Nemhaka yeizvi, apo masaya acho akabatanidzwa, huwandu huwandu hunoti hune humwe hunobatana, hunoita kuti kuumbwa kwemaitiro asina kukodzera . Iyo misoro yemajoka inogara iri padzivi padzika remhuru.
Zviratidzo zvepakati pemazuva
Zviratidzo zvikuru zvekushandiswa kwepakati ndezvi:
- rimwe nerimwe rakaderera nepamusoro mazino rinopfigira nechokunopesana naro (kunze kwerutivi rwezasi pasi incisors uye mitatu yepamusoro molars);
- muchikamu chekutanga, zvachose mazino ezasi anokwira mazino ekumusoro asingapfuuri katatu kwekorona;
- iyo yepamusoro yepamusoro molar inobatanidza nemazino maviri pasi, inovafukidza ne2/3;
- iyo incisors yejaya rakaderera zvakanyatsobatana neatatal tubercles yejaya rekumusoro;
- zvinyorwa zvepachipfuva zviri kumucheto wezasi zvakaputirwa nepamusoro;
- Ma tubercles anouraya ejaya riri pasi anowanikwa pakati pezvinyorwa uye zvakasiyana;
- Pakati pezasi nepamusoro incisors mutsetse wepakati unogara uri mundiro imwe chete.
Tsanangudzo yepakati pekushandiswa
Kune nzira dzakawanda dzekugadzirisa hutachiona hunowanikwa:
- Nzira yekushanda - mushonga wemurwere unodzokera shure, chiremba anoisa menoji yeminwe pameno ejaya riri pasi uye anogara makona anokosha mumakona emuromo. Murwere anosimudza rutivi rworurimi, anobata muromo uye anoputika panguva imwe chete. Apo muromo unovhara, unogona kuona kuti dentition inoguma sei.
- Chigadzirwa chekushandisa - inopa kushandiswa kwechigadziri chinonyora kushambadzira kwemajaya mu ndege yakanyanyisa. Kana uchitarisa kuvepo kwepakati nekusavapo kwemazino zvishoma, tsvina yakadzika inokurumidza kusimuka paruoko, ichidzvinyirira chidimbu.
- Anatomical uye nzira dzepanyama - kusarudza kwehurumende pane zororo rehupenyu hwemasara.
