Metal amatywina: ebomini, ngobuhle nangobubi, ncomo

iingxaki zamazinyo kungakhokelela kuphuhliso nezinye izifo, nto leyo kuba kubi kakhulu. Kungenxa yoko le nto nawuphi na umonakalo, kubandakanywa yidityaniso, oko kuyimfuneko ukuze kupheliswe ngokukhawuleza kangangoko kunokwenzeka. Ukuze benze oku, wamazinyo wolenza ngenyameko Faka izixhobo ezikhethekileyo, peroxide, utywala, kusenokufuneka ukucima luvo (ido-). Emveni kwezi zazo, ugqirha ubeka itywina, leyo ixhomekeke kuhlobo iingxaki zamazinyo, kwakunye amathuba zemali yesigulana. Ezingabizi kakhulu yaye zifikeleleke ke kwiziseko yesinyithi.

isetyenziselwa ntoni eziphathekayo?

Elinye igama le ukuwavala yesinyithi - amalgam. Oku kungenxa yokuba izinto esetyenziselwa yokufaka. ofakwe Metal for amazinyo mercury ingxubevange kunye nentsimbi eyahlukileyo (isilivere okanye ubhedu).

amalgam Silver - an intsila, leyo, ukongeza zesilivere, iquka:

• tin (ehla inkqubo lukhuni itywina);
• copper (ingxubevange kwandisa amandla kwaye ibonelela epheleleyo qhagamshelana itywina kunye iindonga izinyo);
• zinc;
• mercury.

metal Last efunekayo ukwenza umxube iplastiki, nto kulo mzekelo uza kuba lukhuni fast kakhulu emva kokufakwa.

amalgam ubhedu unalo ukwakhiwa efanayo, kodwa umlinganiselo okuxuba yahluke kakhulu. Ingakumbi oku kusebenza olinganise nangesilivere nangobhedu. Kulo mzekelo, isixa ubhedu likhulu kakhulu, nebhekile nesilivere, kuphela isahlulo esincinci.

buhle

Kwindawo yokuqala amatywina etyhidiweyo zezona ifikeleleke kwaye, ngenxa yoko, phantse nabani na bakwazi ukuba amazinyo enempilo. Ukongeza, iingenelo ezikhethiweyo kunye nezinye izinto ezinjalo;

• nobulukhuni namandla eqinisekisa ukusetyenziswa ixesha elide ezinjalo lamatywina, akuyomfuneko ukuba itshintshwe ngamathuba athile, ukuba uya konga ixesha nemali;
• lula ukusetyenziswa;
• novelwano ukuze ukufuma, ngoko ukutshatyalaliswa abathandi leti abayi zisengozini.

Kwakhona, oko amalgam yesilivere kunokukhusela ukwenzeka yidityaniso.

ukushiyeka

Ukubuyekezwa ezininzi izigulane zithi ezitywine metal abe neempawu ezimbi, ezo kakhulu zizininzi, zinamandla ngakumbi. Le mbono kwabelwana ngabo bamazinyo. Yiloo nto kumazwe amaninzi, bangabi saba lisetyenziswe onke, yaye eRashiya ukuhlangabezana iingcali, abavumelanayo ukubeka lomsesane wokutywina, umntu akakwazi ukufumana, ingakumbi kwiiklinikhi zabucala.

Bobubi eziphambili zezi, ngokutsho ncomo ezigulane kunye neengcali:

• adhesion amahlwempu;
• eliphezulu conductivity thermal (oko kubangela intlungu zamazinyo phezu wadibana ukutya eshushu);
• izinyo kombala, ngaphandle nje kokuba ngokwako ngetywina kakhulu iyahluka ukusuka wayesebenzisa umbala (nto leyo nto behlala kwambatha amazinyo ukuhlafuna, imbonakalo ubuhle lwalo ixabiso elincinane);

• ukunambitha emlonyeni rhoqo but is ekhona;
• ukuntsonkotha ukufaka itywina kwakunye ixesha enganyangekiyo elide, ngenxa apho ugqirha wamazinyo kuya kufuneka aqhube iiyure ezimbini ubuncinane;
• izinto shrinkage, nto leyo kungabangela izinyo NOKUCUKUCEZA yenzeke, kodwa ngenxa yokuba oku kufuna ungenelelo olongezelelweyo;
• kuhlanganiselo ingxubevange iquka mercury, nto leyo iba nefuthe elibi emzimbeni.

Ngaba kufuneka ukutshintsha kwiziseko ezinjalo?

Ukongeza, nangona ukuba le nto ixesha elide, ukutshintsha ukuwavala zesinyithi (ubomi inkonzo engama-10) wambi kwakusafuneka, nangona lo mgaqo abaninzi ngoyaba. Ukuqwalasela zonke iingenelo neengozi ukuwavala zesinyithi ezisetyenziswa amazinyo, iingcali ezininzi bayala ukusebenzisa olu hlobo eziphathekayo. Nangona kwezinye iimeko kusenokuba. Ukongezelela, abaninzi patsiety isigqibo ukubuyisela ukuwavala zesinyithi ngenxa ukutshintsha umbala izinyo. Yena uba inkangeleko mpilweni yaye konakalisa ngokubalulekileyo uncumo.

