The Endo Z Bur musanganiswa wedenderedzwa uye koni-yakaumbwa coarse bur inopa mukana wekupinda mukamuri yepulp uye kamuri madziro ekugadzirira mukuvhiya kumwe chete. Izvi zvinogoneka neiyo bur yakasarudzika dhizaini, iyo inosanganisa denderedzwa uye koni.

◇◇Ndeapi mabasa avanoshandira ◇◇

1. Iyo carbide bur ine magumo akachengeteka ayo akaderedzwa uye akatenderedzwa kubva. Yakakurumbira nekuti magumo asina kucheka anogona kuiswa zvakananga pa pulpal pasi pasina njodzi yekubaya zino. Paunenge uchishanda pamadziro emukati axial, iyo lateral yekucheka mipendero yeEndo Z bur inoshandiswa kupisa, kupfava, uye kunatsa pamusoro.

   Mushure mekutanga kupinda, iyi yakareba, tapered bur ichapa aperture muchimiro chefunnel, iyo inobvumira kupinda mukamuri ye pulp. Nemhaka yokuti haicheki, muromo wakagomara unodzivirira chiridzwa kuti chisapinde pauriri hwekamuri repasi kana madziro emudzi wegero. Kureba kwenzvimbo yekucheka ndeye 9 millimeters, nepo kureba kwese kuri 21 millimeters.

◇◇Iyo Endo Z Burs inoshanda sei chaizvo ◇◇

Mushure mekunge imba yepulp yawedzerwa uye yakavhurwa, bur inofanirwa kuiswa mugomba rakagadzirwa. Iyi nhanho inouya mushure mekuvhurwa kwe pulp chamber.

Iyo isiri - yekucheka tipi inofanirwa kubatwa yakatarisana nepasi pekamuri yemukati, uye kana bur rasvika pamadziro ekamuri, rinofanira kumira kucheka. Chinangwa cheizvi ndechekuita kuti maitiro ekuramba kupinda awedzere kupusa.

Cherechedza: Izvi zvinongoshanda kune mazino ane nhamba yakakosha yemidzi. Izvo zvichiri kugona kuishandisa mumeno ane canal imwe chete, asi hapana apical pressure inofanirwa kushandiswa mukati mekuita.

Uye Caries akapararira mupulp nyanga kana mugomba rinopa mukana kune pulp nyanga.

Mushure meizvozvo, iyo endo Z bur inopinzwa mugomba.

Iyo bur inofambiswa pasi pepuru pasi nedhiraivha dhiraivha, zvisinei, inomira kucheka kana ikasangana nemadziro.

Kana kona yebur ikasatariswa, kugadzirira kuchave kwapera - tapered, uye yakawandisa zino ichabviswa.

Nekudaro, kana uchigadzira iyo workpiece, iyo bur inofanirwa kubatwa yakafanana neiyo axis refu yezino. Iyo bur's tapered nature inoburitsa optimally tapered yekupinda. Kana yakanyatso chengetedza, yakamanikana kupinda ichidikanwa, parallel - mativi edhaimani bhura kana Endo Z bhura rinoiswa pakona yakarerekera kupakati pegomba rinogona kugadzira yakatetepa prep.
