Hom Tshuaj Txheej Txheem Hniav - Titanium vs Zirconia

Keeb Kwm Kho Hniav Daim Ntawv Teev Tseg

Ua ntej rau qhov no thiab txawm txij li thaum ntawd, lwm cov ntaub ntawv tau raug kuaj thiab sim. Vitreous carbon yog ib yam khoom uas ua haujlwm zoo heev hauv fusing to pob txha, tab sis yog qis thiab muaj lwm yam teeb meem ua rau nws tsis zoo rau kev siv ua hniav kev cog hniav. Titanium zoo li ib yam khoom zoo tagnrho-nws lub zog ua nws tseem ceeb, tswv yim thiab paub tseeb. Cov thawj lub implants tau ntshiab titanium, tab sis lawv muaj me ntsis muag muag ces ib qho alloy yog tsim los mus kov yeej cov khoom tsis zoo.

Hnub no, zoo tshaj 95% ntawm cov kev kho hniav raug muab tso rau hauv yog titanium alloys. Muaj ntau pua ntawm cog kev lag luam thiab tshuab thoob ntiaj teb thiab thaum twg cov kev cai thiab phais raws li kev ua raws li, kev vam meej ntawm cov implants yog tag nrho cov zoo tshaj 98% txawm tom qab 10 xyoo.

Txij li thaum titanium kev kho hniav kev kho mob tau siv, nws tsis tau muaj ib daim ntawv qhia txog kev ua xua lossis fab rau cov hlau. Txawm li cas los xij, muaj qee leej neeg uas muaj kev fab tshuaj rau lwm cov hlau (xws li kev muaj kuab nickel fab qaub qis tshaj 5%) thiab / lossis tsuas muaj kev txhawj xeeb txog cov hlau hauv lub cev.

Zirconium-Cov Hlau-Kev Xaiv?

Txhawm rau txhim kho cov kev txhawj xeeb no thiab muaj qhov kev xaiv cog rau cov neeg no, ntau lub tuam txhab tau tshawb nrhiav thiab kev loj hlob mus rau hauv cov "tsis muaj hlau". Qhov no tau coj mus siv ntawm lwm cov hlau hu ua zirconium, uas yog ib kab hauv qab hauv titanium hauv cov tshuaj lub sij hawm tshuaj. Zirconium thawj ua nrov nyob rau hauv nws cov crystalline sau lo lus zirconia daim ntawv vim nws qhov sib xws rau lub flawless pob zeb diamond. Rau kev siv kev kho hniav, nws yog siv rau hauv daim zirconium oxide ZrO2. Nws tsis yog neeg dawb huv ZrO2-muaj cov kab uas muaj hlau hu ua hafnium (Hf) thiab cov oxide muaj nrog yttrium (lwm yam hlau) los txhim kho nws cov khoom. Qhov tshwm sim yog xim dawb opaque-looking thiab nyob rau hauv daim ntawv no, hais tias yog ib qho ceramic, tab sis muaj cov hlau atoms hauv cov khoom.

Cov khoom siv yog muaj zog thiab muaj zog thiab tau siv los ua cov yas thiab cov txuas hniav. Nrog rau kev tshawb nrhiav lwm cov khoom cog, nws tau pom tias zirconia tseem fused rau cov pob txha (osseointegrated) ntau xws li titanium.

Qhov zoo ntawm Zirconia Dental Implants

Cov neeg tawm tswv yim ntawm zirconia xeev ntau qhov zoo ntawm cov khoom:

1. Tsis muaj xim xim ntawm cov hlau uas ua los ntawm cov pos hniav

2. Tsis muaj corrosion ntawm zirconia li nrog titanium

3. Tsis muaj piezo-hluav taws xob ntawm nruab nrab ntawm qhov txawv ntawm lub qhov ncauj

4. Nws yog cov thev tsis yog kev ua haujlwm

Raws li ib lub chaw muag khoom ntawm zirconia kev cog kab mob: "Cov kev hloov ntawm cov khoom siv los ntawm cov khoom siv hluav taws xob los ntawm kev siv dag zog yog qhov teeb meem tshwj xeeb tshaj yog thaum muaj ib qho tshuaj cog rau hauv qhov chaw tua hluav taws los ntawm lub cev tib neeg lub cev."

Rau lwm cov tes, thaum zirconia muaj nws cov perks, ntau tsawg dua paub txog lub luag hauj lwm ua si los ntawm qhov kev hloov ntawm qhov chaw nyob ntawm osseointegration ntawm zirconia kev kho hniav implant
