Vaverengwa mazino ari dentistry

Chete pakutanga kuaona sokuti meno yevanhu mumwe. Kutaura zvazviri, mumwe nomumwe mazino ane mumwe configuration, iyo yakaumbwa pamusoro nezviuru zvemakore, uye izvo Zvakanakisa unoenderana aurayiwe zvimwe mabasa. Rinotsanangura yakasiyana maumbirwo mazino hwevanhu yavo chinangwa: Vamwe mazino isu kuruma kure zvokudya (incisors uye canines), vamwe isu dzinodzeya nayo (kutsenga mazino). Uye meno zvinoodza kurwara, uye kana tinosvika wemazino, zvadaro refu uye dzinovhiringidza vanotsanangura kuti nezino zvinoda kurapwa, chiremba wemazino awana "varwere" kupfurikidza tapping girazi yose mazino mumutsetse: iyo zino murwere rakapa kuchema, uye zvakarurama.

Zvisinei, mumwe chiremba mazino anogona kuderedza kutambura zvakananga anodana dzava zino. Pashure pezvose, zvirokwazvo iwe wakanzwa mumwe vanachiremba vemazino vanonzi "nhanhatu", "masere", etc. zvimwe mazino rinosvika wokurera ari mazino mushonga. Countdown wavo rinomhanya kubva pakati zino mutsara kuruboshwe uye kurudyi. Somuenzaniso, ivo dzinonzi rokutanga uye rechipiri mberi, kana mazino pamberi riri zvose shaya. Maumbirwe wavo sandara, mbezo, vachibvumira kuruma kubva guru chimedu duku zvidimbu zvokudya pasina matambudziko. Nechikonzero ichochi uye meno cône serin'i - the "veTroika". Uchibatsirwa wavo, unogona munovhiya uye kunyange kuruma kure zvikuru batana zvidimbu.

Mashandiro mazino yasara - kutsenga zvokudya, kureva nokuikuya kumamiriro akanakira kwomuzvarirwo zvomudumbu muitiro. Sezvo neimwe zino ane chairo basa, uye rinowanikwa kwavo chikamu mutoro, saka kana kubvisa mutoro akanga akatakura, akatora meno yasara. Izvi zvingaita kuti deformation yavo. Kuti izvi zvisaitike, unofanira nekukurumidza yokutsiva zvikaramba zino prosthesis.

Asi shure kune nyaya. Vakaverengwa kwevanhu mazino unobuda sezvinotevera: "quartet" uye "shanu" anoreva dög mazino diki kana premolars. Large dög mazino, kana molars - a "nhanhatu", "Zvinomwe" uye "masere". Wechitanhatu meno worudzii Anodzivisawo panguva kuvhara shaya kuzorora imwe. Pemvura posterior mazino haisi mvere, pamusoro payo pane anorovera, miganhu. In premolars pamusoro tubercles maviri, ukuwo molars - 4-5. Kuvapo miganhu izvi kunobatsira maximize kubudirira kutsenga zvokudya.

Zvisinei, vaisvika meno ari dentistry kunosanganisira uyewo weboka kupinda zvikamu zviri dentition. All zvina, saka usashamisike kana pakarepo kuwana kuti une hosha zino haisi rechitanhatu mana nematanhatu, pasinei chokuti, hunonzi, vane 32. Sezvataurwa pamusoro apa, chiverengero mazino yakatanga kusvika pakati , diverging kwakasiyana-siyana. Mumwe nomumwe mativi aya ndiwo chidimbu uye musoro kurudyi - ndiye "gumi", yokumusoro kuruboshwe - vari "makumi" yakaderera kuruboshwe - "matatu" uye nechepazasi zvakanaka - "sorokovke". Naizvozvo, Somuenzaniso, mazino rokumusoro rworudyi rokutanga uye rechipiri, chokwadi, muri 11 M uye 12 m, uye rechishanu nerechitanhatu kuderedza kuruboshwe - 35 uye 36.

Vaya vane "dambudziko" mazino uchenjeri, ungangove uchiziva kuti "Group masere", asi vanhuwo vakaverengwa mazino chinoratidza kuti nhamba yavo chaihwo anogamuchira zvichienderana umo chidimbu nayo kumera. Nemamwe mashoko, mazino uchenjeri vakaverengwa 18, 28, 38 uye 48 A "mbiri", "vatatu", nezvimwewo, vanonzi mazino, kwete zvivanakire. Saka kutaura, "mazita diminutive".

Uye pano pane meno avana rinosvika steeper zvikuru kupfuura nedzevakuru. Chokwadi chokuti midzi Deciduous mazino wakaiswa paupamhi kunze, achivabvumira kufukidza utachiona kwemeno zvechigarire ramangwana. Kana x-mwaranzi, kutanga ava kuoneka. Sezvo zvachose mazino inoverengwa kubva "dzakawanda" kuti "sorokovok 'mukaka kuonekwa sezvinotevera: pamusoro kodzero - a" mashanu ", yokumusoro kuruboshwe -" shestidesyatki ", rezasi kuruboshwe -" semidesyatki ", nechepazasi zvakanaka -" vosmidesyatki ". Zvakakosha kuyeuka kuti kana mwana akakutsamwisa meno mukaka, vanofanira zvachose kubatwa, pasinei vari ipapo vachiri kuwa, nokuti zvose zvinoitika yokutanga meno simba chaizvo kuchinja pakuzadzisa zvachose.
