Ii-Elastics ezinemibala ziphucula njani ukuthobela imithetho kwizigulane ze-Teen Orthodontic?

Intshayelelo

Unyango lwe-orthodontic lolutsha luxhomekeke kakhulu kwindlela yokuziphatha kunye noomatshini, kwaye ukuguguleka kwe-elastic yemihla ngemihla kudla ngokuba apho izicwangciso ziphela khona. Esinye isikhuthazo esisebenzayo ngokumangalisayo kukukhetha umbala: ukunika ulutsha ukhetho lwee-elastics ezinemibala kunokwenza unyango luvakale luyimfihlo ngakumbi, lubonakala, kwaye kulula ukuzibophelela kulo. Eli nqaku lichaza indlela olo khetho luncinci loyilo oluxhasa ngayo ukuthobela umthetho, isizathu sokuba luhambelana nengqondo yolutsha, kunye nokuba lunokuthetha ntoni ekusebenzeni kakuhle konyango, iziphumo zokuqeshwa, kunye nokwaneliseka kwesigulana. Ikwabeka izinto ezisebenzayo ekufuneka oogqirha kunye nabazali baziqwalasele xa besebenzisa ii-elastics ezinemibala ukukhuthaza intsebenziswano eqhubekayo.

Indlela i-Elastics enemibala enokuyiphucula ngayo i-Teen Orthodontic Compliance

Ukuthobela imithetho yolutsha kuseyeyona nto ingaqhelekanga kunyango lwamazinyo. Nangona uphuhliso lwe-biomechanical luye lwaphucula uyilo lwezibiyeli kwayeii-alloys ze-archwire, iziphumo zonyango zisaxhomekeke kakhulu kwintsebenziswano yezigulana, ingakumbi malunga nococeko lomlomo kunyeukuguguleka okuqhubekayo kwe-interarch elastikiAmanani okungathobeli imithetho kwizigulane eziselula ezinesifo samathambo adla ngokuqala kwi-30% ukuya kwi-50%, into ebangela ukuba umntu angakwazi ukujongana nonyango aze anciphise iziphumo zokugqibela ze-occlusal.

Ukunciphisa oku, oogqirha basebenzisa ngakumbi iindlela zokuziphatha ukukhuthaza ubunini besigulana kwinkqubo yonyango. Ukuhlanganiswa kwee-ligatures ezinemibala kunye ne-interarch elastics kusebenza njengesixhobo sengqondo esingabizi kakhulu nesinempembelelo ephezulu. Ngokuguqula inkqubo yezonyango engasebenziyo ibe ngamava asebenzisanayo, iindlela zokulungisa amazinyo zinokusebenzisa isayikholoji yolutsha ukuphucula ukunamathela kwiindlela zokunxiba ezimiselweyo.

Kutheni ukukhetha okubonakalayo kubalulekile kwinkuthazo yolutsha

Ubutsha linqanaba lokukhula elibonakaliswa ngumnqweno onamandla wokuzimela kunye nokuziveza. Unyango lwe-orthodontic, oludla ngokumiselwa ngabazali kwaye lwenziwa ngoogqirha, ngokwendalo luyayithintela le ndlela yokuzimela. Ukuvumela ulutsha ukuba lukhethe imibala yee-elastomeric ligatures zabo (ii-O-rings) okanye ii-interarch elastics kubuyisela ulawulo oluthile. Izifundo zokuziphatha zeklinikhi zibonisa ukuba ukubonelela ngokhetho oluncinci nolulawulwayo kwindawo yokhathalelo lwempilo kunokunyusa amanqaku okubandakanyeka kwesigulana ukuya kuthi ga kwi-40%.

Olu khetho olubonakalayo luguqula isixhobo sokulungisa amazinyo ukusuka kwisixhobo sezonyango kuphela sibe sisixhobo esinokwenziwa ngokwezifiso. Izigulana zihlala zilungelelanisa imibala yazo neeholide, imibala yesikolo, okanye izinto ezithandwa bubuhle bazo. Olu nxulumano oluhle lunciphisa ihlazo kunye nokukhungatheka okuqhele ukunxulunyaniswa nezixhobo ezisisigxina, nto leyo ekhuthaza ingqondo yesigulane yokusebenzisana ngakumbi ngexesha lokulungiswa kwesitulo kunye nokhathalelo lwasekhaya.

