Umqhele wanyathela noma waphonsa steel: okuyinto engcono?

Kukhethwa okufakelwa namuhla sikhulu ngokwanele, kodwa akuphelele kwamazinyo kukhona imiqhele ethandwa kakhulu yamazinyo ezivumela kukadoti. Zenziwa ngezindlela ezahlukene, ngezinto ezahlukene, futhi ngesinye isikhathi kunzima ukukhetha okukhethwa kukho ezifanele.

Kuyini umqhele futhi ziyini?

Umqhele ibizwa ngokuthi uhlobo non-esikhiphekayo ye Amazinyo okufakelwa enziwe. Ngaphandle-ke iphindwa izinyo ukuma ukufakwa kuba izakhamuzi zaseBosnia zifana emazinyweni enempilo. Isetshenziselwa ekubhujisweni ongaphelele izinyo ukuze kabusha umsebenzi wakhe masticatory futhi ukubukeka yobuhle, kanye ukuyinakekela olwengeziwe. Imiqhele ababonakali ngezikhundla kuncike impahla ekukhiqizeni kwabo. Iza phambi metal, metal-Ceramic, plastic kanye sobumba. Metal ezibhedlela zesimanje kuyaqabukela esetshenziswa, ngoba ukubonakala ebukekayo, futhi asifanele anterior namazinyo sokwenziwa.

Bobumba has a ukubukeka zemvelo. Kuyinto uhlobo eqolo elethwesa imiqhele, zenziwa zirconium oxide. imiqhele Plastic ngokuyinhloko asetshenziswa njengoba lokufakelwa kwezitho yesikhashana ngoba ungenawo wahlala isikhathi eside futhi ukugqoka ukumelana, kalula kuncike umonakalo mechanical behluleka. Yilolu hlobo nengabizi. imiqhele Metal-Ceramic sihlanganise ubuhle namandla, athandwa kakhulu uma ziqhathaniswa nezinye izinhlobo ngenxa yokuthi liyasiza. imiqhele zamazinyo nazo zihlukaniswa indlela yokukhiqiza: umqhele wanyathela bese waphonsa steel.

umqhele isitembu. izimiso yokukhiqiza

Ukukhiqizwa imiqhele wanyathela isineminyaka engaphezu kweyikhulu, bamazinyo abaningi babheka le nqubo esifuze yesikhathi esidlule, kodwa, nokho, zaso zisasebenza kuwo, njengoba kuba impela ezishibhile. Engagqwali cylindrical preform eyenziwe ubukhulu ezahlukene, lapho imishini ekhethekile ngesibhakela sensimbi imiqhele. umkhiqizo okunjalo ubenawo izimfanelo ezithile ukuze ukufakwa yabo efanele futhi ukhululekile egqoke.

Umqhele kufanele uvumelane wanyathela ngokucacile ubukhulu izinyo, uvalwe alisibekele, ngaphandle izikhala kanye voids. Kungenjalo-ke ngeke ukuyithukuthelisa ukuvuvukala izinsini ngenxa lokhu kungaholela yoma. Ukuze lilingane Ukuthokomala kuya okhakhayini izinyo futhi uyivale usebenzisa usimende ekhethekile kwamazinyo. Umqhele akufanele ufake ekujuleni gum, lokho kungase kubangele isifo sezinsini ezifana periodontitis. Ngaphezu kwalokho, kufanele sihambisane ukuma izinyo enempilo, ukuze ukuphazamisa ubuqotho irowu, futhi ube usayizi ezifanele ukuze ugweme ukulimala. Umkhiqizo yakhelwe ukubuyisela izinyo umsebenzi.

Izigaba yokukhiqiza wanyathela metal imiqhele

1. wokuqala owaqhutshelwa Impression emhlathini, wonke ngokuphelele.
2. eminye eyenziwe umkhiqizo oyifunayo
3. irisidi isitembu
4. Wangenza yena umqhele
5. umkhiqizo sihamba wokucwebezelisa ngokugedla
6. umqhele Kuqediwe wagqoka izinyo ekugcobisa fixed usimende.

Izinkomba kanye contraindications ukusetshenziswa imiqhele wanyathela

Isitembu metal imiqhele asetshenziswa:

• ukubhujiswa Akuphelele we izinyo. Kulokhu izinyo ugaye usayizi oyifunayo, iqedwe zonke ukukhubazeka kwakhe kanye izilonda carious ukuvimbela umonakalo.
• Uma titawusungulwa amazinyo okufakelwa, isib, ukuyona, noma amabhuloho. Ukuvikela Amazinyo abutment imiqhele ukukhwezwa.
• Ukubuyisela wabhubhisa ubisi izinyo

Kukhona ezinye contraindications ukusetshenziswa kwabo:

• Bruxism (amazinyo ukugaya, lapho koqweqwe libhujiswa).
• ukubhujiswa okuphelele kwalelizwe izinyo lapho abanalutho ukulondoloza.
• Izifo ezithathelwanayo we ngalo ingaphakathi ngomlomo.

