Kulo lonke ujikelezo lobomi lwamazinyo omntu kabini luguquka rhoqo. Ukutshintshwa kwamazinyo okuqala kuthiwa ngamathambo okanye amazinyo omntwana. Iingcali zamazinyo, igama liqhelekileyo njengezinyathelo eziprayimari, ezinokwenziwa okanye ezingenakunyakaziswa. Emva kokulahlekelwa kwamazinyo ebisi, kwindawo yabo ekugqibeleni zikhula zendabuko. Nangona kunjalo, ngamanye amaxesha abazali banokujamelana neengxaki ezifana nokulahleka kwintsana yamazinyane.
Isikhathi samazinyo angasigxina
Umhlathi osezantsi: i-incisors ephakathi - ekuqaleni kwesahlulo sesibini sonyaka, i-lateral - iinyanga ezi-7, yesine kunyaka okanye unyaka kunye neenyanga ezine, iifang ukuya kwiinyanga ezingama-20, amazinyo amahlanu ngonyaka kunye neenyanga ezisibhozo kunye neyesibini ukuya kwisiqingatha. Umhlathi ophezulu: ii-incisors eziphakathi kweenyanga ezi-7,5, ezixhaswa kwiinyanga ezili-8, amazinyo amane ngonyaka kwaye zifike kwiinyanga ezili-16, iifowuni zonyaka kunye neyesine kunye neenyanga ezisibhozo, iinyanga ezintlanu ukuya kwezi-30.
Isizathu samazinyo angasigxina obisi
Ukulahlekelwa kwamazinyo ebisi kuqala ngokuqala kokukhula kwamazinyo asisigxina. Inkqubo yokulahlekelwa kwamazinyo eziphambili kubangelwa ukuhlaziywa kweengcambu zobisi, oko kukuthi, ingcambu iyacinywa kancane.
Ngokuhluma kwezinyo ezinqamlezayo ezidlula emlanjeni ngokuthe ngqo kumathishini athambileyo emhlanjeni, ingcambu yezinyo eziphambili ezincinci ziba ncinane kwaye zincinci. Kwaye ngenxa yoko, ingcambu yezinyo zobisi ayikwazi ukuyibeka kwisigodlo ayisayi kuhlala kwaye izinyo ngokuzikhethela zahlula kwindawo yayo.
Impembelelo yokulahleka kwangaphambili kwamazinyo ekukhuleni kwamazinyo asisigxina
Enye yemisebenzi ebalulekileyo yamazinyo obisi yiindawo zokutshintshwa kweyesibini, okunye amazinyo asisigxina. Kwimeko apho umntwana, njengoko ekhula ngaphambi kwexesha, ahlahla izinyo zobisi aze angagcini indawo yayo, ngoko kwixesha elizayo amazinyo angapheliyo angena endaweni yawo angaphoswa okanye ukukhula kwabo kunzima.
Ukulahlekelwa kwangaphambili kwamazinyo kunokubangela ukuba amazinyo asisigxina ahlume. Khawucinge ngomzekelo wokuwa kwexesha elide ngaphambi kweyesibini yomlenze womntwana womntwana.
Ngokukhula okuqhelekileyo kwamazinyo, okokuthi, utshintsho oluqhelekileyo lwamazinyo angasigxina kumazinyo asisigxina, kufuneka kube nokuhlaziywa kweengcambu zamazinyo eziphambili. I-root resorption ikhulula indawo kwizinyo ezizenzekileyo ezilandelayo kwaye ibonisa indawo efanelekileyo kwindawo yayo kwindawo yokutyunjwa. Ukongeza, ukuba i-molar yesibini eyimfuneko yayisetyenziswa ngaphambi kokuphela kwesiphene, ukufumana oko kwinqanaba kukunceda ukuqinisekiswa kwendawo enokusisigxina nokuchanekileyo.
Kodwa ukuba i-milk molar iswelekile kwangaphambili kwisigaba sokuqala sokutshintsha kwamazinyo, umsebenzi wayo wokubonisa indawo kwindawo engunaphakade ayibonakali. Ngenxa yoko, inzondo yokugqibela ye-molar izakufuna indawo entsha efanelekileyo kwaye iqalise ukuhamba kwiphakathi lesithuba samahhala. Ngenxa yoko, inyosi encinci ye-molar inokuhlala ingenawo indawo yayo okanye kuya kuba nzima ukukhupha inyosi encinci, kuba ikwazi ukugqithisa i-tum.
Ukutshintshwa kwendawo yokubonisa, uye waphuma ngaphambi komhla wokugqibela wezinyo, sebenzisa idivayisi ekhethekileyo.
Ukuba akunakwenzeka ukuphepha ukukhutshwa kwezinyo zobisi kwinqanaba lokuqala lophuhliso olusisigxina kwaye kuyimfuneko ukugcina indawo yezinyo ezizenzekileyo ezizayo, oogqirha bamazinyo basebenzisa isixhobo - umnini wesayithi lezinyo ezikhutshiwe. Le fowuni iqhotyoshelwe kwenye yamazinyo ecaleni apho inyosi isuswe khona, kwaye ukusuka ekupheleni kwesibili idivaysi ibanjwe ngetambo kwizinyo ezivela kwicala elingaphandle kwendawo engenanto. Ngoncedo lendlela (ukugcina indawo yesikhokelo sezinyo ezisuswe kwangaphambili), kusekho indawo yokukhula kwezinyo ezinqamlekileyo kunye namazinyo asondeleyo akuyi kuhamba, ukuhlala kwindawo yomnye umntu. Inceda ukubonakala kakuhle kwamazinyo asisigxina kunye nomsebenzi owenzelwe zona. Isixhobo esinjalo siya kunceda ukuphepha ukungenelela kwangakumbi ekulungiseni amazinyo, njengama-braces. Lo mnikazi ususwe ngokukhawuleza xa ukugqitywa kwezinyo ezitshatyalaliswayo ngegum kubonakala.
