Gawo la β-TCP ndi lofanana ndi kapangidwe ka mchere wa mafupa ndipo ndi ufa woyera wopanda fungo. Wokhazikika mumlengalenga, wosungunuka m'madzi otentha, wosungunuka mu hydrochloric acid wosungunuka ndi nitric acid, wosasungunuka m'madzi, ethanol ndi acetic acid. Kugwirizana kwabwino kwa zamoyo, kuwonongeka pansi pa chilengedwe, kuyamwa ndi minofu.
β-tricium phosphate (β-TCP) ili ndi mphamvu yabwino yowola, yogwirizana ndi thupi, komanso yothandiza mafupa. Pambuyo poyikidwa m'thupi la munthu, calcium ndi phosphorous zomwe zawonongeka zimatha kulowa m'thupi ndikupanga fupa latsopano, motero zimagwiritsidwa ntchito kwambiri. Konzani minofu ya mafupa. Komabe, kulimba kwake ndi kochepa, kofooka, ndipo mphamvu yake yonyamula katundu ndi yofooka. Poly L-lactic acid (PLLA) yagwiritsidwanso ntchito pokonza minofu ya mafupa chifukwa cha mphamvu yake yabwino yogwirizana ndi thupi komanso yowola.
Tricalcium phosphate ili ndi biocompatibility yabwino, bioactivity komanso biodegradable. Ndi chinthu chabwino kwambiri chokonzanso ndi kusintha minofu yolimba m'thupi la munthu ndipo chakhala chikuyang'aniridwa bwino m'munda wa uinjiniya wa zamankhwala. Mtundu wapadera wa tricalcium phosphate, beta-tricium phosphate, umagwiritsidwa ntchito kwambiri mu zamankhwala. Biocompatibility yabwino, bioactivation ndi biodegradable. Ndi chinthu chabwino kwambiri chokonzanso ndi kusintha minofu yolimba. Monga chinthu chopangira mafupa opangidwa, chagwiritsidwa ntchito kwambiri mu opaleshoni ya mafupa, opaleshoni ya pulasitiki ndi opaleshoni yokongoletsa, opaleshoni ya mano, kukonza chifukwa cha kuvulala, zolakwika za mafupa ndi kuphatikizika kwa mafupa komwe kumachitika chifukwa cha zotupa, kutupa, matenda a mafupa, ndi zina zotero. Ikhoza kuwonjezeredwa muzakudya ngati chowonjezera chotetezeka cha zakudya kuti chiwonjezere kudya kwa calcium, ndipo ingagwiritsidwenso ntchito kupewa kapena kuchiza zizindikiro za kusowa kwa calcium. Nthawi yomweyo, ingagwiritsidwenso ntchito ngati choletsa kuyika, chosinthira pH, choletsa kutsekeka, ndi zina zotero muzakudya.
β-triccalcium phosphate imapangidwa makamaka ndi calcium ndi phosphorous, ndipo kapangidwe kake ndi kofanana ndi gawo losapangidwa la fupa, ndipo limagwirizanitsidwa bwino ndi mafupa. Zinyama kapena maselo a anthu amatha kukula, kusiyanitsa ndi kuchulukana pa zinthu za β-triccalcium phosphate. Kudzera mu kafukufuku wambiri woyesera, zatsimikiziridwa kuti β-triccalcium phosphate ilibe zotsatira zoyipa ku ntchito ya hematopoietic ya m'mafupa, palibe kukana, palibe poizoni, palibe khansa, palibe ziwengo. Chifukwa chake, β-tricium phosphate ingagwiritsidwe ntchito kwambiri polumikizana mafupa ndi msana, kuvulala kwa miyendo, opaleshoni ya pakamwa ndi maxillofacial, opaleshoni ya mtima, komanso kudzaza periodontal cavity. Ndi kuzama kwa kafukufuku pa β-tricium phosphate, mitundu yake yogwiritsira ntchito yasinthanso, ndipo yawonetsa kugwira ntchito bwino mu zamankhwala azachipatala.
