Ama-bracket azenzela wona ashintshe ukwelashwa kwe-orthodontic eminyakeni engamashumi amabili edlule. Ngokungafani nama-bracket endabuko adinga ama-ligature anwebekayo noma e-wire ukuze aqinise i-archwire, ama-bracket azenzela wona afaka isango noma indlela yokuslayida eyakhelwe ngaphakathi. Lo mklamo unciphisa ukungqubuzana, ufinyeza izikhathi zokuqokwa, futhi uthuthukisa induduzo yesiguli. Ngokusho kwe-American Association of Orthodontists (AAO), cishe iziguli eziyizigidi ezine e-United States zithola ukwelashwa kwe-orthodontic minyaka yonke, kanti izinhlelo ezizenzela wona zibangela inani elikhulayo lamacala. Imikhuba yokusebenzisa ama-bracket azenzela wona ibika ukuthi kunciphisa isikhathi esimaphakathi sesihlalo ngesiguli ngasinye ngemizuzu eyi-15-20 ngokuvakashelwa ngakunye.
Lo mhlahlandlela uhlola izici ezibalulekile okufanele odokotela bamazinyo kanye nezikhungo zamazinyo bazihlole lapho bekhetha amabhuleki azibopha wona, ahlanganisa umehluko womklamo wemishini, idatha yokusebenza kwemitholampilo, imininingwane yezinto ezibonakalayo, kanye nokucatshangelwa kokusebenzisa kahle izindleko.
Ayini Ama-Brackets Azibophayo Futhi Asebenza Kanjani?
Amabhulakhethi azibophayo ayimishini yokwelapha ehlonyiswe ngendlela yokukhiya ehlanganisa ngqo ucingo lwe-arch ngaphandle kokudinga ama-ligature angaphandle. Umzimba webhulakhethi unesiqeshana esinyakazayo, isango, noma isiphethu esingavulwa ukuze kufakwe ucingo bese luvalwa ukuze luboshwe endaweni evulekile.
Kunezinhlobo ezimbili eziyinhloko zemishini:
Amabhuleki azibophayo angenzi luthoinesivalo esiqinile, esingaguquki esingasebenzisi amandla asebenzayo ku-archwire. Indlela yokushelela igcina ukuhlangana okuxekethile nentambo, okunciphisa ukumelana kokukhuhlana ngesikhathi sokunyakaza kwamazinyo e-orthodontic. Lo mklamo ufaneleke kakhulu ezigabeni zokuhoxa kanye nezimo ezidinga imishini yokushelela esebenza kahle.
Amabhuleki asebenzayo azimelefaka isiqeshana noma umnyango onesipilingi ophethe ingcindezi yokuxhumana okulula ku-archwire. Uma intambo incane kunobukhulu besikhala, intwasahlobo ibamba intambo ngenkuthalo, inikeze amandla okuqondanisa acacile ezigabeni zokuqala zokwelashwa.
Ukubuyekezwa okuhlelekile kuka-2019 okushicilelwe ku-Intuthuko Kwezokwelapha Ama-OrthodonticsIjenali ithole ukuthi izinhlelo ezingasebenzi zikhiqiza njalo amandla okungqubuzana aphansi (ngokuvamile aphansi ngo-50-200gf kuzo zonke izinhlanganisela ze-wire/bracket ezivivinyiwe) kuyilapho izinhlelo ezisebenzayo zibonise ukuhambisana kokuqala okusheshayo ezimweni zokuminyana okuncane kuya kokuphakathi.
Kungani Amabhrakhethi Azibophayo Enciphisa Isikhathi Sokwelashwa Nokuvakashelwa Kwezihlalo
Enye yezinzuzo ezicashunwe kakhulu zokuzibopha ngama-bracket ukunciphisa isikhathi sokwelashwa kanye nenani lama-aphoyintimenti adingekayo. Izifundo zemitholampilo zinikeza idatha ethokozisayo:
- Isivivinyo esingahleliwe esingahlelelwe sibike ukunciphisa isikhathi sokwelashwa okumaphakathi cishe izinyanga eziyi-6 emacaleni aphelele asebenzisa izinhlelo zokuzibopha ezingasebenzi uma kuqhathaniswa namabhuleki amabili avamile.
- Izikhawu zokuqokwa zivame ukwelulwa kusukela emavikini ama-4 kuya emavikini ayi-6-8 ezimweni eziningi ngenxa yokulethwa kwamandla okuqhubekayo kanye nokungqubuzana okunciphile.
