Yuav ua li cas yog kev kho hniav ntaub ntawv?

Kev Kho Hniav ntaub ntawv uas yog pib cov ntaub ntawv rau qhov kev npaj ntawm tshwj xeeb formulations prostheses, crowns thiab lwm yam pab kiag li lawm yuav tsum tau nyob rau hauv txoj kev xyaum ntawm orthodontics thiab kho hniav. Lawv yog cov muaj nyob rau hauv abundance. Txawm li cas los, cov kws txawj muaj coj lawv mus rau kev cais. Yog li ntawd niaj hnub no muaj ntau yam uas loj thiab me kev kho hniav kho vajtse.

Ntsiab nta

Muaj ib tug xov tooj uas yuav tsum tau yuav tsum tau ntsib los ntawm tag nrho cov kev kho hniav uas siv:

• Tu. Tag nrho lawv muaj kom tau raws li tej yam qauv thiab tsis muaj lub qhov ncauj.
• Toxicology. Lawv yuav tsum tsis txhob thab plaub thiab ua ib qho kev tsis haum cov tshuaj tiv thaiv.
• Zoo nkauj. Lawv yuav tsum rov qab ua qhov ncauj cov ntaub so ntswg.
• Tshuaj. Lawv tshuaj nyob tus yeees yog npaj mus yuav lawm. Lawv yuav tsis corrode.
• Lub cev. Lawv yog cov yeej ib txwm muaj zog, tsis txhob hloov lawv loj, raws li zoo raws li coj-resistant.
• Technology. Lawv yog cov yooj yim mus lis, npaj thiab muab cov kev tsim nyog rau daim ntawv.

ntsiab

Basic kho hniav ntaub ntawv no yog siv los tsim ib tug prosthetic ntsaws kiag li lawm. Ntawm lawv yog cov:

• Co (xws li precious kub, silver), thiab lawv tej yeeb koob. Niaj hnub no nyob rau hauv ib tug kev kho hniav xyaum, ib tug ze li ntawm 500 txawv hlau alloys. Palladium, kub, platinum - ib tug txheej txheem. Cov khoom no tsis yog-tshuaj lom, check thiab tsis corrode. Kawm titanium alloys, zaum tau tuaj mus rau lub xaus hais tias qhov no yog ib tug kuj zoo kawg thiab ib tug pheej yig dua lwm txoj rau kub.
• Tais diav ntim chaws. Ntawm no yog hais txog iav thiab iav ceramics (vitrified). Los ntawm cov thawj khoom crowns, cov txuas hniav, tabs. Cov yav tas yog siv rau prosthetic kho hniav pem hauv ntej kab.
• Polymers - pheej yig tsis tau check kev xaiv kom tsim tau ib tug tshem tau thiab tsau prostheses. Siv cov khoom rau kev kho hniav hniav.
• Composite ntaub ntawv. Nws yog vim hais tias lawv ua tau cov ntsaws. Lawv yog siv rau cov cladding tag nrho cov hlau qhov chaw ntawm hlau-yas prosthesis. Muaj nyob rau hauv daim ntawv ntawm cov kua, muab tshuaj txhuam.

Thaum sib txawv theem ntawm cov creation ntawm prosthetic siv tshwj xeeb koom haum pab kho hniav uas siv:

1. Tswv yim txhais tau tias tsim nyog los tsim snapshots, maps ntawm ib qho nyuaj thiab mos mos ntaub so ntswg. Raws li ib tug tshwm sim, cov kws muaj txuj tau txais lub chaw ua hauj lwm, diagnostic los yog koom haum pab qauv ntawm lub neej yav tom ntej prosthesis.
2. Sculpting ntaub ntawv uas yuav tsum tau los tsim lub prosthesis stamp, yas los yog apparatus.
3. Moulding cov ntaub ntawv - kho hniav yam uas yuav pab tau lub kawg daim ntawv rau lub tom ntej casting. Lawv yuav tsum muaj tej yam ntxwv. Ua ntej, xws ntaub ntawv muab ib tug ntshiab qhia ntawm lub neej yav tom ntej yam khoom. Secondly, lawv yuav tsum muab tau yooj yim sib cais los ntawm lub resulting qauv. Thaum kawg, lawv thiaj sai heev (tsis pub dhau 10 feeb).

Nyob rau hauv cov kev yees duab hniav ntaub ntawv tsis qhia tag nrho nws cov nta. Yog li ntawd, cov kws kho hniav thiab prosthetic cov tub txawg xaiv expendable nyiaj thiaj tau tuaj rau lub hauv paus ntawm lawv cov kev paub. Tuam txhab uas muag uas ua rau lawv ib tug heev heev. Txawm li cas los, tsis yog txhua txhua ua zoo thiab txhim khu kev qha cov khoom.
