Isingeniso
Nakuba zombili ziyizingxenye ezinwebekayo ezisetshenziswa ngama-braces, amaketanga kagesi kanye nama-ligature e-elastomeric aklanyelwe imisebenzi ehlukene futhi akhiqize imiphumela ehlukene yokwelapha. Esinye sisebenza njengesixhumi esiqhubekayo esingasiza ukuvala izikhala futhi sisebenzise amandla abanzi emazinyweni amaningi, kanti esinye siqinisa i-archwire kuma-bracket ngamanye ngokulawula okusendaweni. Ukuqonda lowo mehluko kusiza ukucacisa ukuthi kungani odokotela bamazinyo bekhetha esinye kunesinye ezigabeni ezahlukene zokwelashwa. Lesi sihloko sichaza ukuthi into ngayinye ihlelwe kanjani, ukuthi isebenza kanjani ngokwezokwelapha, nokuthi lokho kungafani kusho ukuthini ngokunyakaza kwamazinyo, ukungqubuzana, isikhathi sokuqokwa, kanye nokusebenza kahle kokwelashwa okuphelele.
Kungani Amaketanga Amandla vs Ama-Ligature Elastomeric Ebalulekile
Ukukhethwa kwezindlela zokubopha kuthonya ngqo ukusebenza kahle kwezihlalo ze-archwire, i-space closure mechanics, kanye nobude besikhathi sokwelashwa (ngokuvamile esithatha izinyanga ezingu-18 kuya kwezingu-24) ku-orthodontics yesimanje. Nakuba zombili izintambo zamandla ze-orthodontic kanye ne-elastomeric ligatures zifeza injongo eyisisekelo yokubopha i-archwire endaweni ye-bracket, imiklamo yazo ehlukile yesakhiwo inquma izindima ezihlukene ngokuphelele ze-biomechanical. Ukuqonda lo mehluko kubalulekile ekwenzeni ngcono imiphumela yezokwelapha kanye nokuphatha isitokwe ngempumelelo emikhubeni yamazinyo ephezulu.
Abaqondisi bemitholampilo kanye nabaphathi bokuthengwa kwempahla kumele bahlole amaphrofayili athile okulethwa ngamandla kwale mikhiqizo ngokuqhathanisa nezindleko zabo zezinto ezibonakalayo. Ukwenza ukukhetha okufanele phakathiamaketanga e-elastic aqhubekayokanye nokufakwa kwamazinyo ngakunye kuqinisekisa ukuthi ukunyakaza kwamazinyo kuyaqhubeka ngendlela ebikezelwayo, kugwema ukubambezeleka kokwelashwa okungadingekile noma isidingo sokubonana nodokotela njalo.
Umthelela wezokwelapha kanye nokusebenza
Ukukhetha phakathi kwamaketanga aqhubekayo nama-ligature ngamanye kunomthelela olinganisekayo kokubili ekusebenzeni kahle kwezokwelapha kanye nokusebenza komsebenzi. Ngokombono wezokwelapha, ukukhetha umkhiqizo we-elastomeric ofanele kuqinisekisa ukunyakaza kwamazinyo okubikezelwayo phakathi nezikhawu ezijwayelekile zokuqokwa kwamasonto ama-4 kuya kwayi-6. Ukusetshenziswa okungalungile—njengokusebenzisa iketanga lamandla lapho kudingeka i-ligation ngayinye—kungabangela ukungqubuzana okungafuneki (ngokuvamile kwandisa ukumelana ngamagremu angu-50 kuya kwayi-100), okungenzeka kwehlise ijubane lesigaba sokulinganisa nokulinganisa ngamasonto ambalwa.
Ngokwemisebenzi, ukwenza kube ngokwejwayelekile ukusetshenziswa kwalezi zinto kunganciphisa isikhathi sesihlalo ngo-10% kuya ku-15% (cishe imizuzu emi-3 kuya kwemi-5 ngokuvakasha okuvamile kwemizuzu engama-30). Lapho abasizi bamazinyo nodokotela bamazinyo benezinqubo ezicacile zokuthi kufanele basebenzise nini i-athikili ethile.Amaketanga Amandla E-Orthodontic, ukushintshwa kwempahla esitokweni kuba lula ukubikezela, kunciphisa imfucuza futhi kuvimbele ukuphela kwempahla ebalulekile.
