Abantu baseMelika abangaphezu kwezigidi ezingu-36 abanamazinyo, futhi abantu abayizigidi ezingu-120 e-US balahlekelwa okungenani izinyo elilodwa.Njengoba lezi zinombolo kulindeleke ukuthi zikhule emashumini amabili eminyaka ezayo, imakethe yamazinyo okufakelwa e-3D kulindeleke ukuthi ikhule kakhulu.

USam Wainwright, Umphathi Womkhiqizo Wamazinyo kwa-Formlabs, uphakamise ngesikhathi sewebhu yewebhu yakamuva yenkampani ukuthi “ngeke amangale ukubona u-40% wamazinyo okufakelwa eMelika enziwa ngokuphrinta kwe-3D,” ethi kunengqondo “ezingeni lobuchwepheshe ngoba kukhona. akukho ukulahleka kwezinto.”Uchwepheshe wacubungula amanye amasu afakazele ukuthi asebenzela amazinyo okufakelwa e-3D aphrintiwe ngobuhle.I-webinar, enesihloko esithi Can 3D amazinyo okufakelwa aphrintiwe abukeke emuhle?, inikeze odokotela bamazinyo, ochwepheshe, nanoma ubani onentshisekelo yokusebenzisa ukuphrinta kwe-3D ukuthuthukisa amazinyo okufakelwa, amathiphu okuthi ungazinqamula kanjani izindleko zempahla ngokufika ku-80% (uma kuqhathaniswa namakhadi okufakelwa endabuko kanye ne-acrylic);yenza izinyathelo ezimbalwa ukuze uthole imiphumela yekhwalithi ephezulu, futhi uvikele amazinyo ekubukekeni okungezona ezemvelo.

“Lena yimakethe ekhula njalo enezinketho eziningi.Amazinyo okufakelwa e-3D aphrintiwe ayinto entsha kakhulu, ikakhulukazi kuma-prosthetics akhiphekayo (into engakaze yenziwe idijithali) ngakho-ke kuzothatha isikhathi ukuthi amalebhu, odokotela bamazinyo neziguli zijwayele.Impahla ikhonjiswe ukusetshenziswa isikhathi eside kodwa ukwamukelwa okushesha kakhulu kwalobu buchwepheshe kuzoba ukuguqulwa ngokushesha kanye namazinyo okufakelwa esikhashana, anengozi ephansi evumela ochwepheshe bamazinyo ukuthi bahambe bengagijimi kulobu buchwepheshe obusha.Silindele nokuthi ama-resin abe ngcono, aqine futhi abe nobuhle ngokuhamba kwesikhathi,” kusho uWainwright.

Eqinisweni, onyakeni odlule, i-Formlabs isivele ikwazile ukuthuthukisa ama-resin ayithengisayo ukuze ochwepheshe bezokwelapha benze izitho zokwenziwa ngomlomo, ezibizwa ngokuthi i-Digital Dentures.Lawa ma-resin amasha agunyazwe yi-FDA awafani nje namazinyo okufakelwa endabuko kodwa futhi ashibhile kunezinye izinketho.Ngo-$299 we-resin base base kanye no-$399 we-resin yamazinyo, inkampani ilinganisela ukuthi inani eliphelele lezindleko ze-maxillary resin ngu-$7.20.Ngaphezu kwalokho, ama-Formlabs nawo asanda kukhipha iphrinta entsha ye-Form 3, esebenzisa izisekelo zokuthinta okulula: okusho ukuthi ukucubungula ngemva kokuba sekulula.Ukususwa kosekelo kuzoshesha kuFomu 3 kuneFomu 2, okusho ukuthi izindleko zempahla nesikhathi esincane.

“Sizama ukuvimbela amazinyo ukuthi angabukeki ngendlela engeyona eyemvelo, futhi ngezinye izikhathi ngalawa mazinyo okufakelwa e-3D, ubuhle busuke buhlushwa yiwo ngempela.Sithanda ukucabanga ukuthi amazinyo okufakelwa kufanele abe ne-gingiva efana nempilo, amaphethelo emvelo omlomo wesibeletho, amazinyo abuka ngamanye, futhi kube lula ukuhlangana,” kusho u-Wainright.

Ukugeleza okujwayelekile okuyisisekelo okuhlongozwe u-Wainright ukulandela ukugeleza komsebenzi okuvamile kuze kube yilapho amamodeli okugcina ethelwa futhi achazwa nge-wax rim, lokho kusetha kudinga ukwenziwa kwedijithali ngesithwebuli samazinyo se-3D sedeskithophu esivumela idizayini yedijithali kunoma iyiphi i-CAD yamazinyo evulekile. uhlelo, olulandelwa ukuphrinta kwe-3D isisekelo namazinyo, futhi ekugcineni emva kokucubungula, ukuhlanganisa nokuqeda ucezu.

