Biocompatibility ntawm Titanium Alloys

Ua ntej, lub ntuj tsim titanium dioxide zaj duab xis (tsuas yog ob peb nanometers tuab) ntawm lawv qhov chaw tuaj yeem cais tawm cov hlau ions zoo thiab tuaj yeem tiv thaiv kev tiv thaiv kab mob.Meanwhile nws kuj muaj cov tshuaj inertness ruaj khov. Thib ob, lub elastic modulus ntawm titanium alloys (piv txwv li, Ti-6Al-4V kwv yees li 110 GPa) zoo sib xws ntawm tib neeg cov pob txha (10-40 GPa), thiab tuaj yeem txo qhov "kev ntxhov siab tiv thaiv" cov nyhuv thiab txhawb kev osseointegration. Tsis tas li ntawd, titanium alloys yog non-toxic thiab non-allergenic, yuav tsis tso cov tshuaj phem los yog ua rau muaj kev tsis haum tshuaj.so nws muab kev ruaj ntseg lav rau kev cog qoob loo mus ntev.

Ua ntej, lawv tuaj yeem loj hlob ua ke nrog cov pob txha (osteogenesis); thib ob, lawv tsis ua kom puas hlwb thiab biocompatible; thiab thib peb, lawv tuaj yeem tswj cov lus teb tiv thaiv kab mob thiab txo qis kev tsis lees paub (immunomodulation). Qhov no tso cai rau lawv siv kom ruaj khov thiab nyab xeeb hauv tib neeg lub cev, piv txwv li, hauv kev sib koom tes lossis kev cog hniav.

Cov txheej siv tib yam hydroxyapatite li pob txha, uas ua rau cov pob txha loj hlob sai; qhov saum npoo yog tsim rau hauv nanopores, ua kom yooj yim rau cov hlwb txuas; thiab nrog ntxiv ntawm cov pob txha loj hlob protein, cov hlwb mloog lus los ua cov pob txha hlwb.

Nws yog tam sim no siv rau hauv pob qij txha, pob txha screws, kho hniav, thiab pacemaker shells, pab tib neeg taug kev, noj, thiab muaj lub plawv dhia dua. Nyob rau hauv lub neej yav tom ntej, peb yuav tsim tshiab, softer, thiab ntau tib neeg- cov phooj ywg alloys uas tsis siv txhuas thiab vanadium; 3D luam ntawv yuav tso cai rau kev cog qoob loo kom haum rau koj cov pob txha; thiab ua ke nrog ceramics thiab plastics yuav tau txais txiaj ntsig zoo dua.
