Ua ntej tshaj plaws, qhov laj thawj uas cov iav tuaj yeem tig tau yog vim tias yuav tsum muaj kev sib raug zoo ntawm cov iav sab saud thiab cov iav qis. Tsuas yog thaum muaj kev sib txuas ntawm ob qho tib si, nws thiaj li ua haujlwm tau ruaj khov. Piv txwv li, siv cov iav tsis sib haum, ob lub iav tsuas yog ua tau lawv lub luag haujlwm yog tias lawv sib haum zoo. Tshwj xeeb, lawv muab faib ua ob hom:cov iav spurthiabcov iav helical.
Tus coefficient ntawm qhov siab ntawm qhov ntxiv ntawm tus qauv spur iav yog 1, tus coefficient ntawm qhov siab ntawm dedendum yog 1.25, thiab qib ntawm nws lub kaum sab xis yuav tsum ncav cuag 20 degrees. Nws yog tib ob lub iav.
Yog tias tus naj npawb ntawm cov hniav ntawm lub embryo tsawg dua qee tus nqi, ib feem ntawm cov hauv paus hniav yuav raug khawb tawm, uas hu ua undercutting. Yog tias qhov undercut me me, nws yuav cuam tshuam rau lub zog thiab kev ruaj khov ntawm lub iav. Kaum xya uas tau hais ntawm no yog raucov iav.
Ntxiv rau, kaum xya yog tus lej tseem ceeb, uas yog hais tias, tus lej ntawm kev sib tshooj ntawm ib qho hniav ntawm lub iav thiab lwm lub iav yog qhov tsawg tshaj plaws nyob rau hauv qee qhov kev tig, thiab nws yuav tsis nyob ntawm lub sijhawm no ntev thaum lub zog siv. Cov iav yog cov cuab yeej precision. Txawm hais tias yuav muaj qhov yuam kev ntawm txhua lub iav, qhov tshwm sim ntawm lub log ncej hnav ntawm kaum xya yog siab dhau, yog li ntawd yog tias nws yog kaum xya, nws yuav zoo rau lub sijhawm luv luv, tab sis nws yuav tsis ua haujlwm rau lub sijhawm ntev.
