Dental Vitallium yog ib qho tshwj xeeb cobalt -chromium- molybdenum (Co-Cr-Mo) alloy uas ua lub luag haujlwm tseem ceeb hauv prosthodontics, feem ntau yog siv los tsim cov qauv ruaj khov rau kev tshem tawm ib feem ntawm cov hniav cuav (RPDs), kho hniav kho hniav, thiab implant- txhawb nqa rov qab. Nws cov tshuaj lom neeg muaj pes tsawg leeg ua rau nws muaj cov khoom tshwj xeeb: lub zog tensile siab ua rau nws tuaj yeem tiv taus lub zog masticatory ntau tau tsim los ntawm kev zom txhua hnub, tiv thaiv kev deformation lossis tawg ntawm kev siv ntev.
Qhov tseem ceeb, nws nthuav tawm cov kev tiv thaiv corrosion zoo tshaj, tiv thaiv lub qhov ncauj hnyav ib puag ncig- suav nrog cov qaub ncaug, cov khoom noj khoom haus khib nyiab, thiab cov kab mob ua haujlwm - yog li txuas ntxiv lub hauv paus kev pab cuam lub neej. Nws zoo heev biocompatibility txo qhov tsis zoo tshwm sim, xws li cov lus teb tsis haum lossis cov tawv nqaij mos khaus, uas yog qhov tseem ceeb rau ntev - lub qhov ncauj kam rau ua.
Vitallium moj khaum tawm tsam qhov zoo tshaj plaws sib npaug ntawm lub zog thiab lub teeb yuag, ua kom cov neeg mob kev nplij siab yam tsis muaj kev cuam tshuam cov qauv kev ncaj ncees. Lawv muab lub hauv paus ruaj khov rau acrylic lossis porcelain hniav hniav, txo qhov kev pheej hmoo ntawm chipping lossis loosening. Thaum lub sij hawm fabrication, lub alloy tswj qhov seem stability nyob rau hauv ob qho tib si casting thiab milling txheej txheem, tso cai rau kom meej adaptation rau edentulous ridges thiab abutment hniav, uas txhim khu kev tuav thiab txo cov nqaij mos tsis xis nyob. Piv nrog rau cov nickel ib txwm siv-chromium alloys, Vitallium muaj kev ua haujlwm zoo dua thiab biocompatibility, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev kho hniav ntev ntev - kho hniav nyob rau hauv ntau yam kev siv tshuaj kho mob.