- Ukususwa kokubekwa kwe-ligature nokususwa kwayo kusindisa cishe imizuzu emi-5-8 nge-arch ngayinye ngesikhathi sokuqokwa, ngokusho kocwaningo lwesikhathi olwenziwe ezikoleni zamazinyo zaseyunivesithi.
Indlela yokusebenza yalokhu kuthuthukiswa igxile ekunciphiseni ukungqubuzana. Ezinhlelweni ezivamile, ama-ligatures anwebekayo adala ukubopha phakathi kwesikhala se-bracket kanye ne-archwire, ikakhulukazi ngesikhathi sokushelela. Izinhlelo ezizibophayo ezizibophayo zinciphisa lokhu kungqubuzana ngamaphesenti afinyelela ku-60-80, okuvumela amandla aqhubekayo alula ukuhambisa amazinyo ngempumelelo ngethambo le-alveolar.
Izinto Ezibalulekile: 17-4 Insimbi Engagqwali vs. Ubuchwepheshe be-MIM kuma-Brackets e-Orthodontic
Amabhuleki amaningi azimele athengiswayo akhiqizwa ngensimbi engagqwali noma i-metal injection molding (MIM). Ukuqonda lezi zinqubo kusiza ekuthengeni izinqumo zama-laboratory amazinyo kanye nemikhuba yokwelapha amazinyo.
Insimbi engagqwali engu-17-4iyi-alloy yokuqinisa imvula equkethe i-chromium (16-18%), i-nickel (3-5%), ithusi (3-5%), kanye ne-niobium. Amandla ayo okukhiqiza angaba ngu-1,000-1,200 MPa ayenza imelane kakhulu nokuguquguquka ngaphansi komthwalo we-orthodontic. Le nto inenzuzo ikakhulukazi kubakaki ababhekene nezilinganiso eziphakeme ze-moment-to-force ngesikhathi sokuvezwa kwe-torque.
Ukubumba Umjovo Wensimbi (MIM)kuyinqubo yokukhiqiza ecishe ibe yinethi ehlanganisa insimbi eyimpuphu nesistimu yokubopha. Inhlanganisela ifakwa ezikhumbeni ezinembile, bese ikhishwa bese ishiswa. Izingxenye ze-MIM zibonisa ukuhambisana okuhle kakhulu kobukhulu (+/- 0.02mm ukubekezelelana), okubalulekile ekunembeni kobukhulu besikhala kuma-bracket azimele. Ngokusho kocwaningo olushicilelwe ku-Ijenali Yobunjiniyela Bezinto Zokusebenza Nokusebenza, insimbi engagqwali engu-17-4 ecutshungulwe yi-MIM ithola izakhiwo zemishini ezifana nezinto ezibunjiwe ngemva kokucwiliswa kahle.
Abakhiqizi abasebenzisa ubuchwepheshe be-MIM babika amandla okukhiqiza amasonto onke angamayunithi angaphezu kuka-10,000 e-bracket ngomugqa ngamunye wokukhiqiza, okuvumela ukulawulwa kwekhwalithi okuqhubekayo kanye namanani okuncintisana okuthengwa ngobuningi.
Ukuqhathanisa Izinhlelo Zokuzibopha: Izitayela Zomuthi KaRoth vs. MBT
Imithi emibili ye-orthodontic ebhekiselwa kakhulu ilawula imakethe yezibambo ezizibophayo: incazelo ye-Roth kanye nencazelo ye-MBT (McLaughlin, Bennett, Trevisi). Zombili zichaza amanani e-torque, tip, kanye ne-angulation akhelwe endaweni ngayinye yezibambo.
| Ipharamitha | Udokotela kaRoth | Ukunikezwa Kwemithi Kadokotela kwe-MBT |
|---|---|---|
| I-Torque Ephezulu Ephakathi Ye-Incisor | +12° | +17° |
| I-Torque Engaphezulu Ye-Lateral Incisor | +8° | +10° |
| Ithiphu Eliphezulu Eliphakathi Le-Incisor | +5° | +4° |
| Ukusetshenziswa Okunconyiwe | Ukuqedela kwakudala | Isebenziseka ngezindlela eziningi, ithandwa odokotela abaningi |
Imithi kaRoth yasungulwa nguDkt. Ronald Roth ngawo-1970 futhi igcizelela ukulungiswa ngokweqile ukuze kubhekwe ukuthambekela kokubuyela emuva. Imithi kadokotela ye-MBT yavela ekuthuthukisweni okuhlelekile futhi inikeza ukubonakaliswa okukhulu kwe-torque engxenyeni engaphambili. Imigqa eminingi yanamuhla yama-bracket ezibophayo inikeza imithi kadokotela yomibili kulo lonke uhla lwemikhiqizo yayo.
