Abstract


Introduction: Resin Heat-polymerized acrylic resin is commonly used to fabricate denture bases; however, it has several disadvantages, including low impact strength, which makes it more susceptible to fracture. This limitation may be addressed by adding betung bamboo fiber nanocellulose as a reinforcing material. Nanocellulose has smaller particle sizes and greater homogeneity. This study aimed to analyze the effect of adding betung bamboo fiber nanocellulose at concentrations of 0.5%, 0.75%, and 1% to heat-polymerized acrylic resin denture bases on impact strength. Methods: This was an experimental laboratory study. Heat-polymerized acrylic resin denture base specimens without added betung bamboo fiber nanocellulose served as the control group (Group A). Specimens with 0.5% (Group B), 0.75% (Group C), and 1% (Group D) betung bamboo fiber nanocellulose served as the treatment groups. A total of 32 specimens measuring 65 × 10 × 2.5 mm were prepared using a brass metal mold. The specimens were tested using the Charpy impact test to determine impact strength. Results: The mean ± standard deviation impact strength values were 9.99 ± 1.63 × 10⁻³ J/mm² for Group A, 12.05 ± 0.84 × 10⁻³ J/mm² for Group B, 13.8 ± 0.75 × 10⁻³ J/mm² for Group C, and 14.58 ± 0.88 × 10⁻³ J/mm² for Group D. One-way ANOVA showed a significant difference (p=0.0001; p<0.05), and the LSD test also showed a significant difference (p=0.0001; p<0.05). Conclusion: The addition of betung bamboo fiber nanocellulose to heat-polymerized acrylic resin denture base material had a significant effect on impact strength.

Perbedaan efek penambahan nanoselulosa serat bambu betung pada bahan basis gigi tiruan resin akrilik polimerisasi panas terhadap kekuatan impak: studi eksperimental

Pendahuluan: Resin akrilik polimerisasi panas sering digunakan untuk membuat basis gigi tiruan, namun RAPP memiliki kekurangan diantaranya kekuatan impak yang rendah sehingga lebih mudah terjadi fraktur. Hal ini dapat diatasi dengan menambahkan bahan penguat nanoselulosa serat bambu betung. Nanoselulosa memiliki ukuran partikel yang lebih kecil serta memiliki homogenitas yang lebih baik. Penelitian ini bertujuan untuk menganalisis perbedaan efek penambahan nanoselulosa serat bambu betung dengan konsentrasi 0,5%, 0,75%, dan 1% pada basis gigi tiruan RAPP terhadap kekuatan impak. Metode: Penelitian ini adalah penelitian eksperimental laboratoris. Penelitian ini dilakukan pada sampel basis gigi tiruan resin akrilik polimerisasi panas dengan kelompok tanpa penambahan nanoselulosa serat bambu betung sebagai kelompok kontrol (kelompok A) dan dengan penambahan nanoselulosa serat bambu betung 0,5% (kelompok B), 0,75% (kelompok C) dan 1% (kelompok D) sebagai kelompok perlakuan. Sampel dibuat dengan ukuran 65×10×2,5 mm sebanyak 32 sampel, dan berbentuk logam kuningan. Sampel diuji dengan Uji impak charpy untuk menganalisis nilai kekuatan impak. Hasil: Nilai rata-rata dan standar deviasi kekuatan impak pada kelompok A sebesar 9,99 ± 1,63 x 10-3 J/mm2, kelompok B sebesar 12,05 ± 0,84 x 10-3 J/mm2, kelompok C sebesar 13,8 ± 0,75 x 10-3 J/mm2 dan kelompok D sebesar 14,58 ± 0,88 x 10-3 J/mm2. Hasil uji ANOVA satu arah diperoleh nilai signifikansi p=0,0001 (p<0,05) dan uji LSD yang signifikan dengan nilai p = 0,0001 (p<0.05). Simpulan: Terdapat perbedaan efek penambahan nanoselulosa serat bambu betung pada bahan basis gigi tiruan resin akrilik polimerisasi panas terhadap kekuatan impak.
