I-Elastics Enemibala Ithuthukisa Kanjani Ukuhambisana Nemithetho Ezigulini Ezisencane Ezisebenzisa I-Orthodontic?

Isingeniso

Ukwelashwa kwamazinyo kwentsha kuncike kakhulu ekuziphatheni nasekulungiseni, futhi ukuguguleka kwansuku zonke kuvame ukuba lapho izinhlelo ziwohloka khona. Esinye isikhuthazo esiphumelelayo ngokumangalisayo umbala: ukunika intsha ukukhetha ama-elastic anemibala kungenza ukwelashwa kuzizwe kuyimfihlo, kubonakale, futhi kulula ukuzibophezela kukho. Lesi sihloko sichaza ukuthi lokho kukhetha okuncane okusekela kanjani ukuthobela imithetho, ukuthi kungani kuhambisana nesayensi yezengqondo yentsha, nokuthi kungasho ukuthini ekusebenzeni kahle kokwelashwa, imiphumela yokuqokwa, kanye nokwaneliseka kwesiguli. Siphinde simise izici ezisebenzayo odokotela nabazali okufanele bazicabangele lapho besebenzisa ama-elastic anemibala ukukhuthaza ukubambisana okuqhubekayo.

Indlela Ama-Elastics Anemibala Angayithuthukisa Ngayo Ukuhambisana Ne-Teen Orthodontic

Ukuhambisana nemithetho yentsha kusalokhu kungenye yezindlela ezingalindelekile kakhulu ekwelashweni kwamazinyo. Nakuba ukuthuthukiswa kwe-biomechanical kuye kwathuthukisa ukwakheka kwama-bracket kanyeama-alloy e-archwire, imiphumela yezokwelapha isancike kakhulu ekubambisaneni kweziguli, ikakhulukazi maqondana nokuhlanzeka komlomo kanyeukuguguleka okuqhubekayo kwama-interarch elastikiAmanani okungalandeli imithetho ezigulini ezisencane ezisebenzisa amazinyo amazinyo avame ukusuka ku-30% kuya ku-50%, okuyiphutha lokuziphatha elingandisa kakhulu isikhathi sokwelashwa futhi liphazamise imiphumela yokugcina yokuvaleka kwamazinyo.

Ukuze kuncishiswe lokhu, odokotela basebenzisa kakhulu izindlela zokuziphatha ukuze bakhuthaze ubunikazi besiguli enkambisweni yokwelashwa. Ukuhlanganiswa kwama-ligatures elastomeric anemibala kanye nama-interarch elastiki kusebenza njengethuluzi lezengqondo elingabizi kakhulu nelinomthelela omkhulu. Ngokuguqula inqubo yezokwelapha engenzi lutho ibe yinto exhumanayo, imikhuba ye-orthodontic ingasebenzisa i-psychology yentsha ukuthuthukisa ukunamathela ezimisweni zokugqoka ezinqunyiwe.

Kungani ukukhetha okubonakalayo kubalulekile ekukhuthazeni intsha

Ubusha buyisigaba sokuthuthuka esibonakala ngesifiso esinamandla sokuzimela kanye nokuziveza. Ukwelashwa ngamazinyo, okuvame ukuphoqelelwa abazali futhi kwenziwe odokotela, ngokwemvelo kunciphisa lokhu kuzimela. Ukuvumela intsha ukuthi ikhethe imibala yama-ligatures ayo e-elastomeric (ama-O-rings) noma ama-interarch elastics kubuyisela izinga lokulawula. Izifundo zokuziphatha zezokwelapha zibonisa ukuthi ukunikeza izinketho ezincane, ezilawulwayo endaweni yokunakekelwa kwempilo kungaphakamisa amaphuzu okubandakanyeka kwesiguli afinyelela ku-40%.

Lokhu kukhetha okubonakalayo kuguqula umshini wokwelapha kusuka kudivayisi yezokwelapha kuphela ube yinto engenziwa ngokwezifiso. Iziguli zivame ukuvumelanisa ukukhetha kwazo imibala namaholide, imibala yesikole, noma izintandokazi zobuhle bomuntu siqu. Lokhu kuhlangana okuhle kunciphisa ukucwaswa nokukhungatheka okuvame ukuhlotshaniswa nemishini egxilile, okukhuthaza ukucabanga kwesiguli ngokubambisana kakhulu ngesikhathi sokulungiswa kwesihlalo nokunakekelwa ekhaya.

