Inzuzo ye-CAM CAD

Udokotela wamazinyo we-CAD/CAM wenza ngokushesha inqubo eyaziwa ngokuthi idla isikhathi futhi cishe yenziwa ngesandla. Isebenzisa umklamo wakamuva nezindlela zokukhiqiza, i-CAD/CAM isiqale inkathi entsha kwezokwelashwa kwamazinyo esibonakala ngezinqubo ezisheshayo, ukuhamba komsebenzi okusebenza kahle kakhulu kanye nolwazi olungcono lwesiguli sisonke. Kule bhulogi, sizongena ngokujulile kudokotela wamazinyo we-CAD/CAM, okuhlanganisa ukuthi usebenza kanjani, ukuthi uhilelani, ubuhle nobubi bayo, kanye nobuchwepheshe obuhilelekile.

Okokuqala, ake sichaze amagama athile.

I-Computer-aid design (CAD) ibhekisela ekwenzeni imodeli ye-3D yedijithali yomkhiqizo wamazinyo ngesofthiwe, ngokuphambene ne-wax-up evamile.

Ukukhiqiza okusizwa ngekhompyutha (i-CAM) kubhekisela kumasu afana nokugaya kwe-CNC nokuphrinta kwe-3D okwenziwa ngemishini futhi alawulwa yisofthiwe, ngokuphambene nezinqubo zendabuko ezifana nokusakaza noma ukubeka izendlalelo ze-ceramic, ezisebenza ngesandla ngokuphelele.

Udokotela wamazinyo we-CAD/CAM uchaza ukusetshenziswa kwamathuluzi e-CAD nezindlela ze-CAM ukuze kukhiqizwe imiqhele, amazinyo okufakelwa, ama-inlay, ama-onlay, amabhuloho, ama-veneers, izimila, kanye nokubuyiselwa kwe-abutment noma izitho zokufakelwa.

Ngamagama alula, udokotela wamazinyo noma uchwepheshe uzosebenzisa isofthiwe ye-CAD ukuze enze umqhele obonakalayo, isibonelo, ozokhiqizwa ngenqubo ye-CAM. Njengoba ungacabanga, ukunakekelwa kwamazinyo kwe-CAD/CAM kuphindaphindeka futhi kuyahlaziywa kunezindlela ezijwayelekile.

Ukuvela kwe-CAD/CAM yamazinyo

Ukwethulwa kodokotela bamazinyo be-CAD/CAM kuguqule indlela izinqubo zamazinyo namalebhu amazinyo akusingatha ngayo okuvelayo, ukuklama, nokukhiqiza.  

Ngaphambi kobuchwepheshe be-CAD/CAM, odokotela bamazinyo babethatha umbono wamazinyo esiguli besebenzisa i-alginate noma i-silicone. Lo mbono uzosetshenziselwa ukwenza imodeli ngokhonkolo, kungaba ngudokotela wamazinyo noma uchwepheshe elebhu yamazinyo. Imodeli ye-plaster izobe isisetshenziselwe ukwenza ama-prosthetics womuntu siqu. Kusukela ekugcineni kuye ekupheleni, le nqubo yayidinga ukuthi isiguli sihlele izikhathi ezimbili noma ezintathu, kuye ngokuthi umkhiqizo wokugcina ubunembe kangakanani.

Udokotela wamazinyo we-CAD/CAM kanye nobuchwepheshe bayo obuhlobene kwenze inqubo yangaphambilini eyenziwa ngesandla yaba idijithali kakhulu.  

Isinyathelo sokuqala senqubo singenziwa ngokuqondile ehhovisi likadokotela wamazinyo lapho udokotela wamazinyo erekhoda umbono wedijithali wamazinyo esiguli ngesithwebuli se-3D se-intraoral. Iskena se-3D esiwumphumela singathunyelwa elebhu yamazinyo, lapho ochwepheshe beyivula ngesofthiwe ye-CAD futhi bayisebenzisele ukuklama imodeli ye-3D yengxenye yamazinyo ezophrintwa noma igaywe.

Ngisho noma udokotela wamazinyo esebenzisa okubonakalayo ngokomzimba, amalebhu amazinyo angakwazi ukusebenzisa ubuchwepheshe be-CAD ngokufaka isithombe esibonakalayo ngedijithali ngesithwebuli sedeskithophu, asenze sitholakale ngaphakathi kwesofthiwe ye-CAD.  

