Ukuzaliswa kwamazinyo

Yintoni ukuzaliswa kwezinyo kuyazi, kubonakala, wonke umntu. Nangona kunjalo, kuphela ngokwemiqathango jikelele. Masizame ukuqonda oko kwenzekayo nale nkqubo.

Ukuzaliswa kwamazinyo kuqala ngento yokuba ugqirha wenza i-anesthesia ukukhupha isigulane sentlungu. Emva koko, uyasusa ngokucophelela zonke izicubu zezinyo ezichaphazelekayo. Eli nqanaba libaluleke kakhulu, kuba Kwanele ukushiya ubuncinci obungasetyenzisiweyo bokubola kwezinyo - kwaye emva kobuninzi bonyaka unotyikityi kufuneka utshintshwe. Ekuqaleni, umgangatho wokususwa kwezinto ezixhomekeke ngqo kuxhomekeke kumava ogqirha, kodwa ngoku ubugcisa bobugcisa buvumela ukuqikelela ngokuchanekileyo ubungakanani balo ngobuncedo bee-detectors ezizodwa, ezisetyenziswa kwizinyo. Siyabonga kubo, akudingeki ukuba ususe amazinyo ngokucacileyo, ngoko mhlawumbi akukho zicuksu ezinesifo se-caries.

Emva kokususwa kwezicubu ezigulayo, ugqirha ubeka inyolo ekuphumeni (ngenxa yokuba iimpawu kufuneka zomeke ngexesha lokufakelwa) ngoncedo lwezixhobo ezikhethekileyo (i-rubber cofferdam headcarf, i-wedge yamazinyo okanye i-retraction thread). Kwaye emva kokufezekisa zonke ezi zonyango ugqirha uqala ukwenza ngokuzenzekelayo ukuzalisa izinyo.

Ziziphi izizaliso zamazinyo?

Xa umntu ejika kwiizinyo zomzimba kunye nombuzo wokuba kuza kuba neendleko zokuzalisa izinyo, uyazicingela ngaluphi uhlobo lwesitywina azakubeka, kwaye malunga neendleko zokuzaliswa kuxhomekeke kulolu khetho.

Okokuqala, iimpawu ziyahlukana zibe zisesigxina kwaye zisigxina. Ixeshana, njengoko igama libonisa, libekwe ixesha. Oku kuyimfuneko ukuze ugqirha wamazinyo athole ukuba i-nerve ibonakele okanye ukuze ibeke iyeza phantsi kwayo. Izibonakaliso ezingapheli zibekwe ubuncinci beeminyaka emininzi, kwaye i-ide - iminyaka emashumi.

Izibonakaliso eziqhubekayo zenziwa ngezinto ezahlukeneyo.

1.Metallic. Yenziwe ngama- alloys ensimbi kunye ne-mercury. Kukholelwa ukuba inyolo yokuzalisa izilwanyana ezinjalo zithembeke kakhulu, ingakumbi ukuba i-alloy iphezulu yomgangatho (kunye nesilivere). Ezi zimpawu ziyiminyaka engama-20 ukuya ku-30 ubudala, ngaphandle kokuba, ngokuqinisekileyo, enye i-foci ye-caries yenziwe ngokuzayo. Nangona kunjalo, ukufakwa kwale miqulu kuthatha ixesha elide, ngenxa yokuba Bomile malunga neeyure ezingama-3. Enye into engabonakaliyo kukubonakala, awukwazi ukubeka uphawu olunjalo kumazinyo angaphambili.

2. I-Cement. Bahluke ngokubaluleka. Ngokuqhelekileyo kukho i-phosphate ne-ionomere yeglasi. Ukuzaliswa kwe-phosphate ngoku kungabizwa ngokukhuselekileyo kuthiwa yi-relic yexesha elidlulileyo. Baqhayisa ngamandla, bawa ngaphandle kwaye bangahambelani kakuhle kwimida. Ubomi bentsebenzo yabo ayidluli kangangexesha leminyaka emibini. Ngoko ke ngoku naziphi na iziqu ezifanelekileyo ezinjalo eziya kuthi aziyi kunika. Ukuzaliswa kwe-Glass ionomers kuyinto ethe gqolo ngakumbi kwaye ukubunjwa kwabo kukuvimbela ukuphuhliswa kwee-caries. Nangona kunjalo, umgangatho wabo, unjalo, ushiya into enqwenelekayo, ngoko-ke asetyenziswa ngokuyinhloko ekutywinzeni amazinyo omntwana okanye abekwe phantsi kwesithsaba.

3. Olunye uhlobo oluthile lokuhlala ixesha elifutshane kwaye uhamba ngokukhawuleza kwiimpawu ezidlulileyo - iplastiki.

4. Ukuzaliswa okudibeneyo kwahlula kwii-subspecies eziliqela:

- Ukuzaliswa kwama-acrylic kunamandla kakhulu, kodwa ngokuqhelekileyo kubangele i-caries yesibili kunye ne-pulpitis.

- izalathisi ezineesiseko ze- epoxy resins ziyingozi kakhulu, kodwa zigqithise ngokukhawuleza kwaye zibe mnyama ngaphezu kwexesha. Ngoko ke, ukuba ufuna ukuzalisa amazinyo angaphambili, ungasebenzisi izimbozo ezinjalo.

- Ukugqitywa kokukhanya okugqityiweyo kokugqibela malunga neminyaka emihlanu. Zizo zizitifiketi ezibhekwa njengezona zininzi zanamhlanje. Xa zibonakaliswe ekukhanyeni kwe-ultraviolet, zenza i-polymerize kancane, ebenza ukuba benze isimo sabo kwaye bakhethe umthunzi.

5. Enye indlela yokutywinwa kwindlela yamanje yimiba. Ngale ndlela yokutywinwa, umonakalo wenziwa kwinqaba kwizinyo, kwaye ngoko, ngokutsho kwalo, into enjenge-prosthesis eyenziwe ngesinyithi, i-porcelain okanye iplastiki yenziwe. Emva koko i-prosthesis iqhotyoshelwe kwizinyo. Ukungalungi kweli ndlela kungabizwa ngexabiso eliphezulu.

Kwimeko apho ama-caries adluliselwe kwi-pulpitis, iingcambu zomngcipheko ziya ku funeka zitywinwe, ezihlala zingenanto emva kokususwa kwenzwa. Izinto zokwenza ukutywinwa kweengcambu zengcambu zihlukeneyo, ukhetho lwabo luxhomekeke kwiingcebiso zedokotela wamazinyo kunye nemali ozimisele ukuyihlawula.