Indlela ukuthobela imithetho kuthinta ngayo ukusebenza kahle kokwelashwa

Ukusebenza kahle kwemishini yokwelashwa kwe-orthodontic kuhlobene ngqo nokusetshenziswa kwamandla okuqhubekayo. Kuma-elastic e-interarch, odokotela bavame ukunikeza amahora angama-20 kuya kwangu-22 okugqoka kwansuku zonke ukuze kufezwe ukunyakaza okuhle kwamazinyo. Lapho isisusa sincipha futhi isiguli sinciphisa isikhathi sokuguguleka sibe amahora ayi-12 noma ngaphansi, amandla e-biomechanical aba yizikhawu, okuholela ezigabeni zokuphumula kwamaseli ku-periodontal ligament kunokuvuselelwa kwamathambo okusebenzayo.

Lokhu kuntuleka kokuthobela imithetho kuhumusha ngokuqondile ukungasebenzi kahle kwezokwelapha. Ubude besikhathi sokwelashwa bunganda kalula ngezinyanga ezi-3 kuya kwezi-6 ngenxa yokuguga okungaguquki kwe-elastic, okudinga ama-aphoyintimenti engeziwe kanye nokwanda kwezindleko zokwelashwa. Ngokusebenzisa ama-elastic anemibala ukuze kugcinwe amazinga aphezulu okugqugquzelwa kwesiguli, odokotela bangaqinisekisa ukuthi impendulo yezinto eziphilayo emandleni asetshenziswayo ihlala ingaphazanyiswa, ngaleyo ndlela bagcine uhlelo lokwelashwa lusesimeni esifanele.

Izici Zezokwelapha Nezokuziphatha Ezibangela Ukusetshenziswa Okunwebekayo Okunemibala

Ukusetshenziswa kwe-elastomeric enemibala kudinga ukuqonda kokubili isayensi yezinto ezibonakalayo elawula imikhiqizo ye-polyurethane kanye nokuguquguquka kokuziphatha kwabantu abasebasha. Imikhiqizo ye-elastomeric itholakala kakhulu ku-orthodontics, kodwa izakhiwo zayo zemishini azishintshi. Ukuwohloka kwamandla kwama-ligatures namaketanga e-elastomeric ngokuvamile kufinyelela ku-50% kuya ku-70% emahoreni okuqala angu-24 okuchayeka emlonyeni.

Ngenxa yokuthi lezi zinto zidinga ukushintshwa njalo—ngokuvamile njalo emavikini ama-4 kuya kwayi-6 ukuze kufakwe ama-ligature kanye nansuku zonke ukuze kufakwe ama-interarch elastiki—isidingo esiphindaphindayo sama-elastomeric amasha sidala umjikelezo oqhubekayo wokuzibandakanya kwesiguli. Ukuqonda umehluko wezokwelapha phakathi kwale mikhiqizo kanye nezici zokuziphatha eziqhuba ukusetshenziswa kwayo kubalulekile ekwandiseni ukusebenza kahle kwe-biomechanical kanye nokuhambisana nesiguli.

Indlela ama-elastic anemibala ahluke ngayo kuma-ligatures nama-interarch elastics

Nakuba iziguli zivame ukusebenzisa igama elithi “ama-rubber bands” ngokushintshana, odokotela kumele bahlukanise phakathi kwama-elastomeric ligatures nama-interarch elastics lapho beklama isu lokuhambisana nemigomo. Ama-elastomeric ligatures (noma ama-O-rings) asetshenziswa udokotela ukuze aqinise ucingo lwe-arch ngaphakathi kwesikhala se-bracket. Ukukhetha kwabo imibala kunikeza ukukhulisa ubuhle futhi kwakha injabulo yokuqokwa, kodwa abadingi ukungenelela kwansuku zonke kwesiguli.

Ngakolunye uhlangothi, ama-interarch elastiki ayizibhande ezisuswayo ezisetshenziselwa ukulungisa ama-malocclusion njengokungafani kwe-Class II noma i-Class III. Lokhu kudinga ukuthobela ngokuqinile isiguli, njengoba isiguli kumele sizisuse ekudleni futhi sizishintshe kaningi ngosuku ngamabhande amasha ukuze silondoloze amazinga afanele amandla (ngokuvamile asukela kuma-ounces angu-2.5 kuya kwangu-6.0). Ukunikeza ama-interarch elastiki anemibala kusebenza njengesikhumbuzo esibonakalayo njalo sesiguli sokugcina isimiso saso sokugqoka nsuku zonke.