Izinzuzo CAD/CAM wamazinyo

Inzuzo enkulu ye-CAD/CAM yamazinyo ijubane. Lezi zinqubo zingaletha umkhiqizo wamazinyo esikhathini esincane nje sosuku olulodwa—futhi ngezinye izikhathi ngosuku olufanayo uma udokotela wamazinyo eklama futhi ekhiqiza endlini. Odokotela bamazinyo bangakwazi futhi ukuthatha okuvelayo okudijithali okuningi ngosuku kunokuvela ngokomzimba. I-CAD/CAM iphinde ivumele amalebhu amazinyo ukuthi aqedele imikhiqizo eminingi kakhulu ngosuku ngomzamo omncane kanye nezinyathelo ezimbalwa ezenziwa ngesandla.

Ngenxa yokuthi udokotela wamazinyo we-CAD/CAM uyashesha futhi unokuhamba komsebenzi okulula, futhi kubiza kakhulu izinqubo zamazinyo namalebhu. Isibonelo, asikho isidingo sokuthenga noma ukuthumela izinto ezibonakalayo noma ukusakaza. Ngaphezu kwalokho, amalebhu amazinyo angakwazi ukwenza ama-prosthetics amaningi ngosuku kanye nochwepheshe ngamunye ngalabu buchwepheshe, obungasiza amalebhu ukubhekana nokushoda kochwepheshe abakhona.

Udokotela wamazinyo we-CAD/CAM ngokuvamile udinga ukuvakashelwa kwesiguli okumbalwa, futhi—okukodwa okokuskena kwangaphakathi komlomo kanye nokukodwa kokubekwa—okulula kakhulu. Futhi ikhululekile kakhulu ezigulini ngoba zingaskenwa ngedijithali futhi zigweme inqubo engathandeki yokubamba i-viscous wad ye-alginate emlonyeni wazo kuze kube yimizuzu emihlanu ngenkathi ihlezi.

Ikhwalithi yomkhiqizo nayo iphakeme nge-CAD/CAM yamazinyo. Ukunemba kwedijithali kwezikena ze-intraoral, isofthiwe yokuklama ye-3D, imishini yokugaya kanye namaphrinta e-3D ngokuvamile kukhiqiza imiphumela ebikezelwe kakhulu evumela iziguli ngokunembe kakhudlwana. Udokotela wamazinyo we-CAD/CAM uphinde wenza kwaba nokwenzeka ngezinqubo zokuphatha ukubuyisela okuyinkimbinkimbi kalula.

Izinhlelo zokusebenza ze-CAD/CAM zamazinyo

Izinhlelo zokusebenza zamazinyo e-CAD/CAM zisemsebenzini wokubuyisela esimweni, noma ukulungiswa nokushintshwa kwamazinyo abolile, awonakele, noma angekho. Ubuchwepheshe be-CAD/CAM bungasetshenziswa ukwakha izinhlobonhlobo zemikhiqizo yamazinyo, kuhlanganise:

Imiqhele

Ama-inlays

 Ama-onlays

Ama-Veneers

Amabhuloho

Amazinyo okufakelwa agcwele nayingxenye

Ukubuyisela kabusha

Sekukonke, udokotela wamazinyo we-CAD/CAM uyathandeka ngoba uyashesha futhi kulula kuyilapho uvame ukuletha imiphumela engcono.

Isebenza kanjani udokotela wamazinyo we-CAD/CAM?

Udokotela wamazinyo we-CAD/CAM ulandela inqubo eqondile, futhi ezimeni lapho zonke izinqubo zenziwa endlini, zingaqedwa emizuzwini engama-45. Izinyathelo ngokuvamile zihlanganisa:

Ukulungiselela: Udokotela wamazinyo ususa noma yikuphi ukubola ukuze aqinisekise ukuthi amazinyo esiguli alungele ukuskenwa nokubuyiselwa.

Ukuskena: Esebenzisa isithwebuli esiphathwa ngesandla se-intraoral, udokotela wamazinyo uthwebula izithombe ze-3D zamazinyo nomlomo wesiguli.

Idizayini: Udokotela wamazinyo (noma elinye ilungu lomkhuba) ungenisa izikena ze-3D kusofthiwe ye-CAD futhi udale imodeli ye-3D yomkhiqizo wokubuyisela.

Ukukhiqiza: Ukubuyisela ngokwezifiso (umqhele, i-veneer, amazinyo okufakelwa, njll.) kuphrintiwe nge-3D noma kugaywe.

