Izixhobo Endodontic. Inkcazelo iintlobo ezahlukeneyo

izixhobo Endodontic esetyenziselwa zazo amazinyo em- kwaye ingcambu nemijelo ze yezinyo laso. Oku izixhobo ezikhethekileyo ukususela ngentsimbi carbon okanye nickel-titanium ingxubevange. Kubalulekile ukuphawula ukuba izixhobo ezenziwe nickel-titanium ingxubevange, bhetyebhetye kakhulu, abe phezulu ekhuselekileyo kunye "imilo memory". Bona eyenziwe olungenanto icandelo elijekelezayo esiphambanweni ukulisika zisetyenziswa nesezantsi isantya ezizodwa ngokumba kunye nomsebenzi wezandla. Kuba lula koogqirha zonke izixhobo endodontic babe encoding zabo ezizodwa. Iikhowudi ziza ngeendlela ezininzi.

Iikhowudi yamanani ziyasetyenziswa ngqo emphinini (kwi izixhobo ngesandla) okanye kumqulu (yosebenziso drill). inani ngalinye netoti apho obubonakaliswa hundredths le ndlela.

ikhowudi Geometric (ephotheneyo, isikwere, unxantathu, octagon, isangqa) ibonisa a umnqamlezo-icandelo yenxenye ukusebenza.

ikhowudi Umbala iquka imibala ezintathu eliphakathi kwaye ezintandathu ezinkulu. Umbala libhekisela resolution isixhobo. Ngexesha unyango emisele ugqirha kufuneka ndiphoswe umbala omnye.

Izixhobo eziyilelwe lo msebenzi manual, unako ukumelana ubushushu ukuya ku ezimakhulu mabini degrees Celsius. Ziqulethe uluhlu handle ofunekayo zejometri, kwaye wedijithali umbala iibhakhowudi, yaye inxalenye ukusebenza abaqhagamshelwe ngentonga. Intonga linobude-21 ukuya kwi-31 mm kunye inxalenye ukusebenza usoloko ubude-16 mm. isixhobo ngasinye ngesiciko abicah. Yena igugile ngqo kwi intonga kwaye icala okungafani, nto leyo ebonisa bend lweqela.

izixhobo Endodontic ukuze zisetyenziswe imisele iingcambu zezi:

1. Kuba extirpation le yintlama. Isixhobo ikhangeleka ngathi rasp, kwaye amazinyo. Amazinyo babe ukuhamba ephantsi, ubungakanani babo ungaphantsi kwe kabini ubukhulu ngentonga. Xa isixhobo egxile ingcambu emjelweni, amazinyo acofiweyo kwizikhondo, kwaye xa ayinakolulwa ukhipha kunye zomzimba capture ido- okanye detritus. Kukho imilinganiso ezisixhenxe esi sixhobo.

2. Ukuze ubone ubunzulu misele ingcambu kusetyenziswa inaliti. Ezi nkundla ke zenzelwe ukuba kufunyaniswe ngobungakanani lomnqamlezo-channels. Iinaliti kuza ngokobungakanani ezintlanu.

3. Ukwandisa umlomo umjelo, sebenzisa olwandisa ekhethekileyo, oko onenxalenye ukusebenza drop-. Loo isixhobo ifumaneka nge milinganiselo-yecandelo ezintandathu.

4. Ukwenzela ukuba kwandiswe misele emxinwa egosogoso, ukusebenzisa izixhobo ezikhethekileyo endodontic efana rasp. Le ibandakanya izixhobo ezisixhenxe a ubude 25 intonga mm. Phezu wobuso kukho amashumi amahlanu amazinyo, leyo zicwangciswe ukuba esqwini isixhobo kwi-engile. Ubude kwamazinyo-phindwe kathathu incinane ubukhulu isixhobo. incam kwamazinyo ngokulula bahambe ijelo.

izixhobo bokushicilela yamazinyo, ezenziwe i intsila nickel kunye titanium, abe Taper enkulu. Ngoko ke, lo sangqa emva ngamnye ngakumbi ku 290/0. Oku kuvumela ukwanda uniform kwingcambu lomsele. imiphetho ajikelezayo kunye nefom iinkalo ukuthintela jamming zesixhobo. incam blunt ikuvumela ukuba ukubamba isixhobo kwicala umjelo nokuba kwindawo amajiko enkulu, singabi ukudalwa izitulo kunye perforation. ubukhulu zabo ukusuka 15 N ukuya 150 N.

Sebenzisa endodontics izixhobo ezichazwe apha ngentla, kwakunye izixhobo ezikhethekileyo - condensers ukusikwa ezikhethekileyo ezijikeleze-ezimile.
