavimbela ufake konke okudingayo. Ngakho, uma ufaka imiqhele ngaphandle embundwini metal siyahluka kakhulu ube umuntu ongcono. Konke lokhu kungenxa yokuthi oxide zirconium kuyinto enhle kakhulu yisivikelo yemvelo kanye ongavikela namazinyo kusuka amazinga eqile okushisa nokubanda izinkomba. Uma kusekelwe kuyo ukukhiqiza copings, isiguli ngeke wadalula ukushukuma ezishisayo.

Izinzuzo Umphumela impahla

Zirconium oxide kancane ahlanganiswe aluminium futhi sisimamiswe ngenxa yttrium, kamuva kwenza imikhiqizo yayo ngesisekelo eqinile futhi ukukhanya. Ngaphezu kwalokho, ukubukeka microcracks phezu, isakhiwo ebusweni ubuyisela ngokwako on ezingeni yamangqamuzana ezinto eziphilayo.

Imiqhele zakhiwe zirconium, hhayi kuphela amazinyo angaphambili, kodwa futhi eceleni.

Lokhu kwaziswa, phakathi kwezinye izinto, ubhekwa ekahle kakhulu ukulungisa ukuphakama bite. Akanalo porosity, ngokungafani metal zobumba, ngakho nemihuzuko abamelene anezinga aphansi.

Futhi iqiniso lokuthi Imiqhele yokwakheka kungaba sidalule yokugaya, ivumela ochwepheshe ezikhethekile ngempumelelo uzisebenzise ngesikhathi sokwenziwa by counter ibhithi ukuthi ubambe ukuphakama bite.

Icubungula izicubu kanzima kwamazinyo uma efakwe sokwenziwa wonke-Ceramic incane. Frame zamazinyo zirconium oxide has a ukushuba 0.4 kwangu. Lokhu kuvumela ubuncane ugaye kubo ngisho wenze sokwenziwa eziphilayo.

Okumbi kanye contraindications

Njenganoma yimuphi omunye umkhiqizo lisetshenziswe ngenhloso yamazinyo okusekelwe zirconium oxide lokufakelwa kwezitho babe Izimo zabo. Nakuba kulesi simo kukhona mabili kuphela, okuyinto musa Kuvame kakhulu:

• bruxism;
• overbite libizwa.

Kwezinye izimo, ungase ukwazi ukufaka imiqhele, ngisho uma isiguli kuletha isitifiketi sokuba khona ngesikhathi umzimba wakho uxabana ne izingxenye ezithile lokufakelwa kwezitho. Ukuze zonke-Ceramic ngeke ngayo.

Ngokuqondene nemibi imikhiqizo esekelwe zirconium oxide, empeleni babe. Nokho, ukhiye futhi nguye kuphela - kuyinto izindleko zabo eziphakeme. Leli intengo akuyona kuphela ukusetshenziswa izingxenye ezithile, kodwa futhi yinkimbinkimbi womshini imiqhele. Lapha, uchwepheshe kumele ibe nezinga eliphezulu amakhono futhi bafundiswe isu elikhethekile ezingeni eliphezulu.

Uma isiguli ayinayo imali somkhiqizo ezibizayo esekelwe zirconium oxide, kwakuyodingeka ube ukunikela version yakhe yesabelomali ngesisekelo ukucutshungulwa ingilazi. Imiqhele, zazo uhlaliseke nge-nitrous yttrium, ibiza kakhulu.

Njengoba ubona, ngentuthuko zanamuhla emkhakheni amazinyo kungaba ngokuphawulekayo ngcono izimpilo zalabo abadinga amazinyo futhi akwazi ukubekezelela kubo.