Ukuqeda: Lesi sinyathelo sincike ohlotsheni lomkhiqizo nezinto ezibonakalayo, kodwa singafaka ukucwilisa, ukungcolisa, ukucwebezela, ukupholisha kanye nokudubula (kwe-ceramic) ukuze kuqinisekiswe ukulingana nokubukeka okunembile.

Ukubekwa: Udokotela wamazinyo ufaka ama-prosthetics okubuyisela emlonyeni wesiguli.

Okuvelayo kwedijithali nokuskena

Enye yezinzuzo ezinkulu kakhulu zobudokotela bamazinyo be-CAD/CAM ukuthi isebenzisa okuvelayo kwedijithali, okulula kakhulu ezigulini futhi kusiza odokotela bamazinyo ukuthi bathole umbono we-360-degree wombono. Ngale ndlela, okuvelayo kwedijithali kwenza kube lula kodokotela bamazinyo ukuqinisekisa ukuthi ukulungiswa kwenziwa kahle ukuze ilebhu ikwazi ukwenza ukubuyisela okungcono kakhulu ngaphandle kwesidingo sokuqokwa kwesinye isiguli ukuze senze izinguquko ezengeziwe.

Okuvelayo kwedijithali kwenziwa ngezikena ze-3D ze-intraoral, okungamathuluzi amancane aphathwa ngesandla afakwa ngqo emlonyeni wesiguli ukuze kuskenwe amazinyo ngemizuzwana. Amanye alawa madivayisi afana ne-wand afaka namathiphu amancane okwamukela iziguli ezingakwazi ukuvula imilomo yazo kakhulu.

Lezi zithwebuli zingasebenzisa ividiyo noma ukukhanya kwe-LED ukuze zithwebule ngokushesha izithombe ezinokulungiswa okuphezulu, ezinemibala egcwele zamazinyo nomlomo wesiguli. Izithombe eziskeniwe zingathunyelwa ngqo kusofthiwe ye-CAD ukuze idizayinwe ngaphandle kwezinyathelo eziphakathi. Izithombe zedijithali zinembe kakhulu, zinemininingwane eminingi, futhi zijwayele ukuvela emaphutheni kunemibono evamile ye-analog (ebonakalayo).

Enye inzuzo ebalulekile yale ndlela ukuthi udokotela wamazinyo angaqinisekisa ukuthi kunesikhala esanele somphikisi futhi ahlole ikhwalithi yokuvala. Ngaphezu kwalokho, ilebhu yamazinyo ingathola umbono wedijithali emizuzwini embalwa ngemva kokuba isilungisiwe futhi ibuyekezwa udokotela wamazinyo ngaphandle kwesikhathi noma izindleko ngokuvamile ezihlotshaniswa nokuthunyelwa okubonakalayo ngokomzimba. 


Ukugeleza komsebenzi we-CAD kodokotela bamazinyo

Ngemuva kokuthi ukuskena kwe-3D kulethwe kuhlelo lokusebenza lwesofthiwe ye-CAD, udokotela wamazinyo noma uchwepheshe wedizayini angasebenzisa isofthiwe ukuze enze umqhele, i-veneer, amazinyo okufakelwa, noma okufakelwayo.

Lezi zinhlelo zokusebenza zesofthiwe zivame ukuqondisa umsebenzisi ngenqubo yokudala umkhiqizo ofana nokuma, usayizi, i-contour nombala wezinyo lesiguli. Isofthiwe ingase ivumele umsebenzisi ukuthi alungise ukujiya, i-engeli, isikhala sikasimende nezinye izinto eziguquguqukayo ukuze kuqinisekiswe ukulingana okufanele nokuvala.

Isofthiwe ye-CAD ingase futhi ihlanganise amathuluzi akhethekile, njengesihlaziyi sothintana naye, isihloli se-occlusion, i-virtual articulator, noma ilabhulali ye-anatomy, konke okusiza ukuthuthukisa idizayini. Indlela ye-eksisi yokufaka ingase futhi inqunywe. Izinhlelo zokusebenza eziningi ze-CAD zisebenzisa futhi ubuhlakani bokwenziwa (AI) ukwenza lula, ukuqondisa kanye nokwenza eziningi zalezi zinyathelo ngokuzenzakalelayo noma ukunikeza iziphakamiso ukuze umsebenzisi azilandele.

Isofthiwe ye-CAD ingasiza futhi ekukhetheni izinto ezibonakalayo ngoba impahla ngayinye inikeza inhlanganisela ehlukile yamandla aguquguqukayo, amandla emishini kanye nokuguquguquka.
