Abstract: Resorpsi tulang alveolar setelah pencabutan gigi dapat menurunkan volume tulang dan menyulitkan pemasangan implan, sehingga diperlukan biomaterial pengisi soket yang mampu terdegradasi seiring pembentukan tulang baru. Salah satu biomaterial yang berpotensi digunakan adalah nano ß-trikalsium fosfat (ß-TKF). Penelitian ini bertujuan mensintesis nano ß-trikalsium fosfat (ß-TKF) dan mengevaluasi karakteristik fisikokimia, biodegradabilitas, serta bioaktivitasnya secara in vitro. Hasil XRD dan FTIR mengonfirmasi pembentukan fase ß-TKF, sedangkan SEM-EDX dan PSA mengkonfirmasi morfologi partikel berukuran nano dengan rasio Ca/P mendekati stoikiometri. Uji biodegradabilitas menunjukkan nano ß-TKF mengalami penurunan massa dan laju degradasi yang lebih tinggi dibandingkan ß-TKF kontrol. Uji bioaktivitas memperlihatkan terbentuknya fase hidroksiapatit (HA) sebagai mineral alami penyusun tulang. Hasil ini menunjukkan bahwa nano ß-TKF berpotensi dikembangkan sebagai biomaterial alternatif untuk preservasi tulang alveolar.
Alveolar bone resorption after tooth extraction can reduce bone volume and complicate implant placement, requiring a socket-filling biomaterial that can degrade along with new bone formation. One potential biomaterial is nano ß-tricalcium phosphate (ß-TKF). This study aimed to synthesize nano ß-tricalcium phosphate (ß-TKF) and evaluate its physicochemical characteristics, biodegradability, and bioactivity in vitro. XRD and FTIR results confirmed the formation of the ß-TKF phase, while SEM-EDX and PSA confirmed the morphology of nano-sized particles with a Ca/P ratio close to stoichiometric. Biodegradability tests showed that nano ß-TKF experienced a higher mass reduction and degradation rate compared to the control ß-TKF. Bioactivity tests showed the formation of a hydroxyapatite (HA) phase as a natural mineral constituent of bone. These results indicate that nano ß-TKF has the potential to be developed as an alternative biomaterial for alveolar bone preservation.