Amacala abalulekile okusetshenziswa ekwelapheni amazinyo
Ukwelashwa ngamazinyo kuhlukaniswe kabanzi ngezigaba ezihlukene, ngasinye sidinga amasu athile okubopha. Ngesikhathi sokuqala sokulinganisa nokulungisa, lapho kudingeka khona amandla alula, aqhubekayo ukuze kulungiswe ukuminyana okukhulu,ama-ligature e-elastomeric ngamanyeziyizindinganiso. Zivikela izintambo ze-arch ze-nickel-titanium (NiTi) eziguquguqukayo kakhulu (ngokuvamile ezingamasentimitha angu-0.012 kuya kwangu-0.016 ububanzi) ezikhaleni zama-bracket ngenkathi zivumela izinga elidingekayo lemishini yokushelela.
Ngakolunye uhlangothi, isigaba sokuvala isikhala sincike kakhulu ekulethweni kwamandla okuqhubekayo kwamaketanga kagesi. Lapho odokotela bamazinyo bedinga ukuhlanganisa izikhala ngemva kokukhipha (ngokuvamile ukuphatha izikhala ezingu-5mm kuya ku-7mm) noma ukuvala ama-diastemas ajwayelekile, amaketanga ahlinzeka ngamandla adingekayo ahambisanayo emazinyweni amaningi ukuze kufezwe amazinga okuvala isikhala aphakathi kuka-0.5mm kuya ku-1.0mm ngenyanga. Uhlobo oluqhubekayo lwe-elastomer lusebenza njengohlelo lwamandla asebenzayo kunokuba nje indlela yokugcina engasebenzi, okwenza kube yinto ebalulekile ezigabeni eziphakathi nezokugcina zokwelashwa.
Yiziphi Izintambo Zamandla kanye Nezinhlayiya Ze-Elastomeric
Zombili izintambo zamandla kanye nama-ligature ngamanye angamalungu omndeni ofanayo wama-elastomer asekelwe ku-polyurethane, kodwa ukwakheka kwawo kwesakhiwo kuklanyelwe ukufeza izinjongo ezihlukile ze-biomechanical. Izinqubo zawo zokukhiqiza zifaka phakathi ukubumba ngomjovo noma ukukhipha okuqhubekayo ukudala imikhiqizo ekwazi ukugcina ukucindezeleka endaweni enzima, enomswakama womlomo (ngokuvamile engu-37°C kanye nomswakama ocishe ube ngu-100%).
Ukuqonda imininingwane engokwenyama yalezi zinto kuvumela odokotela ukuthi babikezele ukuthi bazosebenza kanjani phakathi nesikhathi sokulungisa. I-geometry engokwenyama ye-elastomer ayisho nje kuphela ukuthi isetshenziswa kanjani kodwa futhi nobukhulu bamandla ezowasebenzisa lapho isebenza.
Umklamo kanye nezicelo ezijwayelekile
Ama-ligature e-Elastomeric akhiqizwa njenge-single, discrete O-rings. Ngokuvamile ane-diameter yangaphandle esukela ku-0.110 kuya ku-0.120 inches, i-diameter yangaphakathi engaba ngu-0.040 kuya ku-0.050 inches, kanye nobukhulu obungu-0.030 kuya ku-0.035 inches. I-application yawo eyinhloko ukugqagqana phezu kwamaphiko amane okubopha e-twin bracket ejwayelekile, ebambe i-archwire iqine endaweni yayo. Ngokuvamile anikezwa ngezinduku ezibunjiwe noma ezindongeni, ephethe amamojula ayi-10 kuya kwangu-24 ngalinye, okwenza kube lula ukusebenzisa ngokushesha kusetshenziswa i-hemostat noma umqondisi we-ligature okhethekile.
Ngakolunye uhlangothi, amaketanga kagesi aqukethe umugqa oqhubekayo wamamojula e-elastomeric axhunyiwe. Ngokuvamile akhishwa kusuka ku-spool engamamitha angu-15. Umklamo uvumela udokotela ukuthi asike ubude obuqondile obudingekayo ukuze budlule emazinyweni amaningi. Ngokwelula iketanga kusuka kwelinye ibhuleki liye kwelinye, i-elastomer igcina amandla angaba khona, akhishwa kancane kancane ukuze adonse amazinyo ndawonye.
Izici zezinto ezibonakalayo kanye namandla
Izinto eziyisisekelo zemikhiqizo yomibili ngokuvamile ziyi-i-thermoplastic polyurethane yezinga lezokwelapha, ekhethwe ngenxa yokuqina kwayo okuphezulu, ukumelana nokudabuka, kanye nokuqina okujwayelekile kwe-Shore A okungu-80 kuya ku-90. Kodwa-ke, izici zamandla zincike kakhulu ekwakhiweni kwezinto kanye ne-geometry ethile yomkhiqizo. Ulwazi mayelana nezincazelo zezinto lungatholakala ngokubukeza imibhalo evela kubakhiqizi be-Ama-Ligature e-Elastomeric.