Izimo

Ukongeza iingenelo ezicacileyo kunye nokuvuzwa, kuyimfuneko ukuba yokuba kokufaka ukuwavala metal akakwazi kuhlala ingqalelo, nokuba isigulane unyanzelisa kuyo. Izimo ezinjalo ziquka:

• ezanelisa amazinyo sobuKristu;
• ubukho em- ngomlomo kwezinye izinto yesinyithi, kungenjalo ngumkhuba of galvanism (current galvanic) kunokwenzeka;
• therapy radiation kwingingqi ngomhlathi okanye lonke ubuso.

ukulimala

Njengoko ngaphambili kukhankanyiwe, ezi zinto yesinyithi isicelo yingozi empilweni, kwezinye iimeko ngaphezu ezilungileyo. Oku kungenxa ebusweni intsila mercury leyo, bangene umzimba, oko ubuthi, ingakumbi ngaphezu kwesinye itywina onjalo emlonyeni. Iimpawu eziphambili zale ziyenzeka:

• ebuhlungu rhoqo, ezo amayeza phantse bungaveli;
• ziyabagulisa (ukuba abazange zinqongophele khona, ngoko ke kuvela, ukuba isigulane ngaphambili ubunzima evela nokwaliwa, kuya kusiba ndlongondlongo ngaphezulu);
• ukuphazamiseka ezisebenzayo komgquba nezintso.

Ukongeza, asikalifumani indlela ukuziphatha kwimeko amatywina yesinyithi ukuba bangene kwindawo echatshazelwa amaza, nto leyo kwisibhedlele mihla kakhulu, ingakumbi xa kukho iikhompyutha kunye zombane ekhaya.

Kananjalo kubalulekile ukuba siqaphele ukuba eli tywina inika ukhuseleko ngokuchasene umonakalo izinyo kuphela ngexesha lenkonzo. Xa siyisuse, izinyo ngokuqinisekileyo kufa, yaye kuya kufuneka ukuba kususwe kunye luvo.

Ezo zamanzi ezisetyenziswa kwi-USSR. Abantu for iingxaki zempilo eziliqela anikwe yaye nomqhubi ukuthatha ukuba ngetywina yesinyithi. Noko ke, uphando olwenziweyokwakunye kunye nohlaziyo Makazicikide nefuthe elibi emzimbeni.

Ndingenza ndibeke ukuwavala yentsimbi kumabhinqa akhulelweyo?

Ingakumbi ebuntsimbi uphawu yingozi lisetyenziswa usana olungekazalwa ukuba kunjalo oko iphathwa kunye nonina phambi komfazi okhulelweyo. Oku kungenxa yokuba mercury uyakwazi ukungena kwi umzimba umntwana leyo esiswini sikanina.

Amanyathelo sokuba kokufaka kwiziseko metal

Inkqubo yokufaka ithatha kuqhubeka ngokwezigaba ezintathu:

1. Ukususwa sites ezingcolisekileyo usebenzisa drill okhethekileyo. Ngokuqhelekileyo, yidityaniso dentin yonakele, ke ngoko, ukuthintela ukosuleleka yintsholongwane, kufuneka ngokupheleleyo okanye ngokuyinxenye isuswe. Ukusebenzisa zomzimba ungayikhetha. Ukuba ezibuthathaka izinyo wayesebenzisa basaqhuba ngenaliti iintlungu kungena intshungama.
2. Ukwandiswa nokusingathwa ingcambu emjelweni ukuze ligcwalise ezilandelayo. Kweli nqanaba le luvo Wasusa, ukuba kuyimfuneko, ukuba izinyo inyama nzima kakuhle kakhulu kakhulu. Ukuba oku akwenziwa, isigulana siya buhlungu rhoqo nodandatheko. Eyona ulawulo izigaba - nokuhambelana neemfuno kweentsholongwane. Ukuba ngaba ukususa zonke iintsholongwane, ngoko xa uvala lweHo- itywina beqala ukwanda ngamandla kwaye bonakalisa izinyo.
3. Ngqo ukugcwala. Kuyinto kwesi sigaba ugqirha ozisa itshaneli amalgam wamazinyo. Kukho amanyathelo athile ekufuneka zibe inyanzelekile ukuba ukuthobela, kungenjalo itywina ziya kugxagxiseka. Kwisithuba iiyure ezimbini emva kokuba yaphuse kokuba Akuvunyelwe ukutya, umsi okanye asele nayiphi na isiselo enye indlela uthinte izinyo.

Ingakumbi ofakwe metal (reviews ukuliqinisekisa) ukuba zome iiyure 2-3. Ukongeza, kuya kuba ngosuku olulandelayo ukutyelela ugqirha wamazinyo kwakhona ngoko wachitha ipolishi komhlaba. Oku ukwenzela ukuthintela umonakalo isifo ngomlomo uburhabaxa phezu kobuso itywina. Xa zifakwe kakuhle, isigulana akuthethi zintlungu.

Ngokuqhelekileyo, wamazinyo ibonelela ngesiqinisekiso umsebenzi wabo. Nangona ubomi yenkonzo amatywina but is malunga-10 iminyaka, ixesha isiqinisekiso ayiyi kudlula kwiminyaka emibini. Ngeli xesha, imbonakalo nawuphi na umonakalo ngqo lamatywina okanye ukutshatyalaliswa ukuwavala amalgam endala indawo entsha kwenziwa simahla.
