Izinto ezinhle kakhulu zokwelashwa komsele wezimpande - umqhele we-zirconia

Kuyini ukwelashwa kwezimpande?

Uma izinyo line-pulpitis noma i-apical periodontitis, ukwelashwa okufanele ukwelashwa kwe-root canal. Kalula nje, inhloso yokwelashwa komgudu wezimpande wukuzama susa izicubu ze-necrotic, amabhaktheriya nemikhiqizo yawo emgodini wezimpande, futhi ukwakha i-taper ethile, nokugcwalisa umsele wempande nge-gutta-percha oyinyumba ukugcwalisa izinto, ukuze kuzuzwe inhloso yokugcwalisa okunezinhlangothi ezintathu kanye vimbela umsele wempande. Ukuhlaselwa kabusha kwama-bacteria kukhuthaza ukululama izicubu periapical futhi ubuyisela umsebenzi evamile amazinyo.

Yiziphi izinyathelo zokwelapha umsele wempande

1. Ukulungiswa komsele wezimpande - vula i-tooth nerve cavity, susa ngokuphelele izicubu zezinzwa zezinyo ezinesifo, ulinganise ubude bempande, futhi wandise umsele wezimpande.

2. Ukuchelela komsele wezimpande kuwumsebenzi ophindaphindiwe ekwelapheni komsele wezimpande. I izingcezwana ezincane zento ephilayo emgodini wempande kanye nezinhlayiya ezinhle izicubu eziqinile ezisikiwe zigezwa ngesibulali magciwane.

3. Ukukhipha amagciwane ezimpandeni - faka izidakamizwa ezikhethekile zokubulala amagciwane ezimpandeni umsele, bese uvala imbobo ngento yokuvala yesikhashana ukuze uqhubeke nokubulala amagciwane umsele wempande.

4. Ukugcwaliswa komsele wezimpande - sebenzisa izinto zokugcwalisa zamazinyo ukuze uvale impande yezimpande ngokuqinile ukuze uvimbele amagciwane nezinye izinto ezithathelwanayo ukungena kabusha emgodini wezimpande futhi kubangele ukuvuvukala okusha.

Ngakho-ke ngemva kokwelashwa kwezimpande, yiziphi izinto esingazisebenzisa ukwelapha?

1. PMMA : singasebenzisa i-Bloomden PMMA njengento yokugcwalisa.

Izinzuzo ze-PMMA ze-root canal

• intengo ephansi

• Isimo sezulu esihle kakhulu nokumelana nemisebe ye-UV.

• obala.

• Ukucwebezela okuphezulu nobulukhuni (uma kulungiswa)

• Izinzile ngokwezinga.

• Ukumelana okuhle nokuhuzuka - imihuzuko engaphezulu ingasuswa (ngemuva ukuguqulwa)

2. Umqhele we-Porcelain: singenza umqhele wokwelashwa kwezimpande.

Sihlala sikhetha umqhele we-porcelain kanye nomqhele wensimbi empilweni yethu yansuku zonke, kodwa I-Bloomden incoma ukukhetha imiqhele ye-zirconia, ngakho-ke yiziphi izinzuzo zayo umqhele we-zirconia uma kuqhathaniswa nomqhele wensimbi?

Izinkinga nge-porcelaincrown yensimbi:

1.Kunenkinga yokuhlangana phakathi kwensimbi ne-ceramic, futhi kulula awe.

I-2.Metals inezinkinga ze-oxidation kanye nezinkinga zokugqwala kwe-asidi.

Endaweni ye-acid-base yomlomo womlomo, amazinyo ensimbi-ceramic akhona engazinzile ngaphansi kwesenzo samabhaktheriya, futhi kuyoba khona insimbi ethile ukuphazamiseka ngesikhathi CT noma MRI.

3.Izindaba zobuhle.

Imiphetho yamazinyo e-metal-porcelain amnyama.

Kulezi zinkinga ezintathu, izinzuzo zamazinyo e-zirconia porcelain:

I-1.Zirconia imiqhele ayinayo inkinga yokubopha phakathi kwensimbi kanye izitsha zobumba.

I-2.Zirconia izinzile kunensimbi.

I-3.I-Zirconia ine-translucency enhle ne-refraction, futhi ngeke ibonakale imnyama imigqa entanyeni yezinyo, ukuze intamo yezinyo nayo ikwazi ukufeza a umphumela omuhle wobuhle, ongenakwenzeka ukubamba ngensimbi i-porcelaincrown.
