Nke na-ejuputa ihe onwunwe kasị mma?

Olee otú iji kpochapụ ezé ure? The kasị mma nhọrọ - iji oge a na ndochi ihe. Na dentistry, n'ihi nzube a na e nwere iche iche iche iche nke fillers. Nhọrọ nke a akpan akpan mejupụtara na-adabere na ọtụtụ ihe: ya Njirimara, nche maka ahụ, uru nke. Ifu onye ọrịa na-enyere ndị na-esonụ nkenke nnyocha nke ihe maka eze ọgwụgwọ.

Ejuputa ihe onwunwe na-ekewa ndị na-esonụ ụdị:

1. Silver njikọta. Nke a ihe onwunwe n'ezie tụfuru ya mbụ ewu ewu, gharazie ịba uru, n'oge na-adịbeghị fọrọ nke nta adịghị mee ihe. Ọ mejupụtara mercury, nke bụ ukwuu na-egbu egbu vapors. Nile iji silver njikọta na dentistry bụ n'ihi ọtụtụ uru: ike, anwụ ngwa ngwa, elu antibacterial egosi ala na-eri. Ịrịba Ama ọghọm: ala adhesion maka polishing fillings ga ikwugharị nleta na nke dọkịta, unsightly, na ike daa mbà n'obi secede nha nha anụ ahụ toxicity rụrụ keokere akara.

2. Dental cements. Ọtụtụ-eji banyere afọ iri abụọ gara aga. The kacha mma ndochi ihe ọmụma si na otu a, nke ka na-eji - iko ionomer ciment. Mejupụtara: sịlịkọn, aluminum, fluorine. Ọ bụ mbuaha na distilled mmiri ma ọ bụ polyacrylic acid (50% ngwọta).

uru:

- siri ike ngwa ngwa - n'ime a nkeji ole na ole;

- ahọrọ fluoro, na-akwalite imu nke eze na anụ ahụ - mejupụtara a ngwakọta ftoralyumosilikata na polyacrylic acid (dị a akara na-mgbochi nke nlọghachite nke caries, Otú ọ dị iko ionomer cement dị oké mkpa maka ọgwụgwọ nke isi ezé);

- mmiri na-eguzogide - ike ga-eji dị ka ihe-egbochi ihe lining, nke na-echebe eze anụ ahụ si emebiri mmetụta nke ike ike;

- adịghị njọ - anaghị iwe na pulp;

- elu adhesion - bụ ike kee na calcium ike eze anụ ahụ.

3. The mejupụtara ndochi ihe. The kasị na ina na-adịbeghị anya. The mejupụtara mejupụtara ihe organic matriks (sịntetik resin) na ihe inorganic dịanyā (quartz powder). Maka ọgwụgwọ nke posterior ezé ihe onwunwe na-eji na ibu ahụ nke quartz, iji nye ndị dị mkpa ike ruo ogologo oge.

Uru nke composites:

- abrasion eguzogide;

- ahụ ike na nchekwa;

- elu ume;

- ala nke iji;

- mma polishing;

- ekwe omume nke ojiji maka ihe ịga nke ọma mweghachi nke n'ihu ezé;

- elu aesthetic Njirimara - maximizes ejuputa ihe iṅomi eke agba, udidi, nghọta, i.e. mmetụta nke akọrọ gloss;

- a dịgasị iche iche.

Ekwe Omume nsogbu:

- uche - mebiri na-adị mgbe ọgwụgwọ usoro, ibe edokọbara elu dose;

- ngwa ngwa erasure ọnwụ ma ọ bụrụ na-ekwesịghị ekwesị ẹmende ejuputa ihe onwunwe, nakwa ọtụtụ ihe mejupụtara ike ga-eji maka ọgwụgwọ nke ọrịa na ụba abrasion nke nha nha Enamel;

- nha nha ire ere, cleavage nke mgbidi ya - kwesịghị iji iji weghachi mejupụtara ihe onwunwe nke okpueze nke a nha nha ebibi ihe karịrị 50%.

N'ihi ya, nhọrọ nke a akpan akpan mejupụtara fillings - ciment, metal ma ọ bụ polima -better tụkwasịrị obi dọkịta eze. Ọ ga-amata ihe bụ ọnọdụ ndị ezé na-enye ihe kasị mma nhọrọ maka a akpan akpan ndidi.
