HAp yo gusaba amenyo: Inyungu, Ibipimo, hamwe nuyobora abaguzi 

Intangiriro

Hydroxyapatite (HAp) ibaye kimwe mubintu byingenzi bya biomateriali mubuvuzi bw'amenyo ya kijyambere kubera imiterere ihuye na emamel yumuntu hamwe namabuye y'amagufwa. Mugihe ibyifuzo byiyongera kubikoresho by amenyo biocompatibilité kandi bivugurura, abayikora baragenda bashakisha ifu ya HAp yo mu rwego rwohejuru yoza amenyo, imiti igabanya ubukana, insimburangingo yamagufwa, hamwe nandi mavuta.

Nyamara, ibikoresho byose bya hydroxyapatite ntabwo byujuje ubuziranenge bwa tekiniki bukenewe mu gukoresha amenyo. Ingano nini yo gukwirakwiza, ubuziranenge, kristu, hamwe no kugenzura ibyuma biremereye bigira ingaruka kumikorere n'umutekano.

Aka gatabo karasobanura uburyo HAp ikoreshwa mubuvuzi bw'amenyo, ibisobanuro bya tekiniki bifite akamaro kanini, nuburyo bwo guhitamo hydroxyapatite itanga isoko yizewe yo kuvura amenyo.

Hydroxyapatite Niki n'impamvu bifite akamaro mubuvuzi bw'amenyo

Hydroxyapatite (Ca₁₀ (PO₄) ₆ (OH) ₂) ni ibintu bisanzwe biboneka muri calcium ya fosifate igizwe na 70% by'amenyo y'amenyo y'abantu hamwe n'amabuye y'agaciro.

Kubera imiterere ya biomimetike, HAp ikoreshwa cyane mugukoresha amenyo aho biocompatibilité na remineralisation ari ngombwa.

Ibyiza byingenzi birimo:

• Biocompatibilité nziza

• Imiterere ya emamel

• Ubushobozi bwo guteza imbere remineralisation

• Umwirondoro muto

• Gukomera cyane hejuru yinyo

Ibiranga bituma HAp isimburwa nuburyo busanzwe bwa fluoride ishingiye kuri sisitemu zimwe.

Ibyingenzi byingenzi by amenyo ya HAp

1. Ibinyo byinyo hamwe nibicuruzwa byibutsa

Nano hydroxyapatite isanzwe ikoreshwa muburyo bwoza amenyo kuri:

• Sana inenge ya micro-enamel

• Mugabanye kumva amenyo

• Kunoza neza ubuso

• Kongera ingaruka zo kwera

Ingano y'ibice igira uruhare runini hano. Nano-nini ya HAp itanga ubuso bwiza bwo kwinjirira no kwinjira muri micro-pore.

2. Gutanga abakozi

HAp irashobora kubamo amenyo yinyo, kugabanya umuvuduko wamazi no kugabanya amenyo. Ugereranije na chimens desensisizeri zimwe, hydroxyapatite itanga biomimetike kandi igisubizo kirambye.

3. Gufata amagufwa mu kubaga amenyo

4

Muri implantology no kubaga parontontal, hydroxyapatite yo murwego rwo kwa muganga ikoreshwa nka:

• Gusimbuza amagufwa

• Scafold yo kuvugurura amagufwa

• Ibikoresho byo gutwikira amenyo

Muri ibi bihe, ubuziranenge, kristu, hamwe nuburinganire burenze cyane ibikoresho byo kwisiga.

4. Kwimika

Hydroxyapatite itwikiriye yongerera osseointegration hagati yatewe n'amagufwa. Icyiciro cya HAp kigomba kwerekana:

• Kugenzura kristu

• Icyiciro cyo hejuru

• Ubushobozi bukomeye bwo gufatira hamwe

• Ikigereranyo gihamye cya calcium / fosifate

Ibisobanuro bya tekiniki ya Dent-Grade Hydroxyapatite

Mugihe ushakisha HAp kubisabwa amenyo, ababikora bagomba kugenzura:

✔ Ubuziranenge

Amenyo yo mu rwego rwohejuru HAp mubisanzwe arenga 95-99% byera bitewe nubwoko bwa porogaramu.

