Ukusasazwa kwamazinyo kwi-cermet: iimpawu zeteknoloji

I-prosthesis yamazinyo kwizinyango zamathambo zanamhlanje ithatha indawo ekhethekileyo kwaye ibaluleke kakhulu. Emva kwakho konke, ngenxa yomonakalo kunye nokulahleka okulandelayo akuqinisekisiwe ngumntu. Namhlanje, imboni yamazinyo inikezela ngeentlobo ezininzi zeendlela zokwenza iprothem. Ukuchithwa kwamazinyo phantsi kwe-cermet, engekho enye yezinto ezithandwa kakhulu, unokhehluko phakathi kokuqhutyelwa kwezinye iintlobo zesithsaba. Inyaniso kukuba le ndlela ye-prosthetics yamazinyo ibandakanya isiphumo esihle se-esthétique, ukuthembeka, ukuzinza kunye noxabiso oluphantsi.

Isakhelo esikhethekileyo sesinyithi, esenza isiseko sazo zithsaba kwaye sithatha umthwalo oyintloko ngexesha lokusebenza kwamazinyo, ixhaswa ngezinto zeramic, ezenza umsebenzi wobugcisa. Ngoko ke wabizwa uhlobo, ukuba, mhlawumbi, i-fragile kakhulu kwaye ilungele ukugqoka okukhawulezayo emzimbeni wethu ngamazinyo. I-ceramics ye-Metal, ethathwa njengeteknoloji ethembekileyo neyomeleleyo ye-prosthetics namhlanje, ivumela ukulungisa ngempumelelo le meko yeendaba.

I-Prosthodontics, ngokubanzi, kunye neeprotherapy ngeensimbi zeramic isithsaba, ngokukodwa, kubandakanya ukulungiswa kokuqala, okubizwa ngokuthi ukulungiswa. Emva koko, umlomo womlomo kufuneka ulungiswe ngokucophelela inkqubo enjalo. Ukulungiswa kwamazinyo kwi-cermet ineempawu ezininzi ezinxulumene neemfuno ezongezelelweyo kule ndlela yokuguqulwa kwamazinyo.

Ngokwemilinganiselo yanamhlanje yamayeza omzimba, ubuncinane ubunzima befomati yesitimu kufuneka kube ngu-0.3 mm kwaye ungqimba lwe-ceramic aluyi ngaphantsi kwe-0.8 mm. Isenzo se-arithmetic esilula sinokukwazi ukucacisa ngokukhawuleza ubukhulu bomqhele onokufaneleka, ozinzileyo, olingana nobuncinane be-1.1 mm. Ukuchithwa kwamazinyo phantsi kwe-cermet yenzelwe ukubonelela iiparitha eziyimfuneko.

Enye injongo, elandelwa yinkqubo enjalo yokulungiselela, kukunika iindonga zinozinzo eziqinileyo ezifunekayo ukwenzela ukunyaniseka kwithenda (ukuthambekela okuvumelekileyo kukuphela kwe-7%). Ngaphandle koko, akunakufakwa. Kodwa ingongoma ephambili ehlukanisa ukulungiswa kwamazinyo phantsi kwe-cermet kuyimfuneko yokwakha idilesi ekhethekileyo yomlomo wesibeleko.

Le nkqubo engamangalisi yenziwa ngokusebenzisa i- anesthesia yendawo. Ukwelashwa kwamazinyo okugqithisa amazinyo kwi-cermet kwenziwa njengokuba kunokwenzeka. Ukusebenzisa i-turbine boron (i-speed speed of rotation-250,000 rpm), ehlonywe nge-diamond tip, ugqirha wamazinyo ngumzimba onzima wamazinyo. Ukujongana neendawo eziphambili, i-disc yokuhlukanisa okukhethekileyo okanye i- turbine tip isetyenti, intloko yedayimane enesantya esincinci ngaphezu kwesikhokelo esakhiwe kuyo.

Ukufuna indawo yokuhlafuna kubaluleke kakhulu ukugcina isimo sabo se-anatomiki. Ixhego lokuqala, zombini kwipintile kunye ne-vestibular, yenziwa ngaphantsi kwe-gum umda malunga nesiqingatha semilimitha. Emva koko, i-scaffold ephezulu ihlanganiswe kunye, kwaye izicubu ezinamazinyo ezinzima zongezwa ngokugqithiswa ngumbono wesigxina. Emva koko iikona ezibukhali zijikelezwe, kwaye kule nkqubo, ukubunjwa kwesikhokelo kungaqwalaselwa ngokupheleleyo. Umsebenzi oyintloko wongcali wamazinyo kwinqanaba lokulungiselela kukuthintela ukugqithisa kwezinyo. Ngaphandle koko, iimbilini ziya kufa. Ngenxa yale njongo, kusetyenziswe inkqubo yokupholisa umoya.

Kwaye ekupheliseni into enomdla. Iprosthetics yaqulunqwa yi-Etruscans, eyayiphila kwintsimi ye- Apennine ipeninsula yamashumi amathathu eminyaka edlulileyo. Kwaye kwavela ama-dentures e-porcelain kwikhulu leshumi elinesibhozo. Enyanisweni, ubugcisa bezintlu zanamhlanje, ngokungafani nobuchule beeminyaka engama-300 edlulileyo, luvumela ukuba nabani na ofuna ukumomotheka inyosi yaseHollywood.
