Kuphatikiza kwapakati ndi mawonekedwe, omwe minofu imene imatulutsa mthunzi wakumunsi imakhala yofanana ndipo imakhala yovuta kumbali zonse ziwiri. Chifukwa chaichi, pamene nsagwada zikuphatikizidwa, chiwerengero chachikulu cha mfundo zimayanjana, chomwe chimayambitsa kupangidwira kosayenera . Mitu yambiriyi nthawi zonse imakhala pansi pamtunda wa ng'ombe.
Zizindikiro za kusokonezeka pakati
Zizindikiro zazikulu za kutsekera pakati ndi:
- Chitsulo chilichonse chakumunsi ndi chapamwamba chimatseka ndi chosiyana ndi icho (kupatula pakatikati pamunsi ndi incisors zitatu);
- mu gawo lapambali, mwamtheradi mano onse otsika amafika pamwamba pa mano opambana ndi osapitirira 1/3 ya korona;
- Mzere wamtundu wapamwamba umagwirizana ndi mano awiri apansi, ophimba nawo 2/3;
- zikopa za nsagwada zam'munsi zimalumikizana kwambiri ndi mitsempha yapamtunda;
- chigwa chapafupi chomwe chili pamunsi mwa mthunzi chimakulungidwa ndi chapamwamba;
- Mafupa amtundu wa nsagwada pansi amapezeka pakati pa lingual ndi buccal;
- Pakati pa pansi ndi kumtunda kwapisors mzere wa pakati uli nthawi yomweyo.
Tsatanetsatane wa kusokonezeka pakati
Pali njira zingapo zodziwira zochitika zamkati:
- Njira yothandizira - mutu wa wodwalayo umabwerera, dokotala amaika zala zachindunji pamano a nsagwada kumunsi ndi malo am'mbali pamakona. Wodwala akukweza nsonga ya lilime, amakhudza pakamwa ndipo amawomba panthawi yomweyo. Pakamwa pakatha, mukhoza kuona momwe dentation imatseka.
- Njira yamagetsi - imapereka kugwiritsa ntchito chipangizo chomwe chimasunga kayendetsedwe ka nsagwada pa ndege yopanda malire. Poganizira kuti nthawi yayitali imakhala yopanda mano, nsagwada yamtundu imakakamizika kuchoka panyanja, kumangomangirira.
- Anatomical ndi zamakhalidwe njira - kukhazikitsa boma pa thupi mapeto a nsagwada.
