Naphezu kobude besikhathi kusukela kwasungulwa umkhakha wamazinyo wedijithali ngo-1985, kusekhona impikiswano eqhubekayo, enempilo mayelana nenani layo nendawo ezinkambisweni zamazinyo ezijwayelekile.

Lapho kuhlolwa ubuchwepheshe obusha, ochwepheshe batusa ukucabangela imibuzo emithathu:

·  Ingabe ithuthukisa kalula ukunakekelwa?

·  Ingabe kwenza isiguli sikhululeke kakhudlwana?

·  Ingabe ithuthukisa ikhwalithi?

Uma ucabanga ukutshala imali kusihlalo we-CAD/CAM, sethemba ukuthi uzothola lokhu kubuka konke kwezinzuzo zayo kanye nezithiyo, ezikhuluma namaphuzu angenhla, ziwusizo.  

WHAT PROPONENTS LOVE

Ukonga Isikhathi  Inzuzo eyinhloko neyaziwa kakhulu ye-chairside CAD/CAM ukuthi yonga kokubili isikhathi sikadokotela nesiguli ngokuletha ukubuyisela kokugcina ngosuku olulodwa. Akukho ukuqokwa kwesibili, akukho okwesikhashana okumele kwenziwe noma ukuphinda kumiswe usimende. Eqinisweni, ubuchwepheshe buvumela odokotela ukuthi basebenze futhi balethe ukubuyisela izinyo elilodwa elilodwa ngokuvakasha okukodwa.

Ngaphezu kwalokho, ngokuqeqesha abasizi ukuskena ama-arches kanye nokuluma, nokusingatha eminye imisebenzi, udokotela angatholakala ukuze abone ezinye iziguli futhi enze ezinye izinqubo, ngaleyo ndlela andise isikhathi sakhe.

Ukufaka amabala kuwubuciko. Abanye odokotela basebenzisa ilebhu ukuze babuyisele izinto zangaphambili ekuqaleni baze bakhe izinga labo lokunethezeka. Kodwa uma sebejwayele ukwenza amabala, bathola ukuthi ukuba neyunithi ehhovisi kubanika ikhono lokushintsha umthunzi wokubuyisela ngaphandle kokuthi bathumele umkhiqizo elebhu, konga kokubili isikhathi nezindleko.

Akukho Okuvelayo Okubonakalayo  Ubuchwepheshe be-CAD/CAM abudingi okuvelayo ngokomzimba, okudala izinzuzo ezimbalwa. Kokunye, isusa ubungozi bokuncipha kombono, okuholela ekulungisweni okumbalwa kanye nesikhathi esingaphansi kwesitulo.

Ngaphezu kwalokho, iqeda isidingo sokuphinda okuvelayo. Uma kunesikhala esithombeni, ungakwazi ukuskena kabusha indawo ekhethiwe noma izinyo lonke kuye ngokuthi yini edingekayo.

Ukudala okuvelayo kwedijithali kuphela kukuvumela ukuthi ulondoloze okuvela ezigulini isikhathi eside njengoba ufisa ngaphandle kwesidingo sendawo ebonakalayo yokugcina ukusakaza. Okuvelayo kwedijithali futhi kuqeda isidingo sokuthenga amathreyi avelayo nezinto zokwakha, kanye nezindleko zokuthumela okuvelayo elebhu. Inzuzo ehlobene: ukuncishiswa kokunyathela kwemvelo.

Induduzo Yesiguli Engcono  Iziguli eziningi azikhululekile ngenqubo yokucabanga, engabangela ukungakhululeki, ukuvala umlomo nokucindezeleka. Ukususa lesi sinyathelo kungasho izilinganiso zehhovisi nezidokotela eziphezulu ku-inthanethi. Ngokuhamba kweminyaka, isithwebuli se-intraoral siye saba sincane futhi siyashesha, okuqeda isidingo sokuba iziguli zigcine imilomo yazo ivulekile isikhathi eside—into eyayiyinkinga ekuqaleni.

Ezigulini ezinokukhubazeka kwengqondo noma izinselele zomzimba, odokotela bamazinyo abaningi bakuthola kuwusizo kakhulu ukuba nekhono lokuletha i-prosthesis ngosuku olufanayo.

Ngokuphathelene nokwamukela ukwelashwa, izikena zivumela odokotela ukuba babonise iziguli umkhiqizo wokugcina, othuthukisa ukwaneliseka.

Ukusetshenziswa Okuningi  I-Chairside CAD/CAM yenza odokotela bakwazi ukwenza imiqhele, amabhuloho, ama-veneers, ama-inlay nama-onlay, futhi bafake iziqondiso zokuhlinza. Ezinye izikena, ezifana ne-iTero, zinikeza ikhono lokwenza onogada basebusuku nokucacisa ama-aligner endlini. Okunye, okuvelayo kwedijithali kungathunyelwa elebhu yaleyo mikhiqizo.

