Agaciro kinshi ka Hydroxyapatite 

Mu rwego rwa biomaterial, hari ibintu bifitanye isano imbere yibigize amagufwa y amenyo y amenyo: hydroxyapatite. Iyi myunyu ngugu isanzwe ntabwo igizwe gusa ningingo zikomeye zumubiri wumuntu ahubwo inagira uruhare runini mubuvuzi, kuvura umunwa, ubwiza bwubuvuzi, na siyanse ya biomaterial. Uyu munsi, reka twinjire cyane muriyi ngingo idasanzwe.

Hydroxyapatite: Kumenyekanisha ibicuruzwa

Hydroxyapatite ni imyunyu ngugu ya calcium fosifate isanzwe hamwe na formula ya chimique Ca₁₀ (PO₄) ₆ (OH) and, kandi nikintu nyamukuru kidasanzwe kijyanye namagufa yintegamubiri n amenyo. Mu mubiri w'umuntu, hydroxyapatite igera kuri 60-70% by'ingirangingo z'amagufwa hamwe na 90% by'amenyo y'amenyo.

Ibi bikoresho bifite imiterere yihariye ya kirisiti, ijyanye na sisitemu ya sisitemu ya mpandeshatu, itanga imiterere yumubiri nubumara. Ikoranabuhanga rigezweho ryemerera synthesis ya hydroxyapatite binyuze muburyo butandukanye, harimo hydrothermal synthesis, imvura, nuburyo bwa sol-gel, bigafasha kugenzura neza ubuziranenge bwabyo, imiterere ya kirisiti, hamwe na morphologie ukurikije ibisabwa bitandukanye.

Uburyo bwibikorwa: Biocompatibilité na bioactivite

Hydroxyapatite itoneshwa cyane murwego rwibinyabuzima cyane cyane kubintu bibiri byingenzi biranga:

Biocompatibilité: Kubera ko hydroxyapatite igizwe namagufa y amenyo y amenyo yabantu, ifitanye isano karemano ninyama zabantu kandi ntabwo itera kwangwa cyangwa reaction yuburozi.

Bioactivite: Iyo hydroxyapatite ihuye nuduce twizima, urukurikirane rwibintu bibera kumubiri-tissue, bigakora imiyoboro ya chimique kandi bigatera imbere gukura kwimitsi mishya yamagufwa hejuru yacyo. Iyi mitungo ya osteoconductive iyobora ingirangingo zamagufa kwimuka, kugerekaho, no kwiyongera hejuru yacyo.

Kurwego rwa molekile, hydroxyapatite ikorana nuduce dukikije binyuze mu guhana ion. Kalisiyumu na fosifate ion hejuru yacyo birashobora guhanahana na biomolecules mumazi yumubiri, bigatera poroteyine adsorption hamwe na selile, bityo bigatangira inzira yo gusana ingirangingo.

Imikorere myinshi: kuva kwivuza kugeza kubuvuzi bwa buri munsi

Hydroxyapatite ifite porogaramu zitandukanye, cyane cyane mubice bikurikira:

Porogaramu ya orthopedie: Nibikoresho byo gusana amagufwa, bikoreshwa mukuzuza inenge zamagufa ziterwa nihungabana, kuvura ibibyimba, cyangwa indwara zavutse; nkibikoresho byamagufwa, byongewemo na polymers kugirango bibyare amasahani yamagufwa yibinyabuzima, imigozi yamagufa, nibindi bikoresho byo gutunganya imbere.

Umwanya w'amenyo: Yifashishwa mu kwiyubaka kwa alveolar, kuzuza amenyo, no gusana amagufwa ya parontontal; nk'inyongera ry'amenyo, irashobora kwibutsa amenyo amenyo, gusana karies kare, kandi bikagabanya neza ibyiyumvo byinyo.

Sisitemu yo gutanga ibiyobyabwenge: Bitewe nuburyo bubi hamwe na adsorption, irashobora gukoreshwa nkabatwara ibiyobyabwenge kugirango igere ku ntego kandi irambye.

Ubuvuzi bwo kwisiga: Nkuzuza imyenda yoroheje, ikoreshwa muburyo bwo mumaso no kuzuza inkari, bitanga ubundi buryo bwizewe kandi burambye burigihe kubuzuza gakondo.

Hydroxyapatite, nkibikoresho bihuza cyane, ifasha abantu batabarika kubaka amagufwa akomeye, amenyo, hamwe nuduce twiza. Ikoreshwa rya siyansi ryimyororokere karemano ryerekana neza kubana kwa kamere hamwe nikoranabuhanga, kandi bikerekana inzira yiterambere ryigihe kizaza ryibinyabuzima.
