Chithandizo cha mano chakhala chikupita patsogolo kwambiri ku machitidwe a ma bracket omwe amateteza waya wa arch popanda zomangira zachitsulo kapena elastomeric, zomwe zimasintha makina ndi ntchito ya tsiku ndi tsiku. Ma bracket odzipangira okha nthawi zambiri amalimbikitsidwa kuti achepetse kukangana, kusintha kwa waya mwachangu, komanso kukhala ndi chitonthozo chabwino, koma phindu lawo lenileni lachipatala limadalira momwe zomwe akunenazo zimagwirira ntchito. Nkhaniyi ikufotokoza momwe ma bracket awa amagwirira ntchito, komwe angawongolere kugwira ntchito bwino kapena kuyenda kwa mano, komanso zoletsa zomwe zimakhalabe zofunika pakukonzekera chithandizo, mtengo, ukhondo, komanso zotsatira za nthawi yayitali. Kukambiranaku kumayambitsa kufananiza kothandiza ndi ma bracket achizolowezi kotero kuti zabwino ndi zotsutsana zitha kuweruzidwa m'nkhani yachipatala.

Chifukwa chiyani mabulaketi odziyimitsa okha ndi ofunika mu orthodontics yamakono

Kusintha kwa njira yochizira mano kwapangitsa kuti kusintha kosalekeza kuchoka pa njira yachikhalidwe yolumikizirana mafupa ndi zitsulo kupita ku njira zotsekera zamakina zomangidwa mkati.Mabulaketi Odziyimitsa (SLBs)zikuyimira kusintha kwakukulu kwa biomechanical momwemawaya a arch ali olumikizidwamkati mwa malo olumikizira mano, zomwe zimasintha kayendedwe ka mano. Mwa kuphatikiza khoma lachinayi loyenda—nthawi zambiri chitseko chotsetsereka kapena chotchingira kasupe—machitidwe awa amachotsa kufunikira kwa zinthu zomangira zakunja, zomwe zimakhudza mwachindunji magwiridwe antchito azachipatala komanso momwe ligament ya periodontal imagwirira ntchito.

Kwa katswiri wa mano, kugwiritsa ntchito njira zodzipangira mano sikuti kungosintha zinthu zokha komanso kusintha kwakukulu pa njira zochizira. Kuphatikiza kwa ma SLB kumakhudza nthawi yochita opaleshoni, nthawi yoikidwiratu, komanso kudziwikiratu kwa kayendedwe ka mano koyambirira, zomwe zimafuna kumvetsetsa bwino momwe amagwirira ntchito komanso momwe msika ulili.

Zotsatira pa nthawi ya mpando ndi momwe ntchito ikuyendera

Ubwino wofunikira kwambiri wa mabulaketi odzipangira okha ndi kuchepetsa nthawi yoyezera ya mpando wachipatala. Kafukufuku akuwonetsa nthawi zonse kuti kuchotsa ndi kuyika waya wa archwire mu SLB systems kumapulumutsa pafupifupi mphindi 1.5 mpaka 3 pa arch poyerekeza ndi kulumikiza kwachizolowezi kwa elastomeric, ndipo kwambiri poyerekeza ndi kulumikiza kwachitsulo. Pa nthawi yapakati ya chithandizo cha miyezi 24 yomwe imafuna kusintha kwa waya 12 mpaka 15, izi zikutanthauza kuchepa kwakukulu kwa kusintha kwa mpando komwe kumachitika.

Kuphatikiza apo, njira yogwirira ntchito imachepetsedwa mwa kuchepetsa kuchuluka kwa nthawi zomwe zimafunika kuti munthu alowe m'malo mwa ligature. Chifukwa chakuti ma elastomeric ties amawonongeka ndi mphamvu—kutaya mpaka 50% ya mphamvu yawo yoyamba mkati mwa maola 24 oyamba ndikuwonongeka kwambiri m'kamwa—njira zodziwika bwino nthawi zambiri zimafuna nthawi yokumana masabata 4 mpaka 6 aliwonse. Njira za SLB, makamaka mitundu yosakanikirana ndi waya wa mkuwa-nickel-titanium (CuNiTi), zimalola kuti pakhale nthawi yayitali ya masabata 8 mpaka 12 panthawi yoyambira yolumikizana, zomwe zimapangitsa kuti dokotala azigwira ntchito tsiku ndi tsiku komanso kuwonjezera mphamvu yake yochitira zinthu.

Zochitika zachipatala ndi msika zomwe zikuyambitsa kukhazikitsidwa

Msika wapadziko lonse wa orthodontic bracket wawona kusintha mwachangu kupita ku kudzigwirizanitsa, pomwe gawo la SLB likukula pa Compound Annual Growth Rate (CAGR) pafupifupi 7.5%, lomwe likuyembekezeka kupitirira $1.2 biliyoni padziko lonse lapansi pofika kumapeto kwa zaka khumi. Kukula kumeneku kukuyendetsedwa ndi kufunikira kwachiwiri: madokotala omwe akufuna kuchita bwino ntchito ndi odwala omwe akufuna kukonza kukongola ndi ukhondo.

