Metal lwezimpawu: ukuphila, izinzuzo nezingozi, ukubuyekezwa

izinkinga zamazinyo kungaholela ukuthuthukiswa ezinye izifo, okungaba sina ngempela. Yingakho sanoma yikuphi ukulimala, kuhlanganise caries, kubalulekile ukuqeda ngokushesha ngangokunokwenzeka. Ukuze wenze lokhu, udokotela wamazinyo kumelwe athathe ngokucophelela ingaphakathi ngamathuluzi ekhethekile, peroxide, utshwala, kungase kudingeke ukuba ususe emsipheni (uginindela). Ngemva kwalezi manipulations, udokotela Ubeka uphawu, okuyinto incike uhlobo izinkinga zamazinyo, kanye amathuba zezimali isiguli. I okungabizi kakhulu futhi kufinyeleleke kukhona ofakwe metal.

Yini impahla isetshenziswa?

Enye igama ofakwe metal - ziyinhlanganisela. Lokhu kungenxa ezazisetshenziselwa ukwenza ukufakwa yabo. Metal ofakwe amazinyo kukhona mercury ingxubevange nge metal ezahlukene (isiliva noma ithusi).

Isiliva ziyinhlanganisela - i ingxubevange, okuyinto, ngaphezu esiliva, kuhlanganisa:

• ithini (kubambezela inqubo lukhuni uphawu);
• i-copper (ingxubevange kwandisa amandla futhi ihlinzeka ephelele uphawu ukuxhumana ezindongeni izinyo);
• zinc;
• mercury.

metal Kugcine ngendlela edingekayo ukuze kwakheke i-ingxube plastic, okuyinto kuleli cala kuyoba ukuqina fast kakhulu ngemuva kokufaka.

ziyinhlanganisela yethusi has ukwakheka efanayo, kodwa isilinganiso ukuxuba abaphila ngayo ihluke ngokuphelele. Ikakhulukazi le osebenza ku olinganise wesiliva nethusi. Kulokhu, ukuthi lingakanani ithusi likhulu kakhulu, futhi ithini esiliva, yingxenye encane kuphela.

izinzuzo

Endaweni yokuqala metal seal kulula kakhulu ukufinyelela kuwo, futhi ngenxa yalokho, cishe noma ubani angakwazi ukukhokha zinamazinyo enempilo. Ngaphezu kwalokho, izinzuzo ezithile nabanye elinama ezifana:

• ubulukhuni namandla kuqinisekisa ukusetshenziswa eside ezimpawu ezinjalo, akudingeki ukuba ishintshwe njalo, ukuthi uzokusindisa isikhathi nemali;
• lula ukusetshenziswa;
• insensitivity ukuze umswakama, ngakho lapho kubhujiswa lesi abathandi itiye kungukuthi ezisengozini.

Futhi, ziyinhlanganisela esiliva kungavimbela yokuphindela caries.

amaphutha

Izibuyekezo eziningi zeziguli bathi metal lwezimpawu babe nezimfanelo engalunganga, njalo baningi kakhulu nonamandla. Lo mbono olwabiwa bamazinyo. Yingakho emazweni amaningi, kabasebabili bewasebenzisa, kanti eRussia ukuhlangabezana ochwepheshe, ngubani uyavumelana nibeke uphawu, umuntu akakwazi ukuthola, ikakhulukazi emitholampilo yangasese.

I yokuntula eziyinhloko, ngokuvumelana Izibuyekezo iziguli kanye nezifundiswa:

• adhesion abampofu;
• okusezingeni eliphezulu conductivity ezishisayo (okungase kubangele ubuhlungu zamazinyo phezu contact nge ukudla okushisayo);
• izinyo ukushintsha kombala, ngaphandle nje kokuba ngokwayo kophawu ngokuphelele iyahluka kwenye umbala koqweqwe lwawo (yingakho ngokuvamile wagqoka namazinyo ukuhlafuna, ukubukeka yobuhle okuyinto inenani encane);

• ukunambitha emlonyeni njalo metal likhona;
• yinkimbinkimbi kokufaka uphawu ezifana kanye nenkathi sokwelapha eside, ngenxa okuyinto wamazinyo uzodinga ukuqhuba okungenani amahora amabili;
• ukuncipha okubalulekile, okungaveza izinyo igawula ukwenzeka, kodwa ngoba lokhu kungase kudinge kokungenela ezengeziwe;
• lichaza ekwakheni ingxubevange kuhlanganisa mercury okuyinto inomphumela omubi emzimbeni.

Ingabe ngidinga ukushintsha ofakwe ezinjalo?

Ngaphezu kwalokho, naphezu kweqiniso lokuthi le nto okuhlala isikhathi eside, ukushintsha metal ofakwe (isevisi siphila iminyaka 10) Ngezinye izikhathi sisadingeka, nakuba lo mthetho abaningi bengakunaki. Uma sicabanga ngakho konke ngokucophelela ngobuhle nangobubi bawo metal ofakwe amazinyo, ochwepheshe abaningi bayenqaba ukusebenzisa lolu hlobo lwezinto ezibonakalayo. Nakuba kwezinye izimo kungase kube. Ngaphezu kwalokho, abaningi patsiety unquma esikhundleni sensimbi ofakwe ngenxa ushintsho umbala izinyo. Uba ukubukeka okungenamsoco futhi kakhulu konakalisa ukumamatheka.

