BrotSep 1: Kev Tshawb Fawb Ua Ntej
Use a hand chain (such as C-type pioneer file, K chain, H chain) to preliminarily explore the root canal orifice and determine the root canal length, curvature and calcification. Maj mam siv tes chains tsis muaj. 8, tsis muaj}}}}}}}}}}}}}}} . 15}
Ostep 2: Tsim cov channel ncaj
Thaum lub hauv paus canal tau lees paub kom tsis txhob muaj kev tsis pom zoo, siv sijhawm kom ceev, tsis txhob qhib lub hauv paus ncaj, tsis yog ntau tshaj li ob- peb feem ntau.
📏step 3: Qhov tseeb ua haujlwm ntev
Siv cov ntaub ntawv dredging (ceev), torque 1.5) thiab siv cov txheej txheem Lifting nrog lub cev muaj zog los ntxuav cov haujlwm ntev. Tom qab ntawd siv lub hauv paus canal ntsuas ntsuas nrog cov ntaub ntawv dredging los ntsuas cov lej tseeb.
ÇSTEP 4: CALAL CANAL SUAB
Siv cov saw hlau (xws li 04/20, 06/25, Ceev 400, Torque 400, torque 3.5) kom maj nthuav cov kwj dej hauv paus. Thaum ua haujlwm, tseem siv cov txheej txheem Lifting, nqa txhua 1 txog 2 hli rau pem hauv ntej, thiab txhua daim duab ua ntej tuaj yeem ua tiav tom qab 3 txog 5 zaug ntawm kev nqa ntawm nruab nrab. Thaum siv cov gutta - perchas uas phim tus qauv taper ntawm cov shaping saw siv kawg.
Kev tawm tswv yim:
Tag nrho cov canal kev kho mob yuav tsum tau nrog cov ntaub ntawv qhia txog tes (xws li c - hom cov pioner cov ntaub ntawv, k cov ntaub ntawv, thiab h files). Yog pom tias tus kwj dej hauv paus pom tau thaiv, tshuab cov ntaub ntawv yuav tsum tsis txhob siv. Cov ntaub ntawv siv tes yuav tsum tau siv nrog ultrasound kom maj qhib up lub calcified root canal. Cov ntaub ntawv siv tshuab tsuas siv tau tom qab lub hauv paus canal yog tsis txhim kho, thiab txhua txhua hloov ntawm cov kwj dej tom qab yuav tsum tau muab cov kwj dej loj los txo cov khib nyiab.
