Ixabiso eliMninzi leHydroxyapatite 

Kwinkalo yezinto eziphilayo, kukho into edityaniswe ngaphakathi ekubunjweni kwamathambo namazinyo omntu: i-hydroxyapatite. Le minerali yenzeka ngokwemvelo ayisiyonto iphambili kuphela kwizicubu ezinzima zomntu kodwa ikwadlala indima ebalulekileyo kwezamayeza, ukhathalelo lomlomo, ubuhle bezonyango, kunye nesayensi yebhayoloji. Namhlanje, makhe singene nzulu kule nto imangalisayo.

I-Hydroxyapatite: Intshayelelo yeMveliso

I-Hydroxyapatite yiminerali ye-calcium phosphate eyenzeka ngokwemvelo kunye ne-chemical formula Ca₁₀ (PO₄) ₆ (OH) ₂, kwaye iyona nto iphambili kwi-inorganic component of vertebrate bones and teeth. Emzimbeni womntu, i-akhawunti ye-hydroxyapatite malunga ne-60-70% yezicubu zethambo kunye ne-90% yezinyo enamel.

Esi sixhobo sinesakhiwo sekristale esikhethekileyo, senkqubo yekristale enehexagonal, esinika iipropathi eziphezulu zomzimba kunye neekhemikhali. Itekhnoloji yanamhlanje ivumela ukuhlanganiswa kwe-hydroxyapatite ngeendlela ezahlukeneyo, kubandakanywa ne-hydrothermal synthesis, imvula, kunye neendlela ze-sol-gel, eyenza ukulawula okuchanekileyo phezu kobunyulu bayo, i-crystal structure, kunye ne-particle morphology ngokweemfuno ezahlukeneyo zesicelo.

Indlela yokwenza: Ukuhambelana kwe-Biocompatibility kunye ne-bioactivity

I-Hydroxyapatite ithandwa kakhulu kwintsimi ye-biomedical ngokuyinhloko ngenxa yeempawu ezimbini eziphambili:

I-Biocompatibility: Ngenxa yokuba i-hydroxyapatite iyinxalenye yamathambo namazinyo omntu, inobudlelwane bendalo kunye nezicubu zomntu kwaye ayibangeli ukugatywa okanye ukusabela okunobuthi.

I-Bioactivity: Xa i-hydroxyapatite idibana nezicubu eziphilayo, uchungechunge lweempendulo zenzeke kwi-interface ye-tissue-tissue, ukwenza iibhondi zeekhemikhali kunye nokukhuthaza ukukhula kwezicubu zethambo elitsha kumphezulu wayo. Le propathi ye-osteoconductive ikhokela iiseli zethambo ukuba zifuduke, zincamathele, kwaye zande kumphezulu wayo.

Kwinqanaba le-molecular, i-hydroxyapatite isebenzisana nezicubu ezijikelezayo ngokutshintshiselana kwe-ion. I-calcium kunye ne-phosphate ion kumphezulu wayo zinokutshintshiselana nge-biomolecules kulwelo lomzimba, ukukhuthaza iprotein adsorption kunye nokuncamathelwa kweseli, ngaloo ndlela iqalisa inkqubo yokulungisa izicubu.

Imisebenzi emininzi: ukusuka kunyango lwezonyango ukuya kukhathalelo lwemihla ngemihla

IHydroxyapatite inoluhlu olubanzi lwezicelo, ngakumbi kwezi ndawo zilandelayo:

Izicelo ze-Orthopedic: Njengesixhobo sokulungisa i-bone defect, isetyenziselwa ukuzalisa iziphene zamathambo ezibangelwa yintlungu, ukutshatyalaliswa kwe-tumor, okanye izifo ezizalwayo; njengento yokufakelwa kwethambo, idityaniswe kunye neepolymers ukuvelisa iipleyiti zethambo ezinokonakala, izikrufu zamathambo, kunye nezinye izixhobo zokulungisa zangaphakathi.

Intsimi yamazinyo: Isetyenziselwa ukuhlaziywa kwe-alveolar ridge, ukuzaliswa kwesokhethi yamazinyo, kunye nokulungiswa kwe-bone defect periodontal; njengesongezelelo se-toothpaste, inokubuyisela i-enamel yezinyo, ukulungisa i-caries yangaphambili, kunye nokunciphisa ngokufanelekileyo uvakalelo lwamazinyo.

Iinkqubo zokuhanjiswa kweziyobisi: Ngenxa yobume be-porous and adsorption properties, inokusetyenziswa njengomphathi weziyobisi ukuphumeza ukukhutshwa kweziyobisi okujoliswe kuyo kunye nokugcinwa okuqhubekayo.

Iyeza le-Cosmetic: Njengokugcwalisa izicubu ezithambileyo, isetyenziselwa ukujika ubuso kunye nokuzaliswa kwemibimbi, inikezela ngenye indlela ekhuselekileyo nehlala ixesha elide kwizihluzi zemveli.

IHydroxyapatite, njengesixhobo esine-biocompatible kakhulu, inceda abantu abaninzi ukuba bakhe amathambo aqinileyo, amazinyo kunye nezicubu ezisempilweni. Ukusetyenziswa kwenzululwazi kwesi simbiwa sendalo sibonisa ngokugqibeleleyo ukuhlalisana okuhambelanayo kwendalo kunye nobuchwepheshe, kwaye kukwalatha indlela yophuhliso lwexesha elizayo lwe-biomaterials.