Kuphatikiza apo, kuphatikiza kwa ma orthodontics a digito ndi makina oyika ma bracket positioning kwathandizira kukhazikitsidwa kwa SLB mwachangu. Njira zambiri zamakono zowunikira mkati mwa pakamwa komanso njira zolumikizirana zosalunjika zimakonzedwa kuti zigwiritsidwe ntchito pamakina odziyimitsa okha, chifukwa kusakhalapo kwa mapiko a elastomeric kumalola ma profiles ang'onoang'ono a bracket ndi kupanga template yolondola kwambiri ya digito. Opanga akuyankha mwa kuyika ndalama zambiri mu kafukufuku ndi chitukuko cha ma SLB okongola a ceramic, zomwe zikukankhira msika kutali ndi ma bracket awiri achikhalidwe.

Kodi ma bracket odzipangira okha ndi otani ndipo amagwira ntchito bwanji

Kumvetsetsa momwe ma bracket odzigwirira ntchito amagwirira ntchito kumafuna kusanthula momwe malo olumikizira ma bracket, makina olumikizira ma bracket, ndi waya wa archwire amagwirira ntchito. Mosiyana ndi ma bracket awiri achikhalidwe omwe amadalira kusintha kwa elastic kwa polyurethane tayi kuti ikhale pa waya, ma SLB amagwiritsa ntchito chotchinga cholimba kapena cholimba pang'ono. Kusiyana kwakukulu kumeneku kumatanthauza kukana kutsetsereka (kukangana) ndi kuchuluka kwa ulamuliro womwe dokotala amakhala nawo pa torque ndi kuzungulira kwakukulu panthawi zosiyanasiyana za chithandizo.

Machitidwe a bracket osagwira ntchito poyerekeza ndi ogwirira ntchito

Makina odzipangira okha amagawidwa m'magulu awiri osiyana a biomechanical: osagwira ntchito ndi ogwira ntchito. Ma SLB osagwira ntchito ali ndi chitseko chokhazikika kapena cholumikizira chomwe chimasintha malo olumikizira kukhala chubu chosavuta. Akatsekedwa, cholumikiziracho sichimakakamiza kwambiri waya wa arch, ngakhale mawaya akuluakulu (monga 0.019 × 0.025-inch mu malo a 0.022-inch) atalumikizidwa. Kapangidwe kameneka kamachepetsa kukangana kwachikhalidwe, nthawi zambiri kumasunga kukana pansi pa magalamu 50 panthawi yoyamba yolinganiza ndi kulinganiza, kulola waya wa arch kutsetsereka momasuka ndikuwonetsa mphamvu zake zapamwamba.

Mosiyana ndi zimenezi, ma SLB ogwira ntchito amagwiritsa ntchito kachidutswa ka kasupe kosinthasintha (kawirikawiri kopangidwa ndi nickel-titanium kapena cobalt-chromium) komwe kamalowa m'malo olowera. Ngakhale kuti kachidutswa kameneka kamakhala kopanda mphamvu ndi mawaya ang'onoang'ono ozungulira, kachidutswaka kamakanikiza mawaya akuluakulu amakona anayi (monga, kupitirira 0.016 × 0.022-inch). Mphamvu yokhazikika imeneyi imawonjezera kukangana—nthawi zambiri kupitirira magalamu 150 a kukana—koma imapereka ulamuliro wapamwamba kwambiri wa magawo atatu, makamaka powonetsa mphamvu ndikumaliza kukonza kozungulira panthawi yomaliza chithandizo.

Mawonekedwe a kapangidwe, makina olowetsa zinthu, ndi zipangizo

Kupanga molondola kwa malo olumikizira ma bracket ndi kulimba kwa clip ndikofunikira kwambiri pakugwira ntchito kwa SLB. Makina ambiri amapezeka mu kukula kwa malo olumikizira a mainchesi 0.018 kapena 0.022, ngakhale kuti malo olumikizira a mainchesi 0.022 amakondedwa kwambiri m'makina osasuntha kuti azitha kusuntha bwino mawaya ang'onoang'ono oyambira. Ma clip okha ayenera kupirira kutopa kwakukulu kwa cyclic; ma clip apamwamba a cobalt-chromium amapangidwa kuti azitha kupirira kusintha kosatha ngakhale atakumana ndi mphamvu zotsegula ndi kutseka zolemera mpaka 1.5 kg pa nthawi ya chithandizo cha miyezi 24.

Kusankha zinthu zofunika pa thupi la bracket kumatanthauzanso kuti zimagwira ntchito bwino kuchipatala.Chitsulo chosapanga dzimbiri cha 17-4 PHPopeza ikadali muyezo wagolide wokhazikika komanso kusinthasintha kochepa kwa malo, kufunikira kwa odwala kwapangitsa kuti pakhale ma SLB a polycrystalline alumina (ceramic). Pofuna kupewa kusweka kwa ceramic panthawi yokonza clip, ma SLB amakono okongola nthawi zambiri amakhala ndi kapangidwe kosakanikirana, kuphatikiza choyikapo chachitsulo kapena chogwirira chachitsulo chapadera chokhala ndi rhodium chomwe chimagwirizana bwino ndi thupi la ceramic pomwe chikusunga mawonekedwe ake.