“Ngemva kokwenza izingxenye eziningi kangaka, ukuphrinta ithoni yamazinyo okufakelwa nezisekelo, nokuzihlanganisa, siqhamuke nezindlela ezintathu zokwakheka kobuhle obuphrintiwe be-3D.Esikufunayo ukugwema eminye yemiphumela yamazinyo okufakelwa edijithali anamuhla, njengemikhiqizo enesisekelo esifiphele noma i-gingiva, okuwukungcola kancane ngokombono wami.Noma ufika mayelana nesisekelo esishintshashintshayo esishiya izimpande zisobala, futhi okokugcina uma usebenzisa ukuhamba komsebenzi kwamazinyo ahlukene ungagcina usuxhumeke kakhulu phakathi kwe-interproximal.Futhi njengoba i-papillae iyizingxenye ezinyathelisiwe ezacile ngempela, kulula ngempela ukubona amazinyo ehlangana, ebukeka engezona ezemvelo.”

U-Wainright uphakamisa ukuthi ngenqubo yakhe yokuqala yamazinyo yobuhle, abasebenzisi bangakwazi ukulawula ukujula kokungena kwezinyo kanye ne-engeli elingena ngayo noma eliphumayo, ngokusebenzisa umsebenzi omusha kusofthiwe ye-CAD ye-3Shape Dental System (inguqulo 2018+).Inketho ibizwa nge-coupling mechanism, futhi inika umsebenzisi amandla okulawula okwengeziwe kunangaphambili, into eza kahle kakhulu uma kucatshangelwa ukuthi "ubude be-subgingival izinyo linobude obuningi, isibopho siba namandla nesisekelo."

“Isizathu esenza amazinyo okufakelwa e-3D ahluke kunamazinyo enziwe ngokwesiko ukuthi ama-resin esisekelo namazinyo afana nabazala.Lapho izingxenye ziphuma kuphrinta futhi uzigeza, zicishe zithambe futhi zinamathele, ngoba zelaphekile kancane, phakathi kwamaphesenti angama-25 no-35.Kodwa phakathi nenqubo yokugcina yokwelapha nge-UV, izinyo nesisekelo kuba ingxenye eyodwa eqinile.”

Eqinisweni, uchwepheshe wamazinyo okufakelwa ubonisa ukuthi abasebenzisi kufanele belaphe isisekelo esihlanganisiwe namazinyo ngesibani esiphathwayo se-UV sokwelapha, esiya ngaphakathi, ukuze nje babambe izingxenye ndawonye.Uma umsebenzisi esehlole ukuthi zonke izimbobo zigcwalisiwe futhi asuse noma iyiphi insalela eyisisekelo, amazinyo okufakelwa asuke eseqedile futhi alungele ukucwiliswa emanzini imizuzu engu-30 ku-glycerine engu-80 degrees celsius, ihora lonke lesikhathi sokwelashwa.Ngaleso sikhathi, ucezu lungaqedelwa nge-UV glaze noma isondo lokupholisha okucwebezelayo.

Isu lesibili elinconyiwe lamazinyo okufakelwa obuhle libandakanya ukuhlanganisa kalula kwe-arch ngaphandle kwe-bulky interproximal.

U-Wainright wachaza ukuthi usungula "lawa macala afakwe ku-CAD ngakho-ke ahlukaniswe nge-100% ndawonye ngoba kulula kakhulu ukuba nokubekwa kwamazinyo okungaguquki, esikhundleni sokukwenza ngamunye ngamunye okungase kube nzima kakhulu.Ngiqala ukuthekelisa i-arch ehlukanisiwe, kodwa umbuzo lapha ukuthi ungakwenza kanjani ukuxhumana phakathi kwamazinyo kubukeke kungokwemvelo, ikakhulukazi uma une-papilla encane kakhulu.Ngakho-ke ngaphambi kokuhlanganisa, phakathi nengxenye yethu yokusekela yokususwa kwenqubo, sizothatha idiski yokusika futhi sinciphise ukuxhuma okuphakathi nendawo ukusuka enqenqemeni yomlomo wesibeletho kuye phezulu kuya ku-incisal.Lokhu kusiza ngempela ubuhle bamazinyo okufakelwa ngaphandle kokukhathazeka nganoma yiziphi izikhala.”

