Amabhuleki ensimbi azenzela wona: Ukukhetha okusha kokwelashwa okuphumelelayo kwe-orthodontic

1. Incazelo Yobuchwepheshe kanye Nokuvela Kwemvelo
Ama-bracket ensimbi azibophayo amelela intuthuko ebalulekile kubuchwepheshe be-orthodontic obungaguquki, kanti isici sawo esiyinhloko ukufaka esikhundleni izindlela zendabuko zokubopha nge-internal sliding mechanism. Kusukela ngawo-1990, lobu buchwepheshe bukhule eminyakeni engaphezu kwamashumi amathathu yentuthuko. Ngokusho kwedatha yemakethe yomhlaba wonke kusukela ngo-2023, ukusetshenziswa kwama-bracket azibophayo kuma-orthodontics angaguquki kufinyelele ku-42%, kanti izinga lokukhula lonyaka lihlala lingaphezu kuka-15%.

2. Izici Zobuchwepheshe Eziyinhloko

Ukusungula izinto ezintsha kwesakhiwo
Umklamo wesembozo esishelelayo (ukujiya okungu-0.3-0.5mm)
Uhlelo lomhlahlandlela oqondile (i-coefficient yokungqubuzana ≤ 0.15)
Isakhiwo se-hook yokudonsa esihlanganisiwe

Uhlelo lwemishini
Uhlelo lwamandla okukhanya oluqhubekayo (50-150g)
Ukulawula ukungqubuzana okunamandla
Ukubonakaliswa kwe-torque okunezinhlangothi ezintathu

ipharamitha yokusebenza
Inani lamandla okuvula nokuvala: 0.8-1.2N
Impilo yesevisi ≥ iminyaka emi-5
Ukunemba kwesikhala ± 0.01mm

3. Ukuhlaziywa Kwezinzuzo Zemitholampilo
Ukuthuthukiswa kokusebenza kahle kokwelashwa
Isikhathi sokwelashwa esimaphakathi sifinyezwa ngezinyanga ezingu-4-8
Isikhathi esiphakathi kokuvakasha kokulandelela sinwetshiwe saba amasonto angu-8-10
Isikhathi sokusebenza eceleni kwesihlalo sincishiswe ngo-40%

Ukulungiswa kwe-biomechanical
Ukungqubuzana kuncishiswe ngo-60-70%
Okuningi kuhambisana nokunyakaza komzimba
Izinga lokumuncwa kwempande yezinyo lehle ngo-35%

Ukuthuthukiswa kolwazi lwesiguli
Isikhathi sokuqala sokuzivumelanisa nezimo ≤ izinsuku ezi-3
Ukucasuka kwamafinyila kuncishiswe ngo-80%
Ubunzima bokuhlanza umlomo buyancipha

4. Iziqondiso Zokukhetha Emitholampilo
Iziphakamiso zokuzivumelanisa nezimo
Ukwanda okusheshayo kwe-palatal entsheni: Isincomo sezinhlelo ezingasebenzi
Ukulungiswa okuhle kwabantu abadala: khetha imikhiqizo esebenzayo
Ukwelashwa kokukhubazeka kwamathambo: Cabanga ngomklamo ohlanganisiwe

Uhlelo lokuhambisana lwe-Archwire
Isigaba sokuqala: Intambo ye-nickel-titanium esebenza ngokushisa engu-0.014″
Isigaba esiphakathi: 0.018×0.025″ ucingo lwensimbi engagqwali
Isigaba sakamuva: 0.019×0.025″ intambo ye-TMA

Amaphuzu abalulekile okuphathwa kokulandelela
Hlola isimo sendlela yokukhiya
Hlola ukumelana kokushelela kwe-archwire
Qapha indlela yokunyakaza kwamazinyo

Ngokusebenzisa ubuchwepheshe obuqhubekayo, amabhuleki ensimbi azibophayo aguqula indlela ejwayelekile yokwelashwa kwe-orthodontic okuhleliwe. Ukuhlanganiswa kwawo kokusebenza kahle kanye nenduduzo kuwenza abe ukukhetha okubalulekile ekwelashweni kwe-orthodontic kwanamuhla. Ngokuhlanganiswa okujulile kobuchwepheshe obuhlakaniphile nobedijithali, lobu buchwepheshe buzoqhubeka nokuhola ukusungulwa kwamamodeli okwelashwa kwe-orthodontic.
