Niaj hnub no, 3D tshuab luam ntawv tau dhau los ua menyuam yaus hauv kev kho mob nrog kev pabcuam zoo. Muaj ntau yam khoom siv kho mob ntxiv. Cov khoom siv hlau kho mob rau kev cog hniav thiab cov khoom siv orthopedic: stainless hlau, cobalt-based alloys thiab titanium alloys. Titanium alloys yog cov khoom siv feem ntau siv hauv kev kho mob ntawm cov ntaub so ntswg tawv. Vim nws cov biocompatibility zoo thiab txhua yam khoom, nws kuj yog cov khoom siv zoo tshaj plaws rau kev cog hniav sab hauv. Kev kho mob titanium daim hlau, titanium rau tes, thiab titanium mesh tau dav siv rau qhov ncauj thiab maxillofacial trauma, sab hauv fixation, thiab resection ntawm maxillofacial cov ntaub so ntswg nrog rau lub puab tsaig, mandibles, osseous phab ntsa, craniums, emulsions, thiab hais txog. Nws tseem tuaj yeem tsim cov pob txha taub hau rau pob txha taub hau ntxiv, thiab microporous titanium mesh netting rau kev kho cov pob txha taub hau puas thiab dura mater. Kev tsim cov hauv paus hniav ntawm qhov ncauj, tus kheej lub hauv paus, dentin brackets, crowns thiab txuas hniav thiab lwm qhov chaw ntawm qhov ncauj implantology, orthodontics, thiab lwm yam .. Ski-mandibloy cov ntaub so ntswg rau implantation ntawm sedentary cov ntaub ntawv thiab cov txheej txheem ntawm kev npaj yog lub ntsiab yam tseem ceeb cuam tshuam qhov zoo ntawm kev kho dua tshiab. Kev vam meej maxillofacial restorative thiab reconstructive phais kuj tseem ceeb heev.
Txij li thaum xyoo 1940, ntau tus kws tshawb fawb tau kawm txog qhov ua tau zoo ntawm titanium bioperformance. Cov kev tshawb fawb muaj ntau yam kev qhuab qhia xws li lub cev, tshuaj, biomedical thiab advanced electron microscopy thiab biochemical tsom xam. Xyuas kom muaj qhov zoo biocompatibility, mechanical compatibility, thiab cov qauv tsim nyog rau titanium implants xws li cov txheej txheem, thiab kev loj hlob ntawm kev cog hniav yog qhov tseem ceeb.
Kev tshawb fawb ntawm titanium implant cov ntaub ntawv rau sab hauv tib neeg nto muaj xws li:
(1) Kev txhim kho ntawm cov uas twb muaj lawm thiab kev txhim kho ntawm txoj kev ua kom lub ntsej muag tshiab los txhim kho kev hnav thiab kev tiv thaiv corrosion ntawm cov khoom cog, thiab ntxiv dag zog rau kev sib raug zoo ntawm titanium alloy cov ntaub ntawv thiab bromothalamus mineral concentrations; (2) Kev txhim kho ntawm cov uas twb muaj lawm thiab kev txhim kho ntawm txoj kev ua kom lub ntsej muag tshiab los txhim kho qhov hnav thiab corrosion kuj ntawm cov khoom cog.
(2) Tus kheej kev cai 3D mesh cog tsim thiab npaj.
Hais txog kev kho cov ntaub so ntswg nyuaj thiab hloov cov ntaub ntawv 3D mesh titanium alloy implantation 3D hlau luam ntawv kev tshawb fawb yog ib qho kev qhia dav dav dav rau ntau yam kev qhuab qhia. Yuav tsum muaj kev sib txuas lus zoo dua ntawm cov kws kho mob thiab cov kev tshawb fawb tom ntej yog:
(1) CT scan cov ntaub ntawv ntawm txawv extracranial defects, reconstructed tom qab CAD 3D ntxeem tau qauv implants rau tus kheej tsim tsim;.
(2) Hauv kev tsim cov qauv mesh, biochemical simulation tsom xam bionic tsim tawm tswv yim cov qauv mesh thiab kev faib tawm kom tau raws li qhov nruj txaus thiab lub zog los daws qhov teeb meem ntawm kev tiv thaiv siab, thiab tib lub sijhawm, yuav tsum muaj qee yam zoo kom ua tau raws li qhov xav tau. xav tau kev pab. Nws xyuas kom meej tias nws yuav tsis deformed thiab puas tom qab cog rau hauv tib neeg lub cev;.
(3) Kev tshawb fawb cov ntaub ntawv qhia ua rau hauv vitro kev sim tshuab thiab hauv vivo implantation thwmsim, kho qhov pore tsis, cov khoom siv kho tshuab ntawm cov qauv mesh ntawm titanium alloy thiab cov txheej txheem sab hauv. Cov txheej txheem ntawm kev kho mob implantation yuav nrawm dua.
(4) 3D hlau luam ntawv thev naus laus zis yog siv rau kev tsim ntawm 3D reticulated titanium alloy stent qauv kom kov yeej ntau qhov tsis xws luag hauv cov txheej txheem kev tsim cov txheej txheem ntawm bracket complex shape fabrication thiab internal microstructures uas tsis tuaj yeem tswj tau yam tsis muaj kev txwv ntawm qhov nyuaj. lub bracket geometry, tswj lub aperture, porosity, thiab fabrication ntawm bracket lub porosity thiab microstructures. Tsis tas li ntawd, nws muaj peev xwm ua kom zoo dua cov qauv ntawm pre-stent los ntawm kev txheeb xyuas cov ntsiab lus finite. Qee qhov tshwj xeeb yuav tsum tau ua tiav, xws li kev txhim kho lub zog ntawm cov stent.