Futhi uncoma ukuthi phakathi nenqubo yokuhlanganisa, abasebenzisi bangaxubha kalula ku-gingiva resin ezindaweni ukuze baqiniseke ukuthi akukho moya, izikhala noma i-voids, ukugcina amandla.

“Gcina iso lakho libheke amabhamuza,” uphindaphinda u-Wainright izikhathi eziningi, echaza ukuthi “uma usebenzisana kancane ukuze uthole inhlaka ezikhaleni, iwanciphisa ngempela amabhamuza.”

Ubuye wengeza ngokuthi isihluthulelo “ukugeleza kunhlaka eningi ekuqaleni, esikhundleni sokuvele uyimanzise, ​​futhi lapho isiminyanisiwe izogelezela kuleyo ndawo.Ekugcineni, ukuchichima kungasulwa ngomunwe onamagilavu.”

“Kubukeka kulula kodwa lezi yizinto esizifunda ngokuhamba kwesikhathi.Ngiphindaphinde eziningi zalezi zinqubo izikhathi ezimbalwa futhi ngaba ngcono, namuhla kungase kungithathe imizuzu eyi-10 uma ngiqeda ukuqeda amazinyo okufakelwa owodwa.Ngaphezu kwalokho, uma ucabanga ngezisekelo zokuthinta okuthambile kuFomu 3, ukucutshungulwa kokuthunyelwe kuzoba lula nakakhulu, njengoba noma ubani ezokwazi ukuklebhula futhi engeze ukuqeda okuncane kakhulu emkhiqizweni. "

Ngendlela yokugcina yobuhle, u-Wainwright uphakamise ukulandela isibonelo "samazinyo okufakelwa ase-Brazilian", esinikeza indlela ekhuthazayo yokudala i-gingiva efana nempilo.Uthi uphawule ukuthi abantu baseBrazil sebengochwepheshe ekwakhiweni kwamazinyo okufakelwa, bengeza ama-resin akhanyayo esisekelweni esivumela umbala we-gingiva wesiguli ukuba ubonakale.Uphakamise ukuthi i-LP resin Formlabs resin nayo iyashintshashintsha, kodwa uma ihlolwa kumodeli noma emlonyeni wesiguli, “yengeza ukujula okuhle ku-gingiva ngokwayo inikeze ukukhanya okuwusizo kobuhle.”

“Lapho amazinyo okufakelwa ehlezi ngaphakathi emlonyeni, i-gingiva yemvelo yesiguli ibonakala ngokwenza amazinyo okufakelwa aphile.”

Amafomu aziwa ngokudala amasistimu okuphrinta e-3D athembekile, afinyelelekayo ochwepheshe.Ngokusho kwenkampani, kule minyaka eyishumi edlule, imakethe yamazinyo isiyingxenye enkulu yebhizinisi lenkampani nokuthi amaForlabs athenjwa ngabaholi bemboni yamazinyo emhlabeni wonke, "ehlinzeka ngosekelo nabasebenzi abangaphezu kuka-75 kanye nonjiniyela abangaphezu kuka-150."

Ithumele amaphrinta angaphezu kuka-50,000 emhlabeni jikelele, ngamashumi ezinkulungwane zochwepheshe bamazinyo abasebenzisa iFomu 2 ukwenza ngcono izimpilo zamakhulu ezinkulungwane zeziguli.Ukwengeza, ukusebenzisa izinto zabo kanye namaphrinta ekuhlinzeni okungaphezu kuka-175,000, ama-splints angu-35,000 kanye nezingxenye zamazinyo eziphrintiwe ze-3D ezingu-1,750,000.Enye yezinhloso kwaFormlabs ukukhulisa ukufinyelela kokwenziwa kwedijithali, ukuze noma ubani enze noma yini, lesi esinye sezizathu ezenza inkampani yenze ama-webinars, ukusiza wonke umuntu afike lapho.

U-Wainright uphinde waveza ukuthi i-Formlabs izokhipha amazinyo okufakelwa amabili amasha, i-RP (ebomvana ebomvana) ne-DP (epinki emnyama), kanye nezimo ezimbili ezintsha zamazinyo okufakelwa, i-A3 ne-B2, ezohambisana ne-A1, A2, A3 esivele ikhona. 5, kanye B1.

Uma ungumlandeli omkhulu wama-webinars, qiniseka ukuthi uhlola okwengeziwe kumawebinars e-3DPrint.com ngaphansi kwesigaba Sokuqeqesha.
