Izixhoboluhlobo lwezixhobo ezingasetyenziswa kakhulu ebomini, nokuba zezomoya, ezokuthutha impahla, iimoto njalo njalo. Nangona kunjalo, xa izixhobo ziyilwe kwaye zicutshungulwa, kufuneka inani leegiya zazo. Ukuba zingaphantsi kweshumi elinesixhenxe, azikwazi ukujikeleza. Uyazi ukuba kutheni?
Okokuqala, isizathu sokuba iigiya zikwazi ukujikeleza kukuba kufuneka kubekho ubudlelwane obuhle bokudlulisa phakathi kwegiya ephezulu kunye negiya esezantsi. Kuphela xa unxibelelwano phakathi kwezi zimbini lukhona, apho ukusebenza kwazo kungaba lulwalamano oluzinzileyo. Ukuthatha iigiya ezingenanto njengomzekelo, iigiya ezimbini zinokudlala indima yazo kuphela ukuba zidibanisa kakuhle. Ngokukodwa, zahlulwe zibe ziintlobo ezimbini:izixhobo zokushukumisakwayeiigiya zehelical.
I-coefficient yokuphakama kwesihlomelo segiya ye-spur esemgangathweni yi-1, i-coefficient yokuphakama kwe-dedendum yi-1.25, kwaye iqondo le-engile yoxinzelelo lwayo kufuneka lifikelele kuma-20 degrees. Ziigiya ezimbini ezifanayo.
Ukuba inani lamazinyo e-embryo lingaphantsi kwexabiso elithile, kuya kugrunjwa inxalenye yengcambu yengcambu yamazinyo, ebizwa ngokuba yi-undercutting. Ukuba i-undercut incinci, iya kuchaphazela amandla kunye nokuzinza kwegiya. Ezilishumi elinesixhenxe ezikhankanyiweyo apha zenzelweizixhobo.
Ukongeza, ishumi elinesixhenxe linani eliphambili, oko kukuthi, inani lokudibana phakathi kwezinyo elithile legiya kunye nezinye iigiya lincinci phantsi kwenani elithile lokujika, kwaye aliyi kuhlala kweli nqanaba ixesha elide xa amandla esetyenziswa. Iigiya zizixhobo zokuchaneka. Nangona kuya kubakho iimpazamo kwigiya nganye, amathuba okuguguleka kweshaft yevili kwiSeventeen aphezulu kakhulu, ngoko ke ukuba yiSeventeen, kuya kulunga ixesha elifutshane, kodwa akuyi kusebenza ixesha elide.