Isici esibalulekile sanoma iyiphi i-elastomer yamazinyo yiphrofayili yayo yokubola kwamandla. Uma inwetshiwe, izibopho ze-polyurethane ziqala ukukhululeka. Kuye ngobukhulu kanye nenqubo yokubopha eqondene nezinto, uchungechunge lwamandla olujwayelekile lungaletha amandla okuqala angamagremu angu-300 kuya kwangu-400 uma lunwetshiwe kabili ubude balo bokuphumula. Ama-ligature ngamanye anamandla okuhlala aphansi kakhulu, ngokuvamile aphakathi kwamagremu ayi-100 nama-200, okwanele ukubamba ucingo ngaphandle kokulubopha ngokuphelele.
Umehluko omkhulu ngokubuka nje
Umehluko ovelele kakhulu usekuhlukaneni kwamamojula. Ama-ligature ngamanye awanasikhala, njengoba engaxhunywanga. Amaketanga kagesi akhiqizwa ngezikhawu ezintathu ezijwayelekile ze-filament: avaliwe (akukho sikhala phakathi kwamasongo, cishe ama-2.8mm ukusuka enkabeni kuya enkabeni), amafushane (i-filament encane exhumanisayo, cishe ama-3.5mm), kanye namade (i-filament exhumanisayo ende, cishe ama-4.0mm).
| Ukucushwa | Isikhala (Kusuka Ephakathi Kuya Ephakathi) | Isicelo Esijwayelekile | Iphrofayili Yokulethwa Ngenkani |
|---|---|---|---|
| I-Ligature Yomuntu Ngamunye | Akukho (Okuhlukile) | Ukulinganisa/ukulinganisa kokuqala | Phansi (100-200g), ingasebenzi |
| Uchungechunge Oluvaliwe | ~2.8mm | Amabhuleki amancane, izinsika ezingezansi | Amandla okuqala aphezulu, ukubola okusheshayo |
| Uchungechunge Olufushane | ~3.5mm | Amabhuleki amabili ajwayelekile | Amandla aphakathi, ukubola okuqhubekayo |
| Uchungechunge Olude | ~4.0mm | Amabhuleki amakhulu, amabhuleki e-ceramic | Amandla alula, aqhubekayo |
Odokotela bakhetha isikhala ngokusekelwe ebangeni eliphakathi kwama-bracket kanye nenani lamandla afunwayo. Uchungechunge oluvaliwe kuma-bracket amakhulu luzonwebeka kakhulu, lunikeze amandla aphezulu, kanti uchungechunge olude olusemazinyweni afanayo luzonikeza amandla alula kakhulu, aqhubekayo. Ama-ligature ngamanye, angenazo izixhumanisi eziphakathi kwama-bracket, awasebenzisi amandla aphakathi kwama-proximal.
Ukuqhathanisa Kanjani Amaketanga Amandla vs Ama-Ligature Elastomeric
Ukuhlola ukusebenza kwalezi zindlela ezimbili zokubopha kudinga ukuhlaziywa kokuwohloka kwamandla ngokuhamba kwesikhathi, izici zokuphatha emtholampilo, kanye nomnotho wokuthengwa kwempahla. Ngenxa yokuthi ama-aphoyintimenti e-orthodontic ngokuvamile ahlukaniswa ngamasonto ama-4 kuya kwayi-8, izinto ezikhethiwe kumele zisebenze kahle phakathi nesikhathi sonke ngaphandle kokudinga ukushintshwa ngaphambi kwesikhathi.
Nakuba yomibili imikhiqizo ihlushwa ukulinganiselwa okungokwemvelo kwe-polyurethane endaweni emanzi, ukusetshenziswa kwayo okuhlukile kusho ukuthi lokhu kulinganiselwa kubonakala ngendlela ehlukile emtholampilo. Ukuqhathanisa okuphelele kugqamisa ukuhwebelana phakathi kokugcinwa kwamandla, ukuthobela imithetho yesiguli, kanye nokuphathwa kochungechunge lokuhlinzekwa.
Ukugcinwa nokusebenza okuphoqelelayo
Kokubili amaketanga kagesi kanye nama-elastomeric ligatures abonisa ukubola kwamandla okuqala okusheshayo. Izifundo zemitholampilo zibonisa njalo ukuthi ama-polyurethane elastomer alahlekelwa phakathi kuka-50% no-70% wamandla awo okuqala emahoreni okuqala angu-24 okusetshenziswa emlonyeni. Ngemva kwalokhu kwehla kokuqala, izinga lamandla liyancipha, ligcina cishe u-30% kuya ku-40% (cishe amagremu ayi-100 kuya ku-150) wamandla awo okuqala emavikini amathathu kuya kwamane asele.