Yiziphi izici zengqondo neziseceleni kwesihlalo ezikhulisa ugqozi

Okuhlangenwe nakho okuseceleni kwesihlalo kudlala indima ebalulekile ekuqiniseni ukuthobela imithetho yesiguli. Lapho abasizi be-orthodontics bechitha imizuzu emi-2 kuya kwemi-3 bexoxa ngezinketho zemibala, kwakha ubuhlobo obubalulekile phakathi kwethimba lezokwelapha kanye nesiguli esisesincane. Lokhu kuqinisa okuhle kwenza isiguli samukele kakhudlwana imiyalelo yezokwelapha mayelana nokuhlanzeka komlomo kanye nokugqoka okunwebekayo.

Ngaphezu kwalokho, amasu okudlala angasetshenziswa. Imikhuba ivame ukuqhuba imincintiswano yesizini noma imikhankaso yezokuxhumana lapho iziguli zibonisa khona inhlanganisela yazo yemibala eyingqayizivele. Lokhu kuqinisekiswa kontanga kusebenzisa isifiso sentsha sokwamukelwa emphakathini, kuguqula ukuguguleka ngenkuthalo kwama-elastics anemibala kube ukuziphatha okuzuzisa umphakathi kunokuba kube umsebenzi ozimele.

Yimiphi imikhawulo kanye nezici zokukhetha amacala ezibalulekile

Naphezu kwezinzuzo zazo zokuziphatha, ama-elastomeric anemibala aveza imikhawulo ethile yezokwelapha. Ukwakheka kwezinto kuyisici esiyinhloko; kuyilapho iningi lama-ligature anemibala yesimanje lenziwai-polyurethane engeyona i-latexUkuze kugwenywe ukusabela kokungezwani komzimba, ama-elastic angewona ama-latex interarch avame ukukhombisa ukubola kwamandla okusheshayo kune-latex yemvelo. Odokotela bangase badinge ukunikeza ukwenyuka okungu-10% kuya ku-15% kwamandla okuqala kumabhande angewona ama-latex ukuze kulungiswe lokhu konakala okusheshayo.

Ukukhethwa kwekesi nakho kunquma ukuthi umbala uphila kahle yini. Ezimweni ezidinga ukulungiswa okunzima kokujikeleza noma lapho imishini yokushelela engenakho ukungqubuzana ibaluleke kakhulu,amabakaki azibophayonoma ama-ligature ensimbi engagqwali angase abe ngcono ngokwe-biomechanically kune-elastomeric ligatures. Ezimweni ezinjalo, udokotela kumele alinganisele isifiso sokuziphatha sama-ligatures anemibala ngokuhambisana nezidingo zemishini zesigaba sokwelashwa.

Ukuqhathanisa Izinketho Ezinemibala Nezingalingani Zokunwebeka

Lapho beklama uhlelo lokwelapha, odokotela bamazinyo kumele balinganise izinzuzo zokuziphatha zama-elastic anemibala ngokuqhathanisa nobuhle kanye nezakhiwo zezokwelapha zezinye izindlela ezingathathi hlangothi noma ezicacile. Ama-brackets obuhle (i-ceramic noma i-sapphire) avame ukubhangqwa nama-ligatures e-elastomeric acacile noma anombala wezinyo ukuze kuncishiswe ukubonakala kwemishini. Kodwa-ke, lezi zinketho ezingathathi hlangothi ziletha izinselele ezihlukile maqondana nokuzinza kwezinto kanye nokwaneliseka kwesiguli.

Amaketanga nama-ligature e-clear elastomeric asengozini enkulu yokushintsha umbala. Ucwaningo lubonisa ukuthi ama-elastomeric e-clear polyurethane angabonisa ushintsho lombala olubonakalayo (inani le-Delta E elingaphezu kuka-3.0) zingakapheli izinsuku eziyi-7 kuphela lapho evezwa kuma-chromogens okudla njengekhofi, itiye, i-mustard, noma i-turmeric. Lokhu kwehla okusheshayo kokubukeka kunganciphisa ukwaneliseka kwesiguli ngendlela exakile, okwenza ukuqhathanisa phakathi kwezinketho ezimibalabala nezingathathi hlangothi kube yinto ebalulekile yokucatshangelwa kwezokwelapha.

