Imibuzo Ebuzwa Rhoqo (FAQ)

Uthini umahluko phakathi kwe-hydroxyapatite kunye ne-tricalcium phosphate?

Nangona zombini i-calcium phosphates, i-hydroxyapatite (HAp) izinzile kwaye inyibilika kancinane kune-beta-tricalcium phosphate (β-TCP). I-HAp ngokuyintloko i-osteoconductive (ixhasa ukukhula kwamathambo kumphezulu wayo), kanti i-β-TCP i-osteoinductive kwaye i-resorbable, isetyenziswa rhoqo apho kufuneka ukutshintshwa kwethambo ngokuhamba kwexesha. Iigrafti ezininzi zanamhlanje zisebenzisa i-biphasic calcium phosphate (BCP), umxube wazo zombini, ukulinganisa ukuzinza kunye nokuphinda kufakwe kwakhona.

Ngaba i-hydroxyapatite powder ikhuselekile ekusebenziseni izimonyo?

Ewe, i-hydroxyapatite yokwenziwa ithathwa njengekhuselekile ukusetyenziswa kwizithambiso. Ayinamsindo kwaye iyahambelana nebhayoloji.
