Abstract

ABSTRAK

Pendahuluan: Resin akrilik polimerisasi panas merupakan bahan basis gigi tiruan yang sering digunakan karena memiliki sifat estetis yang baik, mudah direparasi dan tidak toksik. Namun, juga memiliki sifat mekanis yang rendah adalah kekasaran permukaan, sehingga diperlukan penambahan bahan penguat pada resin akrilik polimerisasi panas, yaitu silika dari abu cangkang kelapa sawit. Penelitian ini bertujuan untuk menganalisis perbedaan efek penambahan silika 2% dan 5% dari abu cangkang kelapa sawit pada basis gigi tiruan resin akrilik polimerisasi panas terhadap kekasaran permukaan. Metode: Jenis penelitian ini adalah eksperimental laboratorium yang dilakukan pada sampel basis gigi tiruan resin akrilik polimerisasi panas yang ditambahkan bahan penguat silika 2% dan 5%. Dengan sampel (65x10x2,5) mm berdasarkan ISO 1567. Total sampel sebanyak 30 buah dibagi menjadi 3 kelompok, kelompok tanpa silika dan kelompok B, C; kelompok dengan penambahan silika konsentrasi 2% dan 5%. Uji kekasaran permukaan sampel dilakukan menggunakan Profilometer (Mitutoyo SURFTEST SJ-210, Japan). Sampel dianalisis dengan uji one way Anova dan LSD. Hasil: uji ANOVA menunjukkan adanya pengaruh penambahan silika 2% dan 5% pada kekasaran permukaan basis gigi tiruan resin akrilik polimerisasi panas, dengan nilai p=0,001 (p<0,05). Uji LSD menunjukkan adanya perbedaan bermakna antara kelompok kontrol dengan kelompok penambahan silika 2%, antara kelompok kontrol dengan kelompok penambahan silika 5%, serta antara kelompok penambahan silika 2% dan 5%, dengan nilai p=0,001 (p<0,005). Simpulan: Terdapat perbedaan nilai kekasaran permukaan pada bahan basis gigi tiruan RAPP tanpa atau dengan penambahan silika 2% dan 5%

The Effect of the Addition of Silica from Palm Shell Ash to the surface roughness of heat-polymerized acrylic resin Denture Base: Study experimental

ABSTRACT

Introduction: Heat polymerized acrylic resin is one of the most frequently used for denture base materials because it has good aesthetic properties, easy to repair and non-toxic. However, it also has low mechanical properties such as surface roughness, so modification is needed by adding a reinforcing material to the heat polymerized acrylic resin in the form of silica from palm shell ash. This aims of this study is to analyze the effect of adding 2% and 5% silica from palm shell ash to the heat polymerized acrylic resin denture base on its surface roughness. Methods: This type of research is a laboratory study with a sample’s size of 65x10x2.5 mm; based on ISO 1567. A total of 30 samples were divided into 3 groups, i.e. group A (without reinforcing materials) as a control group and group B and C were group silica addition with concentrations of 2% and 5%. Surface roughness tests on the samples were conducted using a Profilometer (Mitutoyo SURFTEST SJ-210, Japan) The samples were analyzed by one way Anova and LSD tests. Results: ANOVA test results that there is an effect of adding 2% and 5% silica from palm shell ash on the surface roughness of heat polymerized acrylic resin dentures; with a value of p = 0.001 (p <0.05). The results of the LSD test showed a significant difference between group control (without the addition of silica) and 2% silica, between control group with the addition of 5% silica, and between group adding 2% and 5% silica; with a value of p = 0.001 (p <0.005). Conclusion: There is a difference in surface roughness values in the denture base material RAPP with or without the addition of 2% and 5% silica.