Kuyerekeza ndi mabulaketi achikhalidwe

Kuti tifotokoze momveka bwino kusiyana kwa biomechanical ndi magwiridwe antchito, tebulo lotsatirali likuyerekeza mabulaketi achikhalidwe ndi machitidwe odziyendetsa okha omwe sachitapo kanthu komanso omwe amagwira ntchito m'magawo ofunikira azachipatala.

Kuyerekeza kumeneku kukuwonetsa kuti palibe dongosolo limodzi lomwe lili labwino kwambiri padziko lonse; m'malo mwake, chisankhocho chimadalira ngati dongosolo la chithandizo limaika patsogolo liwiro lolinganiza koyambirira (kukonda ma SLB osagwira ntchito) kapena kuwongolera kumaliza komaliza (kukonda ma SLB ogwira ntchito kapena machitidwe achizolowezi).

Ubwino ndi zofooka za mabulaketi odziyimitsa okha

Kusintha kwa kudzimanga mano kumadalira kwambiri zotsatira za matenda enaake, koma mabuku ndi zomwe zachitika kuchipatala zikuwonetsa zenizeni. Ngakhale kuti ma SLB amachita bwino kwambiri m'magawo ena a biomechanical, amapereka zofooka zomwe madokotala a mano ayenera kuthana nazo, makamaka pankhani yokhudza malo enieni a mano kumapeto kwa njira yochizira mano.

Ubwino wogwiritsa ntchito bwino komanso ukhondo pokonza zinthu

Ubwino waukulu wa ma SLB uli mu luso lolinganiza bwino, makamaka pakakhala kukhuthirana kwambiri. Mwa kuchepetsa kukana kutsetsereka ndi 60% poyerekeza ndi mabulaketi omangiriridwa ndi elastomeric munthawi youma, ma SLB osagwira ntchito amalola mphamvu zopepuka, zopitilira kufalikira m'mano angapo. Izi zimathandiza kukula kwa arch yopingasa ndi kulumikizana ndi kutayika kochepa kwa ma anchorage. Mwachipatala, izi nthawi zambiri zimapangitsa kuti kukhuthirana koyamba kuthe msanga mkati mwa miyezi 6 mpaka 9 yoyambirira ya chithandizo.

Ukhondo ndi ubwino wina wofunika. Ma elastomeric ligatures amatha kusungunuka kwambiri ndi ma plaque komanso kulowa m'malo mwa mabakiteriya. Kafukufuku wa zachipatala akusonyeza kuti ma elastomeric ties amasunga pafupifupi 38% ya plaque biofilm kuposa malo osalala achitsulo a SLB clips. Mwa kuchotsa ma polyurethane ties okhala ndi porous, machitidwe odzigwirizanitsa okha amachepetsa katundu wa tizilombo toyambitsa matenda kuzungulira maziko a bracket, motero amachepetsa chiopsezo cha zilonda zoyera (enamel demineralization) ndi gingival hypertrophy panthawi ya chithandizo cha nthawi yayitali.

Malire pakuwongolera kuzungulira ndi kumaliza

Ngakhale kuti amagwira ntchito bwino poyesa ma level oyambirira, ma SLB osasunthika nthawi zambiri amavutika ndi rotational control ndi torque expression panthawi yomaliza. Chifukwa chitseko cholimba sichimakanikiza waya wa archwire pansi pa slot, pali "play" yokhazikika pakati pa waya ndi bracket. Mwachitsanzo, waya wa rectangular wa 0.019 × 0.025-inch mu 0.022-inch passive slot umasonyeza torque play ya madigiri pafupifupi 10.5. Ngati dokotala akufuna torque expression yayikulu kuti achotse incisor retract, play iyi imafuna kugwiritsa ntchito ma springs othandizira torque kapena kupita patsogolo msanga kwa mawaya akuluakulu, zomwe zingakhale zovuta kuchipatala.

Ma SLB Ogwira Ntchito amachepetsa kutayika kwa torque kumeneku kudzera mu kagawo ka masika, koma amabweretsa zofooka zawo. Ma clip ogwira ntchito amatha kutopa ndi makina; mkati mwa miyezi 18 mpaka 24 yochizira, kupsinjika kosalekeza kumatha kuchepetsa mphamvu ya kagawo ndi 15% mpaka 20%, zomwe zimapangitsa kuti kuwongolera komaliza kukhale kovuta. Kuphatikiza apo, kuchuluka kwa ma calculus kapena zinyalala za zakudya nthawi zina zimatha kusokoneza njira zovuta zotsetsereka za machitidwe osagwira ntchito komanso ogwira ntchito, zomwe zimafuna njira zochepetsera nthawi kuti zitsegule kagawo kake kapena, pazochitika zoopsa, zimafuna kusintha ma bracket.
