Icandelo le-β-TCP lifana nokubunjwa kwamaminerali amathambo kwaye i-amorphous powder emhlophe engenavumba. Izinzile emoyeni, ibolile emanzini ashushu, i-soluble kwi-dilute hydrochloric acid kunye ne-nitric acid, ephantse ingabi namanzi, i-ethanol kunye ne-acetic acid. Ukuhambelana kakuhle kwebhayoloji, ukuthotywa phantsi kwemekobume yendalo, ukufunxwa zizicubu.
I-β-tricalcium phosphate (β-TCP) ine-biodegradability efanelekileyo, i-biocompatibility kunye nekhono le-osteoinductive. Emva kokufakwa emzimbeni womntu, i-calcium kunye ne-phosphorus ethotyiweyo ingangena kwinkqubo yokuphila kwaye yenze ithambo elitsha, ngoko isetyenziswa ngokubanzi. Lungisa izicubu zethambo. Nangona kunjalo, ukuqina kwayo akulunganga, kubhityile, kwaye amandla okuthwala imithwalo aphantsi. I-Poly L-lactic acid (PLLA) iphinde isetyenziswe ekulungiseni izicubu zethambo ngenxa ye-biocompatibility efanelekileyo kunye ne-biodegradability.
I-Tricalcium phosphate ine-biocompatibility efanelekileyo, i-bioactivity kunye ne-biodegradability. Yeyona nto ifanelekileyo yokulungisa izicubu eziqinileyo kunye nezinto ezitshintshileyo zomzimba womntu kwaye ibijongwe kakhulu kwicandelo lobunjineli bebhayoloji. Uhlobo olukhethekileyo lwe-tricalcium phosphate, i-beta-tricalcium phosphate, isetyenziswa ngokuqhelekileyo kumayeza. I-biocompatibility elungileyo, i-bioactivity kunye ne-biodegradability. Yeyona nto ifanelekileyo yokulungisa izicubu eziqinileyo kunye nezinto ezitshintshileyo. Njengempahla ekrwada yethambo eyenziweyo, isetyenziswe ngokubanzi kwi-orthopedics, utyando lweplastiki kunye notyando lokuthambisa, utyando lwamazinyo, ukulungiswa ngenxa yokwenzakala, iziphene zamathambo kunye nokudityaniswa kwamathambo okubangelwa ngamathumba, ukuvuvukala, izifo zamathambo, njl. Ekutyeni njengesongezelelo sesondlo esikhuselekileyo sokwandisa ukutya kwekhalsiyam, kwaye ingasetyenziselwa ukuthintela okanye ukunyanga iimpawu zokunqongophala kwekhalsiyam. Ngexesha elifanayo, linokusetyenziswa njenge-anti-caking agent, i-pH adjuster, i-agent agent, njl.
I-β-tricalcium phosphate ikakhulu yenziwe nge-calcium kunye ne-phosphorus, kwaye ukubunjwa kwayo kufana ne-inorganic component ye-bone matrix, kwaye idibene kakuhle nethambo. Izilwanyana okanye iiseli zomntu zinokukhula, zihluke kwaye ziphindaphindeke kwizinto ze-β-tricalcium phosphate. Ngenani elikhulu lezifundo zovavanyo, kungqinwe ukuba i-β-tricalcium phosphate ayinazo iziphumo ezibi kumongo wethambo umsebenzi we-hematopoietic, akukho mpendulo yokwala, akukho mpendulo yetyhefu ebukhali, akukho mhlaza, akukho nto yala. Ngoko ke, i-β-tricalcium phosphate ingasetyenziswa ngokubanzi kwi-joint and spinal fusion, i-trauma yamalungu, utyando lomlomo kunye ne-maxillofacial, utyando lwe-cardiovascular, kunye nokuzalisa i-periodontal cavity. Ngokunzulu kophando kwi-β-tricalcium phosphate, iifom zayo zesicelo nazo ziye zahluka, kwaye zibonise ukusebenza kakuhle kumayeza ekliniki.
