Icandelo le-β-TCP lifana nokwakheka kweminerali yamathambo kwaye liyimpuphu emhlophe engenavumba. Izinzile emoyeni, ibolile emanzini ashushu, iyanyibilika kwi-hydrochloric acid enyibilikisiweyo kunye ne-nitric acid, ayinyibiliki emanzini, i-ethanol kunye ne-acetic acid. Ihambelana kakuhle nebhayoloji, iyawohloka phantsi kwendalo ye-physiological, ifunxwa zizicubu.
I-β-tricium phosphate (β-TCP) iyakwazi ukubola, ukuhambelana komzimba kunye nokukwazi ukubola kwamathambo. Emva kokuba ifakwe emzimbeni womntu, i-calcium kunye ne-phosphorus eyonakalisiweyo zinokungena kwinkqubo ephilayo kwaye zenze ithambo elitsha, ngoko ke isetyenziswa kakhulu. Lungisa izicubu zamathambo. Nangona kunjalo, ukuqina kwayo akukuhle, kuyaphuka, kwaye amandla okuthwala umthwalo aphantsi. I-Poly L-lactic acid (PLLA) ikwasetyenziswa ekulungiseni izicubu zamathambo ngenxa yokuhambelana kwayo kakuhle kunye nokubola komzimba.
I-Tricalcium phosphate iyakwazi ukuhambelana kakuhle ne-biocompatibility, i-bioactivity kunye ne-biodegradability. Yinto efanelekileyo yokulungisa nokutshintsha izicubu eziqinileyo zomzimba womntu kwaye ijongiwe kakhulu kwicandelo lobunjineli be-biomedical. Uhlobo olukhethekileyo lwe-tricalcium phosphate, i-beta-tricium phosphate, isetyenziswa kakhulu kwezonyango. Isebenza kakuhle kwi-biocompatibility, i-bioactivity kunye ne-biodegradability. Yinto efanelekileyo yokulungisa nokutshintsha izicubu eziqinileyo. Njengezinto eziluhlaza zethambo elenziweyo, isetyenziswa kakhulu kwi-orthopedics, utyando lweplastiki kunye notyando lobuhle, utyando lwamazinyo, ukulungiswa ngenxa yokwenzakala, iziphene zamathambo kunye nokudibana kwamathambo okubangelwa ziithumba, ukudumba, izifo zamathambo, njl. Ingongezwa ekutyeni njengesongezelelo sesondlo esikhuselekileyo sokwandisa ukutya kwe-calcium, kwaye ingasetyenziselwa ukuthintela okanye ukunyanga iimpawu zokungabikho kwe-calcium. Kwangaxeshanye, ingasetyenziswa njenge-arhente yokulwa nokubopha, i-pH adjuster, i-arhente ye-buffering, njl. ekutyeni.
I-β-tricium phosphate yenziwe kakhulu nge-calcium kunye ne-phosphorus, kwaye ukwakheka kwayo kufana nenxalenye engaphiliyo ye-bone matrix, kwaye idibene kakuhle nethambo. Izilwanyana okanye iiseli zabantu zinokukhula, zahluke kwaye zande kwizinto ze-β-tricium phosphate. Ngenani elikhulu lezifundo zovavanyo, kubonakalisiwe ukuba i-β-tricium phosphate ayinazo iziphumo ezibi kumsebenzi we-hematopoietic womongo wethambo, akukho mpendulo yokulahlwa, akukho mpendulo yobuthi obubukhali, akukho mhlaza, akukho nto ibangela i-allergy. Ke ngoko, i-β-tricium phosphate ingasetyenziswa kakhulu ekuhlanganiseni amalungu kunye nomqolo, ukwenzakala kwamalungu, utyando lomlomo kunye ne-maxillofacial, utyando lwentliziyo, kunye nokuzalisa umgodi we-periodontal. Ngokunzulu kophando kwi-β-tricium phosphate, iifom zayo zokusetyenziswa nazo ziye zahluka, kwaye ibonakalise ukusebenza kakuhle kunyango lwezonyango.