Isici esijabulisayo  Odokotela abaningi abenza amazinyo edijithali bayayijabulela ngempela le nqubo. Bathola ukuthi ukufunda ukusebenzisa lobu buchwepheshe kanye nokubuhlanganisa emisebenzini yabo kukhulisa ukwaneliseka kwabo ngokomsebenzi.

Ikhwalithi Ethuthukisiwe  Labo abasebenzisa uhlelo lwe-CAD/CAM nabo baphikisa ngokuthi luthuthukisa ukunakekelwa. Ngenxa yokuthi ikhamera ikhulisa izinyo eselilungisiwe, odokotela bamazinyo bangakwazi ukulungisa futhi bathuthukise ifomu namamajini ngokushesha.

Inzuzo Yokuncintisana  Kweminye imiphakathi, ukuhlinzeka ngezinsizakalo zamazinyo edijithali kungase kukunikeze inzuzo yamasu. Lapho unquma ukuthi uzotshala yini kulobu buchwepheshe, cabanga ngalokho okwenziwa izimbangi zakho nokuthi ngabe iziguli bezikubuza mayelana “nodokotela wamazinyo wosuku olufanayo” noma “amazinyo ngosuku.”

WHAT CRITICS POINT OUT

Isixazululo Esibiza Kakhulu  Udokotela wamazinyo we-Chairside digital uwukutshalwa kwezimali okubalulekile okubandakanya izingxenye eziningi zobuchwepheshe, okuhlanganisa nesistimu ye-CAD/CAM ngokwayo, i-Cone Beam CT ye-3-D imaging, kanye nesikena sokubonwayo sokuvela kwedijithali nokuhlaziywa kombala okunembile ukuze kungcoliswe amabala. Kukhona nezindleko zokuvuselelwa kwesoftware, kanye nezinto zokubuyisela esimweni.

Nakuba abasebenza ngabodwana bengakwazi ukuphumelela ekwenzeni utshalomali lwabo luzikhokhele ngemva kweminyaka embalwa, kungase kube lula ukucwila phakathi uma usenza iqembu.

Khumbula ukuthi imikhuba ayisadingi ukuthatha indlela yokusho konke noma lutho kudokotela wamazinyo wedijithali. Nakuba i-CAD/CAM yake yadinga ukuthengwa kwesistimu ephelele, izikena ze-intraoral zanamuhla zigcina izithombe ngamafayela e-stereolithography angafundwa ilebhu. Lokhu kwenza kube nokwenzeka ukuqalisa ngezithombe zedijithali futhi wengeze izinto zokugaya zasendlini kamuva, uma abasebenzi bakho sebenethezeke kakhulu ngobuchwepheshe.

Lapho unquma ukuthi uzotshala yini kudokotela wamazinyo wedijithali, cabangela ukonga kanye nezindleko. Isibonelo, ukwenza ama-prostheses endlini kusho ukonga ezinkokhelweni zaselabhu, futhi ukusebenza kahle okuthuthukisiwe kuzosiza ukukhokha izindleko zokutshalwa kwezimali kwakho.

Ijika Lokufunda  Odokotela nabasebenzi bazodinga ukuthola ukuqeqeshwa mayelana nendlela yokusebenzisa isofthiwe esebenzisa ubuchwepheshe be-CAD/CAM. Isofthiwe entsha yenza inombolo yezinyathelo ngemuva, ivumela udokotela wamazinyo ukuthi afike ekubuyiselweni ngokuchofoza okumbalwa kwegundane. Ukwamukela udokotela wamazinyo wedijithali kusho ukulungisa indlela entsha yokusebenza.

Izinkathazo Zekhwalithi  Ngenkathi ikhwalithi yokubuyiselwa kwe-CAD/CAM yangaphambili ibe yinto ekhathazayo, njengoba umkhakha wamazinyo wedijithali uthuthuka, kanjalo nekhwalithi yokubuyisela. Isibonelo, ukubuyisela okusebenzisa isibambo seyunithi ye-5-axial milling kangcono futhi kunembe kakhulu kunalezo ezigaywe ngeyunithi engu-4-axial.

Ucwaningo luphakamisa ukuthi ukubuyiselwa kwe-CAD/CAM kwanamuhla kunamandla futhi mancane amathuba okuthi kuphuke kunalezo ezigaywe ngezinto zangaphambili, nokuthi zilingana kangcono futhi.

Izinto eziningi zidlala esinqumweni sokutshala imali kubuchwepheshe be-CAD/CAM. Impumelelo incike ezintweni eziningana eziguquguqukayo, okuhlanganisa umdlandla wakho siqu, ukuzimisela kwabasebenzi bakho ukufunda ubuchwepheshe obusha nokushintsha izinqubo ezihlala isikhathi eside, kanye nemvelo yokuncintisana yokwenza kwakho.
