Tsav los ntawm kev lag luam nthwv dej, titanium thiab titanium alloys, hailed li 'tus huab tais ntawm biometals,' tab tom pib mus rau txoj kev dav dav ntawm kev siv hauv kev kho mob. Lawv ua tiav cov pob txha thiab cov ntaub so ntswg kev koom ua ke los ntawm biocompatibility zoo heev, dais thiab tiv thaiv lub cev nrog cov khoom siv kho tshuab zoo, thiab nyob ruaj khov nyob rau lub sijhawm nrog muaj zog corrosion kuj. Cov txiaj ntsig zoo no tsim lawv cov txiaj ntsig tseem ceeb ua cov ntaub ntawv kho mob siab heev. Txoj kev loj hlob ntawm titanium hauv kev kho mob yog hloov mus rau ntau dua precision, txawj ntse, thiab biomimicry.
1. 3D Printing (Additive Manufacturing) of Personalized Implants is the most disruptive trends. Raws li tus neeg mob cov ntaub ntawv CT, 3D luam ntawv tuaj yeem:
Customization: Tsim cov khoom cog cog uas zoo sib xws rau tus neeg mob tus qauv anatomical (xws li vertebrae thiab pelvic prostheses).
Porous Structure: Print implants with bio-mimetic microporous structures. Cov qauv no ua rau cov pob txha tshem tawm ntawm tib neeg cov pob txha, zoo heev txhawb cov pob txha ingrowth kom muaj kev ruaj ntseg ntau ntxiv, thaum ntxiv optimizing elastic modulus.
2. Kev hloov kho deg functionalization ua rau titanium implants 'smarter.'
Txhawb cov pob txha kev sib koom ua ke: Tsim cov txheej txheem bioactive tshiab (xws li cov txheej txheem uas muaj kev loj hlob zoo li BMP) txhawm rau ua kom cov txheej txheem kho kom zoo.
Tshuaj tua kab mob thiab tshuaj tiv thaiv- kis kab mob: Thauj qhov chaw nrog nyiaj ions, tshuaj tua kab mob, lossis siv cov tshuaj tua kab mob ntawm nanostructures lawv tus kheej los daws qhov kev sib tw ntawm cov kab mob tom qab- cog qoob loo.
3. Kev tsim kho tshiab
Titanium AlloysLow Elastic Modulus Alloys: Tsim - hom titanium alloys xws li Ti-Nb-Zr-Sn series, uas nws elastic modulus nyob ze rau ntawm tib neeg cov pob txha, uas muaj txiaj ntsig zoo rau cov pob txha noj qab haus huv.
Aluminium- thiab Vanadium- Cov Alloys Dawb: Txawm hais tias vanadium thiab txhuas muaj toxicity tsawg, tsim kom muaj kev nyab xeeb ntawm cov hlau sib xyaw (xws li Ti-6Al-7Nb lossis Ti-Zr alloys) yog lub hom phiaj mus sij hawm ntev.
