Umqhele ukubunjwa: ukushuba we isithombe, izigaba womshini

Izingxenye ohlangothini ngalo ingaphakathi ngomlomo ngokuvamile efakwe umqhele waphonsa steel. Lokhu kuyadingeka ukuze ubuyisele ubuqotho yokwakheka dentition, lapho ngenxa yezizathu ezihlukahlukene umuntu ulahlekelwa eyodwa noma ngaphezulu amazinyo. Lolu hlobo sokwenziwa umsebenzi ikuvumela ukuba ugcine apharathasi emhlathini.

Yini izinto zenziwa umqhele

Ukuze kukhiqizwe imiqhele usebenzisa Alloys integrally inkatho ngazo ifa amandla aphezulu. Ngo ngezinto zokwakha zesimanje amazinyo esetshenziswa chromium-based, eminye elixutshiwe ne-nickel, ayibe. Kahle kungase kutholakale ukusetshenziswa titanium. Lokhu metal has a ukumelana abezindaba nolaka, awusebenzi mnyama ukuze okufanayo has biocompatibility okusezingeni eliphezulu. Umqhele ukubunjwa kungenziwa yakhiwe namatshe ayigugu. imiqhele yegolide uvumele ukwenza kufanelekile ngqo kakhulu, ngoba metal has a ductility okusezingeni eliphezulu. Ziyakwazi ezinhle ukusebenzisa, akuvamile ziwohloke. Nokho, umqhele wegolide ezigugile okwamanje, ngaphezu, has a izindleko eliphezulu. I izinkomba esiyinhloko imiqhele wokufakelwa iraba okuqinile kuyinto ukulahlekelwa ingqikithi eyodwa noma ngaphezulu amazinyo, ekubuyiseleni dentition ukusebenza.

Izinhlobo ezinkulu yonke-ucezu amazinyo okufakelwa

Kuze kube manje, ukwaba izinhlobo ezinjalo cast imiqhele:

• lokufakelwa kwezitho Uncoated - isimo kwensimbi umzali, iphucuziwe ukuze kukhanye.
• Umqhele ukubunjwa powder-camera (ikakhulukazi igolide). Lolu hlobo has ethile - sishaye has Kusizuzisa hhayi ngokuphelele mucosa ngomlomo.
• Uhlobo lwesithathu - umqhele ne ulwelwesi. Njengoba lisetshenziswe plastic impahla isigubungelo noma cermet. laths Special camera kobuso sokwenziwa endaweni ukumamatheka. Naphezu ukubukeka ezinhle tebuciko, izembozo enjalo angagunda. Ngaphezu kwalokho, izindleko yabo kakhulu anda ngenxa ukusetshenziswa kwezinto eziphinde zisebenziseke ezibizayo.

Eyokuqala izinhlobo ezimbili zisetshenziselwa esikhundleni namazinyo posterior. Uma udinga amazinyo okufakelwa phambi dentition, kungcono ukuya ukubukeka lwesithathu. Kufanele kuqashelwe ukuthi udonga umqhele ngempela nomzimba omncane (1 mm). Lokhu kakhulu kuthinta pre-sawdust eziphilayo izinyo.

Ukukhiqizwa cast imiqhele. Izigaba emitholampilo laboratory lokuqala

Okokuqala, udokotela wamazinyo ubophekile ukuba ahlole ngalo ingaphakathi ngomlomo. Uma une endaweni ethintekile, kumele sanitized. Isinyathelo sokuqala sihilela ukulungiswa umbono emitholampilo ye dentition kanye izinyo ngokwayo ukuze asakazwe wayo. Ukuze wenze lokhu ngokuvamile zisebenzisa ekhethekile abicah impahla ezingasetshenziswa ukubonisa ngokugcwele zonke izici yokwakheka. Phakathi nale nkathi, isiguli kungenzeka ukuthi abeke design akhethekile esikhashana. Umsebenti wabo - ukusheshisa gum umlutha ukudala umphumela yobuhle. Ngesikhathi esigabeni sokuqala lab kwenza dismountable imodeli usimende. Ngaphezu kwalokho kukhona occluder wokufakelwa ku Gypsum abalingisa wax umqhele. Ngemva kwalokho, wax esikhundleni zensimbi (eliphonswayo Laboratories ekhethekile). Khona-ke steel cast umqhele iphathwe kahle kahle.

