Iinkozo ze-Canine zibalulekile ukutya nokuthetha
Ama-cuspids aphakathi kwamazinyo aphezulu kakhulu emlonyeni ngenxa yobume bawo obude kunye nobude obude. Kwakhona kuthiwa ngamazinyo e-canine (okanye "amazinyo" okanye "amazinyo eso" xa ebhekisela kumazinyo aphezulu), i-cuspids iphakathi kwama- incisors (amazinyo amancinci angaphambili emlonyeni) kunye namazinyo angaphambili.
Indima yeCuspids
Umntu uya kubakho ezine i-cuspids: ezimbini eziphezulu (ezaziwa njenge-maxillary cuspids) kunye nezimbini ezisezantsi (ezaziwa njenge-mandibular cuspids).
Isetyenziselwa ukutya nokuqhawula ukutya, i-cuspids inkulu kwaye iyomelele kunokuba i-incisors neengcambu ezichukumisa ngokujulile emathanjeni omhlathi.
I-Cuspids yinto yokugqibela yezinyo zangaphambili ukuqhuma, ngokuqhelekileyo phakathi kweminyaka eyi-11 no-13. Ubude bayo budibene kunye neengqumbo zabo ezingatshatanga, eziphambili ziphambili ekulungiseni ukuluma. Nayiphi na impazamo okanye ukungalungiswanga kungaphazamisa ukutya nokuthetha.
Kukho iingxaki ezibini eziqhelekileyo ezinxulumene nama-cuspids:
Cuspids echaphazelekayo
Inyosi echaphazelekayo yinto "eyanamathela" kwaye ihluleka ukukhupha kwisithuba sayo esifanelekileyo. I-cuspids yama-maxillary yimiba yesibini eqhelekileyo, ecaleni kwamazinyo ehlakaniphile , ukuba ifuthe. Ukuba oko kwenzeka, lezinyo ziqala ukukhupha okanye ziphakame kakhulu phambi kwamanye amazinyo (kwindawo ebizwa ngokuba yi-vestibular position) okanye emva kwamanye amazinyo kwicala lomlenze (kwindawo yokulala).
Unyango lunokubandakanya ukusetyenziswa kweebhonki ukuvula izikhala kwaye uvumele ukuqhuma okufanelekileyo.
Kwezinye iimeko, ukuhlinzwa ngomlomo kunokufuneka ukuba ususe nayiphi na amazinyo aphazamisayo.
Ukuba kwenziwa xa i-cuspids iqala ukuvela, kukho onke amathuba ukuba amazinyo aya kulungelelanisa. Ukuba ishiywe ingaphatyathwa kuze kube yilapho ikhulile, inyoyi echaphazelekayo ingagqiba ukufakwa kwisithuba kwaye idinga ukukhutshwa.
Ibhuloho yamazinyo okanye ukuveliswa kuya kufuneka ukuba kuzaliswe isithuba.
Gingival Recession
I-Gingival recession, eyaziwayo njengezinsini eziphelileyo, inokwenzeka ngeenxa zonke nayiphi na izinyo kodwa ixhaphaza ama-cuspids maxillary kunye ne-mandibular incisors. Le meko ixhomekeke kwiinyopho ezinobuthi, ukutshaya, ukucoceka kwamazinyo, kunye nesifo sexesha .
Umqathango unokubangela, ngokukodwa, ngamanxiwa avela ngokungafanelekanga. Ukuba amazinyo aphikisiwe, iinjongo zingatyulwa kwiindlela ezichaseneyo, kubangele ukucuthwa kwezicubu kunye nokunyuka kwingozi kwingozi. Ngaphezu koko, ukuchithwa kakubi kwamacuspids kunokukwenza ukuxubha kunzima kwaye kuholele ekwakheni i-tartar kunye nokuphuhliswa kwesifo segum.
Ukuze ulungise umonakalo, oogqirha be-orthodontic bangatyelela kwi-grafting ye-tissue ephathekayo apho iisuncu zithatyathwa ukusuka kwelinye inxalenye yomlomo wakho okanye umniki-mhlaba kwaye uqhutywe endaweni endaweni ye-tissue loss. Kwiimeko zesifo segum esiphezulu, inqubo ebizwa ngokuba yincinci yokunciphisa i-pocket ingasetyenziselwa ukususa izicubu ezigulayo kwaye zivumele ukuba i-brushing ne- flossing ibe lula ukukhusela ukubola.
