Ndeupi achizadza zvinhu zvakanaka?

How kubvisa mazino? The yakanakisisa kuita - kushandisa ano zvekupfakira zvinhu. In dentistry, nokuti chinangwa ichi pane zvakasiyana mapoka fillers. Selection imwe sezvamunoita inotsamira zvinhu zvakawanda: ayo ehupfumi, kuchengeteka muviri, kukosha. Dzokumabvazuva murwere kubatsira zvinotevera muchidimbu zvinhu kuti mazino kurapwa.

Kuzadza zvinhu rakakamurwa marudzi anotevera:

1. amalgam Silver. Izvi zvinhu chaizvoizvo chakarasikirwa vaimbova mukurumbira wayo, zvisingachashandi, wePonto anenge asina kushandiswa. Inoitwa mekuri, riri zvikuru chepfu vapor. kushandiswa kwakapararira nesirivha amalgam mu dentistry kwakakonzerwa anoverengeka zvazvakanakira: simba, mukurumari, yakakwirira antibacterial zviratidzi yakaderera mutengo. Rinokosha payakaipira: yakaderera adhesion nokuti makorari mumakomba vanofanira kudzokorora kushanyira chiremba, dziine tsvina, dzisingatarisiki, uye anogona ndodzima secede zino rinenge toxicity nokusazvibata chisimbiso shoma.

2. Dental cements. Zvinowanzoshandiswa makore anenge makumi maviri apfuura. The yakanakisisa zvekupfakira zvinhu kubva boka iri, iro richiri kushandiswa - girazi ionomer simende. Zvinoumba: nesilicon, aruminiyamu, fluorine. Hazvina yakavhenganiswa nemvura kwakadonhera kana polyacrylic asidhi (50% mhinduro).

Advantages:

- anoomesa nokukurumidza - mukati kwemaminitsi mashoma;

- Anosarudza fluoro, kunoita patsva ane mazino zvinyama - rine musanganiswa ftoralyumosilikata uye polyacrylic asidhi (chakadaro chisimbiso ndiye kudzivirira dzokororo ine caries Zvisinei girazi ionomer simende hunokosha kunorapwa chinonyanya mazino);

- mwando nemishonga - zvinogona kushandiswa insulating lining, izvo inodzivirira zino rinenge kubva kukuvadza kunoita hasha;

- hakukuvadzi - hakurevi kutsvinyira pulp;

- yakakwirira adhesion - anokwanisa namarunda karusiyamu rakaoma mazino tishu.

3. rinoumba zvekupfakira zvinhu. The vakawanda kudiwa mumakore achangodarika. Rinoumba ine imwe makemikari chizvaro (chakaita zvokugadzirwa nebwe) uye inorganic filler (Goldstone upfu). Nokuti pakurapa posterior meno zvinhu rinoshandiswa hombe tudonhwe Goldstone, kupa simba zvakafanira kuti refu.

Zvakanakira chinoumbwa:

- abrasion musimbwa;

- utano chengetedzo;

- yakakwirira simba;

- Ndinoda of Use;

- yakanaka makorari;

- tinogona kushandiswa vakabudirira kudzorerwa mberi meno;

- yakakwirira aesthetic ehupfumi - Kunowanzurudza achizadza zvinhu kutevedzera dzinongoitika ruvara, magadzirirwo, pachena, i.e. migumisiro akaoma Gloss;

--siyana.

Possible yematambudziko:

- Kunzwisisa - kutyora kunoitika apo kurapwa unyanzvi, Bookmarks yakakwirira dose;

- nokukurumidza erasure kurasikirwa kana isina kukodzera vakanongazve kuzadza zvinhu, uyewo chinoumbwa hazvigoni kushandiswa pakurapa varwere yakawedzera abrasion kuti zino enamel;

- zino kuora, cleavage masvingo aro - harifaniri kushandiswa kudzorera chinoumbwa zvinhu rekorona ane zino rakaparadzwa neinopfuura 50%.

Saka, kusarudzwa imwe sezvamunoita mumakomba - simende, simbi kana polymer -better aivimba chiremba wemazino. Achaita kuongorora mamiriro mazino uye kupa yakanakisisa chingaitwa imwe murwere.