Indlela ukuthobela imithetho okuchaphazela ngayo ukusebenza kakuhle konyango

Ukusebenza kakuhle koomatshini bonyango lwe-orthodontic kuxhomekeke ngqo ekusebenziseni amandla rhoqo. Kwi-interarch elastiki, oogqirha badla ngokunika iiyure ezingama-20 ukuya kwezingama-22 zokunxitywa kwemihla ngemihla ukuze kufezekiswe intshukumo efanelekileyo yamazinyo. Xa inkuthazo incipha kwaye isigulana sinciphisa ixesha lokunxitywa ukuya kwiiyure ezili-12 okanye ngaphantsi, amandla e-biomechanical aba ngaxeshanye, nto leyo ekhokelela kwizigaba zokuphumla kweeseli kwi-periodontal ligament endaweni yokulungiswa kwamathambo okusebenzayo.

Oku kungathobeli imithetho kuthetha ngokuthe ngqo ukungasebenzi kakuhle kwezonyango. Ubude bonyango bunokunyuka ngokulula ngeenyanga ezi-3 ukuya kwezi-6 ngenxa yokuguga okungaguqukiyo kwe-elastic, okufuna idinga elongezelelweyo kunye nokunyuka kweendleko zokuqhuba umsebenzi. Ngokusebenzisa i-elastics enemibala ukugcina amanqanaba aphezulu enkuthazo yesigulana, oogqirha banokuqinisekisa ukuba impendulo yebhayoloji kumandla asetyenzisiweyo ihlala ingaphazanyiswa, ngaloo ndlela begcina ishedyuli yonyango isendleleni.

Izinto Ezibangela Ukusetyenziswa Kwe-Elastic Enemibala Eqaqambileyo

Ukusetyenziswa kwe-elastomeric enemibala kufuna ukuqonda zombini isayensi yezinto ezilawula iimveliso ze-polyurethane kunye neendlela zokuziphatha zabantu abaselula. Iimveliso ze-elastomeric zifumaneka kakhulu kwi-orthodontics, kodwa iimpawu zazo zoomatshini aziguquki. Ukuwohloka kwamandla kwe-elastomeric ligatures kunye neetsheyini kudla ngokufikelela kwi-50% ukuya kwi-70% kwiiyure zokuqala ezingama-24 zokuvezwa emlonyeni.

Ngenxa yokuba ezi zinto zifuna ukutshintshwa rhoqo—ngokuqhelekileyo rhoqo emva kweeveki ezi-4 ukuya kwezi-6 ukuze zisetyenziswe ii-ligatures kwaye yonke imihla zisetyenziswe ii-interarch elastics—imfuneko ephindaphindiweyo ye-elastomerics ezintsha idala umjikelo oqhubekayo wokubandakanyeka kwesigulana. Ukuqonda umahluko phakathi kwezi mveliso kunye neendlela zokuziphatha eziqhuba ukusetyenziswa kwazo kubalulekile ekuphuculeni ukusebenza kakuhle kwe-biomechanical kunye nokuthobela imiqathango yesigulana.

Indlela ii-elastics ezinemibala eyahluke ngayo kwii-ligatures kunye nee-interarch elastics

Nangona izigulana zihlala zisebenzisa igama elithi “iirabha” ngokutshintshana, oogqirha kufuneka bahlule phakathi kwe-elastomeric ligatures kunye ne-interarch elastics xa beyila icebo lokuthobela imithetho. Ii-Elastomeric ligatures (okanye ii-O-rings) zisetyenziswa ngugqirha ukuze aqinise i-archwire ngaphakathi kwendawo yebracket. Ukukhetha imibala yazo kunika ukuphuculwa kobuhle kwaye kwakha umdla wokudibana, kodwa azidingi ukungenelela kwemihla ngemihla kwesigulana.

Ngokwahlukileyo koko, ii-interarch elastics zii-bands ezisuswayo ezisetyenziselwa ukulungisa i-malocclusions ezifana nokungafani kweClass II okanye iClass III. Ezi zifuna ukuthotyelwa ngokungqongqo kwesigulane, njengoko isigulane kufuneka sizisuse xa sisitya kwaye sizitshintshe izihlandlo ezininzi ngemini ngee-bands ezintsha ukuze kugcinwe amanqanaba afanelekileyo amandla (ngesiqhelo ukusuka kwi-2.5 ukuya kwi-6.0 ounces). Ukubonelela ngee-interarch elastics ezinemibala kusebenza njengesikhumbuzo esibonakalayo rhoqo kwisigulane sokugcina ishedyuli yaso yokunxiba yemihla ngemihla.