Ukukhetha kwezokwelapha kuvame ukuxhomeka kufilosofi yokwelashwa komuntu ngamunye, lapho i-MBT ithola ukwamukelwa okubanzi emisebenzini yanamuhla ngenxa yokusebenza kwayo okubhaliwe kuzo zonke izinhlobo ezahlukene ze-malocclusion.
Indlela Yokuhlanganisa Amabhuleki Azibophezele Ekuqhubekeni Kwakho Komsebenzi Wokuzijwayeza
Ukushintshela ezinhlelweni zama-bracket ezizibophayo kudinga ukucatshangelwa kwezinqubo zezokwelapha, ukuqeqeshwa kwabasebenzi, kanye nokuphathwa kwempahla.
Isinyathelo 1: Hlola Izindlela Zokukhetha Icala.Ama-bracket azenzela wona asebenza kahle kakhulu ezimweni ezidinga indlela yokushelela esebenza kahle: ukuvalwa kwesikhala, ukulungiswa kwe-archwire, kanye nesisombululo esimaphakathi sokuminyana. Izidingo ze-torque eziyinkimbinkimbi noma ukujikeleza okunzima kungase kuzuze ezintweni ezivamile ezisizayo.
Isinyathelo 2: Qeqesha Abasebenzi Bezokwelapha Ngokusebenza Kwemishini.Ngokungafani nama-bracket avamile adinga ukubekwa kwe-ligature, ama-bracket azimele adinga amasu athile okuvula nokuvala. Ukuqeqeshwa okusebenzayo ngama-kit okubonisa anikezwa ngumkhiqizi kunciphisa amaphutha aseceleni kwesihlalo ngesikhathi sokusetshenziswa kokuqala.
Isinyathelo 3: Lungisa Izikhawu Zokuhlela Ama-aphoyintimenti.Imikhuba ivame ukwandisa izikhawu zokukhumbula kuze kube amasonto ayi-6-8 uma kusetshenziswa izinhlelo zokuzibopha ezingasebenzi, njengoba ukubola kwamandla kuhamba kancane futhi ukunyakaza kwamazinyo kuqhubeka njalo ngaphandle kokuphazamiseka okuhlobene nokungqubuzana.
Isinyathelo 4: Qapha i-Inventory kanye ne-Reorder Cycles.Ama-bracket azenzela wona ngokuvamile anezindleko eziphezulu ngeyunithi ngayinye kunezi-bracket ezivamile kodwa aqeda isidingo sezinto ezihlukene zokubopha. Bala izindleko eziphelele ngesiguli ngasinye kufaka phakathi zonke izesekeli ukuze uhlole ngokunembile ukonga.
Ukuhlaziywa Kokusebenza Kahle Kwezindleko: Amabhuleki Azibophayo vs. Izinhlelo Ezivamile
Izindleko zokuqala zama-bracket zezinhlelo ezizibophayo zivame ukuba phezulu ngo-20-40% kunezama-bracket ajwayelekile amabili. Kodwa-ke, ukuhlaziywa kwezindleko eziphelele kwembula isithombe esicacile.
Ukonga izindleko okuqondile kufaka phakathi:ukususwa kwama-ligatures anwebekayo ($3–$8 ngesiguli ngasinye ngokuvakashelwa ngakunye), isikhathi esincishisiwe senqubo esiholela ekusetshenzisweni okuphezulu kwesiguli, kanye nezinto ezimbalwa ezigciniwe zemishini.
Izinzuzo ezingaqondile zifaka:ulwazi oluthuthukisiwe lwesiguli (akukho zinguquko ezibuhlungu ze-ligature), ukwehla okungenzeka kokuvakashelwa okuphuthumayo kwe-ligatures ephukile noma elahlekile, kanye nokuthuthukiswa kwezilinganiso zokusebenza kahle.
Ukuhlaziywa kwezindleko kuka-2020 okushicilelwe ku-Ijenali ye-Clinical Orthodonticskubalwe ukuthi imikhuba yokushintshela ezinhlelweni zokuzibopha ibhekane nokwehla kwezindleko zesiguli ngasinye cishe ngo-8-12% lapho kubhekwa ukususwa kwe-ligature nokonga isikhathi kunqubo yokwelashwa evamile yezinyanga ezingu-18.
imibuzo ejwayelekile ukubuzwa
Uyini umehluko omkhulu phakathi kwama-bracket asebenzayo nangasebenzi azimele?
