Disiki za Titanium zo Kwa muganga zo Gukoresha Meno – XINNUO

Mu Bushinwa, ‌1 kuri buri 4titanium yo mu rwego rw'ubuvuziImplants zikomoka kuri ‌Xinnuo‌. Uyu munsi, turabagezaho disiki zacu za titanium‌, ibikoresho by'ingenzi mu gukoresha ‌meno‌.

Incamake y'ibicuruzwa

Ubwoko: Iboneka mu buryo bw'uruziga n'ubwa kare.

Ibikoresho: Titanium y'umwimerere &aloyi ya titaniyumu.

Ibipimo bisanzwe: Disiki izengurutse: Ø98mm, ubugari bwa mm 10-25.

Disiki kare: 140×150mm, ubugari bwa 10-25mm.

Disiki za titaniyumu y'amenyo zabaye ibikoresho by'ingenzi mu bijyanye no gusana akanwa muri iki gihe bitewe n'imikorere yazo myiza. Iyi mashini yihariye ikozwe muri titaniyumu na aluminiyumu, vanadium n'ibindi bintu mu buryo buboneye, bigaragaza ibyiza bidasubirwaho mu guhuza imiterere y'umubiri, imbaraga za mekanike no kurwanya ingese.

Ikintu cyayo cy’ingenzi ni uko ihura neza n’ibintu byose. Agace ka okiside gakomeye kazagaragara ku buso bwa titaniyumu, bigatuma umubiri w’umuntu udashobora kwangwa. Iyi miterere igabanya cyane ibyago byo kubyimba hafi y’udusimba twatewe. Amakuru y’ubuvuzi agaragaza ko igipimo cy’imyaka icumi cyo kubaho kw’udusimba twa titaniyumu gishobora kugera ku kigero kirenga 95%, kirenze kure ibikoresho gakondo bya cobalt-chromium alloy.

Ku bijyanye n'imiterere ya mekanike, aloyi za titaniyumu zigaragaza igipimo gitangaje cy'imbaraga hagati y'uburemere. Ubucucike ni 60% gusa by'icyuma, ariko imbaraga zo gukurura zishobora kugera kuri 900MPa, kandi modulus yoroshye yegereye cyane inyama karemano z'amagufwa. Iyi miterere yirinda ingaruka zo "gukingira stress". Imiterere ifite ishusho ya disiki ikwiriye cyane cyane mu gukora uduce tw'implant, dushobora gukwirakwiza imbaraga zo kuruma no gukumira ko amagufwa asubirana. Ikoranabuhanga rya CNC rigezweho rishobora kuyitunganya ikayihindura imiterere yoroheje cyane ya 0.3mm mu gihe ikomeza kurwanya cyane imihindagurikire y'amagufwa.

Ubudahangarwa bw'ingufu nabwo buratangaje. Mu buryo bugoye bwo gushonga kw'amacandwe, igipimo cyayo cya ngura buri mwaka kiri munsi ya mm 0.001, ibi bikaba ari byiza cyane kurusha icyuma kidashonga. Nyuma yo gusiga amavuta, ubuso bushobora gukora amabara y'amabara atandukanye, ibyo bikaba byoroshye kumenya no gushyira mu mwanya wabwo mu gihe cyo kubaga kandi bigashobora kunoza ubwiza bw'amacandwe.

Ibyiza by'ikoranabuhanga ryo gutunganya ibintu ntibikwiye kwirengagizwa. Uburyo bwiza bwo gutunganya ibintu hamwe n'ubushyuhe buke bwa titaniyumu bituma itunganywa hakoreshejwe ikoranabuhanga rigezweho nko gukata laser no gukoresha electrospark machining. Sisitemu zigezweho za CAD / CAM zishobora kuyitunganya mu buryo bukozwe mu mashini ifite ubushobozi bwa 50μm. Ubu buso bufite imyenge butuma osteoblast ifatana kandi bukongera umuvuduko wo gufatana kw'amagufwa ku kigero cya 40%.

Ibikoresho bifite ubushobozi bwo guhuza amashusho neza cyane. Nta bikoresho bihari mu gihe cyo gusuzuma CT, kandi nta kwivanga kwa rukuruzi mu bidukikije bya MRI, bitanga ishingiro ryumvikana ry'ishusho nyuma yo kubagwa. Ni ngombwa kuvuga ko ingano yabyo yo kwaguka kw'ubushyuhe ihuye cyane na enamel karemano, ibyo bikaba birinda ko amazi asubira inyuma bitewe n'impinduka z'ubushyuhe.

Hakoreshejwe ikoranabuhanga ryo gucapa mu buryo bwa 3D, disiki za titaniyumu zishobora gukora implants zihariye zifite imiterere ya bionic trabecular. Iyi miterere mishya yongera ubushobozi bwo guhagarara bwa mbere ho 30% kandi ikagabanya igihe cyo gukira kugeza ku byumweru 3-4. Imiterere yo kurengera ibidukikije nayo iratangaje. Irashobora kongera gukoreshwa 100% kandi ijyanye n'igitekerezo cy'iterambere rirambye ry'ubuvuzi bwa none.