Ngenxa yokuthi amaketanga kagesi ashukumisa amazinyo ngenkuthalo, lokhu kubola kwamandla kumele kuphathwe ngokucophelela. Uma iketanga leluliwe kakhulu ekuqaleni ukuze kulungiswe ukubola, lingabangela i-hyalinization ye-periodontal ligament, okumisa ukunyakaza kwamazinyo. Ama-ligature ngamanye, asebenza ngokuyinhloko njengezinto zokugcina ezingasebenzi, awathinteki kakhulu kulokhu kubola, uma nje egcina amandla anele okugcina i-archwire ibambeke ngokugcwele endaweni yokubamba izibambo.
Ukuphatha, ukuqina, kanye nokucabangela isiguli
Ukuphathwa nokuqina kuthonywa kakhulu ukudla kwesiguli kanye nokuhlanzeka komlomo. Zombili izinto zisengozini yokungcoliswa yikhofi, itiye, i-turmeric, kanye nokubhema. Kodwa-ke, ngenxa yokuthi izintambo zikagesi zimboza indawo enkulu futhi zidlula izikhala eziphakathi, zithambekele kakhulu ekubambeni i-plaque kanye nokungcola kokudla uma kuqhathaniswa nama-ligature ahlukene.
Ukuqina nakho kuyimbangela, njengoba amazinga okuphuka kwesikhumba ngokuvamile engaphansi kuka-2% kuya ku-3% ngenyanga kuma-elastomer asezingeni eliphezulu. I-ligature yomuntu ngamunye ephukile ithinta izinyo elilodwa kuphela, mhlawumbe ivumela ucingo ukuthi luphume ebhokisini elilodwa. Nokho, uchungechunge lwamandla oluqhekekile lulimaza ngokuphelele indlela yokuvala isikhala yonke ikota, okudinga ukuvakashelwa okuphuthumayo ngokushesha ukuze kuvinjelwe ukubuyela emuva.
Izindleko kanye nokucatshangelwa kokuhlinzekwa
Ngokombono wokuthengwa, izakhiwo zezindleko zihluka kakhulu. Ngezikhathi ezijwayelekile zokuhola umhlinzeki zamaviki ama-2 kuya kwangama-4, i-spool ejwayelekile engamafidi ayi-15 ye-orthodontic power chain ivame ukubiza phakathi kuka-$10 no-$18, kuye ngokuthi umenzi kanye nezinga lezinto ezibonakalayo. I-spool eyodwa inganakekela iziguli eziningi. Ngokuphambene nalokho, ama-ligature e-elastomeric ngamanye ngokuvamile athengiswa ngamaphakethe ayi-1,000 (ngokuvamile izinti eziyi-100 zezinti eziyi-10), kusukela ku-$5 kuya ku-$12 ngephakethe ngalinye.
| Isici | Amaketanga Amandla E-Orthodontic | Ama-Ligature e-Elastomeric |
|---|---|---|
| Umsebenzi Oyinhloko | Ukuvalwa kwesikhala esisebenzayo nokuhlanganiswa | Ukuzibandakanya kwe-archwire engasebenzi |
| Ukulethwa Kwamandla Kokuqala | Amagremu angu-300 – 400 (ahlukahluka ngokwezinga) | Amagremu ayi-100 – 200 |
| Ukubola Kwamandla (amahora angu-24) | 50% – 70% | 50% – 70% |
| Isisekelo Sezindleko Ezijwayelekile | $10 – $18 nge-spool engamafidi angu-15 | $5 – $12 ngephakethe ngalinye labantu abayi-1,000 |
| Inselele Yokuhlanzeka | Okuphezulu (kudlulela izikhala eziphakathi nendawo) | Okuphansi (ukubekwa okuqondile) |
Nakuba izindleko zesiguli ngasinye zezinto zombili ziphansi kakhulu (ngokuvamile zingaphansi kuka-$0.50 nge-arch), imitholampilo eningi kakhulu kumele icabangele izindleko ezihlanganisiwe, njengoba ama-elastomer angaba ngu-5% kuya ku-8% wezindleko eziphelele ezisetshenziswayo. Ukulinganisa isitokwe kumikhiqizo embalwa ethembekile nemibala kunganciphisa kakhulu izindleko ezikhokhwayo futhi kube lula ukuhamba kwempahla.
