Ma Diski a Titanium Zamankhwala Ogwiritsa Ntchito Zamano - XINNUO

Ku China, 1 mwa 4 aliwonsetitaniyamu wamankhwalama implants amachokera ku Xinuo. Masiku ano, tikuwonetsa ma disks athu a titaniyamu, zomwe ndizofunikira kwambiri pakugwiritsa ntchito mano.

Chidule cha Zamalonda

Mitundu: Imapezeka mozungulira komanso masikweya.

Zida: Titaniyamu yoyera &titaniyamu aloyi.

Zofunika Kwambiri: Chimbale Chozungulira: Ø98mm, makulidwe 10-25mm.

Diski ya Square: 140 × 150mm, makulidwe 10-25mm.

Mano a titaniyamu aloyi zimbale akhala mfundo yaikulu m'munda wa masiku ano kubwezeretsa m'kamwa chifukwa cha ntchito yawo yabwino. Aloyi yapaderayi imapangidwa ndi titaniyamu yoyera kwambiri ndi aluminiyamu, vanadium ndi zinthu zina mu chiŵerengero cholondola, kusonyeza ubwino wosasinthika mu biocompatibility, mphamvu zamakina ndi kukana dzimbiri.

Chochititsa chidwi kwambiri ndi biocompatibility yake yomwe ili pafupi kwambiri. Kanema wandiweyani wa oxide amangopanga pamwamba pa aloyi ya titaniyamu, zomwe zimapangitsa kuti minofu yamunthu isamakane kukanidwa. Izi zimachepetsa kwambiri chiopsezo cha kutupa kuzungulira ma implants. Zambiri zachipatala zikuwonetsa kuti kupulumuka kwazaka khumi kwa ma implants a titaniyamu kumatha kufika kupitilira 95%, kupitilira zida zachikhalidwe za cobalt-chromium alloy.

Pankhani yamakina, ma aloyi a titaniyamu amawonetsa kuchuluka kodabwitsa kwa mphamvu ndi kulemera. Kachulukidwe ndi 60% yokha ya chitsulo, koma kulimba kwamphamvu kumatha kufika kupitilira 900MPa, ndipo zotanuka modulus zili pafupi ndi minyewa yamafupa achilengedwe. Izi zimapewa bwino "stress shielding". Mapangidwe opangidwa ndi diski ndi oyenera kupanga ma implant abutments, omwe amatha kugawanitsa mphamvu yoluma ndikuletsa kufalikira kwa mafupa. Ukadaulo waukadaulo wa Precision CNC ukhoza kuwusintha kukhala wowonda kwambiri wa 0.3mm ndikusunga kukana kwabwino kwambiri.

Kukaniza kwa dzimbiri ndikodabwitsanso. M'malo ovuta a electrolyte a malovu, chiwombankhanga chake pachaka chimakhala chochepera 0.001mm, chomwe chili bwino kwambiri kuposa chitsulo chosapanga dzimbiri. Pambuyo anodizing, pamwamba akhoza kupanga mitundu kusokoneza mitundu, amene ndi yabwino chizindikiritso ndi malo pa opaleshoni ndipo akhoza kusintha kukongola.

The processing teknoloji ubwino sayenera kunyalanyazidwa. Pulasitiki yabwino kwambiri komanso kutsika kwamafuta a titaniyamu alloy kumathandizira kuti isinthidwe ndiukadaulo wopanga bwino monga kudula kwa laser ndi electrospark Machining. Machitidwe amakono a CAD/CAM amatha kuyipanga kukhala mawonekedwe a microporous ndi kulondola kwa 50μm. Izi porous pamwamba amalimbikitsa osteoblast ubwenzi ndi kumawonjezera fupa kugwirizana liwiro ndi 40%.

Zinthuzi zimakhalanso ndi mawonekedwe abwino kwambiri azithunzi. Pafupifupi palibe zinthu zakale pakuwunika kwa CT, ndipo palibe kusokoneza kwa maginito m'malo a MRI, zomwe zimapereka chithunzi chomveka bwino pakuwunika pambuyo pa opaleshoni. Ndikoyenera kutchula kuti coefficient yake yowonjezera kutentha imagwirizana kwambiri ndi enamel yachilengedwe, yomwe imapewa bwino microleakage ya kubwezeretsa chifukwa cha kusintha kwa kutentha.

Pogwiritsa ntchito ukadaulo wosindikiza wa 3D, ma disks a titaniyamu alloy tsopano atha kupanga ma implants omwe ali ndi zida za bionic trabecular. Kukonzekera kwatsopano kumeneku kumawonjezera kukhazikika koyambirira ndi 30% ndikufupikitsa nthawi ya machiritso mpaka masabata 3-4. Makhalidwe oteteza zachilengedwe ndiwonso apamwamba. Ndi 100% yobwezeretsanso ndipo imagwirizana ndi lingaliro lachitukuko chokhazikika chamankhwala amakono.
