Ndodo Yamano ya Titanium - Msana Wolondola Wamano Opangira Mano Amakono

Mu implantology ya mano, ndodo ndiye poyambira - koma si ndodo zonse zomwe zimapangidwa mofanana.
Kaya mukupanga makonda, zomangira zochiritsa, kapena titaniyamu yathunthu, zomwe mumasankha zimakhudza mwachindunji:
Kulondola koyenera - mipata yam'mphepete yoyezedwa mu ma microns
Kutopa kwanthawi yayitali - kukana kusinthasintha kwa masticatory kwazaka zambiri
Ubwino wapamtunda - mawonekedwe pakati pa chitsulo, gingiva, ndi fupa
Kutsata malamulo - FDA 510(k), chizindikiro cha CE, ndi ISO 13485 audits
Ndodo ya mano ya titaniyamu si chinthu chamtengo wapatali. Ndilolowetsamo mwaukadaulo.
Kodi Ndodo ya Dental Titanium N'chiyani?
Ndodo ya mano titaniyamundi malo olondola, cylindrical bar stock omwe amagwiritsidwa ntchito popanga subtractive (CNC kutembenuka, mphero, ndi Swiss Machining) kupanga:
Custom CAD/CAM abutments (titaniyamu maziko)
Machiritso abutments ndi machiritso zomangira
Implant ma analogi ndi kutumiza nsanamira
Zida zoyikira kwakanthawi (TADs / orthodontic mini-implants)
Malangizo opangira opaleshoni (opangidwa ndi ndodo, amagwiritsidwa ntchito ngati manja kapena zokopa)
Custom abutment screws ndi mapini posungira
Miyeso, kalasi yazinthu, ndi kumalizidwa kwapamwamba sizingochitika zokha - zimatsatiridwa ndi gawo lomaliza komanso momwe amapangira.
Maphunziro a Zakuthupi: Kalasi 2 vs. Sitandade 5 - Zomwe Labu Imafunikiradi
Mitundu iwiri ya titaniyamu imayang'anira ntchito zamano:
Gulu 2 (Commercially Pure - ASTM F67) imapangidwa ndi titaniyamu yopitilira 99% yokhala ndi okosijeni pakati pa 0.18% ndi 0.25%. Amapereka mphamvu zamakokedwe zosachepera 345 MPa, zokolola mphamvu zosachepera 275 MPa, kutalika kwa 20% kapena kupitilira apo, ndi kuuma mpaka 200 HV. Ubwino wachipatala wa Giredi 2 ndizovuta kwambiri, kukana kwa dzimbiri, komanso kukhululuka kwake. Ndodo za giredi 2 zimasankhidwa kuti zichiritse, zosinthira, ndi ntchito zosanyamula katundu pomwe zinthuzo siziyenera kuwononga ulusi wotsutsana kapena mawonekedwe osalimba. Ma Lab amasankha Giredi 2 pazovala zake zotsika za zida, mapangidwe a chip omwe angadziwike, komanso kukonza zenera lomwe lili bwino pamamilandu apamwamba kwambiri.
Gulu la 5 (Ti-6Al-4V ELI - ASTM F136) lili ndi 6% aluminiyamu ndi 4% vanadium yokhala ndi mpweya wokwanira 0.13% pamlingo waukulu. Imapereka mphamvu zolimba za 860 mpaka 965 MPa, zokolola za 795 mpaka 830 MPa, kutalika kwa 10% kapena kupitirira apo, ndi kuuma mpaka 350 HV. Phindu lachipatala la Gulu la 5 ndilofanana ndi mphamvu za 2.5 nthawi zambiri poyerekeza ndi Gulu la 2. Kufotokozera kwa ELI (Extra Low Interstitial) kumatsimikizira kuti ductility ndi fracture toughness for high-strong alloy alloy-yofunika kwambiri kwa khoma lopyapyala ndi makulidwe a khoma pansi pa 0.5 mm ndi mipiringidzo yautali yotalikirapo yomwe iyenera kupirira kulephera kwa fatiic. Ma Lab amasankha Giredi 5 chifukwa imathandizira mapangidwe osakira pang'ono, amachepetsa kuchuluka kwa zinthu kwinaku akukhalabe ndi mphamvu, ndipo amakwaniritsa zomwe amayembekeza pamakina opangira zida zoyambira.
Kodi Lab Lab Anu Ayenera Kuyika Gulu Lanji?
Kusankha koyenera kumadalira ntchito yeniyeni. Pamachiritso ochiritsira komanso kusamutsa, Gawo 2 likulimbikitsidwa. Kwa maziko a titaniyamu akorona amodzi okhala ndi makulidwe a khoma, mwina Gulu 2 kapena Gulu 5 angagwiritsidwe ntchito. Pamipanda yopyapyala yokongola yokhala ndi khoma pansi pa 0.5 mm, Gawo 5 likufunika. Pamipiringidzo yathunthu monga kukonzanso kwa All-on-4 ndi All-on-6, Gulu la 5 ndiye chisankho chomwe mumakonda. Kwa zomangira zomangira, Gulu la 5 ndilovomerezeka. Kwa manja ndi maupangiri opangira opaleshoni, Gulu la 2 ndilokwanira.
Ma labu okhazikitsidwa ambiri amakhala ndi magiredi 2 anthawi zonse, milandu yotsika mtengo komanso Giredi 5 pakubwezeretsa kwamtengo wapatali, kupsinjika kwambiri.
Miyezo Itatu Yofunikira ya Ndodo Yabwino
1. Kulekerera kwa Diameter - Maziko a Fit
Ndodo yomwe ndi 0.02 mm yokulirapo imakulitsa kukana, kufulumizitsa kuvala kwa zida, kutulutsa kutentha kwambiri, kuyika kusintha kwapang'onopang'ono, ndikuchepetsa kulondola kwamalo mu CNC lathe yanu.
