Mazino dzevanhu

mazino Human - dzidzo yakasimba, izvo dziri mune Formação de pakati shaya. Ndivo chinokosha zvikamu muchina, ane basa iri kutsenga nayo. meno dzevanhu vane yakakwirira vanokwanisa Kusiyanisa. Ndivo duku zvikuru tichienzanisa kuti genus kuti tsoko.

Kune mapoka mana kwemeno: molars, premolars, incisors, canines. In dentistry kufanana inotungamirwa yakakamurwa parutivi uye mberi. Murume makore manomwe kushanda kwenguva meno, izvo zvino achinja kuva echigarire. Izvi nhamba dziri pasi zvakasiyana, izvo anokonzerwa peculiarities muviri uye zvakatipoteredza. Kwemakore 32 ipapo okupedzisira meno ichi mhando. Saka, kuziva kuti mazino zhinji munhu anogona chete kuva muzera rino. mari iyi yakaenzana 32. okupedzisira mazino kazhinji akaderedzwa, dzimwe nguva havaiti kuputika. Pane rinokosha inonyatsoita kuti huwandu mapfupa inotungamirwa Data. Inonzi zino. In vakuru, ndizvo sezvinotevera: zvitatu molars, vaviri premolars, mumwe canine, zviviri incisors norumwe hafu vaviri shaya.

Anatomy kwemeno dzevanhu

Kune zvikamu zvitatu inotungamirwa ichi: korona, mudzi mutsipa. Inside neimwe zino chinhu mhango, iyo rakakamurwa kuva mudzi Canal uye mhango rekorona. Kuburikidza mugomba chakaderedzwa mutengo riri tsinga, midziyo kuti tibu- dzose kushanda nenyere. Ivo anowanikwa pulp, uko kunomiririrwa nzenza connective tishu. Wall kuti zvakananga ndowenyika dög pose nezino inonzi denga.

In dentistry netsika kusiyanisa ina pamusoro idzodzo Data: vestibular, lingual, masticatory (Y premolars uye molars - clamping Ndege) kuonana. Mirau yakatangwa zvakananga kuzviongorora. Korona uye mudzi muzvikamu zvitatu zvinoti: occlusal, pakati, remuromo retatu.

meno dzevanhu vane kunzwisisa sezvamunoita. Ivo kuumbwa dentine, uko kunomiririrwa kostepodobnoy jira zvinosanganisira odontoblasts. The Zvinoumba yokupedzisira inosanganisira chicherwa munyu (karusiyamu fluoride, magnesium phosphate, karusiyamu phosphate) uye Organic fibers (collagen).

zino korona rinofukidza kunyanya chakasimba fuma - the enamel, iyo inovakwa pamusoro prisms kuti vane Ukobvu 3-5 microns. Inoitwa chicherwa munyu zvakafanana avo vari dentin.

Mutsipa uye mudzi akafukidzwa simende - a fuma chinoratidza pfupa. Inoitwa 30% kuti makemikari zvinhu (collagen), rwugare vasara kurema chicherwa munyu (karusiyamu carbonate, karusiyamu phosphate).

All yedzidzo zvokuudzwa kukabatanidzwa pasi rokuti: dentition. It ane kunzwisisa akanyatsorongwa uye inosanganisira periodontium, tsandanyama, majoini, mate omumuviri, mazino. ino inopa mashandiro anoita dög uye rinobatanidzwa paumbwe kutaura.

Mazino mhandu anonzi osculating inotungamirwa repamusoro mandible. Bone nhengo iri kuruboshwe uye kurudyi dzinonzi antimeres.

The spatial ukama pakati shaya uye dentition nokuda kufamba zvose zvinonzi nekunyatsotsanangura. Kunyanya chimiro rokuti ndiye occlusion, zvakatemwa nokuvhara idzodzo izvi panguva kutsenga. Chinhu kutituma pakugadzirwa ane occlusion.

Iri izwi rinoreva nhamba rokumusoro, nechepazasi dentition panguva kuvhara zviri shaya. Zvinotevera zvokuzvivaraidza malocclusion: alveolar Arch iri chete pachiyero, mumwe wavo riri pamberi mumwe. Vasiri vaiona ezvinhu umo yokumusoro mutsara mazino ari zvishoma haachatauri mberi panyaya pasi. Zvisinei, pasi siyana pathological ezvinhu ari nemumuromo mhango, kunotevera, occlusion dzingasiyana. meno Human muchiitiko ichi, vanogona kuchinja chimiro chavo uye sezvamunoita.
