Abstract
Denture Base atau gusi buatan adalah bagian dari denture atau gigi palsu yang memiliki peran penting dalam mendistribusikan gaya yang diterima oleh mahkota gigi pada tulang rahang. Dalam membuat denture base, diperlukan sifat mekanik dan physicochemical yang unggul. Salah satu material yang umum digunakan adalah poly-methyl methacrylate (PMMA). Material ini dipilih karena memiliki sifat mekanik dan sifat physicochemical yang dibutuhkan seperti bio-compatibility yang baik. Saat ini, pembuatan denture base umumnya menggunakan metode konvensional dengan pencetakan manual yang membutuhkan proses lebih lama, finishing lebih lanjut, dan menghasilkan sampah cukup banyak. Seiring dengan perkembangan teknologi Additive Manufacturing (AM) atau biasa disebut 3D Printing, maka bidang kedokteran gigi juga ikut memanfaatkan teknologi ini untuk memproduksi gigi buatan termasuk denture base dan crown gigi. Teknologi AM dipilih karena kemampuannya dalam mencetak produk dengan ketelitian tinggi, waktu yang relatif cepat, dan waste yang relatif sedikit dibanding metode manufacturing lainnya. Tujuan dalam penelitian ini adalah untuk membandingkan pengaruh arah pencetakan dari dua jenis 3D Printing yaitu Fused Deposition Modelling (FDM) dan Digital Light Projection (DLP) terhadap sifat mekanik produk yang dihasilkan. Variasi arah pencetakan yang digunakan adalah arah orientasi X, Y, dan Z. Untuk menguji sifat mekanik dari tiap variasinya, akan digunakan Tensile Test, Compression Test, dan Three-Point Bending Test untuk mendapatkan tensile, compression, dan flexural properties. Setelah dilakukan berbagai pengujian, diketahui bahwa spesimen yang dibuat menggunakan metode DLP lebih unggul ultimate tensile strength dan ultimate flexural strength dengan nilai sekitar dua kali dari spesimen FDM dan pola kegagalan getas. Spesimen DLP juga memiliki kekakuan yang tinggi dan minim deformasi plastis dengan karakteristik brittle polymer. Di sisi lain, spesimen dengan metode FDM mengalami regangan yang tinggi saat tejadi deformasi plastis yang signifikan. Spesimen FDM lebih mampu menahan beban kompresi karena kemampuannya dalam berdeformasi plastik. Dalam hal pembuatan denture base, dibutuhkan kekakuan yang tinggi sehingga metode DLP lebih cocok digunakan sebagai metode pembuatan denture base karena pada denture base tidak boleh terjadi deformasi plastik saat digunakan.

Denture Base or artificial gum is a part of denture or denture that has an important role in distributing the force received by the crown of the tooth on the jawbone. In making denture bases, superior mechanical and physicochemical properties are required. One of the commonly used materials is poly-methyl methacrylate (PMMA). This material was chosen because it has the required mechanical properties and physicochemical properties such as good bio-compatibility. Currently, the manufacture of denture base generally uses conventional methods with manual printing which requires a longer process, further finishing, and produces quite a lot of waste. Along with the development of Additive Manufacturing (AM) technology or commonly called 3D Printing, the field of dentistry also utilizes this technology to produce artificial teeth including denture bases and dental crowns. AM technology was chosen because of its ability to print products with high accuracy, relatively fast time, and relatively little waste compared to other manufacturing methods. The purpose of this study is to compare the influence of printing direction of two types of 3D Printing, namely Fused Deposition Modeling (FDM) and Digital Light Projection (DLP) on the mechanical properties of the resulting product. The variations in printing directions used are the orientation directions X, Y, and Z. To test the mechanical properties of each variation, Tensile Test, Compression Test, and Three-Point Bending Test will be used to obtain tensile, compression , and flexural properties. After various tests, it was found that specimens made using the DLP method were superior to ultimate tensile strength and ultimate flexural strength with values about twice that of FDM specimens and brittle failure patterns. DLP specimens also have high rigidity and minimal plastic deformation with brittle polymer characteristics. On the other hand, specimens with the FDM method experience high strain when significant plastic deformation occurs. FDM specimens are better able to withstand compression loads due to their ability to deform plastics. In the case of making denture bases, high rigidity is needed so that the DLP method is more suitable to be used as a method of making denture bases because the denture base must not deform plastic when used.
