Chigawo cha β-TCP ndi chofanana ndi fupa la mchere ndipo ndi ufa woyera wa amorphous wopanda fungo. Khola mu mpweya, decomposed mu madzi otentha, sungunuka mu kuchepetsa hydrochloric acid ndi asidi nitric, pafupifupi insoluble m'madzi, Mowa ndi asidi asidi. Kugwirizana kwachilengedwe kwachilengedwe, kuwonongeka pansi pa chilengedwe, kuyamwa ndi minyewa.
β-tricalcium phosphate (β-TCP) ili ndi biodegradability yabwino, biocompatibility ndi osteoinductive luso. Pambuyo pa kuikidwa m'thupi la munthu, kashiamu yowonongeka ndi phosphorous imatha kulowa m'thupi ndikupanga fupa latsopano, choncho amagwiritsidwa ntchito kwambiri. Konzani minofu ya mafupa. Komabe, kulimba kwake kumakhala kocheperako, kofewa, komanso kunyamula katundu ndikotsika. Poly L-lactic acid (PLLA) yagwiritsidwanso ntchito pokonzanso minofu ya mafupa chifukwa cha biocompatibility yake yabwino komanso kuwonongeka kwachilengedwe.
Tricalcium phosphate ili ndi biocompatibility yabwino, bioactivity ndi biodegradability. Ndi njira yabwino yokonza minofu yolimba ndikusintha m'malo mwa thupi la munthu ndipo yakhala ikuyang'aniridwa kwambiri pankhani ya uinjiniya wa biomedical. Mtundu wapadera wa tricalcium phosphate, beta-tricalcium phosphate, amagwiritsidwa ntchito kwambiri pazamankhwala. Kuyanjana kwabwino kwachilengedwe, bioactivity ndi biodegradability. Ndilofunika kukonza minofu yolimba ndikusintha zina. Monga zopangira fupa lopanga, lakhala likugwiritsidwa ntchito kwambiri m'mafupa, opaleshoni ya pulasitiki ndi opaleshoni yodzikongoletsera, opaleshoni ya mano, kukonza chifukwa cha kuvulala, kuwonongeka kwa mafupa ndi kusakanikirana kwa mafupa chifukwa cha zotupa, kutupa, matenda a mafupa, ndi zina zotero. ku zakudya monga chowonjezera chopatsa thanzi chothandizira kukulitsa kashiamu, komanso chitha kugwiritsidwa ntchito popewa kapena kuchiza zizindikiro za kuchepa kwa calcium. Nthawi yomweyo, itha kugwiritsidwanso ntchito ngati anti-caking agent, pH adjuster, buffering agent, etc. muzakudya.
β-tricalcium phosphate makamaka amapangidwa ndi kashiamu ndi phosphorous, ndipo kapangidwe kake n'kofanana ndi chigawo chimodzi cha fupa masanjidwewo, ndipo bwino pamodzi ndi fupa. Zinyama kapena maselo aumunthu amatha kukula, kusiyanitsa ndi kuchulukana pa zinthu za β-tricalcium phosphate. Kupyolera mu kafukufuku wambiri woyesera, zatsimikiziridwa kuti β-tricalcium phosphate alibe zotsatira zotsutsana ndi ntchito ya m'mafupa a hematopoietic, palibe kukana, palibe kuopsa kwa poizoni, palibe khansa, palibe chodabwitsa. Chifukwa chake, β-tricalcium phosphate imatha kugwiritsidwa ntchito kwambiri pophatikizana ndi kuphatikizika kwa msana, kuvulala kwa miyendo, opaleshoni yapakamwa ndi maxillofacial, opaleshoni yamtima, komanso kudzaza gawo la periodontal. Ndi kuzama kwa kafukufuku wa β-tricalcium phosphate, mafomu ake ogwiritsira ntchito asinthanso, ndipo awonetsa kuchita bwino kwamankhwala azachipatala.
