Eli nqaku lichaza izizathu eziphambili zokungaphumeleli kwebhondi, amazinga okulinganisa abonisa ingxaki, kunye namanyathelo asebenzayo aphucula ukugcinwa kwebhondi kwimisebenzi yemihla ngemihla. Ekugqibeleni, abafundi baya kuba nesakhelo esicacileyo sokunciphisa ukungaphumeleli, ukukhusela ukusebenza kakuhle konyango, kunye nokuphucula iziphumo zesigulana.
Yintoni Ukusilela Kwebhondi Yesibhakela kwaye Kutheni Kubalulekile?
Ukunamathela okuthembekileyo kwebracket sisiseko sokusebenza kakuhle nempumelelo yonyango lwanamhlanje lwe-orthodontic. Xa ibracket isuka kumphezulu wezinyo ngaphambi kwexesha, iphazamisa amandla e-biomechanical afunekayo ekushukumeni kwezinyo, nto leyo ekhokelela kwiziphumo zonyango ezibuthathaka kunye nexesha elandisiweyo lonyango.
Kwindawo yeklinikhi elawulwa kakuhle, umlinganiselo owamkelekileyo jikelele wamazinga okusilela kwebhondi yebracket uhlala uphakathi kwe-5% kunye ne-10%. Ukudlula lo mkhawulo kubonisa isiphene esicwangcisiweyo ekukhetheni izinto, ubuchule beklinikhi, okanye ulawulo lokuthobela izigulane. Ukuqonda indlela ekwenziwa ngayo oku kusilela linyathelo lokuqala lokuphumeza imigaqo yokulungisa.
Kutheni ukungaphumeleli kwebhondi yebracket kwandisa ixesha lesitulo
Isiphumo esikhawulezileyo sokungaphumeleli kwebhondi yesibiyeli kukwanda okukhulu kwexesha lesitulo elingacwangciswanga. Ukutshintsha isibiyeli esinye kufuna ukususa intsalela ye-composite, ukuphinda uyipume, uyihlukanise, uyikhuphe, uyibeke kwindawo yayo, kwaye uyibeke kwakhona isibiyeli esitsha. Olu landelelwano ludla ngokuthatha imizuzu eli-10 ukuya kweli-15 yexesha leklinikhi.
Ngaphaya kokuphazamiseka kwentlanganiso kwangoko, ukusilela kwebhondi okungalungiswanga kungena kwixesha elide lonyango. Izifundo zeklinikhi zibonisa ukuba ukungaphumeleli kwebhreyithi nganye kunokwandisa ixesha lonyango lwesigulana ngenyanga e-1 ukuya kwezi-2.

Indlela yokuchaza ngokucacileyo ukungaphumeleli kwebhondi yebracket
Ukusilela kwebhondi yebracket kuchazwa ngobuchwephesha njengokususwa okungafunekiyo kwebracket ye-orthodontic ukusuka kumphezulu we-enamel ngaphambi kwesigaba sonyango esicwangcisiweyo sokuqhawula ibhondi. Ukuze kufunyaniswe unobangela oyintloko, oogqirha kufuneka bahlele ukusilela ngokusekelwe kwi-Adhesive Remnant Index (ARI), echaza apho kwenzeke khona ukwaphuka.
Ukungaphumeleli kunokwenzeka kwi-enamel-adhesive interface (okubonisa ukugrumba okubi okanye ukungcola komswakama), ngaphakathi kwe-adhesive ngokwayo (ukungaphumeleli kokubambisana, okubonisa ukunganyangeki okungaphelelanga okanye izinto eziphelelwe lixesha), okanye kwi-bracket-adhesive interface (okubonisa ukungena ngokwaneleyo kwe-mesh okanye ukungcola kwesiseko). Ukuze isebenze kakuhle, amandla e-shear bond (SBS) kufuneka awele kwifestile ethile yonyango: 6 ukuya kwi-8 Megapascals (MPa) ngokubanzi iyadingeka ukumelana namandla okuhlafuna kunye ne-orthodontic, ngelixa ukudlula i-14 MPa kwandisa kakhulu umngcipheko wokuqhekeka kwe-enamel ngexesha lokuqhekeka okucwangcisiweyo.
Yintoni ebangela ukungaphumeleli kwe-Bracket Bond ngexesha loNyango lwe-Orthodontic
Ukuhlukana kwezibiyeli akusoloko kubangelwa yimpazamo enye; ngokuqhelekileyo yingxaki yezizathu ezininzi ebandakanya ukwenziwa kweklinikhi, isayensi yezinto eziphathekayo, kunye nezinto eziguquguqukayo zesigulana. Ukuchonga unobangela othile kufuna uphononongo olucwangcisiweyo lwemeko-bume yokubopha kunye namandla endalo asetyenziswa kwisibiyeli.
Ngokwahlula izinto eziguquguqukayo ezifana nolawulo lomswakama, i-adhesive mechanics, kunye nokuphazamiseka kwe-occlusal, iingcali zinokuchonga ngqo apho i-protocol yabo yokubopha idilika khona.
Indlela imeko ye-enamel kunye nokufuma okuchaphazela ngayo amandla ebhondi
Imeko ye-enamel kunye nokuba khona komswakama zezona zinto zibalulekileyo ezibangela ukuba i-bond ihlale ixesha elide. Ukungcola kwe-saliva, igazi, okanye ulwelo oluqhekekileyo ngexesha lenkqubo yokubopha yeyona nto iphambili ebangela ukungaphumeleli, ekwaziyo ukunciphisa amandla e-shear bond ngama-30% ukuya kuma-50%. Nokuba ngumswakama ojikeleze i-air conditioner ovela ekuphefumleni komguli kunokuphazamisa ukugcinwa kwe-micro-mechanical okudalwe yi-etchant.
Ukulungiswa kwe-enamel nako kuthetha impumelelo. Inkqubo eqhelekileyo ifuna imizuzwana eli-15 ukuya kwengama-30 yokugrumba nge-37% ye-phosphoric acid ukwenza i-microporosity eyaneleyo. Nangona kunjalo, iimeko ze-enamel ezingaqhelekanga, ezifana ne-fluorosis, i-hypomineralization, okanye ubukho bamazinyo aqukuqelayo, ziqulathe iileya ze-enamel ezitshintshileyo ezimelana nokugrumba okuqhelekileyo, nto leyo edinga amaxesha okwandiswa kokugrumba okanye i-microabrasion ukuze kufezekiswe amandla ebhondi ye-6 MPa yokuqala.
