Endodontic zviridzwa. Description pakubhadhara siyana

Endodontic Zviridzwa anoshandiswa mazino manipulations ari mhango uye mudzi migero yose zino. Izvi zvokushandisa inokosha kubva kabhoni simbi kana nickel-titanium chiwanikwa. Zvinokosha kucherechedza kuti zviridzwa zvakagadzirwa nickel-titanium chiwanikwa, zvikuru kuchinja, vane rakachengeteka pamusoro uye "chimiro ndangariro". Vari kubva kunyorwa kwezvinhu dzeraundi muchinjikwa chikamu zvamakaparadza uye kushandiswa chaiwo pasi-nokukurumidza chibooreso uye Chinyorwa basa. Nokuti zvivanakire vanachiremba endodontic zviridzwa zvose vane zvavo yeEncoding pachavo inokosha. The Codes kuuya munzira dzakawanda.

The Numeric Codes vari aishanda zvakananga mubato (paruoko Ezvemutauro) kana kavha (zvokushandisa chibooreso). nhamba nerimwe ndiro dhayamita iyo runoratidzwa hundredths ane millimeter.

Geometric Bumbiro (zononoka, mativi, Triangle, Zimbabwe Educational, denderedzwa) rinoratidza munhu-chikamu muchinjikwa ari kushanda rutivi.

Color yekubvuma zvinosanganisira mavara matatu zvenguva uye matanhatu makuru. Ruvara rinoreva turusi chisarudzo. Panguva Canal kurapwa chiremba haafaniri kurovha chete ruvara.

Tools rakagadzirirwa Chinyorwa oparesheni, angakudzivisai tembiricha kusvika madhigirii mazana maviri Celsius. Zvinosanganisira munhu mubato kuna zvandinenge geometric, uye digitaalinen mavara-coded, uye kushanda chikamu ayo zvakabatanidzwa neshamhu. Shamhu ane kureba 21 kusvika 31 mm uye kushanda chikamu nguva dzose ane kureba 16 mm. Mumwe mudziyo ane silicone chimiso. Ari zvaipfekwa zvakananga patsvimbo uye ane Achisiyanisa divi, izvo zvinoratidza gwara vanobwembura.

Endodontic Zviridzwa zvokushandisa mudzi migero ndiwo:

1. Nokuti extirpation yacho pulp. The turusi anotarira yakafanana rasp, uye ane mazino. Mazino vane yakaderera mufambo, saizi wavo idukusa kaviri netsvimbo dhayamita. Kana chishandiso iri achinyatsotaurira mudzi canal, mazino vari aimanikidzwa nomubato, uye kana vari anombotwasanudza uye mokusvinwa ane kubatwa pulp rinenge kana detritus. Kune miganhu nomwe chokushandisa ichi.

2. Kuti tizive kudzama mudzi migero uchishandisa tsono. Vari zvakagadzirirwa kuona kukura pamuchinjikwa-migero. Tsono kuuya hukuru shanu.

3. Chokuwedzera mumuromo mugero, kushandiswa chaiye expander, Zvinonzi donhwe-nokushanda chikamu. turusi akadaro inowanika ine-sectional matanhatu miganhu.

4. Kuti kuwedzera yakamanikana yaNire curved, shandisa endodontic zviridzwa inokosha akafanana rasp. Yakatarwa zvinosanganisira Ezvemutauro nomwe ane kureba 25 mm netsvimbo. On basa pamusoro varipo meno makumi mashanu, izvo akaronga kuti mudziyo akabatana pa necheparutivi. Kureba mazino katatu duku pane chishandiso dhayamita. Muromo mazino anogona nyore zvinokambaira chiteshi.

Michina mazino zvishandiso, akaita chinhu chiwanikwa kuti nickel uye titanium, vane taper guru. Naizvozvo, dhayamita neimwe vaivapo yakawanda 290/0. Izvi zvinobvumira dzakafanana Zvakawanikwa mudzi Canal. Woita micheto uye chimiro kunobatanidza kudzivirira jamming yacho chokushandisa. Blunt muromo unokubvumira abate mudziyo nenzira kupa kunyange nzvimbo hombe vanobwembura, rinovatadzisa kusikwa zvigaro uye perforation. hukuru avo vari kubva 15 N 150 N.

Rinoshanda endodontics zvokushandisa pamusoro apa, uyewo dzinokosha zvishandiso - condensers pamwe zononoka serin'i anokosha cheka.
