Amathrendi Okuthuthukiswa Kwezigayi
Ama-grinders abambe iqhaza elibalulekile emkhakheni wokunakekelwa kwamazinyo iminyaka eminingi, asetshenziselwa ukususa amanani amancane oqweqwe lwamazinyo ukuze alolonge noma enze izitho zamazinyo. Kodwa-ke, ngokuthuthuka kwezobuchwepheshe bamazinyo kanye nesidingo esikhulayo sokwelashwa kwamazinyo okunembe kakhudlwana, okusebenzayo nokunethezekile, imboni yokugaya amazinyo ibone izinguquko ezinkulu eminyakeni yamuva nje.
Enye yezindlela zakamuva zokugaya amazinyo ukuthuthukiswa yobuchwepheshe be-CAD kanye ne-CAM, okuvumela ochwepheshe bamazinyo ukuthi baklame futhi benze ama-prosthetics ayinkimbinkimbi ngokushesha nangokunembile. Njengoba bengakha amamodeli e-3D ezinto zokufakelwa zamazinyo, ezingase zigaywe ngokuqondile noma ziphrintwe.
Omunye umkhuba emakethe yokugaya amazinyo ukwanda kokwamukelwa kwama-grinder kagesi ngaphezu kwalawo aqhutshwa umoya. Izigayi zikagesi zinikeza ukulawula okukhulu nokunemba, futhi ngokuvamile zithulile futhi zihlangene kakhulu kunamamodeli ashayelwa umoya. Futhi zidinga ukunakekelwa okuncane futhi zingasetshenziswa kuzilungiselelo ezibanzi, kusukela elabhorethri yamazinyo ukuya emtholampilo wamazinyo ohambahambayo.
Isidingo sekhwalithi ephezulu yokwenziwa kwamazinyo siphinde saqhuba ukuthuthukiswa kwezinto ezintsha nezindlela zokugaya. Isibonelo, i-zirconia ne-lithium disilicate yizinto ezimbili ezithandwayo ezisetshenziswa ekubuyiselweni kwamazinyo zanamuhla ezidinga amasu akhethekile okugaya ukuze kuzuzwe umumo nokuthungwa okufunayo. Amasu okugaya anjengokugaya idayimane, ukugaya nge-ultrasonic kanye nokugaya ngesivinini esikhulu konke kubonakale ukusetshenziswa okwandisiwe eminyakeni yamuva.
Njengoba ubuchwepheshe bamazinyo buqhubeka nokuthuthuka, ukuthuthukiswa kwezinto ezintsha namasu kungenzeka kuqhubeke, okuqhubekisela phambili izinguquko emakethe yokugaya amazinyo. Isidingo esikhulayo sokunemba, ukusebenza kahle, kanye nokunethezeka kwesiguli kulindeleke ukuthi siphushe abakhiqizi ukuthi bakhe amathuluzi amasha naqanjiwe ahlangabezana nezidingo eziguqukayo zomkhakha wamazinyo.