Lokho Abathengi Nodokotela Okufanele Bakuhlole
Abaphathi bokuthengwa kwempahla kanye nabaqondisi bezokwelapha kumele balinganisele ukusebenza kahle kwe-biomechanical kanye nokuhlelwa kwempahla kanye nokuhambisana nemithetho. Ukuthola ama-elastomer e-orthodontic akuyona nje indaba yokuthola intengo ephansi kakhulu; kudinga ukuhlolwa okujulile kwemininingwane yomkhiqizo, ukuphepha kwezinto ezibonakalayo, kanye nokuthembeka komthengisi.
Ukusungula izinqubo zokusebenza ezijwayelekile zokuthenga kuqinisekisa ukuthi abasebenzi bezokwelapha bahlala benokufinyelela ezintweni ezisebenza ngendlela ebikezelwayo. Lokhu kudinga indlela ehlelekile yokuhlola imikhiqizo emisha ngaphambi kokuzibophezela ekuthengeni okuningi kwezikhungo.
Imininingwane yomkhiqizo kanye nokupakishwa
Lapho behlola imininingwane yomkhiqizo, abathengi kumele bahlole ukuvumelana kobukhulu bama-elastomer. Kuma-ligature ngamanye, ukunwebeka kumele kuvumele ukwelulwa phezu kwama-bracket amakhulu amabili ngaphandle kokuqhekeka, kuyilapho kubuyela kububanzi obuqinile ukuqinisekisa ukuhlala kwentambo egcwele. Abathengi kufanele baqinisekise ububanzi bangaphakathi nangaphandle obuqondile ukuqinisekisa ukuhambisana nezinhlelo zabo zama-bracket abazithandayo.
Kumaketanga kagesi, ukunemba kwesikhala sentambo (esivaliwe, esifushane, eside) kubalulekile. Isikhala esingaguquki eceleni kwe-spool eyodwa siholela ekulethweni kwamandla okungalindelekile, okwenza kube nzima ukuhlela ukwelashwa. Ukupakishwa kubaluleke ngokulinganayo; ama-spool kumele agcinwe kuma-dispenser angangenisi ukukhanya ukuze kuvinjelwe ukuwohloka kwangaphambi kwesikhathi (i-polyurethane ingonakala ngo-20% uma ivezwa ekukhanyeni kwe-UV okuqondile isikhathi esingaphezu kwamahora angu-48), kuyilapho ama-ligature kufanele apakishwe ezikhwameni ezivaliwe, ezingangenisi umswakama.
Ikhwalithi, ukuhambisana kwezinto eziphilayo, kanye nokulandelela
Ukuqinisekiswa kwekhwalithi kanye nokuhambisana kwezinto eziphilayo akunakuxoxiswana ngakho ekuthengweni kwamazinyo. Yonke imikhiqizo ye-elastomeric kumele ihambisane nezindinganiso ze-ISO 10993-1 kanye ne-ISO 10993-5 (cytotoxicity) zokuhlolwa kwezinto eziphilayo kwamadivayisi ezokwelapha. Ngaphezu kwalokho, amafomula angenayo i-latex manje ayindinganiso embonini futhi ayadingeka kakhulu ezindaweni eziningi. Njengoba kulinganiselwa ukuthi i-1% kuya ku-6% yabantu abavamile babonisa ukuzwela kwe-latex, ukusebenzisa ama-polyurethane angenayo i-latex kususa ingozi yokusabela okukhulu kokungezwani komzimba.
Ukulandelela kungenye into ebalulekile. Abakhiqizi abadumile banikeza izinombolo zezindawo kanye nezinsuku zokuphelelwa yisikhathi (okubonisa impilo ejwayelekile yeshelufu yezinyanga ezingama-24 kuya kwezingama-36) kuzo zonke izingqwembe. Lokhu kuvumela imitholampilo ukulandelela imijikelezo yokuphila kwempahla kanye nokuphatha ukubuyiselwa kwemali uma kudingeka. Imitholampilo efuna ukuqinisekisa izitifiketi zabahlinzeki kanye nezinqubo zokulawula ikhwalithi kufanele iqondise imibuzo ngeziteshi ezisemthethweni, njengokuthiukuxhumana nabaphakelingeAmaketanga Amandla E-Orthodonticama-portals ukuze acele imibhalo yokuthobela imithetho.
Izinyathelo zokulinga kanye nokulinganisa
Ngaphambi kokwenza uhlobo olusha lwe-power chain noma i-ligature lube yi-standard emtholampilo onezihlalo eziningi, kunconywa kakhulu ukuthi kwenziwe isivivinyo sezokwelapha esilinganiselwe sezinsuku ezingama-60 kuya kwezingama-90.
