I-Hydroxyapatite (HA) yimpahla ye-bioceramic eneembono ezibanzi zokusetyenziswa. Kwiminyaka yakutshanje, ngokuqhubeka kwabantu befuna ubomi obunempilo kunye nobuchwepheshe bezonyango, i-HA isetyenziswe ngakumbi nangakumbi kwiinkalo zonyango kunye nonyango lwamazinyo, kwaye iye yaba yintandokazi entsha yezobuchwepheshe bezonyango.
Ukubunjwa kweekhemikhali ze-hydroxyapatite kufana neyona nto iphambili yethambo lomntu, ngoko ke ihambelana ngokuqinileyo nezicubu zomntu kwaye ayiyi kubangela ukugatywa. Oku kuyenza ibe yimathiriyeli efanelekileyo ye-bioactive, enokusetyenziswa okubalulekileyo kwinkalo yokulungiswa kwesiphene samathambo, ukufakelwa kwamazinyo, kunye nokubuyiselwa komlomo.
Kwinkalo yokulungiswa kwesiphako samathambo, i-hydroxyapatite isetyenziswa ngokubanzi ekulungiseni nasekuvuseleleni iifractures, iziphene zamathambo kunye namathambo amathambo. Umphezulu wayo we-bioactive unokudibanisa kunye nezicubu zethambo ezijikelezileyo kwaye zifakwe ngokuthe ngcembe ukukhuthaza ukukhula kwethambo elitsha, ngaloo ndlela kukhawulezisa isantya sokulungiswa kwamathambo kunye nokuphilisa. Ukongezelela, i-hydroxyapatite ingasetyenziselwa ukufaka izixhobo ezincedisayo ezifana nezihlanganisi ezenziweyo, iibrakethi kunye nezikrufu ukubonelela ngenkxaso eyongezelelweyo yamathambo kunye nokukhuthaza ukuvuselelwa kwamathambo.
Kwintsimi yamazinyo, i-hydroxyapatite isetyenziselwa unyango lwezilonda ze-pulp yamazinyo, ukuvuselelwa kwe-pulp yamazinyo kunye nokufakelwa kwamazinyo. Ine-biocompatibility egqwesileyo kunye ne-bioactivity, kwaye inokudibanisa ngokugqibeleleyo kunye nezicubu zethambo lamazinyo ukukhuthaza ukuvuselelwa kwamazinyo kunye nokubuyiselwa. Kwangaxeshanye, i-hydroxyapatite inokusetyenziselwa ukwenza izinto zokuzalisa amazinyo ukuzalisa i-carious cavities kunye nokubuyisela nokukhusela amazinyo.
Ukongezelela, i-hydroxyapatite iphinda isetyenziswe kwezinye izicelo kwintsimi yezonyango, njengokulungiswa kwamathambo okwenziwa, abathwali beziyobisi, ubunjineli bezicubu, njl. kumzimba womntu. Ngenxa yeenzuzo zayo ezininzi kwiinkalo zesayensi yezinto eziphathekayo kunye neyeza, i-hydroxyapatite yamkelwa ngokubanzi kwaye isetyenziswa kwiinkalo ezininzi.
Nangona kunjalo, ukusetyenziswa kwe-hydroxyapatite kukwajongene nemingeni ethile. Okokuqala, umsebenzi wayo webhayoloji kunye nesantya sokufunxa kufuneka ulawulwe ngakumbi kwaye ulungelelaniswe ngcono kwiimfuno ezahlukeneyo zonyango. Okwesibini, iteknoloji yokulungiselela kunye nokulawulwa kwekhwalithi ye-hydroxyapatite nayo kufuneka iphuculwe ngokuqhubekayo ukubonelela ngeemveliso ezingcono.
Ngokubanzi, i-hydroxyapatite, njenge-biomaterial eneembono ezibanzi zokusetyenziswa, iya kuzisa umfutho omkhulu kwimpilo yabantu kunye nokhathalelo lwezonyango. Kwixesha elizayo, sinokulindela usetyenziso olongezelelweyo lwe-hydroxyapatite kwi-orthopedics, amazinyo, kunye nezinye iindawo zonyango ukuhlangabezana nokusukela ngokuqhubekayo kwabantu impilo kunye nokhathalelo lwezonyango olukumgangatho ophezulu.