Izimo

Ngaphezu izinzuzo ezisobala futhi sinesisindo, kubalulekile ukuba acabangele yokuthi kokufaka metal ofakwe Ngeke uhlale njalo, ngisho uma isiguli ephikelela ke. Izimo ezinjalo zihlanganisa:

• ukugcwalisa amazinyo anterior;
• khona esikhathini ngalo ingaphakathi ngomlomo yezinye izinto eziyinsimbi, kungenjalo mkhuba okungenzeka galvanism (lamanje kukagesi);
• ukwelashwa ngemisebe endaweni emhlathini noma sonke ebusweni.

ukulimala

Njengoba kushiwo ngaphambili, lo isicelo metal ofakwe ingozi empilweni, ezimweni ezithile ngisho kunokuhle. Lokhu kungenxa khona ingxubevange mercury okuyinto, engena emzimbeni, it ushevu, ikakhulukazi umlomo ezingaphezu kweyodwa uphawu ezinjalo. Izimpawu eyinhloko lesi simo sibangelwa:

• ukuphathwa ikhanda njalo, okuyizinto imithi cishe iqedwe;
• komzimba (uma abazange, -ke zivela, uma isiguli kwake wahlushwa yokungezwani komzimba, futhi kuya kuba nolaka);
• thuthuva Functional organic e nezinso.

Ngaphezu kwalokho, noma kunjalo ungakasitholi ukuthi baziphathe kanjani endabeni metal lwezimpawu ukungena zone ithonya amagagasi kagesi, okuyinto esibhedlela yesimanje eziningi, ikakhulukazi uma kukhona amakhompyutha kanye ekhaya Imishini.

Futhi uzinake ukuthi phawu inikeza isivikelo umonakalo izinyo ngesikhathi inkonzo kuphela. Lapho isisusiwe, izinyo kuyinto nakanjani, futhi kuyodingeka zisuswe futhi emsipheni.

seal ezinjalo kusetshenziswa kakhulu e-USSR. Abantu balithatha izinkinga zezempilo eziningi anikezwe engahlangene kuyinto uphawu metal. Nokho, ucwaningo oluningana nokubuyekeza ukufakazela nomphumela ongemuhle emzimbeni.

Ngingaba ufake ofakwe metal kwabesifazane abakhulelwe?

Ikakhulukazi elimazayo metallic uphawu lisetshenzisiwe umntwana ongakazalwa uma kuba ngakho-ke Welashwa nge unina phambi kowesifazane okhulelwe. Lokhu kungenxa yokuthi i-mercury unekhono ukungena isidumbu sengane ngokusebenzisa umzimba kamama.

Izinyathelo for kokufaka ofakwe metal

Inqubo yokufaka senzeka ngezigaba ezintathu:

1. Ukususwa kwezimiso amasayithi okunobuthi usebenzisa sokuprakthiza ekhethekile. Ngokuvamile, ezilimele dentin caries, ngakho-ke, ukuvimbela ukusabalala ukutheleleka, kufanele ngokuphelele noma ingxenye isusiwe. Ukusebenzisa izinzwa into ozikhethela wena. Uma ebucayi izinyo koqweqwe lwawo basenza umjovo wokubulala izinzwa ku ushingamu.
2. Ukunwetshwa kanye kucutshungulwa umsele impande ekuzaliseni okwalandela. Kulesi sigaba of emsipheni zakhipha, uma kunesidingo, uma kanzima izinyo izicubu kahle kakhulu kanzima. Uma loku kungentiwa, isiguli ngeke uzwe ubuhlungu babulawa njalo. Umthetho oyinhloko izigaba - ukuhambisana nezidingo magciwane. Uma ungenalo ukususa wonke amabhaktheriya ke lapho uvala ingaphakathi uphawu baqala ngenkuthalo ziyanda futhi kungonakalisa izinyo.
3. Ngqo ukugcwalisa. Kuyinto kulesigaba udokotela kuletha ziyinhlanganisela isiteshi kwamazinyo. Kukhona izinyathelo zokuphepha ezithile ukuthi kufanele kube impoqo ukuhambisana, kungenjalo uphawu ngeke ukuwohloka. Ebangeni elingamahora amabili usuka emva iphele kwenqatshelwe udle, intuthu noma aphuze noma yiluphi isiphuzo ngenye indlela yokuthinta izinyo.

Ikakhulukazi metal ofakwe (izibuyekezo siliqinisekise) ukuthi boma amahora 2-3. Ngaphezu kwalokho, usuku olulandelayo luyoba ukuvakashela udokotela wamazinyo futhi ngakho wachitha wokucwebezelisa ebusweni. Lena ukuze kuvimbele ukulimala mucosa ngomlomo ka maholoholo phezu uphawu. Lapho ukufakwa ngendlela efanele, isiguli engazizwa ubuhlungu.

Ngokuvamile, udokotela wamazinyo ihlinzeka isiqinisekiso udumo ngomsebenzi wabo. Naphezu kweqiniso lokuthi impilo inkonzo metal lwezimpawu Uneminyaka ecishe ibe u-10, sewaranti ngeke sidlule eminyakeni emibili. Phakathi nale nkathi, ukubukeka noma yimuphi umonakalo ngokuqondile lwezimpawu noma lapho kubhujiswa lesi ziyinhlanganisela ofakwe ubudala esikhundleni esisha esenzelwe khulula.
