Hlau thav duab ib nrab nrog Acetal Hook

Tus qauv thiab cov ntaub ntawv

Hlau thav duab ib nrab nrog Acetal Hooks ua ke aLub moj khaum nruj hlau(piv txwv li, cobalt - chromium lossis titanium) rau cov qauv kev ruaj ntseg nrogHniav - xim acetal resin hooks(Polyoxymethylene). Lub hauv paus hlau ua kom muaj cov hniav ploj, thaum acetal hooks {} milled ntawm cad / cam rau kev sib xyaw nrog ntuj kho hniav.

Cov ntsiab lus tseem ceeb

Kev ua kom zoo nkauj: Acetal cov hniav {{0} zoo li HEE tshem tawm cov claspasts ntawm cov nplaum hlau, thov rau cov tsos mob-} Cov neeg mob.

Kev ua yam ua hauj: {-}}}}}}}}}}}}}}}}}}}}}}}}}}} eclexible acetal hooks ruaj khov ntawm abutment hniav kev ntxub ntxaug yam tsis muaj kev puas tsuaj rau cov hniav.

Yam ruaj khov: Acetal Resin muaj lub zog tensile lub zog (90 MPa), hnav tsis kam, thiab seem ruaj khov, kav ntau xyoo nrog kev tu kom zoo.

Nplij siab: Nyias, lub teeb yuag txo kev cuam tshuam qhov ncauj, thaum lub moj khaum hlau sib faib tau cheat ua kom yuam kev.

Cov Ntawv Thov Kev Kho Mob

Zoo tagnrho rauIb nrab Npuag PoobCov neeg mob ib nrab, cov neeg mob no xav tau kom muaj kev cia siab nrog tsawg heev. Lawv ua haujlwm zoo rau ob qho tib si anterior (pem hauv ntej) thiab posterior (rov qab) kho dua tshiab, tshwj xeeb yog thaum muaj kev ua kom zoo nkauj.

Saib Xyuas & Txij Nkawm

Ntxuav txhua hnub nrog txhuam txhuam hniav thiab tsis - Abrasive Muab tshuaj txhuam. Tsis txhob muaj dej kub (los tiv thaiv acetal warping) thiab khaws cia hauv rooj plaub tiv thaiv. Kev kuaj hniav tsis tu ncua- UPS ua kom ntseeg tau tias qhov zoo tshaj plaws thiab kev ua siab ntev.

Yuav ua li cas Acetal Resin Hooks sib piv rau cobalt - chromium clasps hauv kev khaws cia hauv kev tuav thiab lub siab ntev?

1. Khaws

Cobalt - chromium clasps: Kev tuav thawj zaug yog qhov muaj zog dua, tab sis nws ploj mus nyob ib zaug (piv txwv li, tom qab 700-800 qhov kev tso siab / tshem tawm) vim yog kev qaug hlau.

Acetal Resin Hooks: Pib rov qab yog tsawg zog, tab sis nws nyob qis zog rau ntev dua (3-4 xyoos). Lawv kuj yog hniav - xim, yog li muaj kev zoo nkauj ntxiv.

2. Lub Neej

Cobalt - chromium clasps: Tiv thaiv cov chewing hnyav thiab hnav zoo (kawg 8-10 xyoo), tab sis hlau rog tuaj yeem ua rau muaj kev tawm tsam sijhawm.

Acetal Resin Hooks: Stable and corrosion-resistant (last 5–7 years) but sensitive to heat (hot water >60℃Warps lawv tsis muaj qhov cuam tshuam).

Nyob rau hauv luv luv: Xaiv Cobalt - chromium rau kev pib ua kom muaj zog, piv txwv li cov hniav rov qab ntev dua); Xaiv acetal rau ntev {{}}} kawg retention thiab zoo dua zoo li (piv txwv li cov hniav).