Yiziphi izinto eziqhathanisa kangcono ukuhambisana, ukubukeka, kanye nokupenda

Ukuhlola ukuhwebelana phakathi kwe-elastomeric enemibala nengathathi hlangothi kudinga ukuhlaziya ukusebenza kwayo kuzo zonke izilinganiso eziningana zezokwelapha nezokuziphatha. Ama-elastics anemibala afihla ngempumelelo ukudaya kokudla, kuyilapho izinketho ezicacile zikukhulisa. Ngaphezu kwalokho, izithasiselo ze-pigment kuma-elastomeric anemibala azishintshi kakhulu amaphrofayili azo okulethwa kwamandla uma kuqhathaniswa nezinguqulo ezingenambala, okuvumela odokotela ukuthi benze izinqumo ngokusekelwe kakhulu ekubukeni nasekuhambisaneni nemithetho esikhundleni sokuyekethisa kwe-biomechanical.

Lapho izinketho ezingathathi hlangothi zingaba yisinqumo esingcono

Naphezu kwezinzuzo zokuziphatha zezinketho ezinemibala, ama-elastic angathathi hlangothi noma acacile ahlala eyisinqumo esingcono kakhulu sezinhlobo ezithile zabantu kanye nezimo zezokwelapha. Iziguli ezindala ezisebenzisa amazinyo, ezivame ukubeka phambili ukukhetha kunokuveza, zikhetha kakhulu ama-ligature acacile ahambisana nama-bracket e-ceramic noma ukwelashwa okucacile kwe-aligner. Kulezi ziguli, ukuqina kwengqondo kuvela ekungabonakali kwensiza kunokwenza ngendlela oyifisayo.

Ngaphezu kwalokho, ezinye iziguli ezisencane ziyazethemba kakhulu futhi zikhetha indlela encane. Ezimweni lapho kusetshenziswa ama-ligature acacile kodwa ukudaya ukudla kuyinkinga eqhubekayo, odokotela bangase bashintshe ama-elastomere acacile ngama-ligature esiliva noma anombala womusi, noma bakhethe ama-Teflon-coated.izibopho zensimbi engagqwaliLezi zinketho zigcina iphrofayili engabonakali kahle ngenkathi zimelana nokushintsha kombala okusheshayo okuhlupha izinto ze-polyurethane ezisobala.

Indlela Imikhuba Yokwelapha Ama-Orthodontic Engayisebenzisa Ngayo Isu Lokukhetha Umbala

Ukuhlanganisa isu eliphelele lokukhetha umbala ekwelapheni kwamazinyo kudinga okungaphezu nje kokuthenga izinhlobo ezahlukene ze-elastomeric ligatures. Kudinga indlela ehlelekile yokusebenza, ukuphathwa kwempahla, kanye nokuxhumana kweziguli. Ngaphandle kwephrothokholi elula, ukukhetha imibala kungaphazamisa ukusebenza kwesihlalo, kudle isikhathi esibalulekile somtholampilo.

Iqoqo eliphethwe kahle lezinketho zemibala ezingu-20 kuya ku-30 ​​libiza izindleko ezincane ngesiguli ngasinye—ngokuvamile ngaphansi kuka-$0.15 ukuze kusetshenziswe ama-ligature ngomlomo wonke—kodwa kudinga ukulawulwa okuqinile kwesitoko ukuqinisekisa ukusebenza kahle kwezinto. Imikhiqizo ye-polyurethane iyazwela ezicini zemvelo, futhi ukugcinwa okungafanele kungaholela ekuwohlokeni kwamandla ngaphambi kwesikhathi ngaphambi kokuba ama-elastic abekwe emlonyeni wesiguli.

Indlela yokwakha iphrothokholi yokukhetha umbala

Ukuze kuvinjelwe ukukhethwa kombala ekudleni isikhathi esibalulekile sesihlalo, imikhuba kumele ihlanganise inqubo yokwenza izinqumo kusenesikhathi emsebenzini wesiguli. Imitholampilo eminingi eningi isebenzisa izinhlelo zokusebenza zedijithali zokukhetha imibala kumathebulethi egumbini lokulinda, okuvumela intsha ukuba ibone ngeso lengqondo futhi ikhethe imibala yayo ngaphambi kokuhlala esihlalweni samazinyo. Lolu shintsho olulula lokuphatha lungasindisa isilinganiso semizuzu emi-3 kuya kwemi-5 nge-aphoyintimenti ngayinye yokulungisa.

