SINTESIS DAN KARAKTERISASI MEMBRAN KOMPOSIT KITOSANHIDROKSI APATIT BERIKATAN SILANG SEBAGAI GUIDED TISSUE REGENERATION (GTR)[Synthesis and Characterization of the Chitosan (Cs)-Hydroxyapatite (Ha) Crosslinked Composite Membrane for Guided Tissue Regeneration (GTR)]
Abstract
SINTESIS DAN KARAKTERISASI MEMBRAN KOMPOSIT KITOSAN- HIDROKSI APATIT
BERIKATAN SILANG SEBAGAI GUIDED TISSUE REGENERATION (GTR). Dalam kerangka
mempersiapkan bahan biomaterial untuk guided tissue regeneration (GTR), telah dilakukan sintesis membran
kitosan –hidroksiapatit (HA) berikatan silang dan karakterisasi sifat fisiko-kimianya. HA dengan variasi berat (2-
6 g) dicampurkan dengan larutan kitosan 4%, diproses hingga berbentuk komposit membran dan di crosslink
dalam larutan natrium sulfit (Na2SO3). Perubahan struktur kimia dan morphologi membran dikarakterisasi
mengggunakan fourier transform infra red (FTIR) dan scanning electron microscope (SEM). Hasil evaluasi
menunjukkan membran dapat menyerap air relatif cepat (5 menit) dan tidak terjadi peningkatan penyerapan air
dengan meningkatnya waktu. Meningkatnya berat HA menyebabkan meningkatnya biodegradasi membran,
sebaliknya kekuatan tarik dan elongasi dari membran menurun. Hasil analisis FTIR menunjukkan membran
Kitosan-HA berikatan silang. Membran Kitosan-HA selayaknya dapat dipertimbangkan untuk digunakan
sebagai membran GTR (Guided Tissue Regeneration) dalam bidang periodontal.
Abstract
In the preparation of biomaterials to be useful for guided tissue regeneration (GTR), the chitosan (CS)-
hydroxyapatite (HA) crosslinked membrane has been synthesized and characterization its physico-chemical.
HA with varying weight ( 2- 6 g) was mixed with 4% CS solution and processed to composite membrane,
and then crosslinking with sodium sulfite (Na2SO3). Chemical structure and morphology of membranes
were characterized using Fourier Transform Infra Red spectrophotometer (FTIR) and Scanning Electron
Microscope (SEM) The results showed that the membrane capable to absorb water relatively fast (5 min)
and stable with the increase of time. With increasing of HA content, the biodegradation of membranes
increase. In contrast, the tensile strength and elongation at break of membranes decrease. FTIR spectra
showed a crosslinking CS-HA membrane. The CS-HA composite membrane could be considered to be used
as GTR (Guided Tissue Regeneration ) membrane in periodontal.
