Abstract: Composite resin is one of the restoration material used in dental practice. Its strength and resistance factors toward usage and stability dimension lead to high compression strength to withstand mastication burden. This capacity has to be considered in choosing the composite resin as restoration material. This study was aimed to compare the compression strength of resin composites formed with horizontal incremental restoration technique and with bulk restoration technique. This was an experimental study conducted at Material Engineering Laboratory of the Faculty of Engineering Sam Ratulangi University Manado. There were six samples divided into 2 groups, each of 3 samples. The results showed that compression strength of resin composite formed with horizontal incremental technique was 199.45 MPa meanwhile of resin composite formed with bulk technique was 191.65 MPa. Conclusion: Compression strength of resin composite formed with horizontal incremental technique was higher than of resin composite formed with bulk technique.

Abstrak: Resin komposit merupakan salah satu bahan restorasi yang sering digunakan di kedokteran gigi. Faktor kekuatan dan ketahanan terhadap penggunaan dan stabilitas dimensi memungkinkannya memiliki kekuatan kompresi yang besar untuk menahan beban kunyah. Hal ini merupakan salah satu keunggulan yang menjadi dasar pertimbangan saat memilih resin komposit sebagai bahan tumpatan. Penelitian ini bertujuan untuk mengetahui perbandingan teknik penumpatan incremental horizontal dan teknik penumpatan bulk untuk kekuatan kompresi resin komposit. Jenis penelitian ialah eksperimental yang dilakukan di Laboratorium Rekayasa Material Fakultas Teknik Universitas Sam Ratulangi. Sampel berjumlah 6 buah dibagi menjadi 2 kelompok, masing-masing terdiri dari 3 sampel. Hasil penelitian menunjukkan bahwa kekuatan kompresi tumpatan resin komposit dengan teknik incremental horizontal sebesar 199,45 MPa dan tumpatan resin komposit dengan teknik bulk sebesar 191,65 MPa. Simpulan: Kekuatan tekanan kompresi tumpatan resin komposit menggunakan teknik incremental horizontal lebih tinggi dibandingkan dengan menggunakan teknik bulk.