Ngaphandle kwalokho, izisebenzi zingasebenzisa "isondo lombala" elibonakalayo edeskini lokubulala inzalo noma lokubhalisa. Ngesikhathi umsizi we-orthodontic esekulungele ukususa ucingo, isiguli sesivele sikhethile. Le nqubo iqinisekisa ukuthi izinzuzo zokuziphatha zokukhetha umbala ziyafezeka ngaphandle kokunciphisa ukusebenza kahle kwesimiso sansuku zonke semtholampilo.

Yikuphi ukuxhumana okusebenza kahle kakhulu nentsha nabazali

Ukuxhumana okuphumelelayo kuguqula ukukhethwa kwama-elastic anemibala kusuka ekuthandweni nje kobuhle kube yisivumelwano sokuziphatha. Odokotela nabasebenzi kufanele bahlele ukuhlinzekwa kwama-elastic anemibala njengokubambisana. Umbhalo ojwayelekile uhilela ukutshela osemusha ukuthi, “Unesibopho sokukhetha imibala ukuze wenze ukumamatheka kwakho kubukeke kukuhle, kodwa wena unesibopho sokuwagqoka amahora angama-22 ngosuku ukuze ukwelashwa kusebenze.”

Ukubandakanya abazali kule ngxoxo kubaluleke ngokulinganayo. Abazali bavame ukuthwala umthwalo wezezimali wesikhathi eside sokwelashwa okubangelwa ukungalandeli imithetho. Ngokufundisa abazali ukuthi ama-elastic anemibala asebenza kanjani njengezinkomba ezibonakalayo zokuguguleka—okubenza bakwazi ukubona kalula ukuthi ingane yabo igqoke amabhande enjoloba ayinikiwe—lo mkhuba ubhalisa umzali njengomqaphi osebenzayo ohlelweni lokuthobela imithetho.

Indlela isitokwe kanye nokulawulwa kwekhwalithi okuthinta ngayo ukuhambisana

Ukugcina ububanzi obuhlukahlukene bemibala ye-elastomeric kudinga ukugadwa ngokucophelela kwempahla ekhona. Ama-elastomeric e-Orthodontic anempilo engapheli yeshelufu, ngokuvamile asukela ezinyangeni eziyi-18 kuya kwezingama-24, ngemva kwalokho amaketanga e-polyurethane aqala ukuhlangana ngendlela engafanele, okuholela ekubeni buthakathaka kanye nephrofayili yokulethwa kwamandla engalindelekile. Imikhuba kumele isebenzise uhlelo lwempahla oluqala ukungena, oluphuma kuqala (FIFO) ukuze kuncishiswe ukuphelelwa yisikhathi kwezinto.

Ngaphezu kwalokho,ukulawulwa kwekhwalithi kudlulela ezimweni zokugcinaImikhiqizo ye-Elastomeric ibucayi kakhulu ekukhanyeni kwe-ultraviolet (UV) kanye nokushintshashintsha kwezinga lokushisa okukhulu. Impahla kufanele igcinwe ezitsheni ezingacacile noma kumakhabethe amnyama, kude nokukhanya kwelanga okuqondile kanye nokushisa okuzenzakalelayo, ukuze kulondolozwe ubuqotho besakhiwo kanye nokuqina kwama-polymer.

Indlela Yokulinganisa Ukuthi Ama-Elastics Anemibala Akufanele Yini Ukunikezwa

Ukuze kuqinisekiswe umzamo wokuphatha uhlu olubanzi lwe-elastomeric enemibala, imikhuba yokwelapha ama-orthodontic kumele ihlole imbuyiselo ekutshalweni kwezimali (ROI) ngokusebenzisa izilinganiso zezokwelapha nezokusebenza eziqondile. Nakuba izindleko zangaphambilini zama-ligature nama-band anemibala zincane, inani langempela lalokhu kungenelela kokuziphatha lilinganiswa ngomthelela wako ekusebenzeni kahle kokwelashwa kanye nokugcinwa kwesiguli.

Ngokulandela izinkomba zokuthobela imithetho ngendlela ehlelekile,

Izinto Ezibalulekile Okufanele Uzicabangele

• Iziphetho ezibaluleke kakhulu kanye nesizathu seziguli ze-Orthodontic
• Imininingwane, ukuhambisana, kanye nokuhlolwa kwengozi okufanele kuqinisekiswe ngaphambi kokuthi uzibophezele
• Izinyathelo ezilandelayo ezisebenzayo kanye nezixwayiso abafundi abangazisebenzisa ngokushesha
