Iimveliso kwicandelo lezonyango zinemiqathango engqongqo yomgangatho, kwaye izinga lolawulo lomgangatho kwinkqubo yemveliso liya kuchaphazela ngqo impembelelo yezonyango. Njengoko izixhobo zonyango zisiba nobuchule ngakumbi nangakumbi, oomatshini bokulinganisa ividiyo baye baba yinto ebalulekileyo. Idlala yiphi indima kushishino lwezonyango?
Ngokungafaniyo neemveliso eziqhelekileyo, izixhobo zonyango kunye nezixhobo zonyango zinempembelelo ethe ngqo kwimpilo yabantu, ngoko ke umgangatho kufuneka ulawulwe ngokungqongqo. Ngaphezu koko, izixhobo ezininzi kushishino lwezixhobo zonyango zincinci kakhulu ngobukhulu, zithambile kwaye zicacile ngezinto kwaye zintsonkothile ngesimo. Umzekelo: ii-stents zemithambo yegazi ezingenelelayo kunye neemveliso ze-catheter, ezithambileyo ngobume bazo kwaye zincinci kwaye zicacile; iimveliso zezinzipho zethambo zincinci kakhulu ngesimo; inxalenye ye-occlusal yamazinyo okufakelwa ayincinci nje kuphela kodwa ikwantsonkothile ngesimo; imveliso egqityiweyo yelungu lethambo elenziweyo ifuna uburhabaxa bomphezulu. Ingqongqo njalo njalo, zonke zineemfuno zokulinganisa ngokuchanekileyo.
Ukuba sisebenzisa izixhobo zokulinganisa uqhagamshelwano zemveli, kuya kuba nzima ukufezekisa umlinganiselo ochanekileyo wezi mveliso, ngoko ke umatshini wokulinganisa ividiyo osebenzisa imifanekiso ye-optical ukulinganisa okungekuko uqhagamshelwano uye waba sisixhobo sokulinganisa esibalulekileyo kwishishini lezonyango. Umatshini wokulinganisa ividiyo kaChengli uqaphela ukuchongwa ngokuchanekileyo kobukhulu be-workpiece, i-engile, indawo kunye nezinye iindlela zokunyamezelana kwejometri ngokusebenzisa ubuchwepheshe bokulinganisa umfanekiso we-optical. Ngenxa yokuba kusetyenziswa ubuchwepheshe be-optical, umlinganiselo unokwenziwa ngaphandle kokuchukumisa i-workpiece ngexesha lokulinganisa. Unezibonelelo ezikhethekileyo ze-workpiece ezincinci, ezincinci, ezithambileyo kunye nezinye izinto eziguquguquka lula ezingafanelekanga ukuvavanywa ngezixhobo zokulinganisa uqhagamshelwano.
Umatshini wokulinganisa ividiyo unokusombulula ngempumelelo ukufunyanwa kwezinto ezincinci, ezincinci, ezithambileyo nezinye izinto zokusebenza kwishishini lezixhobo zonyango, kwaye unokufikelela ekulinganisweni okusebenzayo kwe-contour, imo yomphezulu, ubungakanani, kunye nendawo ye-engile yezinto ezahlukeneyo zokusebenza ezintsonkothileyo, kwaye ukuchaneka kokulinganisa nako kuphezulu kakhulu. Umgangatho wezixhobo zonyango uphuculwe ngokwemigangatho. Kwakhona sisixhobo sokulinganisa esinokwenza uvavanyo lobunzima kwiintlobo ezahlukeneyo zezinto zokusebenza, kwaye siphucule ngcono ukusebenza kokulinganisa.