Izinzuzo nezingozi nebubi imiqhele wanyathela

Izinzuzo imiqhele wanyathela:

• ukulungiselela izinyo akudingi isikhathi esiningi bajikela zithathelwa ubuncane, kusukela mncane umqhele izindonga. Lokhu kubalulekile ikakhulukazi uma umkhiqizo ogibele izinyo enempilo, letawuba usekelo lwe Amazinyo okufakelwa enziwe.
• Lena inqubo yezokwelapha elikuvumela ukuba silondoloze amazinyo enempilo futhi ukugwema ukususwa.
• Umqhele wanyathela ingasetshenziswa izimo lapho ezinye izinhlobo zezinsimbi zokuhamba akunakwenzeka (isb, ukusetshenziswa izimila ayikwazi waqaphela ngenxa sikashukela noma ezinye nesineke).
• Kuyinto indlela eshibhile kokwenza sokwenziwa futhi, ngakho-ke, kuba insindiso kubantu abane abathola iholo eliphansi.

Okumbi imiqhele wanyathela:

• Ukusetshenziswa isikhathi eside kuholela nemihuzuko umqhele uphinde uphume yayo kusukela ohlelweni. Ngemva kwalokho, umkhiqizo kufanele zishintshwe entsha.
• Usimende ebamba umqhele, ekugcineni ancibilikisa, okuholela gapping wakhe ukuze izinyo nezinsini. Lokhu, kungabangela ukulimala, ukwakheka caries izinyo ukubhujiswa ngenxa ukungenisa ukudla.
• Uma izinyo libhujiswa ngokuphelele, umqhele kuzosiza ukugcwalisa umsebenzi nut.
• ibhuloho die-cast iqukethe izingxenye eziphothene, okuyinto kunciphisa ukuphila kwebhetri.

umqhele okuqinile

Modern asakazwe indlela bavunyelwe ukukhiqiza eliphezulu umqhele mncane-ngabafaka. ifomu Umqhele ukubunjwa isetshenziswa ukuze alulame izinyo ezilimele, ukuphepha kwayo, njengoba usekelo amabhuloho futhi amazinyo. Yena uphonse ingxubevange ayibe-chromium, ekugcineni kuvela yonke sihloko ngaphandle ukuvuvukala. Ngisho uma udala amabhuloho izakhi nokunamathisela ngomthofu ayidingekile, umklamo uhumusha iyonke. ibhithi Abanjalo bangase embodiments ahlukahlukene akhiqize.

• umqhele ejwayelekile uncoated metal eliphucuziwe.
• Umqhele-kuhlinzwa "igolide." Bangase baxabane nomzimba. Nge nokunwetshiwe egqoke sishaye lisuswe.
• imiqhele plastic okuqinile. Yiba Uhlaka ababunjiwe kanye ikhava plastic for yobuhle namazinyo zemvelo. Lapho emsebenzini noma ngobudedengu kungenzeka egqoke chips plastic.
• Cermet. Uhlobo ezibizayo kakhulu umqhele has ukuqina kanye ukubukeka zemvelo.

Izinkomba ukusetshenziswa cast imiqhele:

• umonakalo Obalulekile emazinyweni.
• Pathology ezimise amazinyo noma indawo yayo.
• Overbite.
• Anomaly usayizi izinyo.
• Ukusekela okufakelwa esikhiphekayo namabhuloho.
• Prevention zemihuzuko yamazinyo, bruxism.

Izinzuzo yabalingisi imiqhele

• Amandla yokukhiqiza lonke hhayi kuphela izingcezu ngabanye, kodwa futhi yokwakha amabhuloho, enikeza amandla ukuqina izihloko.
• Ukuvikeleka. Ukugqoka imiqhele ezinjalo ingahlala iminyaka engu-10, uma izinga impahla kanye ukufakwa zenziwa ezingeni eliphezulu.
• enza Rapid futhi elula.
• Umqhele ukubunjwa wenziwa ngamunye ngezinyo ngasinye bese kufanelana ngokuphelele zingene iqoqo amazinyo ngaphandle kokudala ukungakhululeki ukugqoka.
• Ukunemba umklamo ivumela umqhele obukhulu setha kungekho izikhala ukuthi zivikela amagciwane nokudla ngaphansi kwaso.
• Ukuze anterior namazinyo imiqhele kungenziwa ekhiqizwa nge sishaye noma ambozwe sokuvela yobuhle. Umqhele wanyathela kwakungenzeka lokhu alinikezi.

Okumbi cast imiqhele

• Ekulungiseleleni ukufakwa umqhele igedle ungqimba kunalokho enkulu izinyo enempilo.
• Ekubunjweni Imiqhele kufanele kube eqondile kakhulu, kungenjalo ukufakwa futhi egqoke kuyoba yinkinga.
• Lapho ethola kushisa noma kubanda ukudla kungenzeka ukungakhululeki ngenxa okusezingeni eliphezulu conductivity impahla ezishisayo.
• Intengo yale mikhiqizo iphakeme kakhulu kunanoma Imiqhele isitembu.