Ingano Ingano Ikwirakwizwa

• Nano HAp: mubisanzwe <100 nm (umuti wamenyo na remineralisation)

• Micro HAp: ibice binini byo gushushanya porogaramu

Ingano imwe yingirakamaro iteza imbere guhuza no guhuza ibinyabuzima.

Ikigereranyo cya Ca / P.

Ikigereranyo cyiza cya calcium-kuri-fosifate igereranijwe ni 1.67, ihuye neza na emamel karemano.

Lim Imipaka iremereye

Kwipimisha cyane kubiyobora, arsenic, kadmium, na mercure ni ngombwa kubicuruzwa bikoreshwa mu kanwa.

Control Kugenzura mikorobe

Kubisabwa mubuvuzi cyangwa kubaga, kwemeza sterilisation no kugenzura endotoxine ni ngombwa.

Nano vs Micro Hydroxyapatite mugukoresha amenyo

Gusobanukirwa itandukaniro bifasha ababikora guhitamo ibisobanuro bikwiye.

Ibitekerezo byo kugenzura no gukora

Ibikoresho by'amenyo bigomba kubahiriza amabwiriza y’ibanze akurikije amasoko yagenewe. Mugihe uhitamo hydroxyapatite itanga, tekereza:

• Ubushobozi bwo gukora GMP

• Icyemezo cya ISO

• Gukurikirana neza

• Igenzura rihoraho rya Ca / P.

• Inkunga yohereza hanze

Kubaga-urwego rwa HAp, kwemeza byongeweho nkuburyo bwo kuboneza urubyaro birashobora gukenerwa.

Nigute wahitamo Hydroxyapatite Yizewe yo gutanga amenyo

Mbere yo gutanga ibicuruzwa byinshi, suzuma:

Gukora mu mucyo
Icyemezo kirambuye cyo gusesengura (COA)
Raporo y'ibipimo by'ibipimo
Ibyuma byo gupima ibyuma biremereye
Gufata amateka ahoraho
Ubunararibonye butanga abakora amenyo cyangwa abaganga

Uruganda rukora hydroxyapatite rugomba gutanga ubufasha bwa tekiniki mugihe cyo gutegura no gutegura amabwiriza.

Ibibazo: HAp yo gusaba amenyo

Nano hydroxyapatite ifite umutekano kubi menyo?

Iyo bikozwe neza kandi bipimwa kubwera nibyuma biremereye, nano hydroxyapatite ifatwa nkumutekano kubuvuzi bwo mu kanwa.

Ni ikihe kigereranyo cya Ca / P gikwiye kumenyekanisha amenyo HAp?

Hafi ya 1.67 kugirango usa neza amenyo karemano ya emamel.

Hydroxyapatite isimbuza fluor?

HAp irashobora kuba ubundi buryo bwo kwibutsa ibintu muburyo bumwe, nubwo imyanya ihindagurika itandukana mukarere.

Ni irihe tandukaniro riri hagati yo kwisiga-urwego rwubuvuzi-HAp?

Ubuvuzi-bwo mu rwego rwa HAp busaba kugenzura neza isuku, kwemeza sterility, hamwe ninyandiko ugereranije nibikoresho byo kwisiga.

Umwanzuro

Hydroxyapatite igira uruhare runini mugukoresha amenyo agezweho kuva kumiti yinyo yinyo kugeza kubisimbuza amagufwa hamwe no gutwika. Guhitamo ingano yukuri, urwego rwubuziranenge, hamwe ninganda zikora ningirakamaro mubikorwa, umutekano, no kubahiriza amabwiriza.

Ku bakora ibicuruzwa bashaka isoko ryinshi rya hydroxyapatite yo mu menyo, gusuzuma neza ibisobanuro bya tekiniki, ibyangombwa byujuje ubuziranenge, hamwe n’ibipimo ngenderwaho byerekana ko bizerwa igihe kirekire kandi bikagenda neza.
