IHydroxyapatite (HA) iyimpahla ye-bioceramic enamathemba okusebenza abanzi. Eminyakeni yamuva nje, ngokuphishekela kwabantu okuqhubekayo kwempilo enempilo nobuchwepheshe bezokwelapha, i-HA iye yasetshenziswa kakhulu emkhakheni wezokwelapha nowodokotela bamazinyo, futhi isiyintandokazi entsha yobuchwepheshe bezokwelapha.
Ukwakheka kwamakhemikhali e-hydroxyapatite kufana nengxenye eyinhloko yezicubu zethambo lomuntu, ngakho-ke inokuhambisana okuqinile nezicubu zomuntu futhi ngeke kubangele ukwenqatshwa. Lokhu kuyenza ibe into efanelekile ye-bioactive, enamandla okusebenza abalulekile emikhakheni yokulungisa ukukhubazeka kwamathambo, ukufakwa kwamazinyo, nokubuyiselwa komlomo.
Emkhakheni wokulungiswa kwe-bone defect, i-hydroxyapatite isetshenziswa kabanzi ekulungiseni nasekuvuseleleni ama-fractures, ukukhubazeka kwamathambo kanye nezimila zamathambo. I-bioactive surface yayo ingahlangana nezicubu ezizungezile zethambo futhi ifakwe kancane kancane ukuze ikhuthaze ukukhula kwethambo elisha, ngaleyo ndlela kusheshiswe isivinini sokulungisa nokuphulukiswa kwamathambo. Ngaphezu kwalokho, i-hydroxyapatite ingase isetshenziselwe ukutshala amadivaysi asizayo njengamajoyini okwenziwa, amabakaki nezikulufu ukuze anikeze ukwesekwa kwamathambo okwengeziwe nokukhuthaza ukuvuselelwa kwamathambo.
Emkhakheni wamazinyo, i-hydroxyapatite isetshenziswa ekwelapheni izilonda ze-pulp yamazinyo, ukuvuselelwa kwe-pulp yamazinyo kanye nokufakelwa kwamazinyo. Ine-biocompatibility enhle kakhulu kanye ne-bioactivity, futhi ingahlangana ngokuphelele nezicubu zethambo lamazinyo ukukhuthaza ukuvuselelwa nokubuyiselwa kwamazinyo. Ngasikhathi sinye, i-hydroxyapatite ingasetshenziswa futhi ukwenza izinto zokugcwalisa amazinyo ukugcwalisa imigodi ye-carious nokubuyisela nokuvikela amazinyo.
Ngaphezu kwalokho, i-hydroxyapatite iphinde isetshenziswe kwezinye izinhlelo zokusebenza emkhakheni wezokwelapha, njengokulungiswa kwamathambo okufakelwa, abathwali bezidakamizwa, ubunjiniyela bezicubu, njll. Ine-biodegradability enhle, ingathathwa ngumzimba womuntu, futhi ngeke ibangele imiphumela emibi. emzimbeni womuntu. Ngenxa yezinzuzo zayo eziningi emkhakheni wesayensi yezinto ezibonakalayo kanye nemithi, i-hydroxyapatite yaziwa kabanzi futhi isetshenziswa emikhakheni eminingi.
Kodwa-ke, ukusetshenziswa kwe-hydroxyapatite nakho kubhekana nezinselelo ezithile. Okokuqala, umsebenzi wayo webhayoloji nezinga lokumunca kudingeka ulawulwe futhi ulungiswe ukuze uvumelane kangcono nezidingo zokwelapha ezahlukahlukene. Okwesibili, ubuchwepheshe bokulungiselela kanye nokulawulwa kwekhwalithi ye-hydroxyapatite nakho kudingeka kuthuthukiswe ngokuqhubekayo ukuze kuhlinzekwe ngemikhiqizo engcono kakhulu.
Sekukonke, i-hydroxyapatite, njenge-biomaterial enamathemba abanzi okusebenza, izoletha umfutho omkhulu empilweni yabantu nasekunakekelweni kwezokwelapha. Ngokuzayo, singalindela ukusetshenziswa okwengeziwe kwe-hydroxyapatite kudokotela wamathambo, udokotela wamazinyo, nakweminye imikhakha yezokwelapha ukuze kuhlangatshezwane nokuphishekela kwabantu okuqhubekayo kwezempilo nokunakekelwa kwezempilo kwekhwalithi ephezulu.
