Ukukhetha imilomo yemilomo egumbini lokucoca uxinzelelo oluphezulu, kufuneka uqale uqonde uxinzelelo lokucoca. Xa uxinzelelo lwenkqubo yokutshiza lumiselwe, kuya kufuneka ukhethe ubume bokutshiza obufanelekileyo. Uhlobo lokuqala ngumlomo wekhowuni opheleleyo. Kukulungele ukusetyenziswa kwimeko apho umlomo kunye nento ekufuneka icociwe imile. Ngenxa yokuba inendawo enkulu yokugubungela kunye nesitshizi esifanayo, kungoko inokugubungela ngokupheleleyo into etshiziweyo, kodwa into engalunganga kumbhobho wecone opheleleyo kukuba ifuthe lincinci. Ngaphantsi kwenqanaba lokuhamba okufanayo, amandla empembelelo wombhobho othe tye okanye umbhobho wefeni ocaba kakhulu mkhulu kunombhobho wekhowuni opheleleyo. Kodwa ngenxa yempembelelo yamandla Ukuba ibango alikho phezulu kangako, umbhobho wekhowuni opheleleyo lolona khetho lufanelekileyo.

Ukhetho lwesibini ngumbhobho wefeni ethe tyaba, onokuthi uvelise ifuthe elikhulu kwaye ngowona ulungileyo ekucoceni umphezulu wento, kodwa isitshixo sefeni ethe tyaba nayo inezinto ezingalunganga, oko kukuthi, ulwalathiso lwento yokutshiza ilungisiwe, kwaye ukugubungela kuphela. Umgca othe tye, indawo engaphandle komgca othe ngqo ayinakugqunywa, kodwa ukuba into kufuneka icocwe kwaye nemilomo ishukuma ngokuhambelana, ke le ngxaki inokusonjululwa ngokugqibeleleyo.

Uhlobo lwesithathu lwemilomo luphandwe ngononophelo kwaye lwaphuhliswa sithi ukubuyekeza le miqathango mibini ingentla ngexesha elinye. Iqhutywa yinto enye okanye ezininzi ezijikelezayo ukujikeleza umlomo wombhobho weflethi ukufezekisa indawo enkulu yokugubungela. Nokuba umbhobho ofakiweyo ufakiwe Uphumle ngento, okanye unokugubungela umphezulu wesetyhula.

Ukuthengwa kwemilomo yeglasi yegumbi lokucoca ekhethekileyo, sinezinye izisombululo zoyilo. Sinethemba lokuba unganxibelelana nathi kwaye iinjineli zethu ziya kukunika eyona mpendulo ilungileyo.