Eyesibili esiteji lwasemtholampilo futhi laboratory

Ngesikhathi esigabeni sesibili (zokwelapha) kwenzeka fit kuyinto umkhiqizo. Ngaphezu kwalokho ekhiqizwa ethi awafike kude izinyo imiqhele ukufakwa izinga. I sokwenziwa ligcwele wax sisetshenziswa kusayithi ukufakwa. impahla okweqile akube kusakhulunywa ngembobo pre-yamba. Khona-ke umqhele isuswe, esehlelembe iyiphi ukungalungi, ihlolwe ubuhlobo occlusal. Umkhiqizo ukulungele ithunyelwa elabhorethri. Uveza wokucwebezelisa, ukugaya. ngokunemba yokukhiqiza bahlolelwa umfuziselo owenziwe ngosimende. Kubalulekile futhi ukuhlola nendlela ihlanganyela sokwenziwa nge parallel namazinyo-abantu abamelene nani. Kuyaphawuleka ukuthi umsebenzi lidinga okuhlushwa. Ngisho iphutha elincane phakathi ubukhulu kungabangela izinkinga lapho efake umqhele, ubuhlungu njalo kanye nokuhlukumezeka.

ukubekwa Final

Umqhele siphelile iqinile ku ngalo ingaphakathi ngomlomo. Kulokhu, ekupheleni sokwenziwa by ekushoniseni ushingamu kufanele kube omncane. ukufakwa izinga iyenziwa futhi kanjani uvalwe imbozwe izinyo lesiguli. Futhi, kufanele kube khona ukungakhululeki ngesikhathi sokuvalwa abantu abamelene nani. Uma kudingeka, kungase kudingeke ethi awafike kude ingxenye impahla. Futhi, nokushoda umqhele okubalulekile kungenzeka kabusha ithunyelwa elabhorethri. Uma imilenze abantu efanelekayo ke akabi nawo umuzwa wokuthi kukhona nenkanuko edlulele unomphela usimende. Kufanele kuqashelwe, uma imiqhele yokusetha yabalingisi, ekukhiqizeni ngamanani amancane izinyathelo uzithatha Adalberto isikhathi eside - amasonto amaningana.

Izinzuzo main yalezi imiqhele

Okokuqala-cast imiqhele abe nokuphila isikhathi eside. Njengoba lokhu ubuchwepheshe ikuvumela ukuba sibonise ngokugcwele yonke imininingwane isakhiwo yokwakheka, amazinyo okufakelwa ukulingana kahle i-dentition, ngabo udle ukudla nokunye .. Konke lokhu kwenza kube nokwenzeka sizigqoke iminyaka engaphezu kwengu-10. Ngo womshini amabhuloho asisebenzi nokunamathisela ngomthofu, elibuye kuqinisa umqhele, ngelula ukuphila kwabo. Enye inzuzo - umqhele iqhubeka isikhathi esingaphezu izicubu yamazinyo (ngokungafani cermets). Njengoba ukushuba we umqhele yabalingisi akuyona ezingaphezu kuka 0.3-1 mm, izinyo okungenani amenable ukuba ukugaywa. Ngenxa yalokho, ukuphila kwakhe enwetshiwe. Ngaphezu kwalokho, lezi lokufakelwa kwezitho kulula akhiqize. Futhi-ke, waphonsa steel umqhele (isithombe ngezansi) kuyinto itholakale kalula, izindleko zayo kuqhathaniswa ongaphakeme.

Okumbi-cast izakhiwo

Yiqiniso, lezi imiqhele ayifanele amazinyo angaphambili. Ububanzi ubuncane imibala - segolide, isiliva - lokhu ingenye bokwenza ezinkulu zalolu sokwenziwa. Metal has a conductivity ezinkulu ezishisayo, lokho kungase kubangele emizweni ezingemnandi ku ngalo ingaphakathi ngomlomo isiguli. Njengoba lisetshenziswe womshini carbides waqinisa, imiqhele kungaba avuse ukuguga, ukusonteka sokumelana emhlathini dentition. Ngaphezu kwalokho, ukukhiqizwa-cast imiqhele kudinga Ochwepheshe onekhono kakhulu.
